Description

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 30, 2019, with application number 201910817431X and invention name “Foldable pan-tilt head”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of pan / tilt platforms, and in particular to a pan / tilt platform. Background Art

[0003] As mobile phones become more powerful, more and more people are taking photos with their phones.

[0004] When holding a phone to shoot, hand shaking can cause the captured image to shake, reducing the quality of the shot. This is why gimbals (PTZs) have emerged. These devices, similar to selfie sticks, hold the phone in place. When operating, they produce an opposite motion to the hand's, ensuring the phone remains relatively stable while shooting, resulting in smooth, shaky images.

[0005] However, traditional gimbals are large in size and inconvenient to carry. How to improve the portability of gimbals has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] Based on this, it is necessary to provide a pan / tilt platform to address the above technical issues.

[0007] A pan / tilt head, comprising a handle, a first arm, a second arm, and a clamping member connected in sequence, wherein the second arm comprises a second connecting portion and a second rod portion; and further comprising:

[0008] a first driving member connecting the handle and the first arm to drive the first arm to rotate relative to the handle;

[0009] a second driving member, connecting the second connecting portion and the second rod portion in the second arm to drive the second rod portion to rotate relative to the second connecting portion; and

[0010] a third driving member, connecting the second rod portion and the clamping member to drive the clamping member to rotate relative to the second rod portion;

[0011] The second connecting portion is rotatably connected to the first arm so that the gimbal can be folded or unfolded. After the gimbal is folded, the second driving member, the third driving member and the first driving member are arranged in sequence along the axial direction of the handle.

[0012] In one embodiment, the first arm includes a first connecting portion and a first rod portion, the first connecting portion is connected to the handle, and the first rod portion is connected to the second connecting portion.

[0013] In one embodiment, the second connecting portion is rotatably connected to an end of the first rod portion away from the first connecting portion.

[0015] In one embodiment, the first rod portion is connected to a peripheral side of the first connecting portion, so that a space for accommodating at least a portion of the clamping member and at least a portion of the second arm is formed between the first rod portion and the first connecting portion.

[0016] In one embodiment, the first rod portion is a bent rod, and when the platform is folded, the clamping member can clamp the handle, and the clamping member is spaced apart from the first rod portion;

[0017] Or the first rod portion is a straight rod, and the first rod portion extends along the axial direction of the handle. After the gimbal is folded, the clamping member can clamp the first rod portion and the handle.

[0018] In one embodiment, a first holding structure is provided on the first support arm, and a second holding structure is provided on the handle. When the first support arm rotates relative to the handle until the first holding structure abuts against the second holding structure, the rotation of the first support arm relative to the handle is locked.

[0020] In one embodiment, a hinge portion is provided on the second connecting portion, a through hole is provided on the hinge portion, a groove is provided on the first rod portion, side walls are provided on both sides of the groove, and the hinge portion is provided in the groove; and a threaded member is also included, the threaded member passes through one of the side walls and the through hole on the hinge portion and is threadedly connected to the other side wall, and by turning the threaded member, the two side walls can clamp the hinge portion.

[0021] In one embodiment, one of a protrusion or a concave hole is provided on the hinge portion, and the other of the protrusion or the concave hole is provided on the side wall of the groove, and the protrusion can be accommodated in the concave hole.

[0022] Beneficial effect: After folding, the position of the foldable part of the gimbal is roughly along the axial direction of the handle, that is, compared with the unfolded state of the gimbal, after folding, the longitudinal size of the gimbal becomes smaller, and the circumferential size of the gimbal is slightly increased, or the circumferential size of the gimbal remains unchanged, or the circumferential size of the gimbal is reduced, which makes it convenient to insert the gimbal into a narrow space such as a pocket for storage and carrying, greatly facilitating the carrying of the gimbal.

DETAILED DESCRIPTION

[0034] To facilitate understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the present disclosure.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. Conversely, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0036] Figure 1 This is a front view of the folded platform in the first embodiment. Figure 2 for Figure 1 Exploded view of the gimbal in [Image file name]; Figure 3 for Figure 1 A stereoscopic view of the pan / tilt head is shown.

[0037] like Figure 1-Figure 3 As shown, the gimbal includes a handle 300. In one usage scenario, the handle 300 can serve as a grip, i.e., a person can hold the gimbal by holding the handle 300. In another usage scenario, the handle 300 can be supported by a support base, which supports the gimbal. The support base can be placed in a vehicle or other location where a stable shooting environment is required.

