Description

Technical Field

[0001] This utility model relates to the field of stabilizer technology, and in particular to a stabilizer locking structure and a stabilizer having the same. Background Technology

[0002] With advancements in mobile phone photography quality and improvements in stabilizer materials and design, stylish, compact, and lightweight handheld stabilizers have emerged. Handheld stabilizers effectively reduce the adverse effects of operator body shaking during shooting, physically compensating for bumps and shakiness during mobile phone shooting, and ensuring clear and beautiful images.

[0003] Currently, the most common handheld stabilizers on the market fall into two main categories: two-axis stabilizers and three-axis stabilizers. Each axis corresponds to a rotating arm, and each rotating arm is equipped with a corresponding motor. The motor controls the rotation of the clamping arm, thereby controlling the rotation of shooting devices such as cameras and mobile phones clamped on one of the rotating arms to adjust the shooting angle. When the motor is not working, it is generally necessary to restrict the movement of each clamping arm to reduce the overall size of the product and facilitate storage. Therefore, locking devices are also set on the clamping arms. However, the existing locking structures are complex and costly. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a stabilizer locking structure and a stabilizer having the same. The stabilizer locking structure consists of a fixed ring, a first rotating arm, a lever, and a locking key. Locking is achieved by the lever's limiting protrusion cooperating with the fixed ring's limiting groove. Moving the locking key causes it to move and squeeze the pressing part, thereby unlocking the first rotating arm. It has the advantages of simple structure, reliable locking, and convenient operation.

[0005] According to a first aspect embodiment of the present invention, a stabilizer locking structure includes a fixed ring, a first rotating arm, a lever, and a locking key. The fixed ring has a limiting groove. One end of the first rotating arm is rotatably connected to the fixed ring. The middle portion of the lever is rotatably connected to the first rotating arm, and both sides are respectively provided with limiting protrusions and pressing portions. When the limiting protrusions are inserted into the limiting grooves, they restrict the rotation of the first rotating arm relative to the fixed ring. The locking key is movably disposed on the first rotating arm and abuts against the pressing portions. Moving the locking key causes it to press against the pressing portions, thereby causing the lever to rotate, the limiting protrusions to disengage from the limiting grooves, and the locking of the fixed ring to the first rotating arm to be released.

[0006] According to the stabilizer locking structure of the first aspect embodiment of this utility model, the following beneficial effects can be achieved: The core structure consists of a fixed ring, a first rotating arm, a lever, and a locking key. It eliminates the need for complex transmission components or electronic control elements, simplifying the production process and assembly flow, reducing material costs and manufacturing difficulty, and meeting the design requirements of lightweight and miniaturized handheld stabilizers. When the limiting protrusion of the lever is inserted into the limiting groove of the fixed ring, a mechanical rigid lock is formed, effectively restricting the rotation of the first rotating arm relative to the fixed ring. This ensures that the positions of each rotating arm are fixed when the stabilizer is stored or not in operation, preventing equipment collisions or shooting angle deviations caused by shaking, thus improving safety and stability. By moving the locking key, the locking key presses against the pressing part of the lever, quickly driving the lever to rotate and causing the limiting protrusion to disengage from the limiting groove, achieving unlocking. This operation can be completed by pushing the locking key with only one finger, conforming to ergonomic design and suitable for users to quickly switch between locked / unlocked states during shooting, improving efficiency. The lever mechanism amplifies the operating force using mechanical principles, making unlocking require less force and easier to operate, especially suitable for long-term handheld shooting scenarios.

[0007] According to some embodiments of the present invention, a rotating groove is provided on the first rotating arm, and a rotating shaft is formed by protruding from the middle of the lever to both sides. The rotating shaft is rotatably disposed in the rotating groove, so that the lever is rotatably connected to the first rotating arm.

[0008] According to some embodiments of the present invention, the sidewall of the extrusion part is an inclined guide surface; the locking key moves along the inclined guide surface to the top wall of the extrusion part to press the extrusion part.

[0009] According to some embodiments of the present invention, the surface of the locking key that abuts against the pressing part is also an inclined guide surface, and the two inclined guide surfaces of the pressing part and the locking key are in close contact with each other.

