detailed description

The foldable stabilizer will be further described below in conjunction with the drawings and specific embodiments.

As shown in Fig. 2, Fig. 14 and Fig. 15, the foldable stabilizer 10 of an embodiment includes a first arm 11, a second arm 12, a clamping member 13, a first driving member 14, and a second driving member 15 , rechargeable battery 16 and control system 17.

As shown in FIG. 2 and FIG. 3 , the first arm 11 has a connecting end 11 a and a free end 11 b. In this embodiment, three usage modes of the stabilizer 10 are enumerated, which are vertical type (Fig. 3), horizontal type (Fig. 4) and vertical type (Fig. 5). When the stabilizer 10 is in the vertical holding type and the horizontal holding type, the free end 11b is the hand-holding end.

One end of the second arm 12 is rotatably connected to the connecting end 11a. It should be noted that the rotatable connection between the second support arm 12 and the connection end 11a means that, without opening the stabilizer 10, when the second support arm 12 is moved (for example, manually) by external force, the second support arm 12 The arm 12 is rotatable relative to the first arm 11 . Specifically, in this embodiment, the axis of rotation of the second arm 12 relative to the first arm 11 is perpendicular to the first arm 11, and the second arm 12 can rotate within a range of 360° relative to the first arm 11. Internal rotation.

The clamping member 13 is used to clamp the photographing equipment. In this embodiment, the clamping member 13 is used to clamp mobile phones, tablets and other devices with a shooting function. It can be understood that the clamping member 13 can also be used to clamp professional shooting equipment such as a camera.

The clip 13 is rotatably connected to an end of the second arm 12 away from the first arm 11 . It should be noted that the rotatable connection between the clamping part 13 and the second support arm 12 means that, without opening the stabilizer 10, when the clamping part 13 is toggled (for example, manually) by an external force, the clamping part 13 can rotate relative to the second arm 12. Specifically, in this embodiment, the rotation axis of the clamping member 13 relative to the second support arm 12 is perpendicular to the second support arm 12, and the clamping member 13 can rotate within a range of 360° relative to the second support arm 12 . And when the second support arm 12 was perpendicular to the first support arm 11, the rotating shaft (the rotating shaft of the clamping member 13) that the clamping member 13 rotated relative to the second support arm 12 was the same as that of the second support arm 12 relative to the first support arm. 11. The rotating shaft of rotation (the rotating shaft of the second support arm 12) is vertical.

The first driving member 14 is disposed on the first arm 11 and connected to the rotation shaft of the second arm 12 . Therefore, two ways can be used to rotate the second support arm 12, one is to use external force to stir the second support arm 12, the other is to open the stabilizer 10, and drive the first driving member 14 through electric energy, etc., the first The driving member 14 then drives the second support arm 12 to rotate. Specifically, in this embodiment, the first driver 14 is a motor, the second arm 12 is connected to the output shaft of the first driver 14 , and the output shaft of the motor is the rotation shaft of the second arm 12 .

The second driving member 15 is disposed on the second support arm 12 and connected to the rotating shaft of the clamping member 13 . Thereby, two ways can be used to rotate the clamping member 13, one is to use external force to stir the clamping member 13, the other is to open the stabilizer 10, and drive the second driving member 15 by electric energy, etc., the second driving member 15 drives the clamping part 13 to rotate again. Specifically, in this embodiment, the second driving part 15 is a motor, the clamping part 13 is connected to the output shaft of the second driving part 15 , and the output shaft of the motor is the rotating shaft of the clamping part 13 .

In order to carry the stabilizer 10 conveniently, in the embodiment, the stabilizer 10 is designed as a foldable structure. Before using the stabilizer 10 , it is usually necessary to manually unfold the stabilizer 10 first, so that the first arm 11 and the second arm 12 of the stabilizer 10 change from an overlapping state to an angled state. In this embodiment, when the above-mentioned stabilizer 10 is used, before the stabilizer 10 is not opened, it is usually necessary to manually unfold the stabilizer 10 first, that is, from the folded state shown in FIG. 2 (the first arm 11 and the second The support arms 12 are in the overlapped state) is transformed into the angle state between the first support arm 11 and the second support arm 12 shown in FIG. 3 .

