The terms "mounted," "connected," "fixed," and the like are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. Furthermore, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated; thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; "plurality" means two or more; "and/or" includes any and all combinations of one or more of the associated listed items. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

The relative position change can take place between each part of constituteing the cloud platform to make the space or the volume that the cloud platform occupy change, thereby can adapt to the different needs of shooing and carrying. In the present application, for the sake of presentation, the term "folded state" is used to indicate that the head is in a non-use state in which the volume of occupied space is small and it is convenient to carry, while the term "unfolded state" is used to indicate that the head is in a use state in which the volume of occupied space is large.

As shown in fig. 1, a cloud deck 1 provided in the embodiment of the present application includes: handle 10, folding structure 20, and locking structure 30.

Wherein the handle 10 is a portion to be held by a user. It may be cylindrical or other strip shape extending lengthwise. In the present embodiment, for the sake of convenience of distinction, the two ends of the handle 10 that are away from each other in the longitudinal direction X1 are referred to as a "first end portion" and a "second end portion", respectively.

The folded structure 20 is a deformable portion made up of a plurality of movably connected components. Which can be switched between an unfolded state and a folded state by a change in the relative positions of the components. In the unfolded state, at least a portion of the folding structure 20 will be remote from the second end of the handle, to facilitate the use of the head. In the folded state, the corresponding part of the folding structure 20 can be retracted to contact with the second end of the handle, thereby reducing the space occupied by the head.

The locking structure 30 is a locking device that achieves interlocking between the two components. Any suitable implementation may be selected according to the actual requirements, as long as the folding structure can be locked on the second end of the handle in the folded state.

One of the advantages of the cloud platform that this application embodiment provided is: the folding locking of cloud platform can be realized through simple operation, user's operating procedure has effectually been simplified, has brought good use experience for the user and has felt.

In some embodiments, the folding structure 20 may include several pivotally connected shaft arms. The shaft arms are rotatably connected with each other, so that the holder has rotational freedom degrees in a plurality of different axial directions. In the present embodiment, the first shaft arm 21 and the second shaft arm 22 are described as an example. However, as can be understood by those skilled in the art, a greater number of shaft arms may be selected according to the needs of actual situations, so that the pan-tilt has more freedom of movement.

The first shaft arm 21 is a member rotatably connected to the first end of the handle 10. It may in particular be rotatably connected to the handle 10 in any suitable manner, as long as it is rotatable relative to the handle 10.

The second arm 22 is a member which is in contact with the second end of the handle 10 in the folded state and is remote from the second end of the handle in the unfolded state. Which like the handle 10, may also be a strip-shaped member having a length with a first end and a second end remote from each other. In this embodiment, the end of the second arm 22 that contacts the second end of the handle when in the folded state may be referred to as the second end.

Specifically, in the case where the folding structure is composed of the first shaft arm and the second shaft arm, the first end of the second shaft arm 22 is rotatably connected to the first shaft arm 21, and the second end of the second shaft arm 22 is a portion which is in contact with the second end of the handle.

In some embodiments, the locking structure 30 may include a first locking mechanism 31 and a second locking mechanism 32 disposed in a mating manner.

Wherein the first and second latch mechanisms 31, 32 may be provided on the second end of the handle and the second axle arm, respectively. In the folded state, the first and second locking mechanisms 31, 32 may be engaged with each other such that the second arm is locked to the second end of the handle. In other words, the first and second lock mechanisms are disengaged from each other in the unfolded state, and are brought into contact with each other and locked when switched to the folded state. In the present embodiment, the first lock mechanism 31 is provided at the second end of the handle, and the second lock mechanism 32 is provided at the second shaft arm. It will be understood by those skilled in the art that the positions of the two locking mechanisms can be interchanged according to the actual requirements.

In particular, the first locking mechanism 31 may be a recess, such as a counter-sunk hole, provided at the second end of the handle. Accordingly, the second locking mechanism 32 may protrude from the surface of the second shaft arm, and may be an elastic body having elastic deformation capability, such as silicone rubber and rubber.

