Description

Technical Field

[0001] The present application relates to the technical field of cameras, and in particular to a stabilizing device and a camera apparatus. Background Art

[0002] With the continuous development of social economy and technology, people have become accustomed to using cameras and other equipment to record images and audio and video materials, whether at work or in daily life. In order to adjust the shooting distance and angle, stabilize the shooting picture, and obtain better shooting effects, various stabilization devices have emerged.

[0003] In the prior art, the stabilization device usually includes a posture sensor, a controller, and a drive motor. The posture sensor is fixedly connected to the camera to detect the posture of the camera in real time, and the detected posture signal is transmitted to the controller through a transmission line or wireless communication. The controller controls the drive motor based on the detection signal so that the stabilization device maintains the posture of the camera. However, the communication method of the transmission line limits the rotation angle of the camera, resulting in blind spots in the shooting, which cannot meet the shooting requirements; the wireless communication method will have a delay problem. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of this application is to provide a stabilizing device and a camera device to ensure the data transmission rate, ensure the balance and stability of the camera, and also ensure that the camera can be rotated and filmed at any angle. The specific technical solutions include the following:

[0005] In a first aspect, an embodiment of the present application provides a stabilizing device, comprising:

[0006] A connection socket, used to fix the electronic device;

[0007] An inner ring, used to fix the connecting seat;

[0008] The outer ring is coaxially sleeved on the outer side of the inner ring and is rotatably connected with the inner ring;

[0009] A circumferential connection unit, comprising an inner ring and an outer ring which are electrically connected, wherein the inner ring is fixed to the outer circumference of the inner ring, and the outer ring is fixed to the inner circumference of the outer ring;

[0010] The connection socket includes a transmission line, one end of which is connected to the inner circle of the circumferential connection unit, and the other end is connected to the electronic device. The electronic device electrically transmits signals to an external device through the transmission line and the circumferential connection unit.

[0011] The present application indirectly fixes the electronic device to the inner ring by using a connecting seat, and at the same time, coaxially arranges an outer ring outside the inner ring, and rotatably connects it to the inner ring, so that the posture of the electronic device can be adjusted by adjusting the rotation angle between the inner ring and the outer ring. Furthermore, the present application also arranges a circumferential connection unit between the inner ring and the outer ring to allow the inner ring and the outer ring to rotate relative to each other while maintaining electrical connection, and ensures that electrical signals can be transmitted between the electronic device arranged on the inner ring side and the external device. That is, the present application realizes the transmission of electrical signals between the electronic device and the external device through the cooperation of the inner ring, the outer ring and the circumferential connection unit, and also liberates the rotational freedom of the electronic device relative to the stabilizing device, which can ensure that the posture of the electronic device can be rotated at any angle, including the angle adjustment of multiple continuous rotations, and can improve the transmission efficiency of electrical signals.

[0015] In this embodiment, by limiting the sum of the arcs of the inner and outer conductive arcs to be greater than 360 degrees, when the inner ring rotates at any angle relative to the outer ring with its own axis as the rotation center, the inner conductive arc can be in contact with the outer conductive arc for conduction, and the electrical signal of the electronic device is transmitted through the outer conductive arc or the electrical signal of the external device is transmitted to the electronic device through the inner conductive arc, thereby ensuring the reliability of signal transmission. That is, by limiting the sum of the arcs of the inner and outer conductive arcs to be greater than 360 degrees, it can be ensured that the electronic device can achieve 360-degree rotation or even multiple continuous rotations while being able to achieve electrical signal transmission with the external device.

After receiving the detection signal of the third posture sensor, the third drive motor controls the relative angle between the inner ring and the outer ring to keep the posture of the connecting seat relatively stable in the direction of freedom of relative rotation between the inner ring and the outer ring.

[0057] It should be noted in advance that the camera device provided by the present application may include an electronic device and a stabilizing device.

For the sake of ease of introduction, this application specification takes the electronic device including a camera as an example for elaboration.

[0060] Please refer to Figures 1 to 3 ,in Figure 1 A schematic structural diagram of a stabilizing device 100 provided in one embodiment of the present application from one side perspective; Figure 2 A schematic structural diagram of a stabilizing device 100 provided in one embodiment of the present application from another side perspective; Figure 3 for Figure 2 A partial enlarged view of point A in the middle.

