Description

Technical Field

[0001] This utility model relates to a gimbal, and more particularly to an automatic tracking gimbal with a built-in camera and image transmission. Background Technology

[0002] A three-axis gimbal is a mechanical device used to stabilize photographic equipment. It works in conjunction with three freely rotating axes—roll, pitch, and yaw—to counteract vibrations during movement. The roll axis controls left and right tilt, the pitch axis adjusts vertical angle, and the yaw axis adjusts horizontal rotation. Together, these three axes ensure smooth and stable footage. Its built-in motors and sensors automatically detect and compensate for shake, making it widely used in handheld stabilizers, especially in dynamic scenes where it significantly improves video stability.

[0003] As an extension, a three-axis gimbal can also use the roll, pitch, and yaw axes in combination to track the subject. Its tracking principle requires controlling the three-axis movement in conjunction with image information. However, the gimbal itself lacks image capture capability. A conventional solution is to establish communication between the camera and the gimbal, allowing the camera to transmit real-time images. However, due to device compatibility issues, this approach is difficult to implement widely and has significant limitations in hardware adaptation.

[0004] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0005] This invention overcomes the shortcomings of the above-mentioned technologies and provides an automatic tracking gimbal with a built-in camera and image transmission.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic tracking gimbal with a built-in camera and image transmission includes a handheld unit 1. A first motor 2 is mounted on the top of the handheld unit 1, and a yaw rotation arm 3 is driven and connected to the first motor 2. A second motor 4 is mounted on the end of the yaw rotation arm 3 away from the first motor 2. The second motor 4 drives and connects to a roll rotation arm 5. A third motor 6 is mounted on the end of the roll rotation arm 5 away from the second motor 4. The third motor 6 drives and connects to a pitch rotation arm 7. The end of the pitch rotation arm 7 away from the third motor 6 is used for attaching a camera. A tracking camera 8 is mounted on the front and / or rear sides of the pitch rotation arm 7 for acquiring the shooting direction of the camera. A touch screen display 9 is mounted on the handheld unit 1. The touch screen display 9 communicates with the tracking camera 8 via a wired or wireless connection so that the image acquired by the tracking camera 8 can be displayed on the touch screen display 9 for the user to select a tracking object.

[0008] Preferably, the tracking camera 8 located on the front side shoots forward when the pitch rotation arm 7 is in a horizontal orientation, and the tracking camera 8 located on the rear side shoots backward when the pitch rotation arm 7 is in a horizontal orientation.

[0009] Preferably, each tracking camera 8 is provided with an indicator light 10 to indicate the tracking status.

[0010] Preferably, the upper limit of the tilt arm 7, which is away from the third motor 6, is rotatably connected to an elastic clip 12 for holding the camera device. The elastic clip 12 can rotate 90° relative to the tilt arm 7 to facilitate switching between horizontal and vertical shooting modes. The rotation axis of the elastic clip 12 is perpendicular to the rotation axis of the third motor 6. After the camera device is fixed on the elastic clip 12, its camera shooting direction is parallel to the shooting direction of the tracking camera 8.

[0011] Preferably, the elastic clamp 12 includes a clamping body 121 that is rotatably connected to the pitch rotating arm 7. The clamping body 121 has clamping arms 122 on both the left and right sides. The clamping arms 122 can move in the left and right directions relative to the clamping body 121 and always have a tendency to move towards the clamping body 121. A clamping space 123 for clamping photographic equipment is formed between the two clamping arms 122. The end of the clamping arm 122 away from the clamping body 121 is provided with an adsorption magnet 124 for adsorbing external accessories.

[0012] Preferably, each clamping arm 122 is provided with at least two adsorption magnets 124, and the end of the clamping arm 122 away from the clamping body 121 is also provided with a communication contact 125. The communication contact 125 is used to make electrical communication with external accessories so that the external accessories can exchange data with the gimbal.

