Description

Technical Field

[0001] The present invention relates to the technical field of handheld devices for photographing or videotaping, and in particular to a handheld stabilizer. Background Art

[0002] With the continuous development of shooting stabilizers and gimbals, users' requirements for shooting and storage of stabilizers and gimbals are gradually increasing. With existing stabilizers, when using a mobile phone to shoot horizontally, the communication interface of the mobile phone is often blocked by the motor and cannot be used; when using a mobile phone to shoot vertically, the mobile phone often collides with the navigation motor located below it, resulting in a small range of movement and shooting range of the mobile phone during shooting. At present, the problem of collision between the mobile phone and the navigation motor during vertical shooting is mainly solved by increasing the length of the vertical connecting arm, so that the mobile phone has a larger range of movement during shooting; but at the same time, it also makes the size of the stabilizer larger, which is not easy to store, affects the experience effect, and increases the cost.

[0003] In the prior art, Chinese patent CN109707981A discloses a handheld three-axis stabilizer, comprising a handle; a panning-axis motor located at the top of the handle; a roll-axis motor located above the panning-axis motor, the roll-axis motor being connected to the panning-axis motor via a first connecting arm; a pitch-axis motor located above the panning-axis motor, the pitch-axis motor being connected to the roll-axis motor via a second connecting arm; a clamp, the clamp being connected to the top surface of the pitch-axis motor via a clamp adjustment device to allow the clamp to be spatially displaced relative to the pitch-axis motor, wherein the clamp adjustment device comprises: a support arm extending from the top surface of the pitch-axis motor, wherein the extension direction of the support arm forms an acute angle with respect to the pivot axis of the pitch-axis motor; a clamp seat fixedly connected to the clamp; and a center of gravity adjustment mechanism arranged between the support arm and the clamp seat, which is configured to adjust the spacing between the clamp seat and the support arm. The above-mentioned handheld three-axis stabilizer adopts a support arm extending from the top surface of the pitch axis motor and the distance between the support arm and the clamp is adjustable, so as to allow the clamp to be positioned spatially offset relative to the pitch axis motor, thereby overcoming the problem that the data cable interface of the shooting equipment is blocked by the pitch motor during shooting and the mobile phone accidentally collides with the motor on the stabilizer.

[0004] However, the above-mentioned three-axis stabilizer can only adjust the distance between the clamp and the support arm, and the clamp cannot slide along the length direction of the support arm. When in use, it is inconvenient to adjust the camera equipment on the clamp to a suitable installation position, which affects the user experience of the stabilizer; in the storage state, the clamp cannot be adjusted to the minimum storage position, which will occupy a larger storage space and is not convenient for storage and carrying.

During the process of installing the shooting device on the clamp seat, especially in the process of installing it on the clamp seat in a horizontal manner, the shooting device is not prone to accidental collision with the motor on the pan-tilt assembly, so that the installation of the shooting equipment on the clamp seat is more convenient and the use experience of the handheld stabilizer is improved; before storage, the clamp seat and the sliding seat are slid to the end of the support arm close to the pan-tilt assembly, which can reduce the size of the space occupied by the pan-tilt assembly and the clamp seat as a whole. After the pan-tilt assembly is folded, the storage space required for the handheld stabilizer as a whole is smaller, and the portability is higher.

[0035] 2. The clamp seat adjustment device of the handheld stabilizer provided by the present invention, in which the sliding seat and the support arm are locked or unlocked by a locking assembly, can adjust the clamp seat connected to the sliding seat to any horizontal position of the support arm, thereby facilitating the adjustment of the camera equipment on the clamp seat to the optimal shooting position, making the use of the handheld stabilizer more convenient.

[0036] 3.