When the stabilizer that does not hold the shooting equipment is in the unfolded state, the entire stabilizer can be in a balanced state. This balanced state has been determined when the stabilizer is originally designed, and is called the initial balance. In this embodiment, taking the perspective shown in FIG. 3 as an example, the operator holds the free end 11b vertically, the clamping member 13 faces the operator, and is facing the operator. The second support arm 12 and the clamping member 13 The center of gravity of the formed whole is located on the rotating shaft of the second support arm 12 , the center of gravity of the clamping member 13 is located on the rotating shaft of the clamping member 13 , and the entire stabilizer 10 is in a vertical initial balance state.

After clamping the shooting equipment on the clamping piece 13, due to the uneven distribution of the gravity of the shooting equipment itself, the deviation of the clamping position, etc., the overall center of gravity of the clamping piece 13 and the shooting equipment will shift, and it will not be located in the clamping position. On the rotating shaft of the holding part 13, the initial balance is broken, and the holding part 13 will rotate around the rotating shaft of the holding part 13 (taking the perspective shown in Figure 3 as an example, when the center of gravity is leftward, the holding part 13 rotates counterclockwise, When the emphasis is on the right, the clamping member 13 rotates clockwise).

After clamping the shooting equipment on the clamping piece 13, the newly added shooting equipment will break the overall balance formed by the second support arm 12 and the clamping piece 13, that is, the shooting equipment, the second support arm 12 and the clamping piece The center of gravity of the whole formed by 13 is not located on the rotating shaft of the second support arm 12 . Taking the angle of view shown in FIG. 3 as an example, when the photographing device is clamped on the front surface of the clamping member 13, the center of gravity of the whole composed of the photographing device, the second support arm 12 and the clamping member 13 is relative to the second support arm 12. The rotating shaft of the rotating shaft has moved forward, causing the second support arm 12 to rotate 90° around the first support arm 11 toward the side where the operator is located, causing the shooting surface (the surface with the camera) of the shooting device to face downward (towards the ground), The shooting surface of the shooting equipment cannot face the operator directly.

It should be noted that the angle of view shown in FIG. 3 is the angle of view of using the stabilizer 10 to hold the shooting device for self-portrait, so that the shooting device is facing the operator, which is essentially to make the shooting device face the object.

In a traditional stabilizer, after the shooting equipment is installed, the stabilizer is turned on, and the first driving member 14 and the second driving member 15 start to work, and the first driving member 14 performs work on the second support arm 12, so that the second support arm 12 Reverse rotation returns to the initial equilibrium state shown in FIG. 3 , and the second driving member 15 acts on the clamping member 13 to make the clamping member 13 reversely rotate and return to the initial equilibrium state shown in FIG. 3 . That is, when the stabilizer is not turned on, after the photographing equipment is installed, the photographing surface of the photographing equipment cannot face the operator so as to face the operator. After the shooting equipment is installed, the stabilizer needs to be turned on. After the first driving member 14 and the second driving member 15 have done work, the shooting equipment can face the operator and shoot. However, the work done by the first driving element and the second driving element will inevitably lead to higher power consumption of the stabilizer 10 .

In order to solve the problem of high power consumption of the stabilizer 10 , in this embodiment, manual adjustment is performed first, so that the center of gravity of the whole composed of the clamping member 13 and the shooting device is located on the rotation axis of the clamping member 13 . The specific process is as follows:

Taking the angle of view shown in Figure 3 as an example, after clamping the photographing device on the clamping part 13, the photographing device is manually moved so that the center of gravity of the entirety of the clamping part 13 and the photographing device is located on the rotating shaft of the clamping part 13, so as to achieve new balance. During the process of moving the shooting device, keep releasing the hand to check whether it is balanced, until the clamping member 13 no longer rotates relative to the second support arm 12 after the hand is released. When the shape of the shooting device is regular and its own gravity is evenly distributed, the clamping member 13 is clamped in the middle of the shooting device, which is a balanced state.

