Abstract

A holder adjustment device for a handheld gimbal stabilizer is connected between a holder (4) and a collapsible stabilization assembly (2), and comprises: a support arm (3) extending outward from a top portion of the stabilization assembly; and a sliding base (5) slidably installed at the support arm and connected to the holder. The sliding base can slidably reciprocate between a first position close to the stabilization assembly and a second position away from the stabilization assembly. Also disclosed is a handheld gimbal stabilizer. During use, the holder and the sliding base are slid to an end of the support arm away from the stabilization assembly, such that a motor on the stabilization assembly does not accidentally impact an image capturing device, thereby facilitating mounting of the image capturing device on the holder, and improving use experience of the handheld gimbal stabilizer. For storage, the holder and the sliding base are slid to an end of the support arm close to the stabilization assembly to reduce the overall space occupied by the stabilization assembly and the holder. After the stabilization assembly is collapsed, the handheld gimbal stabilizer requires a reduced overall accommodation space, thereby enhancing portability.

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

A hand-held stabilizer as shown in Figures 1 and 2, including a handle assembly 1, a pan/tilt assembly 2, a clamping base 4, and a clamping base adjusting device connected between the pan/tilt assembly 2 and the clamping base 4. The pan/tilt The assembly 2 is connected to the handle assembly 1, and the clamp base 4 is used to clamp the shooting device. Specifically, the handle assembly 1 is in the shape of an upright long axis. The handle assembly 1 has a cavity for accommodating the battery and function keys arranged on the outer surface of the handle assembly 1. The above-mentioned function keys include, but are not limited to, multi-directional operation buttons, indicator lights, and mode selection dials. The handle assembly 1 is provided with a control circuit for realizing the stabilization function of the stabilizer. Further, in order to improve the user experience when holding it, the handle assembly 1 has an ergonomic curved part on its outer surface.

In this embodiment, the pan/tilt assembly 2 includes a yaw axis motor 21 arranged on the top of the handle assembly 1 for driving the shooting device mounted on the handheld stabilizer to move in the yaw direction. The yaw axis motor 21 exemplarily has the same The longitudinal axis of the handle assembly 1 is a coaxial pivot axis. Of course, this design is not limited. In order to expand the range of motion and shooting range of the shooting device, the pivot axis Y axis of the panning axis motor 21 is not aligned with the handle assembly. It is also feasible that the longitudinal axis of 1 is coaxial. The pan/tilt assembly 2 also includes a roll axis motor 22 rotatably connected to the end of the pan axis motor 21 opposite to the handle assembly 1 through the first connecting arm 23. The roll axis motor 22 is used to drive the mounted camera in its rolling direction. When moving upward, the first connecting arm 23 is configured to incline outward from the yaw axis motor 21 to a certain angle (for example, but not limited to 45 to 55 degrees) and extend to the roll axis motor 22 so that the roll axis motor 22 is in an inclined posture, That is to say, the pivot axis of the roll axis motor 22 and the pivot axis of the yaw axis motor 21 form a first angle of acute angle. At the same time, the pan/tilt assembly 2 also has a tilt axis motor 24 located above the pan axis motor 21 for driving the mounted camera equipment to move in its tilt direction. The tilt axis motor 24 is connected to the horizontal axis via a second connecting arm 25. One end of the roller motor 22 opposite to the first connecting arm 23; wherein the second connecting arm 25 is exemplarily configured to extend from the roller motor 22 to a certain angle (for example, but not limited to 45 to 55 degrees) inclined outwards The pitch axis motor 24 makes the pitch axis motor 24 in a tilt attitude, that is, makes the pivot axis of the pitch axis motor 24 and the pivot axis of the roll axis motor 22 become a second acute angle.

In this embodiment, the pan/tilt assembly 2 has an unfolded state and a storage state during the rotation of the holder 4 relative to the handle assembly 1; when the pan/tilt assembly 2 is in the unfolded state, the first connecting arm 23 is driven from the yaw axis motor 21 The top extends obliquely upward, and the second connecting arm 25 also extends obliquely upward from the top of the roll axis motor 22. The clamp base 4 is connected to the pan/tilt assembly 2 through a support arm 3 transversely connected to the output shaft of the pitch axis motor 24, and clamps The seat 4 is located at a position above the handle assembly 1; an angle is formed between the first connecting arm 23 and the second connecting arm 25; when the pan/tilt assembly 2 is transformed from the unfolded state to the stored state, the tilt axis motor 24 drives the support arm 3 Rotate a certain angle, 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 yaw axis motor 21 drives the first connection The arm 23 is turned over the handle assembly 1 about its pivot axis, so that the handle assembly 1, the first connecting arm 23, the second connecting arm 25 and the support arm 3 are enclosed to form a storage space, and the holder 4 connected to the support arm 3 Located in the storage space. Further, the clamping base 4 has a pair of oppositely arranged clamping arms with an accommodating space for accommodating the photographing equipment; when the pan-tilt assembly 2 is in the storage state, the two clamping arms on the clamping base 4 The connection direction is perpendicular to the axial direction of the handle assembly 1, so that the accommodating space on the clamp base 4 matches the curved portion on the handle assembly 1, thereby facilitating the reduction of the overall size of the handheld stabilizer in the stowed state and The production and manufacturing costs of the handheld stabilizer are reduced.

In order to reduce the possibility that the bottom of the shooting device is blocked or even interfered by the pitch axis motor 24 when the shooting device on the holder 4 is doing pitch and roll motions, it is generally necessary to connect the output shaft of the pitch axis motor 24 of the pan/tilt assembly 2 Extend the support arm 3 of a certain length outward, and install the clamp base 4 as far as possible on the end of the support arm 3 away from the pitch axis motor 24; in this way, since the clamp base 4 is connected to the support arm 3 relative to the pan/tilt assembly 2 One end will inevitably increase the size of the handheld stabilizer in the stowed state to a certain extent, so there is still a problem that the stowed size is too large and it is inconvenient to carry. In order to solve the above-mentioned problem, the embodiment of the present application is provided with a clamp base adjustment device between the clamp base 4 and the pan/tilt assembly 2. When the pan/tilt assembly 2 is in the unfolded state, the clamp base adjustment device adjusts the clamp base 4 away from the pitch axis One end of the motor 24 to allow the holder 4 to be displaced in space relative to the tilt axis motor 24, to overcome the data line interface of the shooting device being blocked by the tilt motor during the shooting process and the accidental bumping of the motor on the mobile phone and the stabilizer Problem: When the pan-tilt assembly 2 is in the storage state, the clamp base adjustment device adjusts the clamp base 4 to one 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 supporting arm 3, so that the clip base 4 is in the smallest storage position, and the space occupied by the stable storage of the handheld is reduced.