[0061] like Figures 1 to 3 As shown, the stabilizing device 100 provided in the present application includes a connecting seat 10, an inner ring 20, an outer ring 30 and a circumferential connecting unit 40. Among them, the inner ring 20 and the outer ring 30 are both in the shape of a rotating body along the first axis 001, that is, along the axial direction of the inner ring 20 itself, and the outer ring 30 is sleeved on the outer circumference of the inner ring 20, and the connecting seat 10 is fixed to the inner circumference of the inner ring 20. In another embodiment, the connecting seat 10 can also be fixed to the side wall of the inner ring 20, and the camera is fixed on the connecting seat 10 (not shown in the figure). The rotational connection between the outer ring 30 and the inner ring 20 can ensure the connection and fixing effect between the outer ring 30 and the inner ring 20, and enable the outer ring 30 to rotate relative to the inner ring 20 with the first axis 001 as the rotation center. The stabilizer 100 of the present application can adjust the spatial posture of the camera and the shooting angle of the camera by adjusting the rotation angle between the inner ring 20 and the outer ring 30, so that when the external bracket 80 drives the stabilizer 100 and the camera to move or rotate, the stabilizer 100 can drive the camera to move in the opposite direction to compensate for the influence of the movement or rotation of the external bracket 80, thereby realizing the stabilization function of the camera. The stabilizer 100 of the present application also includes a movable bracket 50, which is connected to the outer ring 30 and is used to support the outer ring 30 to indirectly support the camera. The external device can usually be fixed to the side of the outer ring 30 (not shown in the figure), for example, it can be fixed to the outer surface of the outer ring 30, or it can be fixed to the movable bracket 50, etc., as long as it is not fixed to the inner ring 20, and the present application does not make any special restrictions on this.

[0062] For further information, please refer to Figure 4 The figure shows an exploded schematic diagram of a circumferential connection unit 40 provided in one embodiment of the present application.

[0063] like Figures 1 to 4As shown, the present application sets the circumferential connection unit 40 between the inner ring 20 and the outer ring 30. Specifically, the circumferential connection unit 40 includes an inner ring 41 and an outer ring 42. The inner ring 41 is fixed to the outer circumference of the inner ring 20, and the outer ring 42 is fixed to the inner circumference of the outer ring 30. When the inner ring 20 rotates relative to the outer ring 30 around the first axis 001, the inner ring 41 also rotates relative to the outer ring 42 around the first axis 001. At the same time, the inner ring 41 is also electrically connected to the outer ring 42. That is, the inner ring 41 and the outer ring 42 are also coaxially arranged, and can rotate relative to each other around the first axis 001 while maintaining electrical connection. The connection seat 10 is also provided with a transmission line 11, one end of the transmission line 11 is connected to the camera, and the other end is connected to the inner ring 41, so as to conduct the camera with the inner ring 41. At the same time, based on the electrical connection between the inner ring 41 and the outer ring 42, the camera can be conducted to the external device through the transmission line 11 and the circumferential connection unit 40.

[0064] It can be understood that, since the camera, the connection seat 10 and the inner ring 41 are all fixed relative to the inner ring 20, when the inner ring 20 is rotated to any angle relative to the outer ring 30, the transmission line 11 will not be pulled. Or it can be understood that the setting of the transmission line 11 of the present application will not constrain the rotation angle of the camera relative to the external device, and can ensure that the camera and the external device can transmit electrical signals while being able to rotate at any angle, including multiple continuous rotations to adjust the shooting angle. That is, the present application, through the cooperation of the inner ring 20, the outer ring 30 and the circumferential connection unit 40, enables the camera to transmit electrical signals to the external device while also liberating the rotational freedom of the camera relative to the stabilizing device 100, and can ensure that the posture of the camera can be rotated at any angle, including multiple continuous rotation angles, thereby realizing the stabilization function of the stabilizing device 100 on the camera. In addition, the transmission efficiency of electrical signals can be improved.

