Description

Multifunctional handheld electronic stabilizer

Technical Field

The utility model relates to the technical field of photography and shooting auxiliary equipment, in particular to a handheld electronic stabilizer.

Background

With the development of intelligent technology, photography (for example, photography using a camera or the like) is becoming a preference of many people, and the requirement of a photographer (operator) for a photographing effect is becoming higher and higher. In general, the operator can obtain a desired imaging effect in a stationary state. However, once the photographer is required to make a large amplitude exercise of walking, jumping, running, or the like in some occasions, the photographing effect is often unsatisfactory. The conventional handheld electronic stabilizer for assisting a camera device such as a stability-increasing mobile phone or a camera mostly adopts a three-axis stability-increasing cradle head to compensate for micro jitter in the shooting process.

Therefore, in the prior art, an electronic stabilizer is used as an auxiliary tool of a shooting device, the electronic stabilizer generally has at least two shafts, each shaft has a corresponding motor for driving and adjusting a rotation position, once a balance relation of a camera is damaged, a central processing unit analyzes signals fed back by sensors such as a gyroscope, an acceleration and a magnetic field in the stabilizer, and a correction signal is formed through a corresponding correction algorithm to control the motors to finally achieve an effect of correcting the balance position.

For example, in utility model patent application No. CN107255901A, a straight handle type camera stabilizer is proposed, which comprises a hand-held part 1, a fixed frame 4, a steering device 2 and a control device, which are connected in sequence from bottom to top, wherein a human-machine interface for a user to operate the control device is provided near the joint position of the connecting rod 21 of the hand-held part 1 and the fixed frame 4. Such a camera stabilizer can achieve a satisfactory stabilization effect, but since a heavy component (for example, a single lens reflex camera) carried by the camera stabilizer is located far above the hand of the user, the center of mass of the heavy component such as the single lens reflex camera will be located in front of the hand-held portion when the user is carrying the mirror accordingly. Further, since the handle of the stabilizer is designed to be straight, since a load of heaving motion of the heavy parts is applied to the user's hand holding the handle through the handle during the motion photographing of the hand-held stabilizer, which easily causes a relative displacement between the handle and the user's hand, the user is required to apply a greater gripping force to grip the stabilizer. As a result, the user has to make additional effort to hold the camera-mounted stabilizer in a fixed orientation, and using the hand-held camera stabilizer described above is both tiring and uncomfortable, which hinders the widespread use of the camera stabilizer. And the design of the stabilizer only has the use posture of vertical hand holding, the application scene is single, and the attraction to professional users with different use requirements is not strong.

As an attempt, a portable handheld stabilizer is proposed in utility model patent application with patent publication No. CN108799801A, can realize that both hands are held through adopting "7" style of calligraphy handle, and is laborsaving in the use of large-scale shooting equipment, improves user experience. Specifically, as shown in fig. 12 of the document, the handle 3 of the handheld stabilizer includes a first handle 31 and a second handle 32, two ends of the two handles are connected to form a 7-shaped structure, an included angle between the first handle 31 and the second handle 32 is 90 degrees, and a connecting end of the first handle 31 and the second handle 32 is connected to the heading motor 103; the handle in the shape of a Chinese character '7' can be held by two hands, and labor is saved in the using process of large-scale shooting equipment. However, if the load of the camera is too large during the use, the user still has the disadvantage that the hand feeling of the mirror in the hand-held mode of fig. 12 is not good or the labor-saving effect is not significant when shooting upright. Without limitation, in making the Vlog, it is a common practice to gradually convert a large scene into a local close-up scene by using a push-pull mirror (for example only, common practice also includes moving the mirror laterally, moving the mirror along the track, looking down the mirror, etc.), and at this time, in order to ensure the stability of the handheld stabilizer itself, the user needs to keep holding both hands all the time, which makes both hands of the user not free, which may reduce the evaluation and acceptance of the handheld stabilizer by the user to some extent. Further, during the motion shooting, along with the high-speed motion of the shooting object, in order to prevent the lens from being lost, the handheld stabilizer is often required to be moved quickly to capture the picture, and for the handle shaped like the Chinese character '7', the problem that the wrist burden is large, the user experience is poor and the lens picture is not smooth when the user moves quickly in the handheld mode is also reflected by the user.

Further, with the further enrichment of the functions of the handheld stabilizer, there is an increasing need for a user to be able to visually check the photographing effect. If the requirement of the user is met by externally connecting the external display screen to the handheld stabilizer, the defects that the weights on two sides of the handheld stabilizer are unevenly distributed and the user cannot always and efficiently perform visual inspection due to shielding in certain operation postures are caused, and the user cannot keep attention focused on the external display screen while manipulating the control part of the handheld stabilizer, so that the user is forced to alternately focus on the control of the handheld stabilizer and the inspection of the shooting effect, and the user is not bothered and has poor use experience.

In view of this, those skilled in the art are directed to a handheld electronic stabilizer that overcomes the deficiencies of the prior art.

SUMMERY OF THE UTILITY MODEL

It is therefore an object of the present invention to provide a multifunctional handheld electronic stabilizer, whereby the above-mentioned disadvantages of the prior art are overcome.