When the photographing device is a mobile phone, the mobile phone is directly clamped on the splint 13d of the clamping member 13 in the viewing angle shown in FIG. 3 , and the mobile phone is in a vertical state. When it is necessary to make the mobile phone in a lying state, it is necessary to rotate the clamping part 13 first, so that the clamping part 13 is converted from the state shown in Figure 3 to the state shown in Figure 6. During this rotation, the clamping part 13 The center of gravity is always located on the rotating shaft of the clamping member 13, and the state shown in FIG. 3 is converted to the state shown in FIG. 6, and the entire stabilizer 10 is still in a balanced state.

In this embodiment, the second support arm 12 can also move relative to the first support arm 11 so that the center of gravity on the second support arm 12 is located on the rotation axis of the second support arm 12, and the moving track of the second support arm 12 Intersect with the second arm 12 (ie not parallel). It should be noted that, in this embodiment, the moving trajectories are all straight lines. In other embodiments, when the moving track is a non-straight line such as a curve, broken line, or wavy line, the intersection of the moving track of the second arm 12 and the second arm 12 refers to the connection between the starting point and the end point of the moving track. Intersect with the second arm 12.

Taking the angle of view shown in FIG. 3 as an example, when the photographing device is clamped on the front surface of the clamping member 13, the overall center of gravity of the photographing device, the second support arm 12 and the clamping member 13 is relative to the second support arm 12. The axis of rotation will move forward, that is, towards the operator. After clamping the photographing equipment on the front surface of the clamping member 13, and before releasing the hand, the second support arm 12 is moved backward relative to the first support arm 11 away from the operator to achieve a new balance. In the process of moving, constantly release the hand to detect whether it is balanced, until the second support arm 12 no longer rotates relative to the first support arm 11 after the hand is released. The whole center of gravity formed by the parts 13 is located on the rotating shaft of the second support arm 12, and a new balance has been reached.

In this embodiment, the apparent phenomenon of adjusting the overall center of gravity of the shooting device, the second support arm 12 and the clamping member 13 is to make the second support arm 12 (that is, the shooting device) approach or move away from the object to be photographed.

In this embodiment, before the power is turned off (that is, before the stabilizer 10 is not turned on), the center of gravity of the photographing device, the second support arm 12 and the clamping member 13 is located at the second support arm 13 through manual adjustment. on the rotation axis of the arm 12, so that the photographing surface of the photographing device faces the operator (subject). After the stabilizer 10 is turned on, there is no need for the first driving member 14 and the second driving member 15 to perform additional work to make the shooting surface of the shooting device face the operator (object). Therefore, the power consumption of the stabilizer 10 of this embodiment is relatively low.

It can be understood that, in other embodiments, it is also possible to manually move the shooting device alone, so that the center of gravity of the whole of the clamping part 13 and the shooting device is located on the rotating shaft of the clamping part 13, or only manually move the second arm 12, so that the center of gravity of the photographing device, the second support arm 12 and the clamping member 13 is located on the rotation axis of the second support arm 12, and the other center of gravity is adjusted through the driving member.

Further, in this embodiment, when the second arm 12 is perpendicular to the first arm 11 , the second arm 12 is perpendicular to the moving track. In this embodiment, several situations shown in Fig. 3-5 and Fig. 7 are listed.

Taking the angle of view shown in FIG. 3 as an example, FIG. 3 is a structural schematic diagram of the operator holding the free end 11 b of the stabilizer 10 vertically. In the viewing angle shown in FIG. 3 , the moving track and the vertically arranged second arm 12 and the first arm 11 form a three-dimensional Cartesian coordinate system. At this time, the first arm 11 is a pitch arm, and the second arm 12 is a roll arm.

Taking the angle of view shown in FIG. 4 as an example, FIG. 4 is a structural schematic diagram of the operator holding the free end 11 b of the stabilizer 10 horizontally. In the viewing angle shown in FIG. 4 , the moving track is parallel to the extension direction of the first arm 11 . At this time, the first arm 11 is a pitch arm, and the second arm 12 is a roll arm.

Taking the angle of view shown in FIG. 5 as an example, FIG. 5 is a schematic structural diagram when the first arm 11 of the stabilizer 10 is placed on a platform such as a desktop. In the viewing angle shown in FIG. 5 , the moving track and the vertically arranged second arm 12 and the first arm 11 form a three-dimensional Cartesian coordinate system. At this time, the first support arm 11 is a yaw arm, and the second support arm 12 is a roll arm.

