[0030] The gimbal device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0031] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the gimbal device provided in the embodiments of this application. Figure 2 This is a schematic cross-sectional view of the gimbal device provided in an embodiment of this application. Figure 1 and Figure 2 As shown, the gimbal device includes:
[0032] The camera module 10, screen 20, main body 30 and connecting arm assembly 40 are included. One end of the connecting arm assembly 40 is connected to the main body 30 and the other end of the connecting arm assembly 40 is connected to the camera module 10. The main body 30 includes a housing 31 and a rotating device 32. The screen 20 is rotatably connected to the housing 31 through the rotating device 32.
[0033] The outer casing 31 has an arc-shaped groove 311 on the side facing the screen 20. One end of the rotating device 32 is disposed in the arc-shaped groove 311, and the other end of the rotating device 32 is connected to the screen 20.
[0034] When the rotating device 32 moves in the arc-shaped slide 311, the rotating device 32 can drive the screen 20 to rotate relative to the main body 30.
[0035] In this application embodiment, the gimbal device can refer to a camera device with a gimbal unit, such as a gimbal camera.
[0036] like Figure 1As shown, the gimbal device in this embodiment includes a camera module 10, a screen 20, a main body 30, and a connecting arm assembly 40. The camera module 10 is connected to the main body 30 via the connecting arm assembly 40. The main body 30 includes a housing 31 and a rotating device 32. The screen 20 is mounted on the housing 31. Specifically, the screen 20 is rotatably connected to the housing 31 via the rotating device 32, allowing the screen 20 to rotate relative to the housing 31, thus realizing the screen rotation function of the gimbal device. For example, the top structure of the gimbal camera is the camera module 10, and the screen 20 is mounted on the housing 31 of the main body 30 to display the images captured or photographed by the camera module 10. The main body 30 can support the camera module 10 and rotate it in different directions via the connecting arm assembly 40, allowing the camera module 10 to capture images from multiple angles. The screen 20 is rotatably connected to the housing 31, allowing the screen 20 to rotate relative to the housing 31 and be in different states, such as a horizontal or vertical screen state.
[0037] Specifically, such as Figure 2 As shown, in order to achieve relative rotation between the screen 20 and the outer casing 31, this embodiment of the application designs a rotating structure between the screen 20 and the outer casing 31. An arc-shaped groove 311 is provided on the side of the outer casing 31 facing the screen 20. One end of the rotating device 32 is disposed in the arc-shaped groove 311, and the other end is connected to the screen 20. Thus, when the screen 20 is rotated, the rotating device 32 can slide along the arc-shaped groove 311 in an arc shape. In other words, when the rotating device 32 moves in the arc-shaped groove 311, the rotating device 32 can drive the screen 20 to rotate relative to the main body 30, thereby realizing the screen rotation function of the gimbal device.
[0038] Among them, the arc-shaped slide 311 is an arc-shaped slide structure, which can be a curved slide, a circular arc slide, or a petal-shaped slide formed by splicing multiple circular arcs. The arc-shaped slide 311 can be a closed track or just a section of track. When the arc-shaped slide 311 is a closed track, it can realize the 360-degree rotation of the screen 20 relative to the main body 30. When the arc-shaped slide 311 is an unclosed arc track, it can realize the rotation of the screen 20 relative to the main body 30 within a certain angle range.
[0039] Optionally, the outer casing 31 has a through hole 312, which is disposed on the first side of the arc-shaped groove 311. The screen 20 also has a rotating shaft 21 on the side facing the main body 30. One end of the rotating shaft 21 is connected to the screen 20, and the other end of the rotating shaft 21 passes through the through hole 312 and is disposed inside the outer casing 31. When the rotating device 32 can drive the screen 20 to rotate, the rotating shaft 21 rotates in the through hole 312. The first side is the side pointed to by the concave direction of the concave part of the arc-shaped groove 311.