[0065] In one embodiment, the stabilizing device 100 of the present application includes a U-shaped frame, or it can be understood that the U-shaped frame is a movable bracket 50, which includes a chassis 51 and a swing arm 52. The chassis 51 is spaced apart from the outer ring 30, and the number of the swing arms 52 is two, and the two swing arms 52 are arranged on opposite sides of the outer ring 30 along the extension direction of the second axis 002. In this embodiment, the first axis 001 and the second axis 002 are perpendicular to each other, that is, the extension direction of the second axis 002 is parallel to the radial direction of the outer ring 30. At this time, the two swing arms 52 are arranged on opposite sides of the outer ring 30 along the radial direction of the outer ring 30, that is, they are arranged on opposite sides of the chassis 51. It can also be understood that the two swing arms 52 are symmetrical with respect to the chassis 51 and are spaced apart along the radial direction of the outer ring 30. Each swing arm 52 is connected between the chassis 51 and the outer ring 30, so that the swing arm 52 can support the outer ring 30 to indirectly support the camera, and the chassis 51 can be used to fix an external device (not shown in the figure). Furthermore, one end of each swing arm 52 is fixedly connected to the chassis 51, and the other end is rotatably connected to the outer ring 30, so that the swing arm 52 can realize the supporting function for the outer ring 30, and the outer ring 30 can also rotate around the second axis 002 relative to the swing arm 52, that is, the rotational freedom of the stabilizing device 100 is increased. By adjusting the rotation angle of the outer ring 30 relative to the swing arm 52, the posture of the electronic device can be further adjusted, so that the stabilizing device 100 can adjust the shooting angle of the camera in two dimensions.

[0066] In one embodiment, the camera device of the present application further includes an external bracket 80, which is rotatably connected to the chassis 51 with the third axis 003 as the rotation center. For example, the third axis 003 is perpendicular to the first axis 001 and the second axis 002. The external bracket 80 is used to support the chassis 51, while ensuring that the chassis 51 can rotate relative to the external bracket 80 to adjust the posture of the chassis 51, so that the stabilizing device 100 can adjust the shooting angle of the camera in three dimensions.

[0067] It should be noted that, in other embodiments, the first axis 001, the second axis 002 and the third axis 003 can be arranged to intersect at any angle in space. As long as the first axis 001, the second axis 002 and the third axis 003 are in a non-parallel spatial relationship, the stabilization device 100 of the present application can adjust the camera shooting angle in three dimensions.

[0068] exist Figure 1In the illustrated embodiment, the camera device of the present application further includes a drive motor 60 and a posture sensor 70. The number of the drive motor 60 and the posture sensor 70 are both multiple. Specifically, in one embodiment, the drive motor 60 includes a first drive motor 61, and the posture sensor 70 includes a first posture sensor 71. The first drive motor 61 and the first posture sensor 71 are both arranged between the swing arm 52 and the outer ring 30. Specifically, the first drive motor 61 is fixed to the end of the swing arm 52 connected to the outer ring 30, and is transmission-connected to the outer ring 30, and is used to drive the outer ring 30 to rotate around the second axis 002 relative to the swing arm 52, and maintain the posture of the outer ring 30 relative to the swing arm 52 stable. The first posture sensor 71 is fixed to the outer ring 30, and is used to detect the rotation posture of the outer ring 30 relative to the swing arm 52. At this time, the external device may include a controller, and the first posture sensor 71 is electrically connected to the controller, and transmits the detected rotation posture signal of the outer ring 30 relative to the swing arm 52 to the controller. The controller calculates the rotation posture of the outer ring 30 relative to the swing arm 52 based on the detection signal, and controls the first drive motor 61 to drive the outer ring 30 to rotate in the opposite direction relative to the swing arm 52 to compensate for the influence of the movement of the swing arm 52 on the posture of the outer ring 30, thereby maintaining the posture stability of the camera in the direction of the rotational freedom of the outer ring 30 relative to the swing arm 52.

[0069] It can be understood that when the swing arm 52 rotates a certain angle around the second axis 002 relative to the outer ring 30, the controller can control the first drive motor 61 to drive the outer ring 30 to rotate in the opposite direction around the second axis 002 at a corresponding angle, thereby ensuring that the camera maintains a stable posture in the direction of rotational freedom of the outer ring 30 relative to the swing arm 52, that is, in the rotation direction of the second axis 002, thereby realizing the stabilization function of the camera.