During the actual locking process, the elastic body can be pressed and fixed in the recess, and a damping force for limiting the rotation of the handle 10 in the length direction X1 is formed.

One of the advantages of the cloud platform that this application embodiment provided is: the second shaft arm can be conveniently locked on the handle through the elastic body and the recess. Moreover, the locking method can also ensure that the handle and the second shaft arm cannot rotate relatively, and ensure the locking effect of the holder in a folded state.

In some embodiments, the second locking mechanism 32 may also be an elastomer having a non-circular shape, such as a prism or truncated pyramid. Correspondingly, the first locking mechanism 31 may be a blind hole provided at the second end of the handle. The blind bore may be of a suitable profile or size to the elastomer to allow the elastomer to be received within the blind bore for an interference fit therebetween. The prism or truncated pyramid shaped elastomer described above may provide a better secure locking action to prevent relative rotation between the handle and the second shaft arm.

In some embodiments, at least a portion of the inner wall of the recess may be further provided with threads to form a fitting interface. The accessory mounting interface can allow at least one accessory to be detachably mounted on the handle to help realize other auxiliary functions of the holder. In particular, the accessory may be any suitable type of accessory, such as a tripod or a retaining clip.

During the practical use process of the holder in the unfolding state, other accessories can be screwed and fixed at the second end part of the handle in a threaded connection mode. When the tripod head is not used, the accessory is detached from the handle in a reverse screwing mode, and the tripod head is further switched to the folding state.

It should be noted that the above-mentioned "first locking mechanism" and "second locking mechanism" are used only for defining the position where the locking mechanism is provided, and do not limit the specific implementation thereof. For example, the first locking mechanism and the second locking mechanism may be two magnetic bodies that attract each other, and the fixed connection between the two may be achieved by magnetic attraction. The magnetic material may be a magnet capable of forming a magnetic field by itself, or may be a metal material capable of being magnetized by the magnet, and is not particularly limited.

One of the advantages of the cloud platform that this application embodiment provided is: the mode of mutual attraction of the magnetic bodies can provide great convenience for the operation of a user, and the second shaft arm can be locked only by swinging to a corresponding position.

In some embodiments, as shown in fig. 1, the cradle head may further include: a device holding mechanism 40.

The device fixing mechanism 40 is a component for housing and fixing at least one imaging device 2 (e.g., a mobile phone or a camera). Any suitable type of fixing mechanism can be selected according to the actual requirements, and only the fixing mechanism can be matched with the size of the shooting device. Such as a clasping clamp as shown in fig. 1.

Specifically, the device fixing mechanism 40 may be detachably fixed to the second shaft arm. Any suitable detachable connection mode can be selected according to the needs of the actual situation, including but not limited to magnetic attraction, snap, buckle, threaded connection, adhesion and the like. Such a removable design facilitates easy replacement of different device securing mechanisms 40 to accommodate securing of different camera devices.

In some embodiments, the device securing mechanism 40 may be disposed on a surface of the second arm 22 facing away from the locking structure 30. In other words, the second locking mechanism 32 and the device fixing mechanism 40 may be disposed on two opposite surfaces of the second shaft arm 22, respectively. In the present embodiment, the surface on which the second locking mechanism 32 is provided is referred to as "first surface" for convenience of explanation, and the surface on which the device fixing mechanism 40 is provided is referred to as "second surface". As shown in fig. 1, the device fixing mechanism 40 can be kept away from the handle in the folded state by disposing the second locking mechanism 32 and the device fixing mechanism 40 on the first surface and the second surface, respectively.

One of the advantages of the cloud platform that this application embodiment provided is: the design of the equipment fixing mechanism can ensure that the shooting equipment fixed on the cloud deck can not interfere with parts of cloud decks such as a shaft arm and the like in the folding process and after the folding. From this, need not to dismantle and shoot equipment 2 to can be carried and accomodate together with the cloud platform that is in fold condition, very big improvement the use convenience, brought good use for the user and experienced the sense.