On the one hand, it is convenient to install the slider of the sliding seat on the support arm in any direction; on the other hand, the notch structures on the other two side edges of the sliding seat relative to the first notch and the second notch can be engaged with the limiting structures on the two end portions in the length direction of the support arm. Since the gimbal assembly is in the storage state, the sliding seat needs to slide to one end of the support arm close to the gimbal assembly. At this time, the notch structure on the sliding seat is engaged with the limiting structure at the end of the support arm, which can improve the stability of the handheld stabilizer in the storage state.

[0043] 10. The clamp seat adjustment device of the handheld stabilizer provided by the present invention has a clamp seat and a sliding seat fixedly connected by fasteners, and the installation structure has higher stability; and the elastic pad arranged between the fastener and the bottom of the installation hole will generate a continuous elastic force to prevent the fastener from loosening.

[0044] 11. The clamping seat adjustment device of the handheld stabilizer provided by the present invention, the boss structure on the sliding seat and the groove structure on the clamping seat cooperate with each other in a manner that can prevent the clamping seat from rotating relative to the sliding seat, thereby ensuring the position stability of the shooting device on the clamping seat.

[0046] 13. The handheld stabilizer provided by the present invention has an adjustable horizontal position of the clamp seat relative to the support arm when the gimbal assembly is in the storage state. When the gimbal assembly is in the storage state, the clamp seat slides to the end of the support arm close to one end of the gimbal assembly. After the gimbal assembly is folded, the clamp seat is located in the storage space formed by the handle assembly, the first connecting arm, the second connecting arm and the support arm. After the handheld stabilizer is folded, the overall storage space occupied by the handheld stabilizer is smaller, thereby improving the portability of the handheld stabilizer.

DETAILED DESCRIPTION

[0058] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0060] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] like Figure 1 and Figure 2 A handheld stabilizer shown includes a handle assembly 1, a gimbal assembly 2, a clamp seat 4, and a clamp seat adjustment device connected between the gimbal assembly 2 and the clamp seat 4, the gimbal assembly 2 is connected to the handle assembly 1, and the clamp seat 4 is used to clamp the shooting equipment. Specifically, the handle assembly 1 is in the shape of an upright long axis. The handle assembly 1 has a cavity for accommodating a battery and function keys arranged on the outer surface of the handle assembly 1, and the above-mentioned function keys include but are not limited to a multi-directional operating button, an indicator light, and a mode selection dial. A control circuit for realizing the stabilization function of the stabilizer is arranged inside the handle assembly 1. Furthermore, in order to improve the user's experience when holding the handle, the handle assembly 1 has an ergonomic curved portion on its exterior.

[0063] In this embodiment, the pan-tilt assembly 2 includes a pan-axis motor 21 disposed at the top of the handle assembly 1 for driving the camera device carried by the handheld stabilizer to move in the pan direction. The pan-axis motor 21 exemplarily has a pivot axis coaxial with the longitudinal axis of the handle assembly 1. Of course, this design is not restrictive. In order to expand the range of movement and shooting range of the camera device, it is also feasible to make the pivot axis Y axis of the pan-axis motor 21 not coaxial with the longitudinal axis of the handle assembly 1. The pan-tilt assembly 2 also includes a roll-axis motor 22 rotatably connected to one end of the pan-axis motor 21 relative to the handle assembly 1 through a first connecting arm 23. The roll-axis motor 22 is used to drive the camera device carried by the handheld stabilizer to move in its roll direction. The first connecting arm 23 is configured to extend from the pan-axis motor 21 to the roll-axis motor 22 at a certain angle (for example, but not limited to 45 to 55 degrees) outwardly to the roll-axis motor 22 so that the roll-axis motor 22 is in a tilted posture, that is, the pivot axis of the roll-axis motor 22 forms a first acute angle with the pivot axis of the pan-axis motor 21. At the same time, the gimbal assembly 2 also has a pitch-axis motor 24 located above the pan-axis motor 21 and used to drive the carried shooting equipment to move in its pitch direction. The pitch-axis motor 24 is connected to one end of the roll-axis motor 22 relative to the first connecting arm 23 via a second connecting arm 25; wherein the second connecting arm 25 is exemplarily constructed to extend outward from the roll-axis motor 22 at a certain angle (for example but not limited to 45 to 55 degrees) to the pitch-axis motor 24 so that the pitch-axis motor 24 is in a tilted posture, that is, the pivot axis of the pitch-axis motor 24 and the pivot axis of the roll-axis motor 22 form a second acute angle.