[0040] In some embodiments, the screen 20 and the housing 31 can also be rotatably connected via a pivot, specifically, as shown in... Figure 2 and Figure 4a As shown, a pivot 21 is provided on the back of the screen 20. The pivot 21 extends and protrudes towards one side of the outer casing 31. A through hole 312 is provided at the corresponding position on the side of the outer casing 31 facing the screen 20. The through hole 312 can also be called a pivot groove 312, which is used to accommodate the pivot 21. That is, one end of the pivot 21 is installed in the pivot groove 312. It should be noted that the positional relationship between the through hole 312 and the arc-shaped slide groove 311 on the outer casing 31 can be that the through hole 312 is located on the side pointed to by the recessed direction of the recessed part on the arc-shaped slide groove 311. That is, the arc-shaped slide groove 311 can be provided with a recessed part, and the pivot 21 is close to the recessed part. This is beneficial for the rotating device 32 to realize the rotation limit function through the recessed part on the arc-shaped slide groove 311.
[0041] In this embodiment, when the rotating device 32 drives the screen 20 to rotate in a certain direction, the rotating shaft 21 will rotate in the same opposite direction in the through hole 312. That is, the rotating device 32 and the rotating shaft 21 can cooperate with each other to achieve synchronous linkage rotation. Through this structure, the rotational connection between the screen 20 and the outer shell 31 can be smoother and more reliable.
[0042] It should be noted that in some embodiments, in order to ensure that the screen 20 is securely mounted on the housing 31 without detaching, the end of the pivot 21 extending into the housing 31 can be designed to have a bottom disc structure. The cross-sectional area of this structure is larger than the cross-sectional area of the central pivot. The pivot groove 312 on one side of the housing 31 is adapted to the structure of the pivot 21, so that the pivot 21 can be engaged in the pivot groove 312 without sliding out.
[0043] Optionally, the rotating device 32 and the rotating shaft 21 are connected by an elastic element 323, that is, one end of the elastic element 323 is connected to the rotating device 32 and the other end is connected to the rotating shaft 21, and the elastic element 323 is kept in a certain tension state. In this way, not only can the linkage rotation between the rotating device 32 and the rotating shaft 21 be better guaranteed by the elastic element 323, but the tension force of the elastic element 323 on the rotating device 32 can also ensure that the rotating device 32 slides stably and reliably in the arc-shaped slide groove 311.
[0044] Optionally, the arc-shaped slide 311 is a closed arc-shaped slide connected end to end, and the through hole 312 is set at the structural center of the arc-shaped slide 311. When the rotating device 32 slides in the arc-shaped slide 311, the rotating device 32 can drive the screen 20 to rotate relative to the main body 30.
[0045] In some embodiments, the arc-shaped groove 311 can be designed as a closed arc-shaped groove with its ends connected, and the through hole 312 for mounting the rotating shaft 21 is located at the center of the arc-shaped structure enclosed by the arc-shaped groove 311. For example, the arc-shaped groove 311 is centrally symmetrical with respect to the through hole 312. When the rotating device 32 slides in the arc-shaped groove 311, the rotating device 32 can drive the screen 20 to rotate relative to the main body 30. In particular, when the rotating device 32 slides one revolution in the arc-shaped groove 311, it can drive the screen 20 to rotate one revolution relative to the main body 30.
[0046] For example, such as Figure 6 and Figure 8 As shown, the through hole 312 can be located in the middle of the arc-shaped groove 311, ensuring that the distance from each point in the arc-shaped groove 311 to the through hole 312 is relatively consistent, which is beneficial to ensuring the structural stability when rotating the screen. In addition, when the rotating device 32 is connected to the rotating shaft 21 by an elastic element 323, this design structure allows the rotating device 32 to move under the relatively uniform tension of the elastic element 323, which also ensures that the user has a better operating experience when rotating the screen 20.
[0047] In some embodiments, the arc-shaped groove 311 may include at least two spliced arc-shaped tracks, that is, the arc-shaped groove 311 is formed by splicing at least two arc-shaped tracks. For example, as shown in the figure... Figure 3 As shown, the arc-shaped groove 311 is a petal-shaped track formed by splicing four arc-shaped tracks. It should be noted that in some embodiments of this application, the rotating device 32 and the rotating shaft 21 are connected by an elastic member 323. Thus, the rotating device 32 can be tightened by the pulling force of the elastic member 323, so that the rotating device 32 can be relatively stationary in a specific position or any position in the arc-shaped groove 311 without external force rotating the screen 20. This allows the screen 20 to be in a specific rotation angle relative to the outer shell 31, such as 0 degrees, 90 degrees, etc. The specific design can be based on actual needs, and the embodiments of this application are not specifically limited.