[0010] According to some embodiments of the present invention, it further includes a limiting part, which is rotatably connected to the lever, and the limiting protrusion is disposed on the limiting part.

[0011] According to some embodiments of the present invention, the lever is provided with a rotating hole at the end of the limiting protrusion, and a rotating rod is provided on the limiting part.

[0012] According to some embodiments of this utility model, it also includes an elastic element, one end of which is fixedly disposed, and the other end abuts against the limiting protrusion side of the lever. After the locking key releases the pressure on the squeezing part, the elastic element pushes the lever to rotate so that the limiting protrusion is inserted into the limiting groove.

[0013] According to some embodiments of the present invention, a guide groove is provided on the first rotating arm, and the locking key is embedded in the guide groove, which can move along the guide groove to press the squeezing part.

[0014] According to some embodiments of the present invention, the guide groove is provided with two limiting blocks along the moving direction of the locking key, and the locking key is provided with a travel protrusion, which is disposed between the two limiting blocks to limit the maximum distance the locking key can move.

[0015] A stabilizer according to a second aspect of the present invention includes a handle, a stabilizer locking structure according to a first aspect of the present invention, and a second rotating arm, wherein a fixing ring is disposed on the second rotating arm, and the other end of the first rotating arm is rotatably connected to the handle.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] The following is for reference. Figures 1 to 8 This invention describes a stabilizer locking structure and a stabilizer according to embodiments of the present invention.

[0034] According to the first aspect of the present invention, the stabilizer locking structure includes a fixed ring 100, a first rotating arm 210, a lever 500, and a locking key 300. The fixed ring 100 has a limiting groove 110. One end of the first rotating arm 210 is rotatably connected to the fixed ring 100. The middle part of the lever 500 is rotatably connected to the first rotating arm 210, and both sides are provided with limiting protrusions 511 and pressing parts 520. When the limiting protrusions 511 are inserted into the limiting groove 110, they restrict the rotation of the first rotating arm 210 relative to the fixed ring 100. The locking key 300 is movably disposed on the first rotating arm 210 and abuts against the pressing part 520. Moving the locking key 300 causes the locking key 300 to press the pressing part 520, thereby causing the lever 500 to rotate, causing the limiting protrusions 511 to disengage from the limiting groove 110, and releasing the locking of the fixed ring 100 on the first rotating arm 210.

[0035] For example Figure 3 and Figure 4 As shown, the stabilizer locking structure mainly consists of a fixed ring 100, a first rotating arm 210, a lever 500, and a locking key 300. The fixed ring 100 has a limiting groove 110 on its outer peripheral wall. One end of the first rotating arm 210 is rotatably connected to the fixed ring 100, allowing it to rotate relative to the fixed ring 100. The lever 500 is a long, plate-like structure, with its middle section rotatably connected to the first rotating arm 210. A limiting protrusion 511 is provided at one end of the lever 500, and a pressing part 520 is formed at the other end. When the limiting protrusion 511 is inserted into the limiting groove 110 of the fixed ring 100, it restricts the rotation of the first rotating arm 210 relative to the fixed ring 100. The locking key 300 is a block-shaped structure, slidably mounted on the first rotating arm 210, and one end of the locking key 300 abuts against the side of the pressing part 520.

[0036] When the first rotating arm 210 needs to be locked, the limiting protrusion 511 of the lever 500 will insert into the limiting groove 110 of the fixing ring 100 under its own weight or external force, and fix the first rotating arm 210 by mechanical rigidity. When unlocking is required, the locking key 300 is pushed to move along the first rotating arm 210, so that the locking key 300 presses the pressing part 520, causing the lever 500 to rotate around the central axis, thereby allowing the limiting protrusion 511 to disengage from the limiting groove 110, and the first rotating arm 210 can rotate freely.

[0037] Furthermore, multiple limiting grooves 110 are provided along the circumference of the fixing ring 100. For example, as shown in the figure, multiple limiting grooves 110 are evenly distributed along the circumference of the fixing ring 100, and the shape and depth of each limiting groove 110 are consistent. The limiting protrusion 511 of the locking key 300 can cooperate with any one of the limiting grooves 110 to lock the rotating arm at multiple angular positions.

[0038] The multiple limiting grooves 110 provide the rotating arm with the flexibility to adjust to multiple angles. Users can lock the rotating arm in different positions according to shooting needs, expanding the applicable scenarios of the stabilizer.