[0064] In this embodiment, the gimbal assembly 2 has an unfolded state and a retracted state during the rotation of the clamp seat 4 relative to the handle assembly 1; when the gimbal assembly 2 is in the unfolded state, the first connecting arm 23 extends obliquely upward from the top of the pan axis motor 21, and the second connecting arm 25 also extends obliquely upward from the top of the roll axis motor 22, and the clamp seat 4 is connected to the gimbal assembly 2 through the support arm 3 laterally connected to the output shaft of the pitch axis motor 24, and the clamp seat 4 is located above the handle assembly 1; an angle is formed between the first connecting arm 23 and the second connecting arm 25; when the gimbal assembly 2 is in the unfolded state, the first connecting arm 23 and the second connecting arm 25 extend ... second connecting arm 25 extends obliquely upward from the top of the roll axis motor 22. When the platform assembly 2 changes from the unfolded state to the stored state, the pitch axis motor 24 drives the support arm 3 to rotate a certain angle, and the roll axis motor 22 drives the second connecting arm 25 to rotate a certain angle, so that the connecting arm, the second connecting arm 25 and the first connecting arm 23 are basically on the same straight line, and then the pan axis motor 21 drives the first connecting arm 23 to flip around its pivot axis toward the top of the handle assembly 1, so that the handle assembly 1, the first connecting arm 23, the second connecting arm 25 and the support arm 3 are surrounded to form a storage space, and the clamp seat 4 connected to the support arm 3 is located in the storage space. Further, the clamp seat 4 has a pair of clamping arms that are arranged oppositely and have a storage space for accommodating the shooting equipment; when the pan / tilt assembly 2 is in the stored state, the connecting direction of the two clamping arms on the clamp seat 4 is perpendicular to the axial direction of the handle assembly 1, so that the storage space on the clamp seat 4 matches the arc portion on the handle assembly 1, which is conducive to reducing the overall size of the handheld stabilizer in the stored state and reducing the production and manufacturing cost of the handheld stabilizer.

[0065] In order to reduce the possibility that the bottom of the shooting device on the clamp 4 is blocked or even interfered by the pitch-axis motor 24 when the shooting device is performing pitch and roll movements, it is generally necessary to connect a support arm 3 extending outward by a certain length to the output shaft of the pitch-axis motor 24 of the gimbal assembly 2, and install the clamp 4 as far as possible at the end of the support arm 3 away from the pitch-axis motor 24; in this way, since the clamp 4 is connected to the end of the support arm 3 opposite to the gimbal assembly 2, the size of the handheld stabilizer in the stored state will inevitably increase to a certain extent, and therefore there is still the problem of a large storage size and inconvenience in carrying. In order to solve the above problems, an embodiment of the present invention is provided with a clamp seat adjustment device between the clamp seat 4 and the gimbal assembly 2. When the gimbal assembly 2 is in the unfolded state, the clamp seat adjustment device adjusts the clamp seat 4 to the end away from the pitch axis motor 24 to allow the clamp seat 4 to be spatially displaced relative to the pitch axis motor 24, thereby overcoming the problem that the data cable interface of the shooting equipment is blocked by the pitch motor during shooting and the mobile phone and the motor on the stabilizer accidentally collide with each other; when the gimbal assembly 2 is in the stored state, the clamp seat adjustment device adjusts the clamp seat 4 to the end close to the pitch axis motor 24, so that the second connecting arm 25 and the support arm 3 can be closer to the handle assembly 1 when folded, thereby reducing the size of the storage space enclosed by the handle assembly 1, the first connecting arm 23, the second connecting arm 25 and the support arm 3, so that the clamp seat 4 is in the smallest storage position, reducing the size of the space occupied when stored for handheld stability, and having higher portability.