[0048] Thus, the embodiments of this application can realize the rotation of the screen 20 relative to the outer shell 31 and can be fixed in a specific state, realizing the control of different rotation angles of the screen 20. Based on this structure, it is possible to further design the gimbal device to be turned on, turned off or other specific functions based on the specific rotation angle of the screen. Moreover, this structure has the advantage of low cost compared with the existing structural solutions that use magnets and motors.
[0049] Optionally, an angle sensor 50 is also installed at the bottom of the pivot 21. The angle sensor 50 is used to detect the rotation angle of the screen 20 relative to the housing 31. When the angle sensor 50 detects a target rotation angle of the screen 20 relative to the housing 31, the gimbal device is triggered to power on or off.
[0050] In some embodiments, such as Figure 2 , Figure 4a and Figure 4b As shown, an angle sensor 50 can be installed at the bottom of the hinge 21 to detect the rotation angle of the screen 20 relative to the housing 31. For example, as shown... Figure 5 As shown, the screen 20 is in portrait mode by default. In the default state, the angle sensor 50 does not detect the rotation of the screen 20, that is, the angle detection value is 0°. When the screen 20 is rotated, such as when the user manually rotates the screen 20 so that the screen 20 rotates relative to the outer casing 31, the angle sensor 50 detects the rotation. The angle detection value at this time is determined by the specific angle of rotation of the screen 20 relative to the outer casing 31.
[0051] To enable the gimbal device to automatically power on or off when the screen rotates to a specific angle, in this embodiment, the angle sensor 50 can transmit the detected rotation angle value to the main control chip (not shown in the figure) of the gimbal device. When the main control chip reads a specific rotation angle value, it controls the camera module 10 to turn on and the screen 20 to power on and display. And / or, when the main control chip reads another specific rotation angle value, it controls the camera module 10 to turn off and the screen 20 to power off. The target angle may include at least one of 0°, 90°, 180° and 270°, and different target angles can trigger different functions.
[0052] For example, when the screen 20 is rotated to a position of 90° or 270°, the angle sensor 50 can sense that the screen 20 is in a 90° or 270° position, i.e., in landscape mode, thereby triggering the PTZ device to power on; when the screen 20 is rotated to a position of 0° or 180°, the angle sensor 50 can sense that the screen 20 is in a 0° or 180° position, i.e., in portrait mode, thereby triggering the PTZ device to power off.
[0053] This enables the gimbal device to automatically power on or off based on a specific angle of screen rotation, while maintaining a simple structure and low cost.
[0054] Optionally, the arc-shaped groove 311 includes an arc-shaped portion 3111 and a recessed portion 3112 connected to each other. The recessed portion 3112 is recessed toward the rotating shaft 21. When the rotating device 32 is located in the recessed portion 3112, the rotating device 32 is in a limiting fit with the recessed portion 3112.
[0055] As one implementation method, such as Figure 3As shown, the arc-shaped groove 311 includes interconnected arc-shaped portions 3111 and recessed portions 3112. That is, the arc-shaped groove 311 may include multiple arc-shaped portions 3111, with a recessed portion 3112 formed between two connected arc-shaped portions 3111. For example, the arc-shaped groove 311 may have two or more recessed portions 3112. It should be noted that when the arc-shaped groove 311 is a closed annular track composed of at least two circular arc tracks, the number of recessed portions 3112 may be consistent with the number of circular arc tracks. Figure 3 In this embodiment, four arc-shaped tracks form a petal-shaped track with four recesses 3112. The recesses 3112 can cooperate with the rotating device 32 to achieve a rotational limiting function. In some applications, the recesses 3112 can be positioned at specific points on the arc-shaped groove 311 to limit the screen 20 to certain states, such as landscape or portrait orientation. For example, when the rotating device 32 moves to the recesses 3112, the screen 20 is in a landscape or portrait orientation, and the rotating device 32 remains at the recesses 3112 without external force.