In order to accomplish the above task, the present invention provides a multifunctional handheld electronic stabilizer configured to assist a photographing device in photographing at least in a handheld use posture or a holding use posture, comprising: an electronic stabilization device configured to mount a photographing device and to electronically stabilize the photographing device in response to an attitude of the photographing device; a frame connected to the electronic stability augmentation device, comprising: the holding part is closely connected to the electronic stability augmentation device and can be used for realizing a holding use posture, wherein the holding part comprises a cavity which is positioned at the top and can contain at least one part of the electronic stability augmentation device and a connecting part which is positioned at the bottom; a fuselage section connected to the connecting section of the grip section and usable for achieving a hand-held position of use, wherein the fuselage section has a cavity defined therein in which an electrical device can be accommodated, wherein the fuselage section is oriented such that the grip section is substantially identical; wherein the cross-sectional area of the grip portion is designed to be gradually enlarged from the connecting portion toward the top portion so that the outer surface of the grip portion can serve as a positioning curved surface conforming to a hand shape.

Therefore, the multifunctional handheld electronic stabilizer is different from the prior art, has multiple using postures, and enriches the using scenes of the electronic stabilizer so as to meet multiple requirements of professional users. Furthermore, the utility model forms a positioning curved surface which is matched with the hand shape on the outer surface of the holding part. This increases the area of the user's hand that fits the grip portion when gripping, effectively reducing the required gripping force of the hand while achieving the same amount of friction to prevent displacement of the grip portion relative to the user's hand, which allows the user to grip with less effort. On the other hand, because the positioning curved surface is gradually enlarged (big end up), the positioning curved surface is allowed to protect the hand of the user from moving towards the connecting arm of the cradle head which can rotate above the top, the risk that the user is hit by the connecting arm of the cradle head because the user crosses the holding part due to overweight when holding the stabilizer can be effectively avoided, and the safety of the handheld electronic stabilizer in the using process is effectively improved.

In addition, the rack design according to the utility model increases the weight of the rack to improve the inertia of the rack, and enables the gravity center of the pan-tilt to be as close as possible to or even fall into the holding area when the user holds the handheld electronic stabilizer, so that the wrist of the user can stably hold the handheld electronic stabilizer without bearing large torsion, and the fatigue feeling of the user in use is remarkably reduced.

In a preferred embodiment, a base is further included which is connected to the fuselage section, wherein the orientation of the base is designed to be angled relative to the orientation of the fuselage section, preferably in the range of 80 to 90 degrees. Thereby allowing for a reasonable distribution of the specific gravity and placement of the components of the handheld electronic stabilizer.

In a preferred embodiment, wherein the housing of the multi-functional handheld electronic stabilizer is arranged in the following manner: when the handheld electronic stabilizer assists the shooting device to shoot and the frame is in the inclined position, the projection of the integral gravity center of the handheld electronic stabilizer and the shooting device to the horizontal direction falls in the area of the holding part. Therefore, the proportion and the arrangement of all the components of the handheld electronic stabilizer are reasonably distributed, so that the user is allowed to generate no obvious static moment which is obviously perceived by the user under various holding modes. This allows the user to easily operate a heavy or even overweight camera without the user having the undesirable experience of heavy burden and arm fatigue, while still allowing the user to perform a stable mirror-moving in a single hand-held manner. Meanwhile, the handheld electronic stabilizer has a simple structure and a compact integral base body, so that the handheld electronic stabilizer is easy to manufacture at low cost and convenient for a user to carry, store and use.

In a preferred embodiment, the positioning curve is designed with an intrados surface that smoothly transitions to the top surface of the cavity, wherein the curvature of the intrados surface is greater than the curvature of the rest of the positioning curve. Therefore, the distance between the holding area of the user and the gravity center of the holder device is reduced, and the user can hold the holder device more easily. Furthermore, the bending degree of other sections of the positioning curved surface is small, so that the manufacturing difficulty and cost of the holding part are reduced, the overall curve of the holding part is smoother, and the improvement of the quality feeling of products is facilitated.

In a preferred embodiment, the positioning curved surface of the holding portion is added with a friction structure or is textured to increase the surface friction coefficient. Thus, the handheld electronic stabilizer of the present invention is prevented from slipping off the palm of the user's hand.

In a preferred embodiment, a control unit for sending a control signal to the electronic stability augmentation device according to the posture of the shooting device and at least one interactive piece for receiving external input operation are arranged in the base. Thus, by providing the components expected to be heavier in weight in the handheld electronic stabilizer within the base, an optimized configuration of the specific gravity and arrangement of the components of the handheld electronic stabilizer is better achieved to allow a user to perform a stable mirror movement in a single hand-held manner. Meanwhile, the interaction piece is arranged, so that the user can operate the device conveniently by one hand.

In a preferred embodiment, the external surface of the base is detachably connected with an external display unit with adjustable posture, wherein the external display unit can be adjusted to face the user during shooting of the handheld electronic stabilizer auxiliary shooting device. Thus, the exo unit allows the user to operate the interactive element with an idle finger while maintaining the visual sense, so that the user can check the photographing effect with full attention during photographing.

In a preferred embodiment, the apparatus further comprises a lifting bar connected to the base, wherein an angle of the lifting bar relative to the base is adjustable. Thus, by optimizing the arrangement of the lifting bar and the overall weight distribution and arrangement of the handheld electronic stabilizer, a user is allowed to easily operate in a handheld mode without the user significantly experiencing the twisting force or jitter. Further, the user is allowed to manipulate the handheld electronic stabilizer in a more labor-saving and more accurate manner.