[0066] like Figure 3 -9, the clamp seat adjustment device of the present invention will be further described in detail below. The clamp seat adjustment device is connected between the clamp seat 4 and the foldable pan-tilt assembly 2, and includes a support arm 3 extending outward from the output axis of the pitch axis motor 24, and a sliding seat 5 slidably mounted on the support arm 3 and connected to the clamp seat 4; the sliding seat 5 slides back and forth between a first position close to the pan-tilt assembly 2 and a second position away from the pan-tilt assembly 2. The sliding seat 5 can slide back and forth on the support arm 3 to get closer to or away from the pan-tilt assembly 2; when in use, the pan-tilt assembly 2 is unfolded, and then the clamp seat 4 and the sliding seat 5 are slid to the end of the support arm 3 away from the pan-tilt assembly 2, which is convenient for installing the shooting device on the clamp seat 4. During the process of installing the shooting device on the clamp seat 4, especially when it is installed on the clamp seat 4 in a horizontal manner, the shooting device is not prone to accidental collision with the motor on the pan-tilt assembly 2, making the installation of the shooting equipment on the clamp seat 4 more convenient and improving the user experience of the handheld stabilizer; before storage, the clamp seat 4 and the sliding seat 5 are slid to the end of the support arm 3 close to the pan-tilt assembly 2, which can reduce the overall space occupied by the pan-tilt assembly 2 and the clamp seat 4. After the pan-tilt assembly 2 is folded, the overall storage space required for the handheld stabilizer is smaller, and the portability is higher.

[0067] In this embodiment, the clamping seat adjustment device also includes a locking assembly 6 movably mounted on the support arm 3, and the locking assembly 6 has a locking state for locking the relative position of the sliding seat 5 and the support arm 3, and an unlocking state for releasing the relative position of the sliding seat 5 and the support arm 3. The sliding seat 5 and the support arm 3 are locked or unlocked by the locking assembly 6, so that the clamping seat 4 connected to the sliding seat 5 can be adjusted to any horizontal position of the support arm 3, so as to facilitate the adjustment of the camera equipment on the clamping seat 4 to the best shooting position, making the use of the handheld stabilizer more convenient. In some other embodiments, the locking assembly 6 may not be provided, and the clamping seat 4 connected to the sliding seat 5 can be adjusted to any horizontal position of the support arm 3 by relying on the damping force between the sliding seat 5 and the support arm 3, and the damping force can be overcome by external force during adjustment.

[0068] Furthermore, the sliding seat 5 includes a main body 51 connected to the clamping seat 4, and a slider 52 connected to one end of the main body 51 near the support arm 3, and a positioning block 31 is provided on the support arm 3 against which one end of the slider 52 abuts; the locking assembly 6 includes a locking block 61 and a driving structure, wherein the locking block 61 is located at one end of the slider 52 relative to the positioning block 31, and cooperates with the positioning block 31 to form a sliding space 32 for the slider 52 to slide, and the locking block 61 has a locking position close to the positioning block 31 to cooperate with the positioning block 31 to clamp the slider 52 and an unlocking position away from the positioning block 31 to release the slider 52; the driving structure is movably installed on the support arm 3, and drives the locking block 61 to reciprocate between the locking position and the unlocking position. The driving structure is used to drive the locking block 61 to approach the positioning block 31 to cooperate with the positioning block 31 to clamp the sliding seat 5 or to move away from the positioning block 31 to release the sliding seat 5 to achieve the locking and unlocking of the sliding seat 5, which has the advantages of simple structure and convenient operation.