[0056] like Figure 6 As shown, the distance between the recessed portion 3112 and the through hole 312 is closer than any point on the arc-shaped portion 3111. The elastic element 323 exerts a pulling force on the rotating device 32. Therefore, when the rotating device 32 is in the middle position of the arc-shaped groove 311, the elastic element 323 has the smallest stretching deformation and the smallest pulling force. When the rotating device 32 rotates clockwise or counterclockwise from the recessed portion 3112, the elastic element 323 will be stretched to become longer. This requires the user to continuously apply a certain torque, i.e., to rotate the screen 20. In other words, when the rotating device 32 moves to the recessed portion 3112, if the external force on the screen 20 disappears or the external force is insufficient, the rotating device 32 will stop at the recessed portion 3112, keeping the screen 20 at the current rotation angle.
[0057] In other words, the rotating mechanism in this embodiment has a certain self-locking force, and it is not easy to rotate in a certain state of the screen (not that it is completely locked), and the user needs to continuously apply torque to achieve this.
[0058] Furthermore, considering that in actual use, users typically only need to rotate the screen 20 to either landscape or portrait mode, the recessed portion 3112 can be designed to be located in the horizontal or vertical direction of the rotating shaft 21, so that when the rotating device 32 moves to the recessed portion 3112, the screen 20 is in either landscape or portrait mode. It should be noted that in some embodiments, multiple recessed portions 3112 can be used to fix the screen 20 in both landscape and portrait modes; in other embodiments, the recessed portion 3112 can be used to fix the screen 20 in one of these modes, while the starting or ending end of the arc-shaped groove 311 limits the movement to fix the screen 20 in the other mode.
[0059] This embodiment enables the rotating mechanism to have a self-locking force, thereby allowing the screen to remain in landscape or portrait mode without external force, preventing the screen from rotating or shaking.
[0060] Furthermore, the arc-shaped groove 311 has at least two recesses 3112, the first recess of the at least two recesses 3112 is located in the first direction of the through hole 312, and the second recess of the at least two recesses 3112 is located in the second direction of the through hole 312, the first direction being perpendicular to the second direction.
[0061] When the rotating device 32 moves to the first recessed portion, the screen 20 is in portrait mode; when the rotating device 32 moves to the second recessed portion, the screen 20 is in landscape mode.
[0062] In some embodiments, the arc-shaped groove 311 has at least two recesses 3112, one recess 3112 for limiting the screen 20 to a portrait orientation, and the other recess 3112 for limiting the screen 20 to a landscape orientation. For example, Figure 6 As shown, the first recess E1 is located in the first direction of the through hole 312, such as the up-down direction, and the second recess E2 is located in the second direction of the through hole 312, such as the left-right direction. When the rotating device 32 moves from the first recess E1 to the second recess E2, the screen 20 is rotated 90° counterclockwise and is in a horizontal state. When the rotating device 32 moves from the second recess E2 to the first recess E1, the screen 20 is rotated 90° clockwise and is in a vertical state.
[0063] This implementation method enables the internal rotating mechanism to automatically generate a certain locking force when the screen is rotated to landscape or portrait mode, preventing screen shaking and improving the user experience.
[0064] Optionally, the arc-shaped groove 311 includes four recesses 3112 and four arc-shaped portions 3111. The four arc-shaped portions are connected to each other to form a closed groove. A recess is formed between every two connected arc-shaped portions. Two of the four recesses are located in a first direction and are symmetrical with respect to the rotation axis 21, while the other two recesses are located in a second direction and are symmetrical with respect to the rotation axis 21. The first direction is perpendicular to the second direction.
[0065] For example, the arc-shaped slide 311 includes four arc-shaped tracks, and the four arc-shaped tracks are spliced to form a closed track; the arc-shaped slide 311 has four recesses 3112, of which two recesses 3112 are located in the first direction and are symmetrical with respect to the rotation axis 21, and the other two recesses are located in the second direction and are symmetrical with respect to the rotation axis 21. When the rotating device 32 moves from the third recess to the fourth recess, the screen 20 rotates 90 degrees. The third recess and the fourth recess are any two adjacent recesses.
[0066] like Figure 8 As shown, the arc-shaped slide 311 includes four arc-shaped tracks, or four arc-shaped portions 3111, which are sequentially spliced together to form a closed petal-shaped track. Correspondingly, the arc-shaped slide 311 has four recesses 3112, two of which are symmetrically located in the vertical direction of the rotating shaft 21, and the other two are symmetrically located in the horizontal direction of the rotating shaft 21. When the rotating device 32 moves from one adjacent recess to another, the screen 20 rotates 90° accordingly. When the rotating device 32 rotates counterclockwise one revolution starting from the first recess of these four recesses, the screen 20 rotates 90°, 180°, 270°, and 360° sequentially.