In a preferred embodiment, wherein the grip portion is formed in one piece with the fuselage portion. This allows the housing of the hand-held electronic stabilizer to be manufactured in a simpler and less costly manner.

In a preferred embodiment, the electronic stabilizer is a two-axis or three-axis pan-tilt, wherein the heading axis motor of the two-axis or three-axis pan-tilt is connected to the grip of the frame, wherein the angle formed by the two axes of rotation in the two-axis or three-axis pan-tilt is preferably a non-right angle between 60 ° and 70 °.

Reference will now be made in detail to exemplary aspects of a handheld electronic stabilizer in accordance with the present invention with reference to the accompanying drawings. The drawings are provided to present embodiments of the utility model, but the drawings are not necessarily to scale of the particular embodiments, and certain features may be exaggerated, removed, or partially sectioned to better illustrate and explain the present disclosure. The position of some components in the drawings can be adjusted according to actual requirements on the premise of not influencing the technical effect. The appearances of the phrase "in the drawings" or similar language in the specification are not necessarily referring to all of the drawings or the examples.

Certain directional terms used hereinafter to describe the drawings, such as "inner", "outer", "upper", "lower", "top", "bottom", and other directional terms, will be understood to have their normal meaning and refer to those directions as they relate to when viewing the drawings. Unless otherwise indicated, the directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art.

The terms "first," "second," and the like, as used herein, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

Some embodiments of the utility model are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring initially to fig. 1, a multi-functional hand-held electronic stabilizer 10 is shown as a preferred embodiment of the present invention, wherein the multi-functional hand-held electronic stabilizer 10 is capable of allowing a user to easily operate a heavy or even overweight camera without the user having a bad experience of heavy burden and arm fatigue. As an improvement, the multifunctional handheld electronic stabilizer 10 has a plurality of using postures including a handheld using posture and a holding using posture, which enriches the using scenes of the electronic stabilizer to meet various requirements of professional users. As described in detail below, different usage gestures are applicable to different application scenarios. Of course, it can be understood that the multifunctional handheld electronic stabilizer can be expanded to be used in other modes such as shouldering and the like. While still allowing the user to perform a stable mirror exercise in a single hand-held manner. Further, the handheld electronic stabilizer according to the present invention has a simple structure and a compact integral body, and thus is easy to manufacture at low cost and convenient for a user to carry, store and use.

As an example, the multifunctional handheld electronic stabilizer 10 according to the present invention is adapted to assist a camera 20, preferably a cinematograph, which here may be for example a cinematograph camera weighing more than 2 kg and available commercially under the trade name red dragon, to take a photograph. An important consideration for selecting a handheld electronic stabilizer 10 as an auxiliary photographic equipment for users of such heavy-weight cameras is to have good operability and comfort while achieving good stabilization, particularly to allow the user to conform to the user's usage habits and to minimize the user's operational difficulties during the mirror-moving.

To this end, the handheld electronic stabilizer 10 shown here by way of example comprises an electronic stability augmentation device 30 shown in fig. 1 to 2 and a chassis 40 connected to the electronic stability augmentation device 30, where the electronic stability augmentation device 30 can carry a camera device 20 by means of a load board and electronically stabilize the camera device in response to the position of the camera device 20. Specifically, the electronic stability augmentation device 30 herein includes a three-axis pan/tilt head capable of stabilizing the photographing device 20 in three directions of pitch, roll, and heading, wherein the three-axis pan/tilt head includes a pitch motor 31 capable of rotating along a pitch axis, a roll motor 32 capable of rotating along a roll axis, and a heading motor 31 capable of rotating along a heading axis, respectively. Specifically, the attitude information of the camera 20 may be acquired by means of an attitude acquisition unit (such as, but not limited to, an IMU or a gyroscope) provided on a load board or fixedly connected to the camera 20, and then the attitude information may be solved by means of a control unit to obtain an attitude change of the camera 20 in the space, and control signals respectively transmitted to the tilt motor 31, the roll motor 32, and the heading motor 33 may be derived from the attitude change and be correspondingly operated to maintain the camera 20 at a certain position in the space. Here, the rotation axis of the heading motor 33 and the rotation axis of the roll motor 32 form a non-right angle of 60 ° to 70 °. Since the operation of the three-axis pan/tilt head is not the gist of the present invention and the control manner thereof is well known to those skilled in the art, it will not be described herein.

Although the electronic stability enhancement device according to the utility model is described herein in terms of a three-axis head, it will be appreciated by those skilled in the art that the use of a two-axis head is also feasible.

The housing 40 of the handheld electronic stabilizer 10 will first be described below in non-limiting manner with reference to fig. 1-3.