In order to fully explain the working process of the pan/tilt head 1 according to the embodiment of the present application. The following is described in detail with reference to the head in a folded state shown in fig. 1 and the head in an unfolded state shown in fig. 4.

As shown in fig. 4, when the head is in the deployed state, the first axial arm 21 and the handle 10 are away from each other. The pan/tilt head 1 has a long total length (approximately equal to the sum of the lengths of the handle 10 and the first pivot arm 21), and can meet the user's requirements for self-photographing or some other similar photographing.

When the pan/tilt head 1 needs to be folded after the shooting is finished, the first shaft arm 21 may be rotated with respect to the handle 10 so as to approach each other. As shown in fig. 1, in the folded state, the projection of the first pivot arm 21 overlaps the handle 10, so that the overall length of the head 1 is significantly shortened (approximately equal to the length of the first pivot arm 21) for convenient carrying.

Specifically, the case where the projection of the first shaft arm 21 overlaps the handle 10 will be described in detail by taking fig. 2 and 3 as an example. For convenience of presentation, a surface of the cradle head in the folded state, which is close to the handle 10, of the first shaft arm 21 is referred to as a third surface, and a surface of the first shaft arm 21, which is away from the handle 10, is referred to as a fourth surface. As shown in fig. 2, in the folded state, when viewed from the direction A1 looking at the third surface of the first shaft arm 21, the orthographic projection of the handle 10 may fall within the range of the first surface of the first shaft arm 21, and at least a part of the first shaft arm 21 is blocked by the handle 10; as shown in fig. 3, most of the handle 10 is hidden by the first shaft arm 20 when viewed from the direction A2 looking at the fourth surface of the first shaft arm 21. Thus, in the present embodiment, the term that the projections of the first shaft arm 21 and the handle 10 overlap is used to indicate that the two members are close to each other in the longitudinal direction, thereby achieving the effect of folding and reducing the length.

With continued reference to fig. 1, in the folded position, the second end of the handle 10 contacts at least a portion of the second arm 22. This may be achieved by providing a suitable structural design, such as a handle having a suitable length or a second arm 22 inclined towards the handle, which is not specifically limited herein.

The second locking mechanism 32 located on the second shaft arm 22 may be located in the area where the second shaft arm 22 contacts the second end of the handle 10. Thereby, the second lock mechanism 32 and the first lock mechanism 31 can be engaged with each other and locked, and the first shaft arm 21 and the second shaft arm 22 can be kept at fixed positions in the folded state without being rotated or moved.

In addition, the device fixing mechanism 40 can be always kept facing away from the handle throughout the folding process, so that the photographing device clamped and fixed therein does not interfere with the folding process and does not need to be particularly taken out.

In some embodiments, as shown in fig. 5, the first shaft arm 21 may include: a rotating member 211 and a first shaft arm body 212.

Wherein, the rotating member 211 is rotatably fitted over the first end of the handle 10. It also has a self-rotating center, outwardly extending connecting portion 213 for rotatably connecting with the first shaft arm body 212.

The rotating member 211 is fitted over the handle 10 and can rotate about a rotation center X21 (i.e., a longitudinal direction of the handle). The first shaft arm body 212 is also rotatably connected to the connecting portion 213, so that the first shaft arm body 212 can rotate around the rotation axis X22, and the second shaft arm at the other end can move away from or approach the second end of the handle. Thus, the pan/tilt head can be provided with a degree of freedom in the rotational axes X21 and X22 by the additionally provided turning member 21.

In some embodiments, as shown in fig. 6 and 7, the first shaft arm 21 may further include: a plurality of stopper protrusions 214 and stopper grooves 215.

Wherein, the limit projection 214 is provided at one end of the first shaft arm body 212 rotatably connected with the connection part 213. The limiting groove 215 is matched with the limiting protrusion 214 and is positioned on the surface of the connecting part close to the first shaft arm body. When the connecting portion 213 rotates around the first axle arm body 212 to a target angle, the limiting protrusion 214 is caught in the limiting groove 215 to help the first axle arm body 212 reliably rotate to a specific angle.