[0039] According to the stabilizer locking structure of the first aspect embodiment of this utility model, the following beneficial effects can be achieved: The core structure consists of a fixed ring 100, a first rotating arm 210, a lever 500, and a locking key 300. It eliminates the need for complex transmission components or electronic control elements, simplifying the production process and assembly flow, reducing material costs and manufacturing difficulty, and meeting the design requirements of lightweight and miniaturized handheld stabilizers. When the limiting protrusion 511 of the lever 500 is inserted into the limiting groove 110 of the fixed ring 100, a mechanical rigid lock is formed, effectively restricting the rotation of the first rotating arm 210 relative to the fixed ring 100. This ensures that the positions of each rotating arm are fixed when the stabilizer is stored or not in operation, preventing equipment collisions or shooting angle shifts due to shaking, thus improving safety and stability. By moving the locking key 300 to press the squeezing part 520 of the lever 500, the lever 500 can be quickly driven to rotate, causing the limiting protrusion 511 to disengage from the limiting groove 110, thereby unlocking the stabilizer. The operation can be completed with just one finger pushing the lock button 300, which is ergonomically designed and allows users to quickly switch between locked and unlocked states during shooting, improving efficiency. The lever 500 mechanism uses mechanical principles to amplify the operating force, making unlocking easier and more suitable for long-term handheld shooting scenarios.

[0040] In some specific embodiments of this utility model, a rotating groove 211 is provided on the first rotating arm 210, and a rotating shaft 530 is formed by protruding from the middle of the lever 500 to both sides. The rotating shaft 530 is rotatably disposed in the rotating groove 211, so that the lever 500 is rotatably connected to the first rotating arm 210.

[0041] For example Figure 5 and Figure 6As shown, at the connection point between the first rotating arm 210 and the lever 500, an elongated rotating groove 211 is provided, the length direction of which is perpendicular to the length direction of the first rotating arm 210. The middle part of the lever 500 protrudes to both sides, forming a cylindrical rotating shaft 530, the diameter of which is adapted to the width of the rotating groove 211. The rotating shaft 530 is embedded in the rotating groove 211 and can rotate freely within it, thus achieving a rotating connection between the lever 500 and the first rotating arm 210.

[0042] The mating structure of the rotating groove 211 and the rotating shaft 530 provides a stable fulcrum for the lever 500. This connection method is not only simple in structure and easy to assemble, but also ensures that the lever 500 remains stable during rotation, reducing swaying and offset, thereby improving the reliability and stability of the locking structure.

[0043] In some specific embodiments of this utility model, the side wall of the extrusion part 520 is an inclined guide surface 521; the locking key 300 moves along the inclined guide surface 521 to the top wall of the extrusion part 520 to press the extrusion part 520.

[0044] For example Figure 6 As shown, the sidewall of the pressing part 520 is designed as an inclined guide surface 521, which forms a certain angle with the length direction of the lever 500. When the locking key 300 moves along the guide groove 213 on the first rotating arm 210, it will gradually move upward along the inclined guide surface 521 of the pressing part 520, and finally reach the top wall of the pressing part 520, thereby pressing the pressing part 520.

[0045] The inclined guide surface 521 of the pressing part 520 guides the movement of the locking key 300, making the movement of the locking key 300 smoother and reducing frictional resistance. At the same time, this inclined design can convert the horizontal movement force of the locking key 300 into vertical pressing force, thereby reducing the operating force required to unlock and making it easier for the user to operate.

[0046] In some specific embodiments of this utility model, the surface of the locking key 300 that abuts against the pressing part 520 is also an inclined guide surface 521, and the two inclined guide surfaces 521 of the pressing part 520 and the locking key 300 fit together.

[0047] For example Figure 7As shown, the surface of the locking key 300 that abuts against the pressing part 520 is also designed as an inclined guide surface 521. The inclined guide surface 521 has the same angle as the inclined guide surface 521 of the pressing part 520, and the two inclined guide surfaces 521 are in close contact with each other. When the locking key 300 moves, relative sliding will occur between the two inclined guide surfaces 521, thereby realizing the rotation of the pressing part 520.