[0067] It can also be seen that, since the arc-shaped slide 311 in this embodiment is a closed ring track, it can achieve no limitation on the screen rotation angle and rotation direction, that is, the screen 20 can rotate clockwise or counterclockwise, and can rotate 360 degrees.
[0068] Optionally, when the rotating device 32 moves from the first recess along the first arcuate portion to the second recess under the action of an external force, and the external force disappears after the rotating device 32 moves to the first position of the first arcuate portion, the rotating device 32 automatically continues to move along the first arcuate portion to the second recess. The first arcuate portion is the arcuate portion between the first recess and the second recess, and the first position is any position on the first arcuate portion between the midpoint of the first arcuate portion and the second recess.
[0069] like Figure 7As shown, in the default state of screen 20, the rotating device 32 is located in the first recessed part E1. When the user rotates screen 20, screen 20 drives rotating device 32 to move along arc-shaped slide 311. Under the action of external force, rotating device 32 moves from the first recessed part E1 along the first arc-shaped part A1 to the second recessed part E2. When the rotation reaches a certain angle, such as 45°, and rotating device 32 moves to the midpoint of the first arc-shaped part A1, elastic element 323 is stretched to its maximum value. If it continues to rotate slightly to exceed 45°, rotating device 32 moves to the midpoint of the first arc-shaped part A1. Under the combined action of the tension of elastic element 323 and the arc of the first arc-shaped part A1, rotating device 32 will automatically rotate screen 20 to a 90° position, that is, move to the second recessed part E2.
[0070] In other words, when the user manually rotates the screen 20 more than 45°, that is, after the movement distance of the rotating device 32 exceeds half of an arc track, the screen 20 can generate a force to automatically rotate to 90°.
[0071] In this embodiment, the user only needs to rotate the screen a certain amount to trigger the screen to automatically rotate to a specific position, achieving the effect of the screen rotating by its own force, without the user having to continuously rotate to that position, thus providing a more relaxed user experience.
[0072] Optionally, the outer casing 31 is provided with a groove 3114 that matches the shape of the arc-shaped groove 311, and a guide block 3115 with an outer peripheral shape that matches the shape of the arc-shaped groove 311 is provided on the outer casing 31. The guide block 3115 is located in the groove 3114, and the groove 3114 and the guide block 3115 form the arc-shaped groove 311.
[0073] In one implementation, the arc-shaped groove 311 can be achieved by forming a groove 3114 and a guide block 3115 with a matching shape on the housing 31, such as... Figure 6 and Figure 8 As shown, the outer shell 31 has a groove 3114 that matches the shape of the arc-shaped groove 311, such as a petal-shaped groove, and a guide block 3115 with an outer periphery that matches the shape of the groove 3114, such as a petal-shaped guide block, in the middle of the groove 3114. In this way, an arc-shaped groove 311 with a corresponding shape can be formed between the groove 3114 and the guide block 3115, such as a petal-shaped track. In some embodiments, the groove 3114 and the guide block 3115 can be designed and molded as a single piece.
[0074] This implementation method enables the design of an arc-shaped groove with a specific groove shape on the outer casing 31, which serves as the motion track for the rotating device 32.
[0075] Optionally, a slide rail 22 is provided on the side of the screen 20 facing the housing 31. The slide rail 22 extends radially along the rotating shaft 21 and away from the rotating shaft 21. The rotating device 32 includes a roller 321 and an elastic element 323. The roller 321 includes a first disk 3211, a second disk 3212 and a connecting shaft 3213. The two ends of the connecting shaft 3213 are fixedly connected to the first disk 3211 and the second disk 3212, respectively. The first disk 3211 is slidably connected to the slide rail 22, and the second disk 3212 is slidably connected to the arc-shaped groove 311. One end of the elastic element 323 is connected to the connecting shaft 3213, and the other end of the elastic element 323 is connected to the rotating shaft 21. When the roller 321 is located in the arc-shaped portion 3111, the elastic element 323 drives the roller 321 to move to the recessed portion 3112.