[0038] The gimbal can hold a mobile phone. The gimbal includes three driving parts, namely a first driving part 11, a second driving part 12 and a third driving part 13. When the gimbal is unfolded, the three driving parts are arranged in a three-dimensional space, so that the mobile phone can move in three-dimensional space. For example, when the handle 300 held by the hand is offset, the sensor in the gimbal can sense the offset angle, and then generate a corrective movement in the three-dimensional space through the three driving parts, ultimately keeping the mobile phone installed on the gimbal able to shoot in a relatively stable state.

[0039] like Figure 1-Figure 3 As shown, the gimbal includes a first arm 100 and a second arm 200. One end of the first arm 100 is connected to the handle 300, and the other end of the first arm 100 is connected to the second arm 200. Specifically, the first arm 100 is hinged to the second arm 200. Figure 3 As shown, the axis of the hinge shaft is m, so that the second arm 200 can rotate around the hinge shaft m and then fold toward the handle 300.

[0040] In one embodiment, Figure 1 and Figure 2 As shown, the first arm 100 includes a first connecting portion 110 and a first rod portion 111 fixedly connected to each other. The handle 300 can be in the shape of a strip or a cylinder. Figure 1 As shown, the rotation axis of the first driving member 11 is the first rotation axis a, the rotation axis of the second driving member 12 is the second rotation axis b, and the rotation axis of the third driving member 13 is the third rotation axis c. In one embodiment, when the gimbal is folded, the first rotation axis a, the second rotation axis b, and the third rotation axis c are all in the same plane. The first connecting portion 110 is connected to the handle 300 by rotation around the first rotation axis a.

[0041] like Figure 1 and Figure 2 As shown, the second arm 200 includes a second connecting portion 210 and a second rod portion 211 that are detachably connected, and the second connecting portion 210 and the second rod portion 211 are rotatably connected. Figure 1 As shown, the second connecting portion 210 and the second rod portion 211 are connected to rotate around the second rotation axis b. Figure 3 The second connecting portion 210 is rotatably connected to an end of the first rod portion 111 away from the first connecting portion 110 around the hinge axis m.

[0042] like Figure 1-Figure 3 As shown, the platform further includes a clamping member 400, which is used to clamp a mobile phone or other photographic equipment. The clamping member 400 is rotatably connected to the second rod portion 211, as shown in FIG. Figure 1 As shown, the clamping member 400 is rotatably connected to the second rod portion 211 around the third rotation axis c.

[0043] Figure 4for Figure 1 The structural diagram of the pan-tilt platform is shown in FIG. 1 . The process of the pan-tilt platform is to manually rotate the second arm 200 around the hinge axis m relative to the first arm 100, and then turn on the pan-tilt platform switch k, and the pan-tilt platform automatically completes the subsequent expansion process. Figure 1 and Figure 4 The first driving member 11 drives the first arm 100 to rotate relative to the handle 300 around the first rotation axis a, the second driving member 12 drives the second rod portion 211 to rotate relative to the second connecting portion 210 around the second rotation axis b, and the third driving member 13 drives the clamping member 400 to rotate relative to the second rod portion 211 around the third rotation axis c. Figure 1 and Figure 4 As shown, the pan / tilt switch k is turned off, and the first, second, and third driving members 11, 12, and 13 of the pan / tilt head are activated, completing the reverse steps described above. The second arm 200 is then manually rotated relative to the first arm 100 about the hinge axis m, so that the clamping member 400 contacts the handle 300 or the first connecting portion 110. When folding, the second arm 200 and the clamping member 400 move as a whole toward the handle 300.

[0044] like Figure 1 As shown, the final state after folding is that along the direction of the axis of the handle 300 ( Figure 1 ), are the second drive member 12, the third drive member 13 and the first drive member 11 in sequence. For example, after folding, the third drive member 13 is located between the second drive member 12 and the first drive member 11 along the vertical direction. In the present application, after folding, the location where the foldable portion of the gimbal is stored is roughly along the axial direction of the handle 300. That is, compared with the unfolded state of the gimbal, after folding, the longitudinal dimension of the gimbal becomes smaller, and the circumferential dimension of the gimbal is slightly increased, or the circumferential dimension of the gimbal remains unchanged, or the circumferential dimension of the gimbal is reduced, thereby making it easier to insert the gimbal into a narrow space such as a pocket for storage and carrying, greatly facilitating the portability of the gimbal.