[0070] It should be noted that the positions of the first drive motor 61 and the first posture sensor 71 in the above-mentioned embodiment are only introduced as examples. For example, in another embodiment, the first posture sensor 71 can be fixed to the end where the swing arm 52 is connected to the outer ring 30, and the rotation posture of the outer ring 30 relative to the swing arm 52 can also be detected; and the first drive motor 61 can also be fixed to the outer ring 30 and connected to the swing arm 52 for transmission, and the rotation posture of the outer ring 30 relative to the swing arm 52 can also be adjusted. The present application does not make any special restrictions on this.

[0071] Further, the driving motor 60 of the present application further includes a second driving motor 62, and the posture sensor 70 further includes a second posture sensor (not shown in the figure). The second driving motor 62 is fixed to the external bracket 80 and is in transmission connection with the chassis 51, and is used to drive the chassis 51 to rotate relative to the external bracket 80 around the third axis 003, and maintain the stability of the posture of the chassis 51 relative to the external bracket 80. The second posture sensor is fixed to the chassis 51, and is used to detect the rotation posture of the chassis 51 relative to the external bracket 80. The second posture sensor is electrically connected to the controller, and transmits the detected rotation posture signal of the chassis 51 relative to the external bracket 80 to the controller. The controller calculates the rotation posture of the chassis 51 relative to the external bracket 80 based on the detection signal, and controls the second driving motor 62 to drive the chassis 51 to rotate in the opposite direction relative to the external bracket 80 to compensate for the influence of the movement of the external bracket 80 on the posture of the chassis 51, thereby maintaining the stability of the posture of the camera in the direction of the rotational freedom of the chassis 51 relative to the external bracket 80, thereby improving the stabilization performance of the camera.

[0072] In addition, in one embodiment, the driving motor 60 of the present application may further include a third driving motor 63, and the posture sensor 70 may further include a third posture sensor 73. Exemplarily, the third driving motor 63 is fixed to the outer ring 30 and is transmission-connected to the inner ring 20, and is used to drive the inner ring 20 to rotate relative to the outer ring 30 around the first axis 001, and maintain the posture stability of the inner ring 20 relative to the outer ring 30. The third posture sensor 73 is also fixed to the connecting seat 10. Based on the connection seat 10 being fixed to the inner ring 20, the third posture sensor 73 is used to detect the rotation posture of the connecting seat 10 relative to the outer ring 30, that is, to detect the rotation posture of the inner ring 20 relative to the outer ring 30. The third posture sensor 73 is electrically connected to the controller through the transmission line 11, the inner ring 41 and the outer ring 42 of the circumferential connection unit 40, and transmits the detected rotation posture signal of the inner ring 20 relative to the outer ring 30 to the controller. The controller calculates the rotation posture of the inner ring 20 relative to the outer ring 30 based on the detection signal, and controls the third drive motor 63 to drive the inner ring 20 to rotate in the opposite direction relative to the outer ring 30 to compensate for the influence of the movement of the outer ring 30 on the posture of the inner ring 20, thereby maintaining the posture stability of the camera in the direction of the rotational freedom of the inner ring 20 relative to the outer ring 30, thereby further improving the stabilization performance of the camera.

[0073] It can be understood that in the prior art, the third attitude sensor fixed to the connection seat and the controller fixed to the chassis usually transmit signals through wireless communication or only through the transmission line. The wireless communication transmission method will cause delay. As for the transmission method through the transmission line, since the inner ring will rotate in two dimensions relative to the chassis to achieve attitude adjustment, if the transmission line is short, the transmission line will be pulled during the attitude adjustment, which may cause the electrical connection to fail; if the transmission line is too long, the transmission line may be entangled and affect the operation. That is, the transmission method of the transmission line alone will limit the rotation angle of the inner ring relative to the chassis, resulting in the camera being unable to shoot or adjust the angle at any angle. However, the present application sets a circumferential connection unit 40 for signal transfer, so as to transmit the detection signal of the third attitude controller to the controller via the transmission line 11, the inner ring 41 and the outer ring 42 in sequence, thereby ensuring that the camera can shoot or adjust the angle at any angle, broadening the application scenario of the stabilizing device 100 and improving the compatibility of the stabilizing device 100.