[0076] In some embodiments, such as Figure 2 As shown, a slide rail 22 can also be designed on the back of the screen 20. The slide rail 22 can also be called a slot 22. One end of the rotating device 32 is installed in the arc-shaped slide groove 311, and the other end of the rotating device 32 is installed in the slide rail 22. The end of the rotating device 32 installed in the slide rail 22 can slide in the slide rail 22. When rotating the screen 20, one end of the rotating device 32 can slide along the arc-shaped slide groove 311, and the other end can slide in the slide rail 22.
[0077] Specifically, such as Figure 4a , Figure 4b and Figure 12 As shown, the slide rail 22 extends radially along the rotating shaft 21 and in a direction away from the rotating shaft 21. The rotating device 32 includes a roller 321 and an elastic element 323, as shown. Figure 9 and Figure 10 As shown, the roller 321 has a disc base at both ends, namely a first disc 3211 and a second disc 3212. The first disc 3211 and the second disc 3212 are connected by a connecting shaft 3213. The first disc 3211 is slidably connected to the slide rail 22, and the second disc 3212 is slidably connected to the arc-shaped slide groove 311. It should be noted that the diameter of the discs at both ends of the roller 321 is larger than the diameter of the cross section of the connecting shaft 3213. In this way, the roller 321 can be stably and reliably connected to the screen 20 and the outer shell 31 respectively.
[0078] like Figure 4a As shown, one end of the elastic element 323 is connected to the connecting shaft 3213, and the other end is connected to the rotating shaft 21. Even when the roller 321 is located in the arc-shaped portion 3111 and no external force is applied, the elastic element 323 can pull the roller 321 along the arc-shaped portion 3111 until it reaches the recessed portion 3112. This achieves the effect of the screen rotating automatically without requiring the user to continuously rotate the screen 20 to the corresponding position of the recessed portion, thus providing a more convenient user experience.
[0079] Optionally, the arc-shaped slide groove 311 has a toothed surface 3113 on its side wall near the rotating shaft 21. The rotating device 32 also includes a gear 322, which is sleeved on the roller 321 and meshes with the toothed surface 3113. That is, the outer periphery of the guide block 3115 is gear-shaped, and the gear 322 meshes with the guide block 3112.
[0080] In some embodiments, such as Figure 9 As shown, the rotating device 32 includes a roller 321 and a gear 322 nested in the roller 321, as... Figure 2 and Figure 6 As shown, one end of the scroll wheel 321 is nested in the slide rail 22 of the screen 20, and the other end of the scroll wheel 321 is nested in the arc-shaped slide groove 311, as... Figure 8 As shown, the sidewall of the arc-shaped slide 311 near the rotating shaft 21 is designed as a gear-shaped structure, forming a toothed surface 3113. The rotating device 32 is connected to the toothed surface 3113 by gear 322 meshing with it. When the roller 321 moves in the arc-shaped slide 311, the gear 322 and the toothed surface 3113 are always meshed, and the gear 322 rolls along the toothed surface 3113 of the arc-shaped slide 311. In this embodiment, the rotating device can be implemented with a simple roller and gear structure, and due to the meshing of gear 322 and toothed surface 3113, the stability of the relative state between the screen 20 and the outer casing 31 can be better guaranteed, preventing the screen 20 from shaking excessively during rotation.
[0081] Optionally, a groove 3210 is provided on the connecting shaft 3213, and the gear 322 is disposed in the groove 3210.
[0082] like Figure 10 As shown, a portion of the roller 321 located at one end of the arc-shaped groove 311 can be removed to form a groove 3210, making the cylinder diameter at this end smaller than the cylinder diameter at the other end. This groove 3210 structure is used to accommodate the gear 322, wherein the gear 322 has the following structural shape. Figure 11 As shown, it fits precisely onto the end of the roller 321 after the portion has been removed, i.e., it is set in the groove 3210. This structure allows the roller 321 and the gear 322 to be nested together seamlessly, achieving a simple and aesthetically pleasing design.
[0083] Optionally, the elastic element 323 has a first spring coil 3231 and a second spring coil 3232 at its two ends, respectively. The first spring coil 3231 is sleeved on the connecting shaft 3213, and the second spring coil 3232 is sleeved on the rotating shaft 21.