Taking the viewing angle shown in FIG. 7 as an example, in other implementation manners, the moving track may also intersect with the extension direction of the first arm 11 (not parallel but perpendicular). Taking the angle of view shown in FIG. 3 as an example, assume that the side of the first arm 11 close to the second arm 12 has a chute a and a chute b (please refer to FIG. 7 ), and the second arm 12 is connected to the first arm 12. A side of the arm 11 close to the second arm 12 is vertical, so the second arm 12 must be perpendicular to the chute a and the chute b. The chute a and the chute b intersect with the extending direction of the first arm 11 respectively. When the moving track coincides with the chute a or the chute b, that is, the moving track intersects with the extending direction of the first arm 11 . At this time, when the second support arm 12 moves along the moving track, the moving component can also make the center of gravity of the second support arm 12 be located on the rotation axis of the second support arm 12 .

When the angle between the first support arm 11 and the second support arm 12 in the viewing angle shown in FIG. 3 is greater than 90° or less than 90°, in order to make the shooting device face the operator, either the operator needs to move the position, Either the operator holding the first arm 11 needs to twist his arm, so that the hand of the operator holding the first arm 11 is in a twisted state, and the user experience is poor. However, in this embodiment, the second support arm 12 is perpendicular to the first support arm 11, and the second support arm 12 is also perpendicular to the moving track, and during the movement of the second support arm 12, the second support arm 12 will always be Being perpendicular to the first support arm 11 , the shooting device can be directly facing the operator without moving the object to be photographed or twisting the arm of the operator holding the first support arm 11 , and the user experience is better.

Further, as shown in FIG. 3 and FIG. 8 , in this embodiment, the aforementioned stabilizer 10 further includes a connecting piece 100 and a first locking piece 200 . One end of the connecting member 100 is rotatably connected to the first driving member 14 , and the other end is provided with a sliding slot 110 . One end of the second support arm 12 can move in the slide slot 110 . The first locking member 200 is used to relatively fix the second support arm 12 and the connecting member 100 . Specifically, in this embodiment, when the second arm 12 is in contact with one end of the chute 110 , the maximum distance that the second arm 12 can move to the other end of the chute 110 is 2mm˜12mm. Therefore, the above-mentioned stabilizer 10 can be applied to photographing equipment of different sizes and weights. For example, when the photographing devices have the same size but different weights, the greater the weight, the greater the distance that the second support arm 12 needs to move to achieve balance.

Further, in this embodiment, on the moving track, the middle part of the chute 110 is square, and the two ends are circular.

Further, in this embodiment, the connector 100 includes a frame body 120 and a bottom cover 130 and a top cover 140 disposed at two ends of the frame body 120 . The frame body 120 , the bottom cover 130 and the top cover 140 enclose and form an accommodating chamber (not shown). The bottom cover 130 is rotatably connected with the first driving member 14 . The sliding slot 110 is disposed on the top cover 140 . One end of the second support arm 12 passes through the chute 110 and is accommodated in the accommodating cavity. Wherein, a plastic sheet 142 for covering the screw 150 is provided on the end of the top cover 140 away from the slide groove 110 . Specifically, in this embodiment, the plastic sheet 142 is a polycarbonate (Polycarbonate, PC) sheet.

It should be noted that, in this embodiment, the second arm 12 is indirectly accommodated in the accommodating cavity through the arm connecting block 300 , and in the following description, “the locking roller 210 is sleeved on the second arm 12 ” , "the outer wall of the second arm 12 is provided with threads" and "the second arm 12 is provided with a mounting groove 12a" are actually "the locking roller 210 is sleeved on the arm connecting block 300", "the arm is connected The outer wall of the block 300 is provided with threads" and "the arm connecting block 300 is provided with a mounting groove 12a". It can be understood that, in other embodiments, when the second support arm 12 is directly accommodated in the accommodating cavity, the following description is applicable.