[0045] Specific as Figure 1 As shown, after folding, the clamping member 400 is tilted relative to the first rotation axis a. The first rod portion 111 is connected to the periphery of the first connecting portion 110. The first rod portion 111 can also be positioned off-center from the first connecting portion 110. Therefore, after folding, the clamping member 400 is generally accommodated in the area enclosed by the handle 300 and the first rod portion 111. As a result, the clamping member 400 does not rest against the periphery of the handle 300 over a large area. As a result, the circumferential volume of the gimbal does not increase significantly after folding, resulting in an overall slender shape that can be easily inserted into a pocket for easy carrying.

[0046] contrast Figure 1 and Figure 4After the platform is folded, the relative position relationship between the first rotation axis a and the second rotation axis b changes, while the relative position relationship between the second rotation axis b and the third rotation axis c remains unchanged. Figure 1 As shown, when the gimbal is folded, the second axis b and the first axis a are approximately parallel. Furthermore, to minimize the gimbal's circumferential size around the handle 300, the spacing between the first axis a and the second axis b is controlled to be within 1 cm. It should be understood that, in this application, the second axis b and the first axis a being approximately parallel specifically refers to the actual positional relationship between the second axis b and the first axis a being parallel within an allowable error range, such as 0°-5°. Furthermore, optimal spacing between the first axis a and the second axis b is 0, i.e., when the first axis a and the second axis b coincide.

[0047] Figure 5 FIG. 1 is an exploded view of the pan / tilt platform in the second embodiment of the present application. The main difference between the pan / tilt platform and the first embodiment is the shape of the first arm 100. Figure 1 In the embodiment shown, the first rod portion 111 of the first arm 100 extends from the first connecting portion 110, first extending obliquely upward, and then extending in a direction parallel to the axial direction of the handle 300, so that the space enclosed between the first arm 100 and the handle 300 is larger. When a mobile phone is mounted on the gimbal, more space for the mobile phone to move around is provided. Figure 5 As shown, the first rod portion 111 in the first arm 100 starts from the first connecting portion 110 and extends directly upward in a direction parallel to the axis of the handle 300. At this time, the circumferential space of the gimbal is smaller, making it easier to store and carry.

[0048] Figure 6 for Figure 5 The schematic diagram of the embodiment shown is after the pan / tilt head is unfolded. Figure 4 and Figure 6 As shown, in the two embodiments of the gimbal, when fully extended, the first rotation axis a, the second rotation axis b, and the third rotation axis c are non-parallel to each other, allowing the clamping member 400 to rotate in three dimensions relative to the handle 300. In one embodiment, when the gimbal is fully extended, the first rotation axis a and the second rotation axis b are spatially perpendicular. If the second rotation axis b and the third rotation axis c are translated into the same plane, the second rotation axis b and the third rotation axis c are non-perpendicular, and the angle between them is acute or obtuse. This allows a larger space for the clamped mobile phone to rotate, minimizing interference with the mobile phone's movement by the gimbal.

[0049] In one embodiment, Figure 2 and Figure 5As shown, the second connecting portion 210 is provided with an outwardly protruding hinge portion 210A, and a through hole 210B is provided on the hinge portion 210A. The first rod portion 111 is provided with a groove, and the groove has side walls on both sides. The hinge portion 210A is arranged in the groove, and a screw member 14 is passed through one of the side walls and the through hole 210B on the hinge portion 210A in sequence and is threadedly connected to the other side wall. When the knob screw member 14 is turned, the two side walls can be pulled close to each other and squeeze the hinge portion 210A located in the groove, thereby achieving locking of the first arm 100 and the second arm 200. To achieve a better locking effect, a plurality of protrusions 210C are provided on the hinge portion 210A, and a plurality of recessed holes are provided on the sidewalls of the groove. The protrusions 210C can move into the recessed holes. When the second arm 200 rotates relative to the first arm 100, the protrusions 210C can shift between different recessed holes. By turning the screw member 14, the two sidewalls can clamp the hinge portion 210A. At this time, the protrusions 210C are accommodated in the recessed holes, thereby achieving a better locking effect. In other embodiments, recessed holes can be provided on the hinge portion 210A, and protrusions 210C can be provided on the sidewalls.

