The present disclosure relates to the field of a gimbal device, and specifically relates to a handheld gimbal.
Taking pictures and photography with mobile phones has become a popular hobby. In order to be able to shoot stable and smooth images, it is often necessary to use a handheld gimbal. In a traditional foldable gimbal, in addition to a necessary stabilization axis, an additional folding shaft is required to switch the gimbal from an unfolded state to a folded, storage state. The externally arranged folding shaft increases overall volume of the handheld gimbal, increases weight of the handheld gimbal, and also has a certain negative impact on reliability and stability of the gimbal.
One example of the present disclosure provides a handheld gimbal. The handheld gimbal may include a handle having a top, a bottom, and a side wall between the top and the bottom; a first shaft assembly including a first rotating shaft provided at the top of the handle, a first shaft motor for driving the first rotating shaft, and a first connecting arm connected with the first rotating shaft; a second shaft assembly including a second rotating shaft, a second shaft motor for driving the second rotating shaft, and a second connecting arm connected to the second rotating shaft; a third shaft assembly including a third rotating shaft and a third shaft motor for driving the third rotating shaft, the third rotating shaft being provided at an end of the second connecting arm away from the second rotating shaft; and a bearing portion connected with the third shaft assembly and configured to carry a shooting equipment. An axial direction of the second rotating shaft may be perpendicular to an extending direction of the second connecting arm. When the handheld gimbal is in a usage state, one or more of the first shaft motor, the second shaft motor, and the third shaft motor may be configured to provide driving force to adjust spatial position of the bearing portion. When the handheld gimbal is changed from the usage state to a storage state to a folded state, the second shaft motor may be configured to provide driving force to rotate the second connecting arm to fold the handheld gimbal, and both the first rotating shaft and the third rotating shaft may be located on a same side of the second rotating shaft after the handheld gimbal is folded.
In order to explain technical features of embodiments of the present disclosure more clearly, drawings used in the present disclosure are briefly introduced as follow. Obviously, the drawings in the following description are some exemplary embodiments of the present disclosure. Ordinary person skilled in the art may obtain other drawings and features based on these disclosed drawings without creative work.
In order to make objectives, technical solutions, and advantages of embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within protection scope of the present disclosure. In the case of no conflict, the following embodiments and features in the embodiments may be recombined with one another.
In the following description, many specific details are set forth in order to fully understand this disclosure. However, this disclosure can also be implemented in other ways different from those described here. Therefore, the protection scope of the present disclosure is not limited by the specific embodiments disclosed below.
Hereinafter, the handheld gimbal according to some embodiments of the present disclosure will be described with reference to
As shown in
This embodiment of the present disclosure provides a three-shaft handheld gimbal, which can realize pitch movement of the second connecting arm 18 controlled by the second shaft motor in the non-usage state so as to realize folding of the handheld gimbal. This configuration may save space for holding the handheld gimbal when the handheld gimbal is not in use. When it is required to use the handheld gimbal, the second connecting arm 18 is controlled to rotate to open the handheld gimbal through the second shaft motor, and the three-shaft handheld gimbal can be used normally. This configuration can realize the folding of the handheld gimbal in the non-usage state while realizing function of rotating the handheld gimbal around three axes. Because the tilt shaft is reused for the gimbal folding, there is no need to add unnecessary folding shafts to assist the rotation of the handheld gimbal. It can also enhance overall stability of the handheld gimbal and eliminate influence of non-essential factors on the stability of the handheld gimbal, thereby facilitating carrying of the handheld gimbal, reducing the space required for storing the handheld gimbal, and facilitating storage.
Optionally, the handheld gimbal includes a handle 10, a first rotating shaft 12, a second rotating shaft 16 and a third rotating shaft 20, wherein the axial direction of the second rotating shaft 16 is perpendicular to the extending direction of the second connecting arm 18. That is, the second connecting arm 18 is capable of pitching movement. When the handheld gimbal is in use, it can provide driving force through any one or more of the first shaft motor, the second shaft motor and the third shaft motor to adjust spatial position of the bearing portion. The position of the bearing portion in the space can be adjusted accurately, and the stability of the shooting equipment such as mobile phones and cameras placed on the bearing portion can be increased. When the handheld gimbal is changed from the usage state to the storage state as shown in
Optionally, the first shaft motor can drive the first rotating shaft 12 as a whole or partially to rotate to drive the first connecting arm 14 to rotate. The second shaft motor can drive the second rotating shaft 16 as a whole or partially to rotate to drive the second connecting arm 18 to rotate. The third shaft motor can drive the third rotating shaft 20 as a whole or partially to rotate to drive the bearing portion 22 to rotate.
In some embodiments, the first rotating shaft 12 includes a first housing fixedly connected to the handle and a first shaft arranged in the first housing. The first shaft motor drives the first shaft to rotate to drive the first connecting arm to rotate. At this time, the first shaft motor drives the first rotating shaft 12 partially to rotate.