[0013] Preferably, the second motor 4 and the roll rotating arm 5 are connected by a leveling component 13, which is used to adjust the left and right relative positions of the second motor 4 and the roll rotating arm 5 in order to adapt to the center of gravity position of different photography equipment.

[0014] Preferably, the leveling assembly 13 includes a tensioning seat 131 that is directly driven to rotate by the second motor 4 and connected to the second motor 4. The tensioning seat 131 has a limiting protrusion 132 on one side and a limiting pressure block 134 fixed on the other side by a tension adjusting screw 133. A limiting guide groove 135 is formed between the limiting protrusion 132 and the limiting pressure block 134 for one end of the rolling rotating arm 5 to pass through. The tension adjusting screw 133 is used to adjust the height of the limiting pressure block 134 so as to press / release the rolling rotating arm 5.

[0025] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0026] like Figures 1 to 5As shown, an automatic tracking gimbal with a built-in camera and image transmission includes a handheld unit 1. A first motor 2 is mounted on the top of the handheld unit 1, and a yaw rotation arm 3 is driven and connected to the first motor 2. A second motor 4 is mounted on the end of the yaw rotation arm 3 away from the first motor 2. The second motor 4 drives and connects to a roll rotation arm 5. A third motor 6 is mounted on the end of the roll rotation arm 5 away from the second motor 4. The third motor 6 drives and connects to a pitch rotation arm 7. The end of the pitch rotation arm 7 away from the third motor 6 is used for connecting a photography device. A tracking camera 8 is mounted on the front and / or rear sides of the pitch rotation arm 7 for acquiring the shooting direction of the photography device. A touch screen display 9 is mounted on the handheld unit 1. The touch screen display 9 communicates with the tracking camera 8 via a wired or wireless connection so that the image acquired by the tracking camera 8 can be displayed on the touch screen display 9 for the user to select the tracking object.

[0027] This automatic tracking gimbal includes a handheld unit 1, on which are sequentially connected a first motor 2, a yaw rotation arm 3, a second motor 4, a roll rotation arm 5, a third motor 6, and a pitch rotation arm 7. The end of the pitch rotation arm 7 furthest from the third motor 6 is used to connect external photographic equipment. By using the three motors to drive the corresponding rotation arms based on sensor information, conventional image stabilization can be achieved. In addition, this automatic tracking gimbal also has a tracking camera 8 on the pitch rotation arm 7. By integrating the tracking camera 8 onto the pitch rotation arm 7, the gimbal does not need to rely on image transmission from a photographic device, and can independently achieve tracking functionality based on the image information acquired by the tracking camera 8. The tracking camera 8 can be placed only on the front or rear side of the pitch rotation arm 7 to track objects in only one direction, or it can be deployed on both the front and rear sides of the pitch rotation arm 7, allowing users to easily select different tracking objects in different directions. Furthermore, the handheld part 1 of the automatic tracking gimbal in this case is also equipped with a touch screen 9. The tracking camera 8 can transmit the captured image information to the touch screen 9 through wired or wireless communication. Users can directly see the real-time image captured by the tracking camera 8 on the touch screen 9 and intuitively select the tracking object through the touch screen 9.

[0028] As described above, the automatic tracking gimbal in this case integrates a tracking camera 8 on the pitch and rotation arm 7 and a touch screen 9 on the handheld unit 1. By integrating the tracking camera 8 and the touch screen 9, the gimbal does not need to rely on external photography equipment for image transmission, solving various communication obstacles caused by device compatibility in traditional solutions. This achieves self-sufficient gimbal tracking functionality, improving versatility and ease of operation. Users can also directly select the tracking target on the touch screen 9, greatly simplifying the operation process.