[0074] It should be noted that, in another embodiment, the electronic device not only includes a camera, but also may include a third posture sensor 73. In this case, the function, structure and position of the third posture sensor 73 in the electronic device are the same as those of the third posture sensor 73 in the above embodiment, and only one needs to be set.

[0075] It can be understood that the above-mentioned paired drive motors 60 and attitude sensors 70 can work together to realize the automatic stabilization function of the stabilization device 100 of the present application, and the three pairs of drive motors 60 and attitude sensors 70 can ensure the stability of the camera's attitude in three dimensions. In addition, under the premise of ensuring the stability of the attitude, the paired drive motors 60 and attitude sensors 70 may also control the movement of the camera in the direction of the corresponding rotational freedom at a preset angle and speed, so that the camera can automatically focus and shoot.

[0076] Furthermore, two or three pairs of different driving motors 60 and posture sensors 70 cooperate with each other to control the camera to move along a preset trajectory, thereby enriching the shooting effect of the camera equipment.

[0077] In one embodiment, the drive motor 60 of the present application also includes a fourth drive motor (not shown in the figure). Based on the third posture sensor 73 being fixed to the connecting seat 10, the fourth drive motor can be fixed to the outer ring 30. The fourth drive motor is electrically connected to the third posture sensor 73, that is, the detection signal of the third posture sensor 73 can be directly transmitted to the fourth drive motor via the connecting seat 10 and the circumferential connection unit 40. After receiving the detection signal of the third posture sensor 73, the fourth drive motor can control the relative angle between the inner ring 20 and the outer ring 30. Similarly, it can also keep the posture of the connecting seat 10 relatively stable in the direction of the rotational freedom of the inner ring 20 relative to the outer ring 30. At the same time, the setting of the controller can be omitted, which can simplify the structure of the camera equipment of the present application.

[0078] It should be noted that, in the above-mentioned embodiment, the third drive motor 63 or the fourth drive motor is fixed to the outer ring 30 only as an exemplary introduction. In another embodiment, the third drive motor 63 or the fourth drive motor can also be fixed to the inner ring 20 and connected to the outer ring 30 for driving the outer ring 30 to rotate relative to the inner ring 20. The third attitude sensor 73 is fixed to the connecting seat 10. At this time, the third attitude sensor 73 can be electrically connected to the third drive motor 63 or the fourth drive motor through the connection mode of the transmission line 11, that is, the detection signal of the third attitude sensor 73 can be directly transmitted to the third drive motor 63 or the fourth drive motor via the connecting seat 10 and the circumferential connection unit 40. After receiving the detection signal of the third attitude sensor 73, the third drive motor 63 or the fourth drive motor can also control the relative angle between the inner ring 20 and the outer ring 30.

[0079] Please see Figures 1 to 7 ,in Figure 5 This is a partial structural schematic diagram of a circumferential connection unit 40 provided in an embodiment of the present application; Figure 6 for Figure 1 A schematic diagram of the cross-sectional structure of the middle stabilizing device 100 along AA; Figure 7 for Figure 6 A partial enlarged view of point C in the middle.

[0080] like Figures 1 to 7As shown, in one embodiment, the inner ring 41 of the circumferential connection unit 40 of the present application includes an inner conductive arc 411, and the outer ring 42 includes an outer conductive arc 421. The number of the inner conductive arc 411 and the outer conductive arc 421 are both multiple. The multiple inner conductive arcs 411 are arranged at intervals along the axial direction of the inner ring 20, and the multiple outer conductive arcs 421 are also arranged at intervals along the axial direction of the inner ring 20. Each inner conductive arc 411 is connected to the transmission line 11 of the connecting seat 10, and each outer conductive arc 421 is connected to the controller. And each inner conductive arc 411 is connected to an outer conductive arc 421 to form multiple signal transmission lines 11. The detection signal of the posture sensor 70 is transmitted to the controller via multiple signal transmission lines 11. The present application uses multiple inner conductive arcs 411 and outer conductive arcs 421 to cooperate with each other to realize the electrical connection function of multiple signals between the inner ring 41 and the outer ring 42. In addition, by arranging the plurality of inner conductive arcs 411 and the plurality of outer conductive arcs 421 in an axial direction of the inner ring 20 at intervals, a short circuit caused by contact and conduction between adjacent signal transmission paths can be avoided.