As shown in fig. 1, the frame 40 of the handheld electronic stabilizer 10 includes a grip portion 41 that is connected proximate to the electronic stability augmentation device. The specific structure of the grip portion 41 is better illustrated in the exploded view of fig. 3. Wherein the holding part 41 comprises a circular cavity 411 which is positioned at the top 413 and can contain at least one part of the heading motor 33 of the electronic stability augmentation device 30, in particular the depth of this cavity 411 is designed here to be approximately equal to the height of the stator part of the heading motor 33, so that the heading motor 33 can be integrally accommodated within the grip portion 41 of the frame 40, but only the rotor portion of heading motor 33 is exposed in a manner substantially flush with the top surface of cavity 411, so as to allow only the rotor part of the heading motor 33 for driving the connecting arm to rotate to protrude outside the holding part 41, the vertical distance between the holding part 41 and the heading motor 33 of the electronic stability enhancement device 30 and the center of gravity of the shooting device 20 carried by the heading motor 33 is effectively shortened by means of such an overlapping design, thereby achieving the purpose of reducing the burden of a user in use, and the detailed description will be developed below. It should be noted that although the stator portion of the heading motor 33 is described herein as being fixedly received within the grip portion 41 of the housing 40 and the rotor portion of the heading motor 33 is connected to the rotatable connecting arm (i.e., the motor is positively mounted), those skilled in the art will appreciate that it is possible to receive the heading motor 33 in a retro-fit manner within the grip portion 41 of the housing 40, and that retro-fitting the heading motor will enable further compactness of the hand-held electronic stabilizer since the rotor portion of the heading motor 33 can be designed to be more compact than the stator portion.

Further, the grip portion also includes a connecting portion 414 at the bottom, wherein the connecting portion 414 is designed to connect with the fuselage portion 42 of the airframe 40 as described below, whereby the connecting portion 414 at the top 413 and bottom defines a grip area that allows a user to grip the hand-held stabilizer. In the present embodiment, the cross-sectional area of the grip portion 41 is designed to be gradually enlarged from the connecting portion 414 toward the top 413 (in the bottom-up direction in fig. 1 and 3) so that the outer surface of the grip portion 41 can serve as a positioning curved surface to be fitted to a hand shape. In this context, the cross-sectional area refers to the area enclosed by the outer contour of the grip portion 41, wherein the cross-section is the cross-section of the grip portion 41 along a plane perpendicular to the direction of the grip portion 41 from the connection portion towards the top 413.

As will be understood by those skilled in the art, since the cross-sectional area of the holding portion 41 is gradually enlarged in the bottom-up direction, which is significantly different from the prior art straight-shank type handle in which the cross-sectional area in the direction from the bottom toward the top is designed to be substantially uniform, the design may cause a user to easily feel fatigue when holding the handle of the stabilizer, because the lengths of five fingers of the user are different, for example, the loop defined by the middle finger located at the upper position and the loop defined by the small finger located at the lower position are not uniform, and if the handle of the stabilizer is designed to be uniform in the cross-sectional area in the upper-lower direction, the middle finger may encircle the handle while the small finger may not completely encircle the handle at the same time, thereby causing the user to easily feel fatigue when holding the handle. Therefore, in order to conform to the shape of the human body when holding the hand, the grip of the present invention adopts a gradually expanding design of the sectional area along the direction from bottom to top, which makes the user have better comfort and more reliable when holding the grip 41.

In the present embodiment, the cross-sectional area of the grip portion 41 is designed to be gradually enlarged in a direction from the connecting portion 414 of the free portion 31 toward the top connecting portion 413 (i.e., in a direction from the bottom to the top). In other words, the cross-sectional area of the grip portion 41 in the direction from the bottom to the top is gradually increased, thereby allowing the outer surface of the grip portion 41 to serve as a positioning curved surface conforming to the shape of a hand. The specific increase in the cross-sectional area of the grip portion 41 is set according to actual needs, and this embodiment is not particularly limited thereto.

Due to the grip portion 41 having the divergent design, a positioning curved surface conforming to a hand shape can be formed on the outer surface of the grip portion 41. This increases the area of the user's hand that fits the grip portion 41 when gripping, and effectively reduces the required gripping force of the hand while obtaining the same amount of friction to prevent displacement of the grip portion 41 relative to the user's hand, which allows the user to grip with less effort. Further, since the positioning curved surface is gradually enlarged (large at the top and small at the bottom), the positioning curved surface can protect the hand of the user from moving towards the connecting arm of the cradle head which can rotate above the top, so that the risk that the user crosses the holding part 41 due to the overweight when holding the stabilizer 10 and is hit by the connecting arm of the cradle head can be effectively avoided, and the safety of the handheld electronic stabilizer 10 in the using process is effectively improved.

In addition, the heading motor is arranged in the holding part 41, so that the self weight of the rack is increased, the inertia of the rack 40 is improved, the vibration of the rack 40 during the motion shooting is smaller, the relative displacement between the holding part 41 and the hand is further prevented, and on the other hand, the gravity center of the tripod head can be as close as possible to or even fall into a holding area when the user holds the handheld electronic stabilizer 10, so that the wrist of the user can stably hold the handheld electronic stabilizer 10 without bearing larger torsion, and the fatigue of the user during use is remarkably reduced.