[0050] In one embodiment, Figure 1 As shown, the first driving member 11 is disposed on the handle 300. The first driving member 11 may be a motor. The housing of the first driving member 11 is fixed to the handle 300. The rotating shaft of the first driving member 11 may extend along the direction of the first rotating axis a. The first connecting portion 110 is fixedly connected to the rotating shaft of the first driving member 11. Of course, in one embodiment, the housing of the first driving member 11 may also be fixed to the first connecting portion 110, and the rotating shaft of the first driving member 11 is fixedly connected to the handle 300.

[0051] In one embodiment, the first support arm 100 includes a first connecting portion 110 and a first rod portion 111. The first connecting portion 110 may be a cylinder. The first rod portion 111 is fixed to the side of the first connecting portion 110. In this case, the first rod portion 111 is offset from the first rotation axis a so that a space for accommodating at least a portion of the clamping member 400 and at least a portion of the second support arm 200 is formed between the first rod portion 111 and the first connecting portion 110. Figure 1 As shown, when the platform is folded, at least part of the clamping member 400 and at least part of the second arm 200 are accommodated in the space, so that the various components of the platform are more compact after folding, reducing the volume of the platform. Figure 1In the illustrated embodiment, the first rod portion 111 is curved. The end of the first rod portion 111 proximal to the first connecting portion 110 is proximal to the first rotation axis a, while the end of the first rod portion 111 distal to the first connecting portion 110 is distal to the first rotation axis a. When the gimbal is folded, one end of the clamping member 400 engages the handle 300, while the other end is spaced apart from the first rod portion 111. This creates a larger receiving space between the first connecting portion 110 and the second rod portion 211 for the clamping member 400 and the second arm 200, thus providing more space for the clamping member 400.

[0052] exist Figure 5 In the illustrated embodiment, the first rod portion 111 is elongated, with the length of the first rod portion 111 extending along the first rotation axis a. The first connecting portion 110 is cylindrical, with the central axis of the cylinder extending in the direction of the first rotation axis a, and the length of the first rod portion 111 perpendicular to the end surface of the cylinder.

[0053] exist Figure 5 In the illustrated embodiment, the handle 300 and the first rod portion 111 are both straight rod-shaped, and the lengths of the first rod portion 111 and the handle 300 are substantially the same.

[0054] In one embodiment, Figure 6 As shown, the first arm 100 is provided with a first retaining structure 510, and the handle 300 is provided with a second retaining structure 520. When the first arm 100 rotates relative to the handle 300 about the first rotation axis a until the first retaining structure 510 abuts against the second retaining structure 520, the rotation of the first arm 100 relative to the handle 300 is locked, thereby preventing the first arm 100 from rotating unrestricted relative to the handle 300. After folding, the first retaining structure 510 and the second retaining structure 520 retain each other, making the folded gimbal structure more stable.

[0055] In one embodiment, the first holding structure 510 is a protrusion provided on the first connecting portion 110, and the second holding structure 520 is a groove or protrusion provided on the handle 300. In one embodiment, the first holding structure 510 can also be a groove provided on the first connecting portion 110.

[0056] In one embodiment, Figure 1 As shown, the second driving member 12 can be a motor. The housing of the second driving member 12 is fixed to the second connecting portion 210. The rotating shaft of the second driving member 12 can extend along the second rotating axis b. The rotating shaft of the second driving member 12 is fixedly connected to the second rod portion 211, so that the second driving member 12 can drive the second rod portion 211 to rotate about the second rotating axis b relative to the second connecting portion 210. In one embodiment, the housing of the second driving member 12 can also be fixedly connected to the second rod portion 211, and the rotating shaft is fixedly connected to the second connecting portion 210.

[0057] like Figure 2 As shown, the second rod portion 211 is provided with a first end surface 211A and a second end surface 211B, and the angle between the first end surface 211A and the second end surface 211B is an acute angle. Figure 1 The second rotation axis b is perpendicular to the first end surface 211A, and the third rotation axis c is perpendicular to the second end surface 211B.