[0081] Furthermore, the inner conductive arc 411 has an arc of 360 degrees, that is, the inner conductive arc 411 is in a circular ring shape, the outer conductive arc 421 has an arc of 30 degrees, the inner conductive arc 411 is fixed to the outer circumference of the inner ring 20, and the outer conductive arc 421 is fixed to the inner circumference of the outer ring 30. The inner conductive arc 411 is in contact with the outer conductive arc 421, or it can be understood that the inner conductive arc 411 is tangent to the outer conductive arc 421. It can be understood that since the curvature of the inner conductive arc 411 is 360 degrees, when the inner conductive arc 411 rotates to any angle around the first axis 001 with the inner ring 20 relative to the outer ring 30, the outer conductive arc 421 fixed to the outer ring 30 can scrape the outer circumferential surface of the inner conductive arc 411, that is, it can contact the inner conductive arc 411 and be electrically conductive, thereby ensuring the reliability of the electrical connection between the inner ring 41 and the outer ring 42, and ensuring that the detection signal of the posture sensor 70 can be stably transmitted to the controller via the circumferential connection unit 40.

[0082] It should be noted that the inner conductive arc 411 and the curvature of the inner conductive arc 411 in the above embodiment are only introduced as examples, and do not represent the curvature of the inner conductive arc 411 and the outer conductive arc 421 in other embodiments of the present application. That is, the curvature of the inner conductive arc 411 and the outer conductive arc 421 can be adaptively adjusted according to the actual application scenario, as long as it can be ensured that when the inner conductive arc 411 rotates to any angle around the first axis 001 with the inner ring 20 relative to the outer ring 30, the inner conductive arc 411 and the outer conductive arc 421 can be in contact and conductive, that is, as long as the sum of the curvatures of the outer conductive arc 421 and the inner conductive arc 411 is greater than 360 degrees. For example, in another embodiment, the curvature of the inner conductive arc 411 can be 180 degrees, and the curvature of the outer conductive arc 421 can be 181 degrees, which can also achieve the same effect as in the above embodiment.

[0083] In one embodiment, one of the inner ring 41 and the outer ring 42 is constructed as an annular PCB board, and a plurality of conductive arcs are printed on the surface of the annular PCB board, and the other is constructed as a plurality of circumferentially distributed contacts or circumferentially distributed short arc structures. Further, the contacts or short arc structures can be in the form of brushes. Each conductive arc is in contact with at least one contact or one short arc structure to achieve the electrical connection function between the inner ring 41 and the outer ring 42. Exemplarily, when the outer ring 42 is set as an annular PCB board, a plurality of outer conductive arcs 421 are printed on its surface close to the inner ring 41, and at this time, the plurality of inner conductive arcs 411 of the inner ring 41 are configured as a plurality of circumferentially distributed contacts or short arc structures, and each outer conductive arc 421 contacts with a contact or short arc structure to achieve electrical connection. Conversely, when the inner ring 41 is set as an annular PCB board, the inner conductive arc 411 of the outer ring 42 is configured as a contact or a short arc structure.

[0084] In one embodiment, the outer circumference of the inner ring 20 is provided with a first groove 21, and the inner circumference of the outer ring 30 is provided with a second groove 31. The inner ring 41 is received in the first groove 21, and the outer ring 42 is received in the second groove 31. It can be understood that the inner ring 20 and the outer ring 30 generally have mechanical strength. The first groove 21 and the second groove 31 are respectively provided on the inner ring 20 and the outer ring 30 to receive and fix the inner ring 41 and the outer ring 42, respectively, so as to protect the inner ring 41 and the outer ring 42 from environmental conditions and physical damage, and also prevent the inner ring 41 or the outer ring 42 from sliding when the inner ring 20 rotates relative to the outer ring 30, resulting in poor contact between the inner ring 41 and the outer ring 42 or circuit breakage and other undesirable phenomena. In addition, the provision of the first groove 21 and the second groove 31 can also reduce the radial gap between the inner ring 20 and the outer ring 30, which is beneficial to the volume control of the stabilizing device 100.