[0029] like Figures 1 to 3 As shown, preferably, the tracking camera 8 located on the front side shoots forward when the pitch rotation arm 7 is in a horizontal position, and the tracking camera 8 located on the rear side shoots backward when the pitch rotation arm 7 is in a horizontal position. In this way, after the pitch rotation arm 7 is in a stable state, it can be ensured that the image captured by the tracking camera 8 can cover the front and / or the rear. This can ensure that the object tracked by the tracking camera 8 can basically overlap with the object being photographed by the camera, so that the tracking effect can meet the user's shooting expectations.

[0030] like Figures 1 to 3 As shown, preferably, each tracking camera 8 is provided with an indicator light 10 to indicate the tracking status. In this way, the real-time feedback of the tracking status through the indicator light 10 allows the user and the subject to more intuitively judge whether the gimbal has locked onto the tracking target and entered the tracking state. This avoids the failure to detect misoperation or tracking failure in time, resulting in unusable footage. This setting of the indicator light 10 can effectively improve the efficiency of human-computer interaction and user experience.

[0031] Specifically, when one of the tracking cameras 8 successfully acquires the target and the gimbal enters the tracking state, the indicator light 10 corresponding to that tracking camera 8 will remain solid green.

[0032] Furthermore, if there are multiple tracking cameras 8, the user can select the tracking object from the image captured by any one of the tracking cameras 8.

[0033] like Figures 1 to 3 As shown, preferably, the upper limit of the tilt rotation arm 7 away from the third motor 6 is rotatably connected to an elastic clip 12 for holding the camera equipment. The elastic clip 12 can rotate 90° relative to the tilt rotation arm 7 to facilitate switching between horizontal and vertical shooting modes. The rotation axis of the elastic clip 12 is perpendicular to the rotation axis of the third motor 6. After the camera equipment is fixed on the elastic clip 12, its camera shooting direction is parallel to the shooting direction of the tracking camera 8.

[0034] As described above, the automatic tracking gimbal in this case is equipped with a flexible clamp 12 on the pitch rotation arm 7 for holding the camera equipment. This allows for quick and convenient fixation of the camera equipment onto the automatic tracking gimbal. The flexible clamp 12 can rotate 90° relative to the pitch rotation arm 7, facilitating user switching between horizontal and vertical shooting modes. Furthermore, after the camera equipment is clamped onto the flexible clamp 12, its camera's shooting direction is parallel to the shooting direction of the tracking camera 8. Simultaneously, the rotation axis of the flexible clamp 12 is perpendicular to the rotation axis of the third motor 6. This ensures that the camera equipment will not deflect in either horizontal or vertical shooting modes and will maintain the same shooting angle as the tracking camera 8, effectively preventing tracking deviation.

[0035] like Figures 1 to 3 As shown, preferably, the elastic clamp 12 includes a clamp body 121 that is rotatably connected to the pitch rotating arm 7. The clamp body 121 has clamp arms 122 on both the left and right sides. The clamp arms 122 can move in the left and right directions relative to the clamp body 121 and always have a tendency to move towards the clamp body 121. A clamping space 123 for clamping photographic equipment is formed between the two clamp arms 122. The end of the clamp arm 122 away from the clamp body 121 is provided with an adsorption magnet 124 for adsorbing external accessories.

[0036] As described above, the size of the clamping space 123 in the elastic clamp 12 can be changed by pulling open the clamping arms 122 on both sides, thus facilitating the insertion of photographic equipment of different sizes. After the external force is removed, the clamping arms 122 on both sides will automatically move towards the clamping body 121 to clamp the photographic equipment in the clamping space 123. In addition, the automatic tracking gimbal in this case is also equipped with magnetic magnets 124 on the clamping arms 122, which can conveniently and quickly fix external accessories, such as fill lights, thereby further expanding the functionality of the gimbal.

[0037] like Figures 1 to 3 As shown, preferably, each clamping arm 122 is provided with at least two adsorption magnets 124, and the end of the clamping arm 122 away from the clamping body 121 is also provided with a communication contact 125. The communication contact 125 is used to make electrical communication with external accessories so that the external accessories can exchange data with the gimbal.