[0058] like Figure 1 As shown, the third driving member 13 is a motor, the housing of the third driving member 13 can be fixedly connected to the second rod portion 211 of the second support arm 200, and the rotating shaft is fixedly connected to the clamping member 400. In other embodiments, the housing of the third driving member 13 is fixedly connected to the clamping member 400, and the rotating shaft of the third driving member 13 is fixedly connected to the second rod portion 211 of the second support arm 200.

[0059] like Figure 6 As shown, the clamping member 400 is provided with a first slot 410. Figure 7 for Figure 5 In the structural diagram of the folded platform, when the platform is folded, the first rod portion 111 is partially accommodated in the first slot 410, and the side wall of the first slot 410 of the clamping member 400 can contact the first rod portion 111, so that the clamping member 400 basically does not rotate. Specifically, Figure 6 As shown, the first slot 410 is formed by two first clamping fingers 410A on the clamping member 400. When the gimbal is folded, the two first clamping fingers 410A can be respectively attached to the two sides of the first rod portion 111. At this time, the clamping member 400 can no longer rotate relative to the second arm 200, making the folded gimbal structure more stable.

[0060] like Figure 6 and Figure 7 As shown, the clamping member 400 is further provided with a second slot 420. When the gimbal is folded, part of the handle 300 is accommodated in the second slot 420. For example, the upper portion of the handle 300 is accommodated in the second slot 420. Due to the provision of the first slot 410 and the second slot 420, the rotation of the clamping member 400 relative to the second arm 200 can be restricted by the cooperation between the first slot 410 and the first rod 111, and the cooperation between the second slot 420 and the handle 300 or the first connecting portion 110. In addition, when the gimbal is folded, the first rod 111 is partially accommodated in the first slot 410, and the handle 300 or the first connecting portion 110 is accommodated in the second slot 420. This allows the clamping member 400 to be closer to the handle 300 and the first arm 100. This makes the components more compact when the gimbal is folded, reducing the volume of the folded gimbal.

[0061] In one embodiment, the clamping member 400 is provided with a first buckle, and the handle 300 or the first connecting portion 110 is provided with a second buckle. When the gimbal is folded, the first buckle and the second buckle can be engaged. The engagement of the first buckle and the second buckle can also prevent the clamping member 400 from rotating after folding.

[0062] like Figure 6 As shown, the first and second slots 410 and 420 have different shapes. The shape of the first slot 410 corresponds to the shape of the first rod portion 111, while the shape of the second slot 420 corresponds to the shape of the handle 300 or the shape of the first connecting portion 110. For example, the cross-section of the first arm 100 is generally rectangular, and the first slot 410 is formed by the inner walls of several planes; the handle 300 and the first connecting portion 110 are generally cylindrical, and the inner wall of the second slot 420 is generally arc-shaped.

[0063] Figure 8 for Figure 5 The exploded view of the clamping member 400 is as shown in FIG. Figure 8 As shown, the clamping member 400 includes a support base 430, a first movable base 440, and a second movable base 450. The first movable base 440 and the second movable base 450 are respectively arranged on both sides of the support base 430, and the first movable base 440 can move closer to or farther away from the support base 430, and the second movable base 450 can also move closer to or farther away from the support base 430. The clamping member 400 also includes a plurality of elastic members 460. The first movable base 440 is connected to the support base 430 via two elastic members 460, and the second movable base 450 is connected to the support base 430 via another two elastic members 460. When in use, the second movable base 450 and the first movable base 440 are pulled apart to move them away from each other. The mobile phone is placed against the support base 430, and the first movable base 440 and the second movable base 450 are pulled toward the center by the elastic members 460. The mobile phone is fixed together by the first movable base 440, the second movable base 450, and the support base 430.

[0064] like Figure 8 As shown, the first movable seat 440 includes two first gripping fingers 410A, which are spaced apart and form a first engaging slot 410 between the two first gripping fingers 410A. The second movable seat 450 includes two second gripping fingers 420A, which are spaced apart and form a second engaging slot 420 between the two second gripping fingers 420A. When clamping a mobile phone, the two first gripping fingers 410A, the two second gripping fingers 420A, and the support base 430 jointly contact the mobile phone, thereby improving the clamping security.

[0065] like Figure 8As shown, the support base 430 is flat, so as to better abut the mobile phone and stably fix the mobile phone. In other words, at least the surface of the support base 430 that abuts the mobile phone is flat.

