Description

Technical Field

[0001] This utility model relates to the field of gimbal technology, and more specifically, to a servo gimbal. Background Technology

[0002] In applications such as video surveillance, drone aerial photography, and mobile photography, the rapid deployment and installation of camera equipment is a key link to ensure shooting efficiency and seize fleeting shooting opportunities. However, the camera equipment support devices widely used in the market generally adopt the traditional screw fastening method, which requires operators to use professional tools to tighten and loosen multiple screws. It is also easy to damage the equipment or make the installation unstable due to improper operation, which seriously affects the efficiency and image quality of the photography work.

[0003] In the fields of professional video production and mobile surveillance, the ability of equipment to be flexibly converted and quickly adjusted is directly related to the quality and timeliness of work results. Especially in time-sensitive situations such as news reporting, emergency rescue, and outdoor exploration, the connection structure of traditional support devices has problems such as difficult positioning, cumbersome disassembly and assembly, and strong dependence on tools. In addition, the existing connection methods have high technical requirements for operators, which is not conducive to the use of photography enthusiasts and non-professionals, and also limits the application of photography equipment in a wider range of scenarios. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a servo gimbal to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a servo gimbal, comprising a gimbal body, wherein a mounting mechanism is provided at the bottom end of the gimbal body, the mounting mechanism comprising a fixing frame, a screw, a fixing plate, a connecting rod, and a positioning mechanism, the fixing frame being connected to the bottom end of the gimbal body, the screw being threadedly connected to the fixing frame, the fixing plate being disposed on one side of the fixing frame, the connecting rod rotating within the fixing plate and being fixedly connected to the screw, the positioning mechanism comprising a fixing sleeve, a mounting ring, sliding holes, a positioning block, an abutting rod, an abutting sleeve, and a positioning groove, the fixing sleeve being fixed to the outer wall of the fixing plate, the mounting ring being fixed to the outer wall of the connecting rod, multiple sets of sliding holes being provided distributed within the mounting ring, the positioning block being movable within multiple sets of sliding holes, the abutting rod being fixed to the top of multiple sets of positioning blocks and being slidably connected to the mounting ring, the abutting sleeve being slidably mounted on the outer wall of the connecting rod, multiple sets of positioning grooves being provided distributed within the fixing sleeve, and a throttle being fixedly provided at the top end of the connecting rod.

[0008] The present invention is further provided that a limiting rod is fixedly provided on the inner side of the fixing plate. The limiting rod is provided in multiple sets and is slidably connected to the fixing frame. The multiple sets of limiting rods ensure that the fixing plate moves in a precise straight line along the fixing frame without deflection, which improves the uniformity and stability of the clamping force, and simplifies the operation process to make the installation more convenient.

[0009] The present invention is further configured such that the outer walls of the multiple sets of positioning blocks and the positioning grooves are all arc-shaped and abut each other. The arc-shaped design increases the contact area and forms a natural positioning guide, enabling the positioning blocks to slide smoothly into the positioning grooves and achieve precise positioning. At the same time, it reduces local stress concentration and extends the service life of the components.

[0010] The present invention is further configured such that a tension spring is connected between the outer wall of the multiple sets of positioning blocks and the inner wall of the sliding hole. The tension spring provides a continuous return force to the positioning block, so that the positioning block can automatically reset to the ready state after unlocking. At the same time, it provides an appropriate preload in the locked state to prevent loosening caused by vibration or accidental collision.

[0011] The present invention is further provided that the outer wall of the connecting rod is provided with guide strips, and multiple sets of guide strips are provided, all of which are slidably connected to the abutment sleeve. The guide strips form a precise axial guide track, ensuring that the abutment sleeve can only move along the axial direction and will not rotate, thereby improving the operating accuracy and reliability of the locking mechanism and reducing wear between components.

[0012] The present invention is further configured such that a limiting mechanism is provided on the outer wall of the connecting rod. The limiting mechanism includes a sliding rod, a limiting block, a rotating sleeve, an arc-shaped hole, and an unlocking hole. Multiple sets of sliding rods are fixed to the top surface of the abutment sleeve, and the limiting block is fixed to the top of multiple sets of sliding rods. The rotating sleeve rotates on the outer wall of the connecting rod, and multiple sets of arc-shaped holes are distributed on the outer wall of the rotating sleeve. The unlocking hole is located at one end of the multiple sets of arc-shaped holes. This limiting mechanism locks and unlocks the position of the abutment sleeve by rotating the rotating sleeve. The design of the arc-shaped hole and the unlocking hole makes the operation more intuitive. The locking state can be changed by simply rotating the sleeve without the need for any tools.