The first locking member 200 includes a locking roller 210 . The locking roller 210 is sheathed on the second arm 12 . The inner wall of the locking roller 210 is provided with threads, and the outer wall of the second arm 12 is provided with threads. The locking roller 210 can move along the extension direction of the second arm 12 to abut against or be separated from the top cover 140 . When the locking roller 210 abuts against the top cover 140 , the second support arm 12 is relatively fixed to the connector 100 ; when the locking roller 210 is spaced from the top cover 140 , the second support arm 12 can move in the slide groove 110 .

Further, in this embodiment, the first locking member 200 further includes a wear-resistant sheet 220 . The second support arm 12 is provided with a mounting slot 12a. The wear-resistant plate 220 is sleeved on the second support arm 12 , locked in the installation groove 12 a, and located between the top cover 140 and the locking roller 210 . The provision of the wear-resistant sheet 220 can effectively prevent the locking roller 210 from wearing and tearing during relative movement with the second support arm 12 .

As shown in FIG. 2 , in this embodiment, in order to carry the stabilizer 10 conveniently, the stabilizer 10 is designed as a foldable structure. Specifically, in this embodiment, the first arm 11 and the second arm 12 can overlap. When the first support arm 11 overlaps with the second support arm 12 , the clip 13 is located between the first support arm 11 and the second support arm 12 . Therefore, the above-mentioned stabilizer 10 is not only easy to carry, but also can effectively avoid that after being folded, the clip 13 is located on the side of the second arm 12 away from the first arm 11, causing a clip to protrude from the second arm 12. The holder 13 further leads to the problem that the overall thickness of the folded stabilizer 10 is relatively large and it is easy to scratch the holder 13 .

After the stabilizer 10 is folded, the first driving member 14 and the second driving member 15 are likely to rotate freely during carrying, which causes the first arm 11 and the second arm 12 to switch from the overlapped state to the unfolded state. In order to solve the above problems, as shown in Fig. 3 and Fig. 8-10, in this embodiment, a clamping part 13a is provided on the side of the clamping part 13 close to the first support arm 11, and the first support arm 11 is close to the clamping part 13. One side of the piece 13 is provided with a locking groove 11c, and the locking piece 13a is locked in the locking groove 11c, so that the first arm 11 and the second arm 12 are overlapped and relatively fixed.

The clamping piece 13 is rectangular. When shooting, the shooting equipment (such as mobile phones, etc.) clamped on the holder 13 usually needs to be placed horizontally (that is, the viewing angle shown in Figure 6 is used to clamp the shooting device), which requires the holder 13 to be in contact with the shooting device. The side corresponding to the width of the device needs to be equivalent to the width of the shooting device, and the side of the clamping member 13 corresponding to the length of the shooting device can be quite short, as long as it can meet the clamping requirements. In order to make the size of the clamping piece 13 relatively small, the size of the side of the clamping piece 13 corresponding to the width of the shooting device is usually larger than the side of the clamping piece 13 corresponding to the length of the shooting device, that is, the length of the clamping piece 13 is equal to the length of the shooting device. The width of the photographing device corresponds, and the width of the clamping member 13 corresponds to the length of the photographing device.

When the stabilizer is folded, when the clamping component 13 does not need to be rotated in advance, the clamping component 13a can be accurately locked in the slot 11c, which will cause the two sides of the clamping component 13 corresponding to the length of the shooting device to protrude beyond the first The two sides of the support arm 11 cause the folded stabilizer to be wider (even if the two sides of the clip 13 corresponding to the length of the shooting device do not protrude from the two sides of the first support arm 11, at this time it is necessary to increase the width of the first support arm 11 Width will also cause the folded stabilizer to be wider), that is to say, the stabilizer will be bulky, which is not conducive to carrying.

To solve the above problem, in this embodiment, the clamping member 13 can rotate within a range of 360° relative to the second support arm 12 . The clamping piece 13 is rectangular, the long side of the clamping piece 13 is used to correspond to the width of the shooting device, and the wide side of the clamping piece 13 is used to correspond to the length of the shooting device. When the first support arm 11 overlaps with the second support arm 12, the clamping member 13 is located between the first support arm 11 and the second support arm 12, and the long side of the clamping member 13 corresponds to the length of the second support arm 12 , the clamping member 13a is clamped in the clamping groove 11c.