[0069] In this embodiment, the driving structure includes a connecting rod 63, a driving member 62 and an elastic member 64; wherein the connecting rod 63 is installed on the support arm 3 and passes through the locking block 61, and has an external thread; the driving member 62 is threadedly connected to the external thread of the connecting rod 63, and rotates around the connecting rod 63 under the action of an external force to drive the locking block 61 to move from the unlocking position to the locking position along the axial direction of the connecting rod 63; the elastic member 64 is located between the locking block 61 and the support arm 3, and its elastic force drives the locking block 61 to move from the locking position to the unlocking position. Specifically, the connecting rod 63 is a locking screw fixed on the support arm 3 and having an external thread on the part extending out of the support arm 3, the driving member 62 is a knob cap threadedly connected to the locking screw, and the elastic member 64 is specifically a spring. The driving member 62 is threadedly connected to the connecting rod 63, and the locking block 61 is movably connected to the outer periphery of the connecting rod 63, so that the rotational movement of the driving member 62 can be converted into the linear movement of the locking block 61 along the axial direction of the connecting rod 63; this driving structure has a simple structure, occupies a small space, and is convenient for loosening or locking the sliding seat 5; at the same time, an elastic member 64 is arranged between the locking block 61 and the support arm 3, and the force exerted by the elastic member 64 on the locking block 61 is opposite to the direction of the force exerted by the driving member 62 on the locking block 61, which can avoid the false locking phenomenon of the locking block 61, thereby improving the stability of the sliding seat 5 in the locked state, and then improving the stability of the clamping seat 4, thereby ensuring the shooting effect of the shooting device on the clamping seat 4.

[0070] Furthermore, the elastic member 64 includes two springs symmetrically arranged on opposite sides of the locking block 61 along the axial direction of the connecting rod 63. The two springs symmetrically arranged on opposite sides of the locking block 61 are used as the elastic member 64, so that the elastic force on each part of the locking block 61 is more uniform, and the locking block 61 is not prone to deflection during movement, thereby improving the stability of the locking assembly 6.

[0071] Specifically, the support arm 3 is provided with a positioning hole 33 with an opening toward the locking block 61, and the opposite ends of the locking block 61 are respectively provided with positioning posts 611 that can be inserted into the positioning holes 33, and two springs are placed in the positioning holes 33 and respectively abut against the corresponding positioning posts 611. The positioning posts 611 on the locking block 61 are inserted into the positioning holes 33 on the support arm 3, and the positioning holes 33 guide the movement of the positioning posts 611 and the locking block 61, thereby improving the stability of the locking block 61 during movement.

[0072] In this embodiment, a first notch 531 is formed at a connection portion between the slider 52 and the main body 51 on a side close to the positioning block 31, and a first clamp 311 is provided on the positioning block 31 to be embedded in the first notch 531. A second notch 532 is also formed at a connection portion between the slider 52 and the main body 51 on a side opposite to the first notch 531, and a second clamp 612 is provided on the locking block 61 to be embedded in the second notch 532. The structure in which the first clamp 311 on the positioning block 31 is embedded in the first notch 531 on the sliding seat 5 and the structure in which the second clamp 612 on the locking block 61 is embedded in the second notch 532 on the sliding seat 5 can prevent the slider 52 of the sliding seat 5 from sliding off from the sliding space 32 formed by the support arm 3 and the locking block 61, thereby improving the stability of the installation structure of the sliding seat 5.

[0073] In a preferred implementation of the present embodiment, the slider 52 is a regular tetrahedral structure, and a notch structure 53 that can be snap-fitted with the positioning block 31 or the locking block 61 is formed between the four sides of the slider 52 and the main body 51. At this time, the first notch 531 and the second notch 532 are part of the notch structure 53 and are arranged opposite to each other. On the one hand, the slider 52 of the regular tetrahedral structure is convenient for installing the slider 52 of the sliding seat 5 on the support arm 3 in any direction; on the other hand, the notch structure 53 on the other two side edges of the sliding seat 5 relative to the first notch 531 and the second notch 532 can be engaged with the limiting structures on the two ends of the support arm 3 in the length direction, and because when the pan-tilt assembly 2 is in the storage state, the sliding seat 5 needs to slide to one end of the support arm 3 close to the pan-tilt assembly 2, at this time, the notch structure 53 on the sliding seat 5 is engaged with the limiting structure at the end of the support arm 3, which can improve the stability of the handheld stabilizer in the storage state.