Further preferably, as shown in fig. 3, the positioning curved surface of the holding portion 41 is designed to have an inner curved surface smoothly transitioning to the top surface of the cavity 411, so that no seam is generated between the holding portion 41 and the three-axis pan/tilt head carried thereby due to size change, thereby causing a risk of scratching the hand of the user and a problem of poor evaluation of product quality and appearance. It is further preferred that the curvature of the intrados (arranged adjacent to the top) is greater than the curvature of the rest of the positioning curved surface, i.e. the entire positioning curved surface is curved to a greater extent in the section adjacent to the top, which makes this section less dominant in the overall height of the grip 41, thus further reducing the distance between the user gripping area and the center of gravity of the head device, making it more labour-saving for the user to grip. And the bending degree of other sections of the positioning curved surface is small, so that the manufacturing difficulty and the cost of the holding part 41 are reduced, and the overall curve of the holding part 41 is smoother. The specific difference of the bending curvatures is set according to actual needs, and this embodiment does not specifically limit this.

It is further preferred here that the grip portion 41 is designed, for example, to be approximately oval in cross-section, which conforms to the palm of the user's hand, in order to facilitate gripping with one hand of the user. In order to increase the friction between the palm of the user and the grip portion 41, an anti-slip texture or a friction pad may be provided on the outer circumferential surface of the grip portion 41. Meanwhile, at least one interactive element 412 for receiving an input operation of a user is preferably arranged adjacent to the grip portion 41, where the interactive element 412 arranged at the right side of the grip portion 41 in fig. 1 is, for example, a stick, so as to allow the user to operate the electronic stabilizer 10 with a free finger while holding the handheld electronic stabilizer 10 with a single hand, which is helpful for improving the user experience.

In fig. 1, a fuselage portion 42 integrally connected to a connecting portion 414 of a grip portion 41 is provided below the grip portion 41, wherein the fuselage portion 42 is designed to have substantially the same orientation as the grip portion 41. For example, when the handheld electronic stabilizer 10 shown in fig. 1 is in the upright posture, the body portion 42 is located directly below the grip portion 41. As a possible way, the holding portion 41 and the fuselage portion 42 may be made in one piece by injection molding, wherein the fuselage portion 42 is also designed to be hollow, so as to define a cavity 421 (see fig. 3) in the fuselage portion 42, which can accommodate an electrical device, including but not limited to a power supply 422, such as a battery, and also a control portion of the electronic stability augmentation device 30, such as powered by the power supply 422. It will of course be appreciated by those skilled in the art that the gripping portion 41 and the fuselage portion 42 may also be made separately and then assembled together by means of a snap-fit or screw connection.

Further, in fig. 1, a pedestal 43 connected to the fuselage portion 42 is included, wherein the pedestal 43 is designed, for example, substantially in the shape of a truncated cone and is oriented at an angle in the range of, for example, 80 degrees to 90 degrees with respect to the orientation of the fuselage portion 42. In fig. 1, for example, the angle is 90 degrees. On the upper surface or top surface of the base 43, an external display unit 432 such as an OLED screen is detachably connected in a nested manner, wherein the external display unit 432 can be pivoted in a nested portion of the base 43 to allow a user to adjust its own posture (corresponding to the angle of the base 43), which allows the external display unit to be adjusted to face the user during photographing by the handheld electronic stabilizer-assisted photographing device (see, for example, fig. 4). At least one interactive member 431 for receiving an external input operation, for example, from a user is provided on the base 43 adjacent to the external unit 432, and the interactive member 431 may be, for example, a knob, a button, a wheel, or the like. Also, a control unit or the like may be included in the base 43, for example, to input a control signal of a user via the interactive member 431 to derive a control signal for the electronic stability increasing apparatus 30 to read. In order to facilitate interaction with the outside, a plurality of electrical interfaces including an audio interface and a charging port may be further provided on the base 43.

As will be better understood in conjunction with the following description, the design of the base 43 according to the present invention will provide at least the following benefits: the proportion of each component of the handheld electronic stabilizer can be reasonably distributed, so that a user can not generate obvious static moment which is obviously sensed by the user in various holding modes; the exo unit allows the user to operate the interactive member 431 with a free finger while maintaining the visual sense, so that the user can check the photographing effect with full attention during photographing.

Optionally, to allow the handheld stabilizer to be used in a variety of mirror movements, a lifting bar 44 is also included that is removably attached to the base 43, wherein the lifting bar 44 is attached to the base 43, such as in a pivoting manner, such that the angle of the lifting bar relative to the base 43 is adjustable, which allows a user to operate the handheld stabilizer in a handheld mode. Also optionally, the base 43 is further provided with at least one interface 433 on the underside for engagement, for example, by a tripod or the like, which allows a user to rest the handheld electronic stabilizer 10 on a table or other work surface with the aid of a tripod when it is temporarily deactivated. Further, the interface 433 can also be designed to connect a required accessory (such as a plug-in battery) to the base 43 of the handheld electronic stabilizer through the interface 433, which not only prolongs the service life of the handheld electronic stabilizer, but also further functions as a weight increasing function, which allows a user to save more labor when holding the stabilizer with one hand. Preferably, the base 43 is further provided with a V-shaped slot at the bottom, which can be used for clamping with a foot stand or a backup battery with a V-shaped buckle.

The components of the handheld electronic stabilizer 10 according to the present invention are better illustrated in the exploded view of fig. 3, and will not be described in detail herein since they have been described in detail above.

The use of the handheld electronic stabilizer 10 according to the present invention will be further described with reference to fig. 4 to 6, whereby the difference in performance of the handheld electronic stabilizer 10 of the present invention from the existing handheld electronic stabilizer can be self-evidently demonstrated.