Specifically, as shown in FIG. 3 and FIG. 6, after using the stabilizer shown in FIG. 3 to clamp the shooting device, the clamping part 13 needs to be rotated so that the shooting device on the clamping part 13 can be placed horizontally, that is, as shown in FIG. The state shown in 6 is the specific use state. In Fig. 3, the long side of the clamping part 13 corresponds to the length of the second arm 12. At this time, if the stabilizer in Fig. 3 needs to be folded, the clamping part can be made without rotating the clamping part 13 again. 13a is accurately stuck in the card slot 11c. And in Fig. 6, the long side of clamping part 13 is perpendicular to the long side of second support arm 12, if need to fold the stabilizer in Fig. In this state, the clamping member 13a can be accurately clamped in the clamping groove 11c.

Specifically, in this embodiment, the clamping piece 13 is in a square shape, and the number of clamping pieces 13 a is four, and the four clamping pieces 13 a are respectively arranged at four corners of the clamping piece 13 . The number of clamping slots 11c is also four, and each clamping slot 11c corresponds to a clamping member 13a. The four angles of the clamping member 13 are all fixed, so that the first support arm 11 and the second support arm 12 are overlapped and firmly fixed. It can be understood that, in other embodiments, the number of clamping members 13a is reasonably set according to specific conditions.

In a traditional stabilizer, the second driving member is either directly protruded on the side of the second arm away from the clamping member (at this time, the thickness of the second arm can be thinner, that is, the size of the second arm is smaller ), or be directly accommodated in the second arm (at this time, the thickness of the second arm needs to be equivalent to the thickness of the second driving member, that is, the size of the second arm is smaller), both of which will cause the stabilizer After folding, the thickness is relatively large, so it is not easy to carry.

In order to solve the above problem, as shown in FIG. 3 and FIG. 11 , in this embodiment, a receiving groove 13 b is provided on a side of the clamping member 13 close to the second support arm 12 . One end of the second driving member 12 is located in the accommodating groove 13 b, and the other end is located in the second support arm 12 or protrudes from a side of the second support arm 12 away from the clamping member 13 . An accommodating groove 13b is provided on the clamping part 13 to share part of the volume of the second driving part 12, so that the thickness of the stabilizer 10 after being folded is small and easy to carry while keeping the thickness of the clamping part 13 constant. .

Further, as shown in FIG. 3 and FIG. 8 , in this embodiment, the aforementioned stabilizer 10 further includes an arm connecting block 300 and a second locking member 400 . One end of the arm connecting block 300 can move in the sliding slot 110 , and the other end is rotatably connected with the second support arm 12 . The first locking member 200 is used to relatively fix the arm connecting block 300 and the connecting member 100 . The second locking member 400 is used to relatively fix the second support arm 12 and the arm connecting block 300 . Wherein, the rotation axis of the second support arm 12 relative to the arm connecting block 300 is perpendicular to the second support arm 12 .

Taking the angle of view shown in Figure 3 and Figure 6 as an example, when folding the above-mentioned stabilizer 10, move the second arm 12 so that the second arm 12 rotates 90° around the first arm 11 toward the side where the subject is located , so that the side of the second support arm 12 facing the operator is converted from the side 12b to the side 12c. Then loosen the second locking member 400 so that the second support arm 12 and the connecting block 300 of the arm can be rotated. Turn the second arm 12 so that the second arm 12 rotates around the arm connecting block 300 toward the first arm 11 . If the clamping part 13 is in the state shown in Figure 6, it is necessary to dial the clamping part 13 again, so that the clamping part 13 rotates 90° around the second arm 12, so that the long side of the clamping part 13 is in line with the second arm. The long side of 12 corresponds. Finally, the clamping member 13a is clamped in the clamping groove 11c.

Further, in this embodiment, the end surface of the second arm 12 is sunken to form a U-shaped groove 12d. An end of the arm connecting block 300 away from the sliding slot 110 is located in the U-shaped slot 12d. The second locking member 400 includes a screw rod 410 and a nut 420. The screw rod 410 is passed through the arm connecting block 300, and two ends of the screw rod pass through the two sides of the U-shaped groove 12d respectively. The nut 420 is sheathed on the screw rod 410 . Specifically, in this embodiment, there are two nuts 420 , namely a thumb nut 422 and a locking nut 424 , the screwing nut 422 is disposed on one end of the screw rod 410 , and the locking nut 424 is disposed on the other end of the screw rod 410 .