[0013] The present invention is further configured such that all of the multiple sets of limiting blocks are configured as I-shaped. The I-shaped structure increases the contact area between the limiting block and the rotating sleeve, improving the locking strength and stability. At the same time, the I-shaped structural design enhances the rigidity of the limiting block itself, making it less prone to deformation after long-term use and ensuring the reliability of the locking mechanism.

[0014] This utility model is further configured such that each of the multiple sets of sliding rods has a return spring on its outer wall, the top of each of the multiple sets of return springs is fixedly connected to an abutment sleeve, the bottom of each of the multiple sets of return springs is fixedly provided with a connecting ring, the bottom of each of the multiple sets of connecting rings is fixedly provided with an arc-shaped slider, the outer wall of the rotating sleeve has an annular groove, and the multiple sets of arc-shaped sliders slide in the annular groove. The combination design of the return spring and the arc-shaped slider realizes the automatic reset function after unlocking. The annular groove restricts the rotating sleeve to rotate only around the axis without axial displacement, ensuring the stability of the locking mechanism and the smoothness of operation, and greatly improving the ease of use of the equipment in scenarios of frequent disassembly and assembly.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a servo gimbal with the following advantages:

[0017] 1. The mounting mechanism adopts a collaborative design of screw, fixed frame, and fixed plate. By rotating the connecting rod, the screw is precisely controlled, allowing the fixed plate to move precisely linearly along the limit rod. This ensures that the camera equipment is firmly fixed to the pan-tilt unit, significantly improving installation convenience. It is particularly suitable for time-sensitive situations such as field shooting and emergency monitoring setup. This integrated mounting mechanism solves the problems of difficult positioning and cumbersome disassembly and assembly in traditional connection methods, making operation simpler and more intuitive. It greatly reduces the technical skill requirements for operators and expands the application scenarios of the camera equipment.

[0018] 2. The positioning mechanism, through the ingenious cooperation of the fixing sleeve, mounting ring, and positioning block, combined with the coordinated work of the abutment rod, abutment sleeve, and positioning groove, achieves precise locking of the connecting rod's rotation angle. This positioning mechanism allows operators to perceive clear locking feedback, avoiding problems such as over-rotation or incomplete locking, while also reducing mechanical wear after long-term use. The overall structure is compact and ingenious, ensuring connection stability while also creating conditions for quick disassembly. It is particularly suitable for applications in work scenarios such as news reporting and emergency rescue that require frequent equipment adjustments, significantly improving work efficiency and equipment lifespan.

[0019] 3. The limiting mechanism adopts a combination design of sliding rod, limiting block, and rotating sleeve. Through the ingenious configuration of arc-shaped holes and unlocking holes, reliable locking and quick release of the connection state are achieved. The I-shaped limiting block provides a larger contact area and higher structural strength, ensuring the firmness of the lock. The reset spring and connecting ring provide an automatic reset function for the unlocking operation, making the operation simpler. No tools are needed; locking and unlocking can be completed simply by pushing, pulling, and rotating, greatly reducing operational complexity and time costs. It can maintain a stable locked state in high-vibration environments such as moving vehicles or aerial drones, solving the industry pain point of traditional connection methods being prone to loosening after long-term use, and providing more reliable equipment support for photography work.

[0029] Please see Figures 1-5 A servo gimbal includes a gimbal body 1. A mounting mechanism is provided at the bottom of the gimbal body 1. The mounting mechanism includes a fixing frame 2, a screw 3, a fixing plate 4, a connecting rod 5, and a positioning mechanism. The fixing frame 2 is connected to the bottom of the gimbal body 1. The screw 3 is threaded into the fixing frame 2. The fixing plate 4 is located on one side of the fixing frame 2. The connecting rod 5 rotates within the fixing plate 4 and is fixedly connected to the screw 3. The positioning mechanism includes a fixing sleeve 6, a mounting ring 7, sliding holes 8, positioning blocks 9, abutting rods 10, abutting sleeves 11, and positioning grooves 12. The fixing sleeve 6 is fixed to the outer wall of the fixing plate 4. The mounting ring 7 is fixed to the outer wall of the connecting rod 5. Multiple sets of sliding holes 8 are distributed within the mounting ring 7. The positioning blocks 9 move within the multiple sets of sliding holes 8. The abutting rod 10 is fixed to the top of the multiple sets of positioning blocks 9 and slidably connected to the mounting ring 7. The abutting sleeve 11 slides on the outer wall of the connecting rod 5. Multiple sets of positioning grooves 12 are distributed within the fixing sleeve 6. A throttle 13 is fixedly provided at the top of the connecting rod 5.