Fig. 4 shows a use configuration of the handheld electronic stabilizer 10 according to the utility model, which may be a follower mirror, for example. The follow-up mirror refers to a lens moving along with a subject (e.g., a person) and a user can follow up shooting from the front and back directions of the person, but the user needs to keep the same moving speed as the subject and pay attention to safety under the feet. When the lens is moved with following, it is often necessary to tilt the hand-held electronic stabilizer 10 forward at an angle of 30 to 44 degrees from the vertical direction, for example, in accordance with the height of the photographic subject to obtain a satisfactory angle of view of the lens.

Here, when the handheld electronic stabilizer 10 shown in fig. 4 assists the photographing apparatus 20 in photographing and the stand 40 is in the forward tilted position, the photographing apparatus 20 and the electronic stabilizing device 30, the body section 42 and the built-in electric devices, and the base 43 and the external unit 432 thereof are expected to be the heaviest components at this time. Wherein the photographing device 20 and the electronic stabilizing device 30 have a center of gravity in front of the grip portion 41 (see the first gravity line G1 in fig. 4), and thereby generate a counterclockwise moment (as shown in fig. 4) around the grip portion 41. The fuselage portion 42 and the built-in electric devices as well as the base 43 and its external unit 432 have a center of gravity behind the grip portion 41 (see the second center of gravity G2 in fig. 4). They thereby exert a clockwise moment about the grip portion 41. This overlapping design effectively shortens the vertical distance between the grip portion 41 and the heading motor 33 of the electronic stabilizer 30 and even the center of gravity of the camera 20 carried by the grip portion 41 due to the overlapping of the heading motor 33 of the electronic stabilizer 30 within the grip portion 41, so that although the camera 20 and the electronic stabilizer 30 would be very heavy components, it is still possible for the counter-clockwise moment they generate around the grip portion 41 to be balanced by the moment generated by other components of the handheld electronic stabilizer 10 (such as, but not limited to, the body portion 42 and the built-in electrical devices as well as the base 43 and its external unit 432, etc.). That is, the general weight distribution of the handheld electronic stabilizer 10 is in a dumbbell-shaped distribution of "heavy ends, middle grab".

Thus, it is possible to position the hand-held electronic stabilizer 10 such that, when following the mirror movement, the projection of the overall center of gravity of all the components of the hand-held electronic stabilizer 10 to the horizontal direction (i.e., the left-right direction in fig. 4) falls within the grip region (defined by the connecting portion 414 of the top 413 and bottom of the grip 41) of the grip 41, so that the total static moment around the grip 41 approaches or is substantially zero. The overall center of gravity of handheld electronic stabilizer 10 is thus located in the area of grip portion 41, so that when a user holds handheld electronic stabilizer 10 with a hand, handheld electronic stabilizer 10 balances about a point in the area of grip portion 41, and at this time, the user only needs to try to find the balance point several times to easily keep the balance of handheld electronic stabilizer 10 in a single-hand manner, which greatly reduces the burden on the user in the case of an overweight load, and at this time, control of the stabilizer can also be achieved by the user operating, for example, interactive element 412 near grip portion 41 with the remaining fingers on grip portion 41. Since the hand-held electronic stabilizer 10 is substantially gravity-balanced, it does not easily topple or shake back and forth during the auxiliary photographing, which advantageously ensures the photographing effect of the photographing device 20.

Further, as shown in fig. 4, due to the orientation of the base 43, the external display unit 432 is facing the user's view angle during the shooting of the inclined auxiliary shooting device, the user can focus on the external display unit 432 in a direct visual manner during the sports shooting, and since the user observes the external display unit 432 in a top view angle, the user is allowed to scan the road surface ahead while observing the external display unit 432 intensively even if the user performs the sports shooting outdoors, which well ensures the safety of the user's feet during the shooting. Since the external display unit 432 is provided, it is not necessary to additionally install a monitor, a monitor bracket and other devices on the handheld electronic stabilizer 10, which reduces the overall weight of the handheld electronic stabilizer 10, and reduces the purchasing cost of the user and the number of parts to be carried when the user goes out for shooting.

From the above, it can be seen that a user will get a good user experience during the follow-up mirror with the handheld electronic stabilizer 10 of the present invention: such as ease of holding with one hand, substantially no forward or backward shake of the lens, ensuring that attention is always focused on the picture effect of shooting, and improving safety under the feet during shooting by the user, which are significantly different from the conventional handheld electronic stabilizers in performance.

Fig. 5 to 6 further show another use configuration of the handheld electronic stabilizer 10 according to the utility model, which may be, for example, a low-angle mirror. The low-angle mirror moving means that the lens shoots the shooting subject under the condition of low angle. To save more effort when shooting at low angles, a lifting bar 44 is added to fig. 5 and 6 to allow the user to operate the handheld electronic stabilizer 10 in a "hand-held" mode in a position that is not overly prone. When taking such a "handheld" use posture for shooting, any part of the pan/tilt head 30 is far away from the body (particularly the legs) of the user to avoid injury caused by unintended contact, and therefore, the handheld use posture is applicable to shooting with the pan/tilt head 30 following the steps of the user, close-to-ground movement in a narrow space, and the like.

