Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV camera mounting fixture. Background Technology
[0002] In the field of drone applications, the camera, as the core sensing and shooting component, directly determines the image acquisition quality and data accuracy through its installation stability, and is widely applicable to scenarios such as aerial surveying and mapping, agricultural inspection, and security monitoring.
[0003] Existing mounting fixtures mostly adopt a "single-size adaptation" design, meaning that a rigid fixing structure is customized for the specific dimensions (such as diameter, length, and shell curvature) of a particular camera model. Examples include metal clamps locked with bolts and plastic holders with pre-set apertures. While this type of fixture can achieve stable mounting for the adapted model, when it's necessary to replace the camera with a different size (such as switching from a 30mm diameter high-definition aerial lens to a 50mm diameter infrared thermal imaging lens, or from a cylindrical shell camera to an irregularly shaped inspection lens), the original fixture must be completely disassembled and the corresponding fixing components replaced. This is not only cumbersome and time-consuming (each replacement takes an average of 15-20 minutes), but also requires the additional storage of multiple sets of different sizes of fixture parts, increasing equipment procurement and storage costs. Therefore, we propose a new drone camera mounting fixture. Utility Model Content
[0004] The purpose of this utility model is to provide a mounting fixture for drone cameras to solve the problem mentioned in the background art that the "single-size adaptation" design is not only cumbersome to operate and time-consuming.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone camera fixing fixture, comprising: a support ring;
[0006] It also includes: a fixed ring, which is fixedly connected inside the support ring. One end of the fixed ring is provided with a guide ring. The guide ring is slidably connected to a fastener inside. The surface of the guide ring is slidably connected to a rotating ring. The rotation of the rotating ring drives the fastener to move axially in a variable manner through the guide ring.
[0007] A limiting block is located on one side of the guide ring and is fixedly connected inside the rotating ring. A limit plate is fixedly connected to one side of the fixed ring. The rotation of the rotating ring drives the limiting block to rotate, and the limiting block is inserted into the limit plate to limit the rotation of the ring.
[0008] The guide ring has an arc-shaped groove on its surface that matches the fastener, and the fastener is inserted into the arc-shaped groove.
[0009] The fastener includes a guide rod that is slidably connected inside the arc-shaped groove. One end of the guide rod is fixedly connected to a connecting plate. A split plate is rotatably connected inside the connecting plate. One end of the split plate is rotatably connected to an abutment plate.
[0010] The top of the split plate is fixedly connected to one side of a first torsion spring, which is fixedly connected inside the connecting plate. A first slot adapted to the split plate is opened on one side of the connecting plate.
[0011] Among them, a second torsion spring is fixedly connected to one side of the top of the contact plate. The second torsion spring is fixedly connected to the inside of the split plate. A second slot adapted to the contact plate is opened on one side of the split plate.
[0012] The surface of the limiting plate has several limiting grooves arranged in a ring, and each limiting groove is adapted to the limiting block.
[0013] The guide ring has a rotating rod fixedly connected to its bottom, the fixed ring has a rotating groove adapted to the rotating rod at its top, and the fixed ring has a placement groove adapted to the fastener on the side of its top near the rotating groove.
[0014] One end of the limiting block is fixedly connected to a spring rod, which is fixedly connected inside the guide plate. The surface of the guide plate is provided with a vertical groove that matches the rotating ring.
[0015] This utility model has at least the following beneficial effects:
[0016] This utility model significantly expands the size adaptation range through the coordinated adjustment design of the guide ring and the fastener. The arc-shaped groove on the surface of the guide ring is precisely matched with the guide rod of the fastener. When the rotating ring rotates, it drives the guide ring to rotate synchronously. The inclined trajectory of the arc-shaped groove can drive the guide rod to slide along the groove, thereby realizing the "variant axial movement" of the fastener - it can shrink towards the center to clamp small-sized cameras, and it can also expand outward to adapt to large-sized devices. It can cover the fixing needs of multiple camera sizes without replacing any parts.
[0017] This utility model achieves flexible rotation of the fastener's split plate and contact plate through the first and second torsion springs. When facing irregularly shaped camera housings such as cylindrical or stepped housings, the split plate can adaptively adjust the tilt angle, and the contact plate can tightly fit the housing surface, avoiding loosening due to irregular shapes. Compared with traditional rigid tooling, the size adaptation range is expanded by more than 3 times, and the adaptability to irregularly shaped housings is significantly improved.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1
[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a drone camera fixing fixture, including: a support ring 1;
[0027] It also includes: a fixed ring 2, which is fixedly connected inside the support ring 1. A guide ring 3 is provided at one end of the fixed ring 2. A fastener 4 is slidably connected inside the guide ring 3. A rotating ring 5 is slidably connected to the surface of the guide ring 3. The rotating ring 5 rotates and drives the fastener 4 to move axially in a variable manner through the guide ring 3.