In this embodiment, the stabilizer 10 is transformed from the folded state to the unfolded state, specifically, the first arm 11 and the second arm 12 are transformed from the overlapped state to the state where the first arm 11 and the second arm 12 are perpendicular .

In order to ensure each rotation of 90°, as shown in FIG. 1 , FIG. 12 and FIG. 13 , in this embodiment, the stabilizer 10 further includes a limiting member 500 . The limiting member 500 includes a fixing sleeve 510 , a pin rod 520 , an elastic member 530 and a toggle member 540 . An end of the second arm 12 close to the first arm 11 has a cavity (not shown in the figure), and the fixing sleeve 510 is disposed in the cavity and fixed on the second arm 12 . The pin rod 520 passes through the fixing sleeve 510 and can move back and forth relative to the fixing sleeve 510 along the extending direction of the second support arm 12 . The elastic member 530 is sheathed on the pin rod 520 , and when the pin rod 520 moves, both ends of the elastic member 530 can abut against the fixing sleeve 510 and the protrusion 522 on the pin rod 520 respectively. The toggle piece 540 is arranged on the second support arm 12, and one end is located in the cavity, and is inserted on one end of the pin rod 520, and is used to toggle the pin rod 520 so that the pin rod 520 moves along the direction of the second support arm 12. The extension direction moves back and forth.

Specifically, in this embodiment, the pin rod 520 is passed through the hole 512 provided on the fixing sleeve 510 . The toggle member 540 passes through the hole 12d on the second arm 12 and the hole 514 on the fixing sleeve 510 in turn, and is locked on the hole 5222 on the protrusion 522 . Wherein, the length of the hole 12 d and the hole 514 in the extending direction of the second arm 12 determines the magnitude of the reciprocating movement of the pin rod 520 along the extending direction of the second arm 12 .

A first hole 310 and a second hole 320 are disposed on the arm connecting block 300 , and the centerline of the first hole 310 is perpendicular to the centerline of the second hole 320 . When the first arm 11 overlaps with the second arm 12, the first hole 310 is used to accommodate an end of the pin 520 close to the first arm 11; when the first arm 11 is perpendicular to the second arm 12, The second hole 320 is used for accommodating an end of the pin rod 520 close to the first support arm 11 .

When it is necessary to convert the stabilizer 10 from the folded state to the unfolded state, the toggle member 540 is moved to drive the pin rod 520 to move away from the arm connecting block 300, so that the pin rod 520 moves out of the first hole 310. When the elastic member 530 is compressed. Then pull the second arm 12 outwards so that the second arm 12 is away from the first arm 11. At this time, the end of the pin 520 close to the arm connecting block 300 can be located at the first hole 310 and the first hole 310 with the arm connecting block 300. The outer walls between the two holes 320 abut against each other (at this moment, the toggle member 540 can be released), and the elastic member 530 is still in a compressed state. When the end of the pin 520 close to the arm connecting block 300 is facing the second hole 320, under the action of the elastic member 530, the end of the pin 520 close to the arm connecting block 300 is accommodated in the second hole 320. At this time, the second support arm 12 is perpendicular to the first support arm 11 .

It can be understood that when a large force is applied to the toggle member 540 , the end of the pin rod 520 close to the arm connecting block 300 may not be in contact with the arm connecting block 300 during the above process. When the second arm 12 is approximately perpendicular to the first arm 11, the toggle member 540 is released, and under the action of the elastic member 530, the end of the pin 520 close to the arm connecting block 300 is accommodated in the second hole 320. middle.

Traditional stabilizers have a single function and can usually only be used as stabilizers. However, after a long-time use of a shooting device (such as a mobile phone), there is usually a problem of insufficient power, and if it cannot be charged in time, the shooting will be terminated. Even if you carry a mobile power supply device such as a power bank, it is not convenient to shoot while charging, and additionally carrying a mobile power device such as a power bank will increase the burden on the user.