In the prior art, when the electronic stabilizer is carried by hand in a 'hand-carrying' mode, the lifting rod is arranged at the upper position of the machine body. When shooting at a low angle, if the dead weight of the shooting device is large, and if the course motor rotates to stabilize the shooting device, the reaction force in the course motor can be directly transmitted to the lifting rod at the upper position of the body part, so that the user can be given a very obvious shaking sense, the user can be prompted to use the other hand to inhibit the shaking, and the hands of the user can not be liberated.

As shown in fig. 5-6, unlike the prior art, the lifting bar 44 of the hand-held electronic stabilizer 10 according to the present invention moves down from the upper position of the body portion to the side of the base 43 located at the far side of the body portion 42, which on the one hand moves the lifting bar significantly away from the heading motor 33 as a source of the torsional force, so that the user does not significantly experience this torsional force or vibration, and, on the other hand, due to the housing arrangement of the handheld electronic stabilizer 10 according to the present invention, i.e. along both the fuselage section 42 and the base 43, have a certain weight which on the one hand is balanced itself around both sides of the grip, and on the other hand has an inertia which is sufficient to damp the torsional forces or vibrations from the heading motor 33 well, the user does not feel a noticeable shaking sensation when using the handheld electronic stabilizer 10 with the lifting bar 44, so that the user can carry the electronic stabilizer 10 by hand with one hand to carry the mirror at a low angle.

As shown in more detail in fig. 6, the lifting lever 44 is designed here as a telescopic lever with a certain inclination, wherein it can be flexibly adjusted depending on the weight of the camera 20. The tilt angle of the lift lever 44 is designed such that the user's grip position on the lift lever 44 is substantially in the region directly above the grip portion 41 to avoid generating unnecessary tilting moment.

Further, as can be seen from fig. 6-8, when the rack is tilted in the portable mode, the overall center of gravity of the handheld electronic stabilizer 10 according to the present invention generally falls within the area of the holding portion 41, and then if the lifting bar is disposed at the upper position of the machine body (i.e. within the area of the holding portion 41 or in the area adjacent to the holding portion 41) in the prior art, the user needs to move the wrist to apply a torque force to the handheld electronic stabilizer by means of the lifting bar when the user needs to move the handheld stabilizer to capture a picture quickly. Since the handheld electronic stabilizer 10 is generally rotated with the overall center of gravity as a pivot point, the connecting portion of the lifting bar and the handheld electronic stabilizer 10 is located too close to the overall center of gravity, which causes a large torsion force to be applied to the user's wrist for moving heavy loads, which may cause a large burden on the user's wrist. Further, the point of application of force is too close to the overall center of gravity as a pivot point, so that the lens is moved by a certain angle even if the wrist of the user is slightly shaken, which increases the difficulty of the user in accurately adjusting the lens movement angle. As a result, users with less experience often find that the shot is not smooth enough when moving the shot, which disadvantageously increases the cost and difficulty of post-editing.

In contrast, as shown in fig. 6, since the lever 44 is moved down from the upper position of the body portion to the side of the pedestal 43 located on the far side of the body portion 42, the distance between the lever 44 and the overall center of gravity of the handheld electronic stabilizer 10 is significantly increased, and the distance D1 between the connecting portion of the lever 44 and the overall center of gravity is shown here as an example. In other words, as the user's wrist rotates to apply a rotational force to handheld electronic stabilizer 10, the moment arm of the overall center of gravity of the rotational moment as a pivot point increases significantly, which allows the user to rotate handheld electronic stabilizer 10 at an angle in the counterclockwise direction or the clockwise direction without applying an excessive torque force, thereby alleviating the problem of an excessive burden on the user in the handheld mode. Further, due to the scissors effect of the long arm, the user needs to rotate the lifting rod 44 a wider distance to rotate the handheld electronic stabilizer 10 to the desired angle, which is advantageous for filtering the effect of the hand shake of the user (especially the inexperienced user) on the angle of the lens, so that even the inexperienced user can smoothly rotate the lens to ensure the quality of the shot picture.

In particular, in fig. 7 and 8, respectively, a top view is shown, on the basis of fig. 6, turned in a counterclockwise direction or in a clockwise direction by a certain angle in the portable mode. As shown in fig. 7, when the forward-located photographic subject moves to the left side of fig. 7, the photographing device 20 needs to move to the left side quickly for the pursuit photographing, which means that a counterclockwise torque needs to be applied to the handheld electronic stabilizer 10 to pivot it about its entire center of gravity by an angle a (the angle a is an angle between the longitudinal axis L in the neutral position of fig. 6 and the longitudinal axis L1 in the left turn position of fig. 7). Since the distance D1 between the connecting portion of the lifting bar 44 and the overall center of gravity is significantly increased in the present invention, the user only needs to apply a small force by means of the lifting bar 44 to drive the camera device 20 and the handheld electronic stabilizer 10 to rotate counterclockwise by the angle a. Further, since there is a distance D1 between the connection portion of the lifting lever 44 and the center of gravity of the whole, the photographing device 20 and the handheld electronic stabilizer 10 are driven to rotate counterclockwise to the angle a only when the lifting lever 44 is moved by a distance D1 × sin (a) in the left-right direction of fig. 7. This means that even if a user with a poor experience accidentally shakes a certain amount in the left-right direction of fig. 7, the image pickup device 20 is not noticeably shaken in a noticeable manner, which effectively reduces the demand for the user experience. Even a user who newly uses the handheld electronic stabilizer 10 according to the present invention can achieve satisfactory results with little training, and the difficulty of the hands is significantly reduced. Further, since the distance in the left-right direction is significantly increased, this allows the user to act at a nearly constant speed, thereby making the rotation of the photographing device 20 smoother, which ensures that high-quality image quality can be always photographed during the motion photographing, reducing the cost and expense of the post-processing.