[0074] In this embodiment, a mounting hole is provided on the sliding seat 5, and the sliding seat 5 is connected to the clamping seat 4 through a fastener 7 that is fixedly connected to the clamping seat 4 and penetrates the mounting hole, and an elastic pad is sleeved on the outer periphery of the fastener 7 and is padded between the bottom of the mounting hole and the fastener 7. Specifically, the fastener 7 can be a fastening screw, and the elastic pad includes four flat washers 8 and an elastic washer 9. The clamping seat 4 and the sliding seat 5 are fixedly connected by the fastener 7, and the mounting structure is more stable; and the elastic pad padded between the fastener 7 and the bottom of the mounting hole will generate a continuous elastic force, which can prevent the fastener 7 from loosening.

[0075] In this embodiment, a boss structure is provided on one side of the sliding seat 5 close to the clamping seat 4, and a groove structure matching the shape of the boss structure is provided on the clamping seat 4, and the mating surfaces of the boss structure and the groove structure are arc-shaped surfaces. In other embodiments, the boss structure can also be provided on the clamping seat 4, and the groove structure can also be provided on the sliding seat 5. The boss structure on the sliding seat 5 and the groove structure on the clamping seat 4 cooperate with each other to prevent the clamping seat 4 from easily rotating relative to the sliding seat 5, thereby ensuring the position stability of the shooting device on the clamping seat 4.

[0076] Specifically, the groove structure includes four strip-shaped positioning grooves 41 arranged in a cross-symmetric manner, and the boss structure includes four strip-shaped positioning bosses arranged in a cross-symmetric manner and matched one by one with the four strip-shaped positioning grooves 41; the length directions of two opposing strip-shaped positioning grooves 41 are the same, and the length directions of two adjacent strip-shaped positioning grooves 41 are perpendicular; the length directions of two opposing strip-shaped positioning bosses are the same; and the length directions of two adjacent strip-shaped positioning bosses are perpendicular. With the four strip-shaped positioning grooves 41 and four strip-shaped positioning bosses arranged in a cross-symmetric manner, after the clamping seat 4 rotates 90 degrees relative to the sliding seat 5, the four strip-shaped positioning bosses on the clamping seat 4 can still be positioned and matched one by one with the four strip-shaped positioning grooves 41 on the sliding seat 5, so as to facilitate the horizontal and vertical shooting switching of the clamping seat 4.

[0077] In summary, the clamp seat adjustment device and the handheld stabilizer provided by the embodiments of the present invention, by setting a sliding seat 5 that can slide back and forth on the support arm 3 between the clamp seat 4 and the support arm 3, the sliding seat 5 slides back and forth between a first position close to the gimbal assembly 2 and a second position away from the gimbal assembly 2; when in use, the gimbal assembly 2 is unfolded, and then the clamp seat 4 and the sliding seat 5 are slid to the end of the support arm 3 away from the gimbal assembly 2, so as to facilitate the installation of the shooting device on the clamp seat 4. During the installation of the shooting device on the clamp seat 4, especially during the installation on the clamp seat 4 in a horizontal manner, the shooting device is not prone to accidental collision with the motor on the gimbal assembly 2, so that the installation of the shooting device on the clamp seat 4 is more convenient, and the use experience of the handheld stabilizer is improved; before storage, the clamp seat 4 and the sliding seat 5 are slid to the end of the support arm 3 close to the gimbal assembly 2, so as to reduce the size of the space occupied by the gimbal assembly 2 and the clamp seat 4 as a whole. After the gimbal assembly 2 is folded, the storage space required for the handheld stabilizer as a whole is smaller, and the portability is higher.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