[0028] Limiting block 6 is located on one side of guide ring 3 and is fixedly connected to the inside of rotating ring 5. Limiting plate 7 is fixedly connected to one side of fixed ring 2. Rotation of rotating ring 5 drives limiting block 6 to rotate. Limiting block 6 is inserted into limiting plate 7 to limit the rotation of rotating ring 5.
[0029] Support ring 1 is the external basic frame of the entire tooling. Its main function is to provide a stable support structure for the tooling and to connect it to the drone fuselage (it can be fixed to the designated position of the drone by conventional methods such as bolts and clips). This ensures that the tooling as a whole does not shift or shake during the flight of the drone and provides a reliable installation benchmark for the subsequent camera fixing components.
[0030] The fixed ring 2, serving as the mounting carrier for the core functional components, is fixedly connected inside the support ring 1 (the connection method can be welding, integral molding, or high-strength bolt connection to ensure structural strength). Its main function is to integrate key components such as the guide ring 3 and the limiting plate 7, while providing a preliminary annular positioning space for the camera (the camera body can be placed inside the fixed ring 2 or in a mounting position adapted to the inner side of the fixed ring 2). The guide ring 3 is a key transition component connecting the fixed ring 2 and the fastener 4. Located at one end of the fixed ring 2, its core function is to provide a sliding guide path for the fastener 4 and, through cooperation with the rotating ring 5, convert the arc-shaped circular motion of the rotating ring 5 into the axial movement of the fastener 4, thereby clamping or loosening the camera. The guide ring 3 closes... The key structure is an arc-shaped groove, which is adapted to the guide rod 41 of the fastener 4. The guide rod 41 of the fastener 4 is inserted into the arc-shaped groove. When the guide ring 3 rotates with the rotating ring 5, the inclined trajectory of the arc-shaped groove will drive the guide rod 41 to slide along the arc-shaped groove, thereby realizing the "variant axial movement" of the fastener 4. At the same time, a rotating rod 8 is fixedly connected to the bottom of the guide ring 3. The rotating rod 8 is inserted into the rotating groove of the fixed ring 2, so that the guide ring 3 can rotate flexibly around the fixed ring 2, providing a motion basis for the subsequent adjustment of the position of the fastener 4. The rotating ring 5 is the adjustment and operation component of the tooling. It is slidably connected to the outside of the guide ring 3. Its main function is to realize circumferential rotation by manual drive and transmit the rotational force to the guide ring 3 and the limiting block 6.
[0031] For guide ring 3: When rotating ring 5 rotates, it drives guide ring 3 to rotate synchronously through sliding connection with guide ring 3 (such as friction drive or slot engagement), and then drives fastener 4 to move through arc-shaped sliding groove of guide ring 3;
[0032] For limiting block 6: The limiting block 6 is fixedly connected inside the rotating ring 5. When the rotating ring 5 rotates, it will directly drive the limiting block 6 to rotate synchronously, which prepares for the subsequent cooperation between the limiting block 6 and the limiting plate 7 to achieve the limiting.
[0033] The limiting block 6 is a key component for limiting the rotation angle of the rotating ring 5. It is located on one side of the guide ring 3 and is fixedly connected inside the rotating ring 5. Its main function is to insert into the limiting structure of the limiting plate 7 after the rotating ring 5 drives the guide ring 3 and the fastener 4 to adjust to the appropriate position (i.e., the camera is clamped and adjusted to the target shooting angle), thereby limiting the rotation of the rotating ring 5 and fixing the position of the fastener 4 and the camera angle. The limiting plate 7 is fixedly connected to one side of the fixed ring 2. Its main function is to cooperate with the limiting block 6 to provide a fixed limiting point for the rotation angle of the rotating ring 5, ensuring that the camera can be stably fixed at the preset shooting angle.
[0034] The surface of the guide ring 3 is provided with an arc-shaped groove that matches the fastener 4, and the fastener 4 is inserted into the arc-shaped groove.
[0035] Fastener 4 includes a guide rod 41 that is slidably connected inside the arc-shaped groove. One end of the guide rod 41 is fixedly connected to a connecting plate 42. A split plate 43 is rotatably connected inside the connecting plate 42. One end of the split plate 43 is rotatably connected to an abutment plate 44.
[0036] Fastener 4 is a component that directly contacts and clamps the camera. It is slidably connected inside the arc-shaped groove of guide ring 3. Its structural design has a certain degree of flexibility and can be adapted to drone cameras of different shapes and sizes. Specifically, it consists of guide rod 41, connecting plate 42, split plate 43, abutment plate 44, first torsion spring 45 and second torsion spring 46. The functions of each sub-component are as follows:
[0037] Guide rod 41: As a connecting component between fastener 4 and guide ring 3, it is inserted into the arc-shaped slide groove and can slide along the slide groove. One end of it is fixedly connected to the connecting plate 42 and is used to transmit the moving force brought by the arc-shaped slide groove, thereby driving the entire fastener 4 assembly to move.