[0085] Further, the first groove 21 includes a plurality of first sub-grooves 211, and the second groove 31 includes a plurality of second sub-grooves 311. The number of the first sub-grooves 211 and the second sub-grooves 311 are both multiple. The plurality of first sub-grooves 211 are arranged at intervals along the axial direction of the inner ring 20, and the plurality of second sub-grooves 311 are also arranged at intervals along the axial direction of the inner ring 20. Each first sub-groove 211 is arranged at a position corresponding to a second sub-groove 311. An inner conductive arc 411 is fixedly accommodated in each first sub-groove 211, and an outer conductive arc 421 is fixedly accommodated in each second sub-groove 311. It can be understood that each first sub-groove 211 accommodates an inner conductive arc 411, and each second sub-groove 311 accommodates an outer conductive arc 421, which can avoid conduction between adjacent inner conductive arcs 411 or adjacent outer conductive arcs 421, that is, conduction between adjacent transmission lines 11 can be avoided, and interference between adjacent signal transmission lines 11 can be avoided, thereby ensuring the reliability of signal transmission.

[0086] It should be noted that, in the above-mentioned embodiment, the number of inner conductive arcs 411 in each first sub-slot 211 and the number of outer conductive arcs 421 in each second sub-slot 311 are only introduced as examples. For example, in some other embodiments, multiple inner conductive arcs 411 can be arranged in the same first sub-slot 211 to form a transmission line 11, which can also ensure stable signal transmission. Similarly, multiple outer conductive arcs 421 can also be arranged in the same second sub-slot 311.

[0087] In one embodiment, a portion of the transmission line 11 is accommodated in the seat body 12 of the connection seat 10, one end of the transmission line 11 is exposed toward the inner ring 20 and is connected to the inner ring 41 of the circumferential connection unit 40, and the other end is exposed toward the electronic device and is connected to the electronic device. It can be understood that based on the fact that the electronic device is fixed to the connection seat 10, and the connection seat 10 is fixed to the inner ring 20, accommodating a portion of the transmission line 11 in the seat body 12 of the connection seat 10 can prevent the transmission line 11 from being exposed and possibly being bumped or damaged. Conducting the opposite ends of the transmission line 11 to the electronic device and the inner ring 41 of the circumferential connection unit 40, that is, setting the transmission line 11 to pass through the seat body 12 of the connection seat 10 and connect and conduct the electronic device and the circumferential connection unit 40, can shorten the actual length of the required transmission line 11, improve the transmission speed of the electrical signal, and optimize the spatial layout of the stabilization device 100.

[0088] In one embodiment, the end of the transmission line 11 close to the electronic device includes a connection port 111, and the connection port 111 is used to plug with the connection terminal of the electronic device to conduct the electronic device. It can be understood that the connection port 111 is provided at the end of the transmission line 11 to plug with the electronic device, so as to facilitate the removal or replacement of the electronic device and improve the compatibility of the stabilizing device 100.

[0089] In one embodiment, the swing arm 52 is a hollow skeleton structure, and the transmission line 11 between the outer ring 42, the third drive motor 63, the first drive motor 61, the first posture sensor 71 and other components and the controller can be accommodated inside the skeleton of the swing arm 52, thereby improving the appearance of the stabilizing device 100 of the present application.

[0090] In one embodiment, the electronic device of the present application includes a camera and a posture sensor 70. When the external device is configured as a battery or a power supply, the battery or the power supply can transmit the power signal to the camera and the posture sensor 70 through one or more transmission lines 11 formed by the circumferential connection unit 40 and the transmission line 11, so as to provide power to the camera and the posture sensor 70; when the external device is configured as a controller, the controller can transmit control signals to the camera and the posture sensor 70 respectively through the multiple transmission lines 11 formed by the circumferential connection unit 40 and the transmission line 11, so as to control the operation of the camera and the posture sensor 70 respectively; when the external device is configured as a receiver, the receiver can receive the image signal or video signal provided by the camera and the detection signal of the posture sensor 70 respectively through the multiple transmission lines 11 formed by the circumferential connection unit 40 and the transmission line 11.