[0038] As described above, each clamping arm 122 is provided with at least two adsorption magnets 124, and the clamping arm 122 is also provided with a communication contact 125 on the outer side. The two adsorption magnets 124 can effectively position and adsorb external accessories. The positioning and adsorption can also allow some external accessories with data exchange functions to accurately contact the communication contact 125, thereby realizing data exchange with the gimbal and further expanding the function of the gimbal.

[0039] like Figures 1 to 5 As shown, preferably, the second motor 4 and the roll rotating arm 5 are connected by a leveling component 13. The leveling component 13 is used to adjust the relative left and right positions of the second motor 4 and the roll rotating arm 5 to adapt to the center of gravity position of different photography equipment. In this way, by adjusting the relative position of the roll rotating arm 5 and the second motor 4 through the leveling component 13, the weight distribution of different photography equipment can be adapted to ensure that the center of gravity of the gimbal is always balanced, avoiding motor overload or image shaking caused by center of gravity shift, thereby improving the stability of the gimbal and the life of the equipment.

[0040] like Figures 1 to 5As shown, preferably, the leveling assembly 13 includes a tensioning seat 131 that is directly driven to rotate by the second motor 4 and connected to the second motor 4. The tensioning seat 131 has a limiting protrusion 132 on one side and a limiting pressure block 134 fixed on the other side by a tension adjusting screw 133. A limiting guide groove 135 is formed between the limiting protrusion 132 and the limiting pressure block 134 for one end of the rolling rotating arm 5 to pass through. The tension adjusting screw 133 is used to adjust the height of the limiting pressure block 134 so as to press / release the rolling rotating arm 5.

[0041] As described above, the leveling assembly 13 of this invention forms a limiting guide groove 135 in the tensioning seat 131 through the limiting protrusion 132 and the limiting pressure block 134. One end of the rolling rotating arm 5 can pass into the limiting guide groove 135 and move left and right therein, thereby changing the relative position of the rolling rotating arm 5 and the second motor 4. When the rolling rotating arm 5 moves to the appropriate position, the limiting protrusion 132 can be locked by the tension adjusting screw 133 to press the rolling rotating arm 5 into the limiting guide groove 135, thereby fixing the relative position of the rolling rotating arm 5 and the second motor 4. When readjustment is needed, the position of the rolling rotating arm 5 can be changed again by loosening the tension adjusting screw 133.

[0042] like Figures 1 to 5 As shown, preferably, the second motor 4 and the tension seat 131 are both provided with a cable passage hole 136 in the center. The bottom of the part of the roll rotating arm 5 that passes through the limiting guide groove 135 is provided with a cable passage groove 137 extending in the same direction as the limiting guide groove 135. The center line of the cable passage groove 137 intersects with the center axis of the cable passage hole 136. In this way, the cable inside the gimbal can pass through the cable passage hole 136 and the cable passage groove 137 to pass through the leveling component 13. By providing a cable passage groove 137 extending in the same direction as the limiting guide groove 135 at the bottom of the roll rotating arm 5, the cable inside the gimbal can be effectively prevented from being pulled when the roll rotating arm 5 moves in the limiting guide groove 135.

[0043] like Figure 3 As shown, preferably, a telescopic rod 14 is also provided between the top of the handheld part 1 and the first motor 2. In this way, the height of the gimbal can be changed by the telescopic rod 14, thereby expanding the height adjustment range of the gimbal and making the gimbal better adaptable to different shooting angles.

[0044] like Figure 2 As shown, preferably, the bottom of the handheld part 1 is also provided with a threaded hole 15 for connecting external accessories. In this way, the gimbal can be connected to more external accessories, such as tripods, through the threaded hole 15, thereby further enhancing the applicability of the gimbal to different practical scenarios.

[0045] As stated above, this case protects an automatic tracking gimbal with a built-in camera and image transmission. All technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