[0084] In some embodiments, the elastic element 323 may be implemented using a spring, such as Figure 8 and Figure 4aAs shown, the elastic element 323 has spring coils at both ends, namely a first spring coil 3231 and a second spring coil 3232. One end of the spring coil, such as the first spring coil 3231, is sleeved on the rotating device 32, specifically on the connecting shaft 3213 of the roller 321. The other end of the spring coil, such as the second spring coil 3232, is sleeved on the rotating shaft 21. The size of the first spring coil 3231 sleeved on the roller 321 is adapted to the diameter of the roller 321, and the size of the second spring coil 3232 sleeved on the rotating shaft 21 is adapted to the diameter of the rotating shaft 21. In this way, it can ensure that the elastic element 323 is firmly connected to the rotating device 32 and the rotating shaft 21, and also ensure that it provides a good pulling force to the rotating device 32.
[0085] The following is combined Figures 12 to 15 The structure of the screen 20, housing 31, and slide rail 22 in the embodiments of this application will be further described as follows:
[0086] The structure of screen 20 is as follows Figure 12 As shown, a rotating shaft 21 is provided on the back, and a slide rail 22, also called a slot 22, is provided next to the rotating shaft 21 to accommodate the rotating device 32. The horizontal and vertical cross-sectional views of the slot 22 are shown in the figures. Figure 13a and Figure 13b As shown, the slot 22 is a long T-shaped slot. The width of the slot 22 can be slightly larger than the diameter of the disc of the roller 321, so that it can basically hold the roller 321 and leave a certain sliding distance.
[0087] The structure of the outer casing 31 is as follows Figure 14 As shown, an arc-shaped groove 311 is provided on the side facing the screen 20, and the cross-sectional view of the outer casing 31 is shown below. Figure 15 As shown.
[0088] In summary, the functional principle of the gimbal device in this application embodiment is as follows: When the user wants to turn on the device, they only need to manually rotate the screen 20. At this time, the roller 321 will move along the petal-shaped track of the outer shell 31. When the screen 20 is manually rotated to the 45° position, the elastic element 323 is stretched to the maximum value and generates a pulling force. When the screen 20 is rotated more than 45°, because the petal-shaped track of the outer shell 31 has a sloping arc, the screen 20 will generate a force to automatically rotate to 90°. When the screen 20 is rotated to the 90° position, the angle sensor 50 under the screen pivot 21 can sense that the screen is at the 90° position and trigger the device to turn on. When the user wants to turn off the device, they only need to rotate the screen 20 more than 45° again, and the screen will automatically return to the 0° or 180° position and trigger the angle sensor 50 again to turn off the screen 20.
[0089] When the scroll wheel 321 is at the 0°, 90°, 180° and 270° positions, due to the petal-shaped track and the elastic element 323, the scroll wheel 321 will have a certain self-locking force, which can prevent the screen 20 from rotating and shaking. A certain amount of torque is required to make the screen 20 rotate.
[0090] In addition, since the petal-shaped track is connected on all four sides, there is no restriction when the user rotates the screen 20. It can rotate clockwise or counterclockwise, and the rotation angle can reach 360° or even more than 720° without restriction. It can automatically turn on when it rotates to 90° and 270°, and automatically turn off when it rotates to 0° and 180°.
[0091] A gimbal device according to an embodiment of this application includes: a camera module, a screen, a main body, and a connecting arm assembly. One end of the connecting arm assembly is connected to the main body, and the other end of the connecting arm assembly is connected to the camera module. The main body includes a housing and a rotating device. The screen is rotatably connected to the housing via the rotating device. The housing has an arc-shaped groove on the side facing the screen. One end of the rotating device is disposed in the arc-shaped groove, and the other end of the rotating device is connected to the screen. When the rotating device moves within the arc-shaped groove, it can drive the screen to rotate relative to the main body. Thus, in this embodiment, the function of controlling the screen rotation of the gimbal device can be achieved using only a low-cost mechanical structure such as a rotating device and an arc-shaped groove. Compared to using expensive magnets and motors, this method not only simplifies the structure and makes it easier to implement, but also reduces structural costs.