In other embodiments, the first rotating shaft 12 is fixedly connected or movably connected to the first connecting arm 14, and the first shaft motor directly drives the first rotating shaft 12 to rotate to drive the first connecting arm to rotate. At this time, the first shaft motor drives the first rotating shaft 12 as a whole to rotate.
In some embodiments, the third rotating shaft 20 includes a third housing fixedly connected to the second connecting arm 18 and a third shaft provided in the third housing. The third shaft motor drives the third shaft to rotate to drive the bearing portion 22 to rotate. At this time, the third shaft motor drives the third rotating shaft 20 partially to rotate.
In other embodiments, the third rotating shaft 20 is movably connected to the second connecting arm 18, and the third shaft motor directly drives the third rotating shaft 20 to rotate so as to drive the bearing portion 22 to rotate. At this time, the third shaft motor drives the third rotating shaft 20 as a whole to rotate.
In some embodiments, the second connecting arm 18 and the second rotating shaft 16 are integrally formed. At this time, the second shaft motor can drive the second rotating shaft 16 as a whole to rotate.
In some embodiments, as shown in
In some embodiments, when the handheld gimbal is changed from the usage state to the storage state, after the folding of the handheld gimbal, the bearing portion 22 is located on the side of the second connecting arm 18 away from the handle 10. That is, the second connecting arm 18 is located between the bearing portion 22 and the handle 10. Such design can avoid the situation in which it is difficult to sandwich the bearing portion 22 between the second connecting arm 18 and the handle 10 due to the large volume of the bearing portion 22. Moreover, it is beneficial to fold the shooting equipment placed on the bearing portion 22 together with the bearing portion 22 on the side of the second connecting arm 18 away from the handle 10, which facilitates the folding of the handheld gimbal in the non-usage state during shooting without disassembling the shooting equipment.
In some embodiments, the bearing portion 22 is provided with a buckling portion, and the buckling portion can be buckled with the handle 10 when the handheld gimbal is changed from the usage state to the storage state. This is helpful for the handheld gimbal to maintain the folded state stably.
In some embodiments, as shown in
In some embodiments, the bearing portion 22 includes a damper or a clamping mechanism, which is conducive to stably clamping the shooting equipment. Of course, the bearing portion 22 may not include a clamper or a clamping mechanism, and the shooting equipment can be directly placed on the position defined by the bearing portion 22.
In some embodiments, as shown in
In some embodiments, as shown in
In this embodiment, when the handheld gimbal is changed from the usage state to the folded state, if the two clamping ears 222 are spaced apart along the length direction of the handle 10, it is helpful for the handheld gimbal to stably hold the shooting equipment in the usage state and avoid the shooting equipment being dropped. If the two clamping ears 222 are spaced apart in a direction perpendicular to the length direction of the handle 10, it is beneficial to avoid the handle 10 after folding.
In some embodiments, the first shaft motor can drive the first connecting arm 14 to make a yaw movement relative to the handle 10, thereby realizing automatic yaw motion function of the handheld gimbal.
In some embodiments, the second shaft motor can drive the second connecting arm 18 to make a pitch movement relative to the first connecting arm 14, thereby realizing automatic pitch motion function of the handheld gimbal.
In some embodiments, the third shaft motor can drive the bearing portion 22 to roll, thereby realizing automatic roll motion function of the handheld gimbal.
In some embodiments, the rotating axis of the first rotating shaft and the rotating axis of the second rotating shaft intersect perpendicularly in the first projection plane, and the rotating axis of the second rotating shaft and the rotating axis of the third rotating shaft intersect perpendicularly in the second projection plane. Wherein, the first projection plane is a projection plane in a side view direction of the handheld gimbal, and the second projection plane is a projection plane in a top view direction of the handheld gimbal. Such configuration is helpful for the handheld gimbal to realize yaw, pitch and roll movements, thereby realizing multi-angle movement of the bear portion in the space.
Optionally, the first projection plane is any projection plane in the side view direction of the handheld gimbal. Even if the rotating axis of the second rotating shaft projects as only one point in a projection plane of a certain angle, it is determined that the rotating axis of the first rotating shaft and the rotating axis of the second rotating shaft intersect perpendicularly within the projection plane. Similarly, the second projection plane is any projection plane in the top view direction of the handheld gimbal. Even if the rotating axis of the third rotating shaft projects as only one point when the handheld gimbal is in a certain posture, it is also determined that the rotating axis of the second rotating shaft and the rotating axis of the third rotating shaft intersect perpendicularly within the projection plane.
It should be noted that, in this disclosure, the direction viewed from the top to the bottom of the handle 10 is the top view direction of the handheld gimbal, and the direction of looking squarely at the side wall of the handle 10 is the side view direction of the handheld gimbal.