In the present embodiment, the term "target angle" is used to denote the rotation angle of the first axle arm body 212. The first target angle when the cloud platform is in the unfolding state and the second target angle when the cloud platform is in the folding state are included.

One of the advantages of the cloud deck of the embodiment of the application is that: through the additional limiting protrusion and the additional limiting groove, the cradle head can be reliably switched between the folded state and the unfolded state, unnecessary swinging or dislocation cannot occur, and the use reliability of the cradle head is ensured.

In some embodiments, with continued reference to fig. 6, the connection portion 213 includes a connection housing 213a, a rotation shaft 213b, and a limiting mechanism 213c.

Among them, the connection housing 213a is a hollow housing connected between the rotation center X21 of the rotation member 211 and the first shaft arm body 212; the rotation shaft 213b extends outward from the rotation center X21 of the rotation member 211 along the length direction X22 of the connection housing 213a. As shown in fig. 7, the end of the rotation shaft 213b away from the rotation center X21 extends into the first arm body 22 after passing through the shaft hole 212a pre-provided in the first arm body 212.

Specifically, an annular housing chamber 213d can be formed between at least a part of the rotary shaft 213b housed in the connecting housing 213a and the connecting housing 213a. The stopper mechanism 213c has an annular shape that fits the rotary shaft 213b or the annular housing chamber 213d. The stopper mechanism 213c is fitted around the rotary shaft 213b through a through hole provided at the center thereof and is fixedly housed in the annular housing chamber 213d. Referring to fig. 6 and 7, a plurality of limiting protrusions 214 are disposed on the edge of the axle hole 212a of the first axle arm body 212. Accordingly, the limiting mechanism 213c is provided with a plurality of limiting grooves 215, and the plurality of limiting grooves 215 are disposed on the surface of the annular limiting mechanism 213c.

In some embodiments, the stop protrusion 214 may be a prismoid-like protrusion. The limiting recess 215 includes at least one set of inclined side walls 215a corresponding to the truncated pyramid-shaped protrusions, and the set of inclined side walls 215a are disposed opposite to each other along the rotation direction of the first shaft arm body 212 around the connection portion 213. When the rotating member 211 and the first shaft arm body 212 rotate relatively, the inclined side wall 215a facilitates the frustum-shaped limiting protrusion 215 to slide into the limiting groove 215 and slide out of the limiting groove 215, so as to avoid being locked.

In actual use, a user may apply an external force to the rotating member 211 or the first shaft arm body 212 to rotate the rotating member 211 relative to the first shaft arm body 212, and when the rotating member 211 rotates, each of the limiting recesses 215 is successively engaged with the limiting protrusions 214. The limiting groove 215 and the limiting protrusion 214 are locked with each other, so that the rotating member 211 keeps the relative position between the rotating member 211 and the first shaft arm body 212 stable after each rotation, and the shaking is avoided.

In some embodiments, the number of the limiting grooves 215 or the limiting protrusions 214 is four, and may be distributed on the circumferential edge of the limiting mechanism 213c or the shaft hole 212a. Specifically, the stopper groove 215 and the stopper protrusion 214 may be asymmetrically arranged such that the angle of rotation of the rotary member 211 or the handle 10 with respect to the first arm body 212 is 180 degrees for the rotary member 211 and the first arm body 212 every time the engagement occurs.

It will be understood that the number of the limiting protrusions 214 or the limiting grooves 215 may also be two, three, five or even more, and when the number of the limiting grooves 215 or the limiting protrusions 214 is larger, the rotation angle of the rotating member 211 per rotation of the first shaft arm body 212 is smaller, which is more advantageous for accurately adjusting the relative position (angle) relationship between the handle 10 and the first shaft arm 21.

In some embodiments, with reference to fig. 6, the first connection portion 213 further includes a rotation angle limiting protrusion (a start protrusion 213e and a stop protrusion 213 f) protruding from the surface of the connection housing 213 a; in addition, a stop protrusion 212b is disposed on an end of the first shaft arm body 212 close to the rotating member 211, and the stop protrusion 212b is protruded on a side surface between the first surface and the second surface of the first shaft arm body 212. When the rotation member 211 rotates relative to the first shaft arm body 212, the rotation angle restricting protrusion may contact the stopping protrusion 212b, thereby restricting the rotation member 211 or the handle 10 from further rotating relative to the first shaft arm body 212.