[0030] A limiting rod 14 is fixedly provided on the inner side of the fixed plate 4. Multiple sets of limiting rods 14 are provided and are slidably connected to the fixed frame 2. The multiple sets of limiting rods 14 form a guide structure between the fixed plate 4 and the fixed frame 2, ensuring that the fixed plate 4 can only move in a straight line along the predetermined trajectory without deflection, thereby improving the stability and accuracy during the clamping process.

[0031] The outer walls of multiple positioning blocks 9 and positioning grooves 12 are all set to be arc-shaped and abut against each other. The arc-shaped positioning blocks 9 and positioning grooves 12 form surface contact, which increases the contact area and provides natural positioning guidance, so that the positioning blocks 9 can slide smoothly into the positioning grooves 12 and achieve precise positioning, while reducing local stress concentration.

[0032] Multiple sets of positioning blocks 9 are connected to the outer wall of the sliding hole 8 with tension springs 15. Under normal conditions, tension springs 15 apply a continuous return force to the positioning blocks 9, so that the positioning blocks 9 can automatically return to the initial position after unlocking. At the same time, they provide appropriate preload force in the locked state to prevent loosening caused by vibration or collision.

[0033] The outer wall of the connecting rod 5 is provided with guide bars 16. Multiple sets of guide bars 16 are provided and all are slidably connected to the abutment sleeve 11. The multiple sets of guide bars 16 and the abutment sleeve 11 form a keyway-type fit structure, which restricts the abutment sleeve 11 to move only along the axial direction and not to rotate, ensuring that the movement trajectory of the abutment sleeve 11 is precise and controllable, and improving the operating accuracy of the locking mechanism.

[0034] The outer wall of the connecting rod 5 is provided with a limiting mechanism, which includes a sliding rod 17, a limiting block 18, a rotating sleeve 19, an arc-shaped hole 20, and an unlocking hole 21. The sliding rod 17 is provided with multiple sets fixed to the top surface of the abutment sleeve 11, the limiting block 18 is fixed to the top of the multiple sets of sliding rods 17, the rotating sleeve 19 rotates on the outer wall of the connecting rod 5, the arc-shaped hole 20 is provided with multiple sets distributed on the outer wall of the rotating sleeve 19, and the unlocking hole 21 is provided at one end of the multiple sets of arc-shaped holes 20. By rotating the rotating sleeve 19, the relative position of the arc-shaped hole 20 and the unlocking hole 21 is changed, controlling whether the limiting block 18 can pass through the unlocking hole 21, thereby realizing the locking and unlocking of the position of the abutment sleeve 11. The whole process can be completed with just a simple rotation.

[0035] All sets of limit blocks 18 are set in the shape of an I-beam. The I-beam structure of the limit blocks 18 increases the contact area with the rotating sleeve 19, which improves the locking strength and stability. At the same time, the I-beam design enhances the rigidity of the limit blocks 18 themselves, making them less prone to deformation after long-term use and ensuring the reliability of the locking mechanism.

[0036] Each set of slide rods 17 has a return spring 22 on its outer wall. The top of each set of return springs 22 is fixedly connected to an abutment sleeve 11. Each set of return springs 22 has a connecting ring 23 fixedly connected to its bottom end. Each set of connecting rings 23 has an arc-shaped slider 24 fixedly connected to its bottom end. The outer wall of the rotating sleeve 19 has an annular groove 25. Each set of arc-shaped sliders 24 slides in the annular groove 25. The return spring 22 provides an automatic reset function after unlocking. The sliding of the arc-shaped sliders 24 in the annular groove 25 ensures that the rotating sleeve 19 can only rotate around the axis without axial displacement. The connecting ring 23 transmits the reset force to the entire limit system, forming a coordinated whole mechanism.