In some embodiments, when the handheld gimbal is in use, the second rotating shaft is closer to the handle 10 than the third rotating shaft. When the handheld gimbal is changed from the usage state to the storage state, after the folding of the handheld gimbal, the third rotating shaft is closer to the handle 10 than the second rotating shaft.
In this embodiment, since the handle 10, the first shaft motor, the second shaft motor, and the third shaft motor are connected in sequence, the middle connecting parts between the shaft motors such as the first connecting arm 14, the second connecting arm 18 and so on are omitted here. By setting that, when the handheld gimbal is in use, the second rotating shaft 16 is closer to the handle 10 than the third rotating shaft 20, that is, the third rotating shaft 20 is farther away from the handle 10, it is advantageous for the bearing portion 22 located at the free end to extend to a larger and farther space. By setting that, when the handheld gimbal is changed from the usage state to the storage state, the third rotating shaft 20 is closer to the handle 10 than the second rotating shaft 16 after folding, it is beneficial to reduce occupied space of the handheld gimbal after the folding, and is convenient for storage and portability.
Optionally, when the handheld gimbal is changed from the usage state to the storage state, after folding, the third rotating shaft 20 is close to the side wall or bottom of the handle 10, and the second rotating shaft 16 and the handle 10 are still separated at least by the first rotating shaft 12.
In some embodiments, when the handheld gimbal is in use, the third rotating shaft 20 is located at the top area of the handle 10. When the handheld gimbal is changed from the usage state to the storage state, after folding, the third rotating shaft 20 is close to the side wall of the handle 10 and located at one side of the handle 10, or the third rotating shaft 20 is located at the bottom area of the handle 10 after the folding.
Among them, the third rotating shaft being located at the top area of the handle 10 means that the third rotating shaft 20 extends beyond the top of the handle 10 in the length direction of the handle 10. The third rotating shaft protruding slightly beyond the top of the handle 10 is also considered as extending beyond the top of the handle. The third rotating shaft being located at the bottom area of the handle 10 means that the third rotating shaft extends beyond the bottom of the handle 10 in the length direction of the handle 10. The third rotating shaft 20 protruding slightly beyond the bottom of the handle 10 is also considered as extending beyond the bottom of the handle as well.
Optionally, when the folded third rotating shaft is located at the bottom area of the handle 10, the length of the second connecting arm 18 is longer than the handle 10, and further, the second connecting arm 18 is an L-shaped arm or a -shaped arm.
In some embodiments, as shown in
In some embodiments, as shown in
In this embodiment, by setting the first connecting arm 14 including two connecting ears 142 distributed at intervals, and the second rotating shaft 16 being partially extended into a space between the two connecting ears 142 and rotatably connected with the two connecting ears 142, the rotation connection with the first connecting arm 14 is realized. The connection is stable and reliable, and the space between the two connecting ears 142 also provides an avoidance space for the pitch movement of the second connecting arm 18.
Optionally, as shown in
In some embodiments, the first connecting arm 14 is disposed at the top of the first rotating shaft 12, and the rotating center line of the first connecting arm 14 overlaps with the rotating axis of the first rotating shaft 12.
Optionally, as shown in
In some embodiments, as shown in
In some embodiments, as shown in
In some embodiments, the second connecting arm 18 extends along the tangential direction of the second rotating shaft 16.
Optionally, as shown in
Optionally, the rotating axis of the second rotating shaft 16 overlaps with its own center line, That is, the rotating axis of the second rotating shaft intersects with a surface of the second rotating shaft at a center of the second rotating shaft. Optionally the second connecting arm 18 is configured as an L-shaped arm. At this time, it is sufficient that the second connecting arm 18 is substantially L-shaped, which is advantageous for the long arm part of the second connecting arm 18 to be close to the handle 10 after folding.
In some embodiments, the axial direction of the first rotating shaft 12, the axial direction of the second rotating shaft 16 and the axial direction of the third rotating shaft 20 are perpendicular to one another in pairs.
In some embodiments, the extending direction of the first connecting arm is aligned with the axial direction of the first rotating shaft. During the yaw movement of the first connecting arm, the center of gravity of the first connecting arm can completely fall on the first rotating shaft, or even on the rotating axis of the first rotating shaft, so as to ensure operating stability of the handheld gimbal.
In some embodiments, as shown in
Optionally, taking the direction of the control panel 24 as the front of the handle 10, the second connecting arm 18 can perform a pitch movement backward, or it can perform a pitch movement forward and/or a pitch movement backward.
In some embodiments, the handheld gimbal further includes a battery (not shown in the figure), which is arranged inside the handle 10.
Hereinafter, referring to
As shown in
Optionally, the specific folding step is that the second shaft motor controls the rotation of the second rotating shaft 16 so that the second connecting arm 18 performs a top view or pitch movement until it moves to one side of the handle 10. As shown in