As shown in fig. 8, when the forward-located photographic subject moves to the right side of fig. 8, the photographic device 20 will also be moved to the right rapidly, which means that a clockwise torque is applied to the handheld electronic stabilizer 10 to pivot it about its entire center of gravity by an angle a' (which is the angle between the longitudinal axis L in the neutral position of fig. 6 and the longitudinal axis L2 in the right-turn position of fig. 8). Since the distance D1 between the connecting portion of the lifting bar 44 and the overall center of gravity is significantly increased in the present invention, the user only needs to apply a small force by means of the lifting bar 44 to rotate the camera 20 and the handheld electronic stabilizer 10 clockwise by the angle a'. Further, since there is a distance D1 between the connection portion of the lifting lever 44 and the center of gravity of the whole, when the lifting lever 44 is moved by a distance D1 si, (a) in the left-right direction of fig. 8, the camera 20 and the handheld electronic stabilizer 10 are driven to rotate clockwise to the angle a. This means that the advantageous technical effects that can be achieved in fig. 7 can also be achieved when the hand-held electronic stabilizer 10 is rotated clockwise, which will not be described in detail here.

It is emphasized that although the use of the handheld electronic stabilizer 10 according to the present invention is exemplarily described in fig. 4-6 with the following mirror and the low-angle mirror, respectively, it is to be noted that the use of the handheld electronic stabilizer 10 of the present invention for other mirror movements, such as, but not limited to, the horizontal mirror movement and the top mirror movement, etc., is also feasible.

Further, as another preferred mode of the present invention, an adapter 5 adaptable to the handheld electronic stabilizer of the present invention is shown in fig. 9-10 as an alternative to the base 43, wherein the adapter 5 is configured to adjustably connect the bail 44 to the frame 40 of the handheld electronic stabilizer 10. Specifically, the adapter 5 includes a main body configured to substantially conform to the cross-sectional shape of the fuselage portion 42 of the frame 40, gear discs 51 on either side of the main body, and shoes (optional) below the main body. Wherein the weight of the body is designed to be comparable to the weight of the base 43 to effect a rational distribution of the specific gravity and arrangement of the components of the handheld electronic stabilizer.

Further, the toothed disc 51 on both sides of the main body may be designed as a circular tooth surface, wherein the tooth surface is formed with a plurality of first teeth arranged at intervals, and a first tooth slot is formed between two adjacent first teeth, and each first tooth slot may be a clamping position. Correspondingly, an engaging surface capable of engaging with the coupling surface is provided at the end of the lifting rod 44, wherein the engaging surface is also formed with a plurality of second teeth arranged at intervals, and each second tooth may be an engaging portion. When the lifting lever 44 is attached to the toothed plates 51 on both sides of the main body, the second teeth on the lifting lever 44 can be received in the first teeth grooves as one engaging position, and the lifting lever 44 is engaged with the toothed plates 51 on both sides of the main body, so that the lifting lever 44 can be reliably held at a desired position. When the same second tooth is received in a different first tooth slot, the lifting bar 44 can be held in a different position relative to the same adapter 5; in other words, each of the engaging portions as the second teeth can be engaged with one engaging position, and when the same engaging portion is engaged with a different engaging position, the lever 44 can be rotated relative to the adapter and can be held by the adapter 5. Further, since the plurality of first teeth are equally spaced around the entire circumference of the toothed plate 51, each second tooth can be received in the first tooth groove at any position on the circumference, so that the lifting bar 44 can rotate in a range of 0 ° to 360 ° with respect to the adapter 5 and can be held on the adapter 5. Further, since the toothed plates 51 are symmetrically provided at both sides of the body, it is convenient for a user to arbitrarily switch the attachment manner of the lifting bar 44 as desired.

Preferably, shoes 53a and 53b are provided under the body of the adapter 5 to allow the adapter 5 to further expand in functionality. As a practical matter herein, there is also provided a brace 6 that allows a user to easily hold the hand-held stabilizer 10 during use of the hand-held stabilizer 10. Referring specifically to fig. 11 a-11 b, the bracketing 6 includes a body generally designed in a T-shape, a support surface 62 at one end of the body, and a plurality of runners 61 extending from the support surface 62 toward the opposite end. In use, a user may insert and grip the shoes 53a and 53b provided under the body of the adaptor 5 into the slideway 61 of the brace 6, thereby fixedly attaching the brace 6 to the chassis of the hand-held stabiliser 10. If the user now holds the grip portion 41, which is connected to the electronic stabilizing device 30, for example, in a vertical manner, the user can rest his elbow on the support surface 62 with ease, resulting in a good use experience for the user. Due to the arrangement of the plurality of sliding ways, the distance between the supporting surface 62 and the frame 40 of the handheld stabilizer 10 can be adjusted to adapt to the elbow positions of different users, which on one hand helps to enrich the functions of the adapter and on the other hand helps to improve the user experience.