[0066] In one embodiment, Figure 8 As shown, the two first gripping fingers 410A and the two second gripping fingers 420A have gripping grooves 470 on their opposing surfaces. When a mobile phone is mounted on the clamping member 400, the mobile phone fits snugly within the gripping grooves 470, thereby providing a stable grip and preventing the mobile phone from shaking. In this embodiment, the mobile phone does not need to rest against the support base 430.

[0067] In one embodiment, Figure 7 As shown, when the gimbal is folded, the two first gripping fingers 410A are located on either side of the first rod portion 111, and the two second gripping fingers 420A are both in contact with the handle 300. At this point, the support base 430 is tilted relative to the first rotation axis a, meaning that the angle between the support base 430 as a whole and the first rotation axis a is acute. The support base 430 as a whole can be understood as the angle between the plane where the support base 430's longitudinal and width axes intersect and the first rotation axis a is acute.

[0068] Figure 9 This is a three-dimensional diagram of the unfolded pan / tilt head in the third embodiment. Figure 10 for Figure 9 The following embodiments describe the following three-dimensional diagram of the folded platform. Figure 9 and Figure 10 The two-fold platform shown in the figure consists of Figure 9 The expanded state shown collapses to Figure 10 When shown in the fully folded position, two folds are required.

[0069] like Figure 9 As shown, the first arm 100 includes a first connecting portion 110 and a first rod portion 111 that are hinged to each other. The first connecting portion 110 is connected to the handle 300 by rotating around the first rotation axis a. After folding, as shown in FIG. Figure 10 As shown, the first connecting portion 110 and the first rod portion 111 can be locked together using the screw member 14A. The second arm 200 includes a second connecting portion 210 and a second rod portion 211. One end of the second rod portion 211 is pivotally connected to the second connecting portion 210 about a second rotation axis b. The second connecting portion 210 is hinged to the end of the first rod portion 111 away from the first connecting portion 110. After folding, the second connecting portion 210 and the first rod portion 111 can be locked together using the screw member 14.

[0070] like Figure 10As shown, after folding, the first rod portion 111 of the first arm 100 and the second arm 200 are stored on one side of the circumference of the handle 300. The circumference of the handle 300 can be understood as if the handle 300 is a cylinder with a central axis. In practice, the first rotation axis a can be this central axis. Among several straight lines parallel to this central axis, any line that does not pass through the handle 300 can be referred to as a line located on one side of the circumference of the handle 300. After folding, the pan / tilt head of this embodiment has a significantly reduced axial dimension along the central axis of the handle 300, making it easier to store.

[0071] In one embodiment, Figure 10 As shown, after folding, the first rod portion 111 of the first arm 100 is located between the handle 300 and the second arm 200. In this embodiment, after the platform is folded, the various components are arranged more compactly, and the storage space occupied is small.

[0072] In one embodiment, Figure 10 As shown, after folding, the first rotation axis a, the second rotation axis b and the third rotation axis c are coplanar. Figure 9 As shown, when the gimbal is unfolded for use, the first rotation axis a, the second rotation axis b, and the third rotation axis c are distributed in a three-dimensional space, that is, the three rotation axes are not distributed in the same plane. At this time, the first rotation axis a and the second rotation axis b can be arranged in the same plane and vertically. When the gimbal is turned off, the second rod portion 211 is rotated about the second rotation axis b relative to the second connection portion 210 by a certain angle so that the third rotation axis c and the second rotation axis b are coplanar. Since the first rotation axis a and the second rotation axis b can be arranged in the same plane and vertically, the three rotation axes are now in the same plane. Since the three rotation axes are arranged in the same plane, the folded gimbal has a flat structure as a whole, which occupies a small storage space and is easy to carry and store.

[0073] In one embodiment, Figure 10 As shown, after folding, one end of the clamping member 400 abuts against the first rod portion 111, and the other end of the clamping member 400 is a free end. If the clamping member 400 can still rotate freely after folding, it will be inconvenient to store. In this embodiment, after folding, the clamping member 400 abuts against the first rod portion 111, which can prevent the clamping member 400 from rotating freely after folding to a certain extent. In one embodiment, at least a first card slot 410 is provided on the clamping member 400. When the gimbal is folded, the first rod portion 111 is partially accommodated in the first card slot 410. The first card slot 410 and the first rod portion 111 cooperate to better limit the rotation of the clamping member.