Specifically, the rotation angle limiting protrusion includes a start protrusion 213e and a stop protrusion 213f, and in the embodiment of the present application, the start protrusion 213e and the stop protrusion 213f are respectively distributed at two ends of the connection housing 213a in the same radial direction along the circumferential surface of the connection housing 213a.

Wherein, when the start projection 213e abuts against the stop projection 212b, the tripod head is in a folded state. When the stop projection 213f abuts against the stop projection 212b, the pan/tilt head 1 is in the deployed state. In the process of changing from the contact between the start projection 213e and the stop projection 212b to the contact between the end projection 213f and the stop projection 212b, the rotational member 211 rotates 180 degrees in the first rotational direction (for example, counterclockwise) with respect to the first arm body 212, and the pan/tilt head 1 gradually changes from the folded state to the unfolded state in this process.

In the process of changing from the contact between the stop protrusion 213f and the stop protrusion 212b to the contact between the start protrusion 213e and the stop protrusion 212b, the rotational member 211 is rotated 180 degrees in the second rotational direction (for example, clockwise) with respect to the first arm body 212, and the pan/tilt head 1 is gradually changed from the unfolded state to the folded state in this process.

In some embodiments, the head may be an accessory device with a built-in circuit module (not shown) capable of providing one or more functions. For example, the circuit module may be communicatively connected to the shooting device 2, so that a user may indirectly trigger the shooting device 2 to implement a corresponding function, such as turning on, shooting, recording, pausing, turning off, and the like of the shooting device 2, by pressing a function button or switch on the handle 10.

It should be noted that the specific implementation of the circuit module is not limited in this application. Which in particular can be set by the skilled person as required by the actual situation. It can be understood that, for a pan-tilt head with a built-in circuit module, there are two different operating states of "on" and "off" according to whether the circuit module is started to operate or not.

In some embodiments, as shown in fig. 8, the cradle head may further include: a switch assembly 50 and a trigger mechanism 60.

The switch assembly 50 is a member that can be switched between an on state and an off state. Which is connected to a circuit module built in the head to enable or disable the head accordingly.

The trigger mechanism 60 is a movable mechanism linked with the first shaft arm 21, and is capable of applying a mechanical force to the switch assembly 50 to switch it between the on and off states when the first shaft arm 21 is rotated to a target angle. As described in the above embodiments, the target angle includes the first target angle at which the tripod head is in the unfolded state and the second target angle at which the tripod head is in the folded state.

One of the advantages of the cloud platform that this application embodiment provided is: through the trigger mechanism and the switch assembly which are additionally arranged, the cloud platform is started or closed with the cloud platform to be linked when being switched between the unfolding state and the folding state.

In some embodiments, the switch assembly 50 may include at least one pair of contacts (not shown) and a transmission 51. The transmission member 51 can make or break at least one pair of contacts through mechanical acting force acting on the transmission member 51, so as to control the starting and the closing of the tripod head. Specifically, the transmission member may be a push pin, a button, a lever, a roller, or the like.

The trigger mechanism 60 is implemented primarily by a cam 61. The cam 61 is a member provided in the first shaft arm. Which is capable of contacting the transmission member 51 over at least a part of the rotational angle range, thereby applying a mechanical force to the transmission member 51.

The cam 61 may be coupled to the first shaft arm 21 using any suitable type of mounting arrangement as the case requires. For example, the cam 61 is fit-fixed to the end of the rotation shaft 213b by some connecting member (e.g., screw connection).

One of the advantages of the cloud platform that this application embodiment provided is: can trigger the switch subassembly through cam structure when the cloud platform is in the expansion state and realize the automatic start of cloud platform to when the cloud platform is in fold condition, make it can break away from the contact with the driving medium along with the rotation of rotation axis 211b, thereby make switch subassembly automatic re-setting realize the self-closing of cloud platform.