[0048] The two mutually fitting inclined guide surfaces 521 enable a more uniform and stable force transmission between the locking key 300 and the pressing part 520. This design not only further reduces the operating force but also prevents the locking key 300 from jamming or shifting during movement, thus improving the smoothness and reliability of the unlocking operation.

[0049] In some specific embodiments of this utility model, a limiting part 510 is also included, which is rotatably connected to the lever 500, and a limiting protrusion 511 is disposed on the limiting part 510.

[0050] For example Figure 4 and Figure 6 As shown, it also includes a limiting part 510, which is rotatably connected to the lever 500. A limiting protrusion 511 is provided at the end of the limiting part 510, and the limiting protrusion 511 faces the limiting groove 110 of the fixing ring 100.

[0051] The setting of the limiting part 510 makes the limiting protrusion 511 and the lever 500 rotatably connected, which can ensure that the limiting protrusion 511 can always be aligned with the limiting groove 110 when the lever 500 rotates, so that the limiting protrusion 511 can be accurately inserted into the limiting groove 110 to lock the first rotating arm 210.

[0052] In some specific embodiments of this utility model, the lever 500 is provided with a rotating hole 540 at one end of the limiting protrusion 511, and a rotating rod 512 is provided on the limiting part 510. The rotating hole 540 is sleeved on the rotating rod 512 so that the limiting part 510 and the lever 500 are rotatably connected.

[0053] For example Figure 4 and Figure 6 As shown, the lever 500 has a circular rotating hole 540 at one end of the limiting protrusion 511. A rotating rod 512 is provided on the limiting part 510, and the rotating rod 512 is inserted into the rotating hole 540 to prevent the rotating rod 512 from falling out of the rotating hole 540. This achieves a rotating connection between the limiting part 510 and the lever 500.

[0054] The mating structure of the rotating hole 540 and the rotating rod 512 is simple and reliable, ensuring the rotational flexibility between the limiting part 510 and the lever 500.

[0055] In some specific embodiments of this utility model, an elastic element 560 is also included. One end of the elastic element 560 is fixedly set, and the other end abuts against one side of the limiting protrusion 511 of the lever 500. After the locking key 300 releases the pressure on the squeezing part 520, the elastic element 560 pushes the lever 500 to rotate so that the limiting protrusion 511 is inserted into the limiting groove 110.

[0056] For example Figure 4 and Figure 6 As shown, the locking structure also includes an elastic element 560. One end of the elastic element 560 is fixed to the inner bottom wall of the first rotating arm 210, and the other end abuts against one side of the limiting protrusion 511 of the lever 500. When the locking key 300 releases the pressure on the pressing part 520, the elastic element 560 generates a spring force, pushing the lever 500 to rotate, causing the limiting protrusion 511 to insert into the limiting groove 110 of the fixing ring 100.

[0057] The elastic element 560 enables the locking structure to have an automatic reset function. When the user releases the locking key 300, the elastic element 560 automatically pushes the lever 500 to reset, causing the limiting protrusion 511 to re-insert into the limiting groove 110, thus achieving locking. This design eliminates the need for manual reset by the user, improving ease of use while ensuring timely and reliable locking.

[0058] Furthermore, the first rotating arm 210 is provided with a guide post 212, the lever 500 is provided with a matching guide hole 550, and one end of the elastic element 560 is sleeved on the guide post 212, and the other end is provided in the guide hole 550.

[0059] For example Figure 4 and Figure 6 As shown, a guide post 212 is fixed to the bottom inner side of the first rotating arm 210. A guide hole 550 adapted to the guide post 212 is provided on the lever 500. The guide post 212 and the guide hole 550 are arranged opposite to each other. One end of the elastic member 560 is sleeved outside the guide post 212, and the other end extends into the guide hole 550.

[0060] The cooperation between the guide post 212 and the guide hole 550 provides linear motion constraint for the elastic element 560. When the user releases the locking key 300, the elastic element 560 will automatically push the lever 500 to reset, so that the limiting protrusion 511 is re-inserted into the limiting groove 110 to achieve locking.

[0061] In some specific embodiments of this utility model, a guide groove 213 is provided on the first rotating arm 210, and a locking key 300 is embedded in the guide groove 213, which can move along the guide groove 213 to press the squeezing part 520.