[0038] Connecting plate 42: As the mounting base of the split plate 43, it has a first slot inside to accommodate the split plate 43, and at the same time, it is fixedly connected to the first torsion spring 45. Its function is to transmit the moving force of the guide rod 41 to the split plate 43 and provide rotation space for the split plate 43.
[0039] The split plate 43 is rotatably connected to the connecting plate 42 at one end and to the abutment plate 44 at the other end. It has a second slot inside (to accommodate the abutment plate 44). Its function is to adapt to the tilt angle of the camera surface by rotating itself, so as to avoid unstable clamping due to the irregular shape of the camera.
[0040] Contact plate 44: A component that directly contacts the camera surface. It is rotatably connected to the split plate 43 via the second torsion spring 46. Its function is to adhere to the camera surface through its own slight rotation during the clamping process, thereby increasing the contact area and improving the clamping stability, while avoiding damage to the camera housing due to rigid contact.
[0041] A first torsion spring 45 is fixedly connected to one side of the top of the tapping plate 43. The first torsion spring 45 is fixedly connected to the inside of the connecting plate 42. A first slot adapted to the tapping plate 43 is opened on one side of the connecting plate 42.
[0042] The first torsion spring 45 is fixedly connected between the inside of the connecting plate 42 and the top of the split plate 43. Its function is to provide a reset spring force for the split plate 43. When the fastener 4 loosens the camera, the split plate 43 can return to its initial position under the action of the first torsion spring 45, which is convenient for the next clamping operation.
[0043] A second torsion spring 46 is fixedly connected to one side of the top of the contact plate 44. The second torsion spring 46 is fixedly connected inside the split plate 43. A second slot adapted to the contact plate 44 is opened on one side of the split plate 43.
[0044] The second torsion spring 46 is fixedly connected between the inside of the tapping plate 43 and the top of the contact plate 44. Its function is to provide elastic buffer for the contact plate 44. When clamped, the contact plate 44 is tightly attached to the camera surface by the elastic force, and when released, the contact plate 44 is reset.
[0045] The bottom of the guide ring 3 is fixedly connected to a rotating rod 8, the top of the fixed ring 2 is provided with a rotating groove that matches the rotating rod 8, and the top of the fixed ring 2 is provided with a placement groove that matches the fastener 4 on the side near the rotating groove.
[0046] The rotating groove is adapted to the rotating rod 8 at the bottom of the guide ring 3, providing a circular motion trajectory for the rotation of the guide ring 3, ensuring that the guide ring 3 can rotate stably around the fixed ring 2. The placement groove is adapted to the fastener 4, and is used to store the fastener 4 when the tooling is not installed with a camera or the position of the fastener 4 is not adjusted, so as to prevent the fastener 4 from colliding with other parts due to shaking, and at the same time, it is convenient to quickly adjust the position of the fastener 4 later.
[0047] One end of the limiting block 6 is fixedly connected to a spring rod 9, which is fixedly connected inside the guide plate. The surface of the guide plate is provided with a vertical groove that matches the rotating ring 5.
[0048] One end of the limiting block 6 is fixedly connected to a spring rod 9, which is fixedly connected inside the guide plate (the guide plate surface has a vertical groove adapted to the rotating ring 5, which is used to provide vertical limit for the rotation of the rotating ring 5 and prevent the rotating ring 5 from axially shifting during rotation). The function of the spring rod 9 is to provide elastic extension force for the limiting block 6. When the rotating ring 5 rotates, the limiting block 6 moves with the rotating ring 5, and the spring rod 9 is compressed. When the rotating ring 5 rotates to the target position and the limiting block 6 is aligned with the limiting structure of the limiting plate 7, the spring rod 9 resets and pushes the limiting block 6 into the limiting structure to achieve the limiting. When it is necessary to release the limiting, it is only necessary to apply external force to overcome the elastic force of the spring rod 9 and pull the limiting block 6 away from the limiting structure.
[0049] Example 2
[0050] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the surface of the limiting plate 7 has several limiting grooves distributed in a ring, and the limiting grooves are all adapted to the limiting block 6.
[0051] The surface of the limiting plate 7 has several limiting grooves arranged in a ring, and all the limiting grooves are adapted to the limiting block 6. Its advantage is that it can provide multiple different limiting positions, so that the rotating ring 5 can adjust the limiting position according to the size of the camera, and can also be adapted to cameras of different sizes.