In some embodiments, the head may further include additional sound emitting components. The sound emitting assembly may be housed within any suitable component within the head, such as within the first axial arm, within the second axial arm, or within the handle.

The sounding component can be linked with the starting and closing states of the holder, and a preset sound effect is given out in response to the condition that the switch component is switched from the off state to the on state and/or the switch component is switched from the on state to the off state. The skilled person can choose to set specific sound effects, such as specific buzzing sounds or warning sounds, according to the needs of the actual situation, and is not limited in detail herein.

Specifically, this sound production subassembly can be the electrical components of circuit module in the electrical connection cloud platform. Therefore, the sound effect can be correspondingly produced as the cradle head is triggered to be started and powered up due to the state change of the switch assembly. Alternatively, the sound generating assembly may also be a mechanical bell, bell or similar sound generating mechanism. The trigger mechanism is engaged with the sound emitting assembly and is also capable of applying a mechanical force to the sound emitting assembly to emit sound when the first shaft arm is rotated to a target angle in a manner similar to the switch assembly.

In some embodiments, the head may further comprise a number of motors. The motor can drive the rotation of each shaft arm in the folding structure under the control of the circuit module so as to keep the shooting device at a desired shooting position (for example, as a stabilizer to keep the shooting device stable during movement).

As shown in fig. 7 and 8, a heading motor 23 may be disposed in the rotating member 211 of the first shaft arm 21, and a tilt motor 24 may be disposed in the first shaft arm body 212 of the first shaft arm 21.

Wherein, the heading motor 23 is used for driving the first shaft arm 21 to rotate relative to the handle 10, so as to realize the rotation around X21 (i.e. heading shaft). The pitch motor 24 is used for driving the second shaft arm 22 to rotate relative to the first shaft arm 21, so as to realize rotation around the X23 (i.e. pitch axis). Specifically, the sound emitting assembly may include the heading motor 23 described above. For example, as the cradle head is switched to the on state, the heading motor 23 is powered on to generate a specific sound effect, so as to prompt the user that the cradle head is turned on.

The following describes in detail a control process of automatically opening and closing the cradle head in the unfolded state and the folded state, which is provided by the embodiment of the present application, with reference to a specific scenario. In this embodiment, the description will be given by taking an example in which the cradle head is automatically opened when the cradle head is in the unfolded state and the cradle head is automatically closed when the cradle head is in the folded state.

During the transition between the folded state and the unfolded state of the head 1, the rotating member 211 rotates with respect to the first axis arm body 212. When the folding state is changed into the unfolding state, as the rotation between the rotating part 211 and the first shaft arm body 212 is carried out, the transmission piece 51 of the switch assembly 50 gradually slides from the proximal part L1 to the distal part L2 of the cam 61 relative to the cam 61, the transmission piece 51 of the switch assembly is triggered to enable the switch to enter the switching-on state, and the tripod head is automatically opened.

When the unfolding state is changed into the folding state, along with the rotation between the rotating part 211 and the first shaft arm body 212, the transmission piece 51 of the switch assembly slides to the proximal part L1 from the distal part L2 of the cam 61 gradually relative to the cam 61, the mechanical acting force on the transmission piece 51 of the switch assembly is removed, the switch assembly is reset, and the tripod head is automatically closed.

As shown in fig. 9 and 10, it should be noted that the proximal portion L1 of the cam 61 is a portion closest to the rotation center O of the cam 61 on the sliding path of the cam 61, and the distal portion L2 of the cam 61 is a portion farthest from the rotation center O of the cam 61 on the sliding path of the cam 61. The proximal portion L1 and the distal portion L2 may each be a circular arc, the radius R1 of the proximal portion L1 is smaller than the radius R2 of the distal portion L2, and the proximal portion L1 and the distal portion L2 together form at least a part of the sliding track of the cam 61. The sliding track is formed by the contact point of the cam 61 with the transmission member 51 when it rotates.

The foregoing is a further detailed description of the present application in connection with specific/preferred embodiments and is not intended to limit the present application to that particular description. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