[0062] For example Figure 5As shown, a long strip-shaped guide groove 213 is provided on the first rotating arm 210, and the length direction of the guide groove 213 is consistent with the moving direction of the locking key 300. The locking key 300 is embedded in the guide groove 213 and can move along the guide groove 213. The two side walls of the guide groove 213 limit the locking key 300 to prevent the locking key 300 from deviating during movement.

[0063] The guide groove 213 provides guidance and limit for the movement of the locking key 300, ensuring that the locking key 300 moves in a predetermined direction and preventing the locking key 300 from shaking or deviating during movement, thereby improving the accuracy and stability of the unlocking operation.

[0064] In some specific embodiments of this utility model, the guide groove 213 is provided with two limiting blocks 214 along the moving direction of the locking key 300, and the locking key 300 is provided with a travel protrusion 310. The travel protrusion 310 is located between the two limiting blocks 214 to limit the maximum distance of movement of the locking key 300.

[0065] For example Figure 5 and Figure 7 As shown, a limit block 214 is provided at each end of the guide groove 213 along the moving direction of the locking key 300. The locking key 300 is provided with a travel protrusion 310, which is located between the two limit blocks 214. When the locking key 300 moves to the limit position, the travel protrusion 310 will contact the limit block 214, thereby limiting the maximum distance of movement of the locking key 300.

[0066] The cooperative structure of the limit stop 214 and the travel protrusion 310 can accurately limit the movement distance of the locking key 300, prevent the locking key 300 from moving excessively, ensure that the locking key 300 works within a safe travel range, and improve the reliability and service life of the locking structure.

[0067] In some specific embodiments of the present invention, the stabilizer according to the second aspect of the present invention includes a handle 400, a stabilizer locking structure and a second rotating arm 220 according to the first aspect of the present invention, a fixing ring 100 is disposed on the second rotating arm 220, and the other end of the first rotating arm 210 is rotatably connected to the handle 400.

[0068] According to the second aspect embodiment of the present invention, the stabilizer, through its configuration, achieves at least the following beneficial effects: the stabilizer forms a compact structure through the linkage of the fixing ring 100, the first rotating arm 210, the handle 400, and the second rotating arm 220. The locking structure reliably locks and unlocks the position of the rotating arms, facilitating quick adjustment of the shooting angle by the user. Simultaneously, the fixed position of each rotating arm in the locked state reduces the size of the device, making it convenient for storage and carrying, and perfectly meeting the needs of a portable stabilizer with multi-angle adjustment.

[0069] Furthermore, the fixing ring 100 serves as a rotation node, connecting different components of the stabilizer. Integrating the locking structure into the overall stabilizer design enables flexible linkage and reliable locking between components, allowing the stabilizer to quickly switch between folded storage and unfolded working states, balancing portability and functionality.

[0070] Furthermore, it also includes a first drive motor, which is used to drive the first rotating arm 210 to rotate relative to the fixed ring 100.

[0071] By driving the first rotating arm 210 to rotate relative to the fixed ring 100 with the first drive motor, manpower can be saved.

[0072] Furthermore, it also includes a third rotating arm 230, which is rotatably connected to the second rotating arm 220. The third rotating arm 230 is used to clamp external devices or is provided with a clamping part 231 for clamping external devices.

[0073] For example Figure 1 As shown, the stabilizer also includes a third rotating arm 230, the other end of which is rotatably connected to the third rotating arm 230, forming a three-axis rotating structure. The end of the third rotating arm 230 is provided with a clamping part 231 for fixing external devices such as mobile phones and cameras. Each rotating arm has an independent locking structure, allowing for individual locking or unlocking.

[0074] The three-stage rotating arm structure gives the stabilizer more flexible attitude adjustment capabilities, which can adapt to the equipment balance requirements in complex shooting scenarios; the diverse design of the clamping part 231 enhances the stabilizer's versatility and meets the needs of users with multiple devices.

[0075] It will be readily apparent to those skilled in the art that the locking structure of this application may also be disposed between the first rotating arm 210 and the handle 400, or between the second rotating arm 220 and the third rotating arm 230; the above-mentioned adjustments to the position of the locking structure are readily apparent and require no inventive effort, and should all fall within the protection scope of this application.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