[0037] In this embodiment, when the camera needs to be installed, the camera is placed between the mounting bracket 2 and the mounting plate 4. Rotating the handle 13 drives the connecting rod 5 to rotate, which in turn drives the screw 3 to rotate and engages with the mounting bracket 2 through a threaded connection. This causes the screw 3 to move the mounting plate 4. The mounting plate 4 slides along the mounting bracket 2 via multiple sets of limiting rods 14, thereby clamping the mounting bracket 2 and the mounting plate 4 against the outer wall of the camera. Then, the abutment sleeve 11 is pushed to slide along multiple sets of guide strips 16 and abut against the top of multiple sets of abutment rods 10. The multiple sets of abutment rods 10 push the positioning block 9. The screw 3 slides along the sliding hole 8 and abuts against the positioning groove 12. At the same time, multiple sets of positioning blocks 9 stretch the tension spring 15. At this time, the abutment sleeve 11 drives multiple sets of sliding rods 17 to move along the unlocking hole 21. When multiple sets of limiting blocks 18 move into the unlocking hole 21, the rotating sleeve 19 rotates counterclockwise. At this time, the abutment sleeve 11 stretches multiple sets of reset springs 22. When the rotating sleeve 19 rotates, multiple sets of arc-shaped sliders 24 slide along the annular groove 25, so that multiple sets of limiting blocks 18 slide into the arc-shaped hole 20. The outer walls of multiple sets of I-shaped limiting blocks 18 abut against the outer wall of the rotating sleeve 19, thus completing the positioning of the screw 3.

[0038] More specifically, when the camera needs to be disassembled, rotating the rotating sleeve 19 clockwise moves multiple sets of limiting blocks 18 into the unlocking hole 21, releasing the limiting of the abutment sleeve 11. Multiple sets of reset springs 22 pull the abutment sleeve 11 to release the abutment of multiple sets of abutment rods 10. Multiple sets of tension springs 15 pull the positioning block 9 out of the positioning groove 12, releasing the positioning of the connecting rod 5. Rotating the handle 13 drives the screw 3 to rotate through the connecting rod 5, so that the screw 3 and the fixing frame 2 are threaded together, so that the fixing plate 4 is released from clamping the outer wall of the camera, and the camera can be disassembled.

[0039] In summary, during the use or operation of the overall equipment: When the camera needs to be installed, place the camera between the mounting bracket 2 and the mounting plate 4. Rotate the handle 13 to drive the connecting rod 5 to rotate. The connecting rod 5 drives the screw 3 to rotate and engages with the mounting bracket 2 through a threaded connection. This causes the screw 3 to move the mounting plate 4. The mounting plate 4 slides along the mounting bracket 2 via multiple sets of limiting rods 14, thereby clamping the mounting bracket 2 and the mounting plate 4 against the outer wall of the camera. Then, push the abutment sleeve 11 to slide along multiple sets of guide bars 16 and abut against the top of multiple sets of abutment rods 10. The multiple sets of abutment rods 10 push... The positioning block 9 slides along the sliding hole 8 and abuts against the positioning groove 12. At the same time, multiple sets of positioning blocks 9 stretch the tension spring 15. At this time, the abutting sleeve 11 drives multiple sets of sliding rods 17 to move along the unlocking hole 21. When multiple sets of limiting blocks 18 move into the unlocking hole 21, the rotating sleeve 19 rotates counterclockwise. At this time, the abutting sleeve 11 stretches multiple sets of reset springs 22. When the rotating sleeve 19 rotates, multiple sets of arc-shaped sliders 24 slide along the annular groove 25, so that multiple sets of limiting blocks 18 slide into the arc-shaped hole 20. The outer walls of multiple sets of I-shaped limiting blocks 18 abut against the outer wall of the rotating sleeve 19, thus completing the positioning of the screw 3.

[0040] However, when the camera needs to be disassembled, rotating the rotating sleeve 19 clockwise moves the multiple sets of limiting blocks 18 into the unlocking hole 21, releasing the limiting of the abutment sleeve 11. The multiple sets of reset springs 22 pull the abutment sleeve 11 to release the abutment of the multiple sets of abutment rods 10. The multiple sets of tension springs 15 pull the positioning block 9 out of the positioning groove 12, releasing the positioning of the connecting rod 5. Rotating the handle 13 drives the screw 3 to rotate through the connecting rod 5, so that the screw 3 and the fixing frame 2 are threaded together, so that the fixing plate 4 releases the clamping of the camera's outer wall, and the camera can be disassembled.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