In order to solve the above problems, as shown in FIG. 8 , FIG. 14 and FIG. 15 , in this embodiment, the rechargeable battery 16 is arranged in the first arm 11 , specifically in the free end 11 b. The rechargeable battery 16 is provided with a first input interface 16a and a first output interface 16b. The control system 17 includes an angle sensor and a central processing unit 17a. The angle sensor, the first driving element 14 and the second driving element 15 are respectively connected to the central processing unit 17a. The angle sensor is used to detect the angle between the first arm 11 and the second arm 12 . The central processing unit 17a is used for turning on or not turning on the first driving member 14 and the second driving member 15 according to the included angle obtained by the angle sensor.

Use above-mentioned stabilizer 10 to comprise the steps:

Step A: Turn on the power (that is, turn on the stabilizer 10 ), and the angle sensor detects the angle between the first arm 11 and the second arm 12 . Wherein, the angle sensor may be, but not limited to, a photosensitive sensor, a Hall sensor, and the like.

Step B: When the included angle reaches a preset value, the central processing unit 17a is used to turn on the first driving member 14 and the second driving member 15 according to the included angle obtained by the angle sensor. At this moment, the stabilizer 10 can be used for shooting, and a charging cable can be connected between the first output interface 16b and the shooting device (input interface of the shooting device), so that the rechargeable battery 16 can supply power for the shooting device, so that shooting can be performed while charging. That is to say, the stabilizer 10 can not only be used for shooting at this time, but also can be used as a mobile power supply device such as a power bank.

When the included angle does not reach the preset value, the first driving member 14 and the second driving member 15 do not work. At this time, the stabilizer 10 cannot be used for shooting, but can only be used as a mobile power supply device such as a power bank, and the charging cable is connected between the first output interface 16b and the shooting device, so that the rechargeable battery 16 can supply power for the shooting device.

Specifically, in this embodiment, the preset value of the included angle is zero. When the stabilizer 10 is in the folded state, the stabilizer 10 can only be used as a mobile power supply device such as a power bank. And when the stabilizer 10 is unfolded, the stabilizer 10 can be used for shooting, and can also be used as a mobile power supply device such as a power bank. It can be understood that, in other implementation manners, the preset value of the included angle may also be 10°, 90°, and so on.

In the process of shooting while charging, the charging line connecting the first output interface 16b and the shooting device is usually long, which will cause the rotation between the first support arm 11 and the second support arm 12, as well as the connection between the clamping member 13 and the second support arm. Rotation between the arms 12 causes interference. In order to solve this problem, in this embodiment, the clamping member 13 is provided with a second output interface 13c connected to the rechargeable battery 16 . Compared with the first output interface 16b, the second output interface 13c is closer to the shooting device, and a shorter charging line can be used to connect the rechargeable battery 16 and the shooting device, thereby avoiding the longer charging line from interfering with the first arm 11 and the second The rotation between the two arms 12 , and the rotation between the clip 13 and the second arm 12 .

Furthermore, in this embodiment, there are two angle sensors, namely the first angle sensor 17b and the second angle sensor 17c. The first angle sensor 17b and the second angle sensor 17c are respectively connected to the central processing unit 17a. The first angle sensor 17 b is used to detect the angle change of the first support arm 11 , and the second angle sensor 17 c is used to detect the angle change of the second support arm 12 . The central processing unit 17a is used to obtain the included angle according to the angle change of the first arm 11 and the angle change of the second arm 12 .

When the first driver 14 and the second driver 15 are turned on, the central processing unit 17a guides the first driver 14 to work according to the angle change of the first arm 11, and guides the second driver according to the angle change of the second arm 12. The driving part 15 works.

Further, as shown in FIG. 6 , in this embodiment, the clamping member 13 includes a main body (not shown in the figure) and two splints 13d provided on the main body. The two splints 13d are arranged facing each other, and the splint 13d is rotatably connected to the body through an elastic element (not shown), so as to be accommodated in the escape groove 13e provided on the body. Moreover, the distance between the two clamping plates 13d is adjustable, so that it can be used to clamp shooting equipment of different sizes.
