Description

Technical Field

[0001] This utility model relates to the field of servo gimbal technology, and in particular to a servo gimbal for toy drones. Background Technology

[0002] A servo gimbal is a device used for connection and fixation. It can connect and fix connected devices such as cameras, radar equipment, and sensors to the connected device, enabling it to move in one or more directions.

[0003] A search revealed Chinese patent CN207773516U, which discloses a servo-driven folding gimbal for connecting a device to another device. The folding gimbal includes a fixing component, a servo motor, a linkage mechanism, and a receiving component. The fixing component is connected to the device to be connected. The servo motor provides power to the folding gimbal. The linkage mechanism converts the linear motion output by the servo motor into curvilinear motion to achieve folding. The receiving component connects the linkage mechanism and the device to be connected. This invention achieves the folding effect of the gimbal through a linkage mechanism and an elastic series mechanism. The folded gimbal reduces its space occupation, making it easier to store and carry. Furthermore, in the working state, the linkage mechanism maintains a certain distance between the device to be connected and the device to be connected, thus solving the problem of physical interference between the connected device and the device to be connected, such as the problem of a drone entering the camera's field of view.

[0004] In this patent, the camera lens is directly exposed to the external environment without any protection. Therefore, when the drone is flying, dust easily adheres to the camera lens, thereby reducing the clarity of the image. Manually cleaning the lens after landing the drone is quite time-consuming.

[0005] Therefore, we made improvements and proposed a servo gimbal for toy drones. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that camera lenses are prone to dust accumulation, thereby reducing the clarity of the images, and to propose a servo gimbal for toy drones.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A servo gimbal for a toy drone includes a U-shaped frame with an open bottom. The lower half of the U-shaped frame houses the gimbal body, and a camera is detachably connected to the bottom of the gimbal body. A horizontal shell is provided on one side of the U-shaped frame, with openings on both the side closest to the U-shaped frame and the bottom side. A connecting part is provided between the horizontal shell and the U-shaped frame. A storage shell is fixedly connected to the side of the horizontal shell away from the U-shaped frame, and the horizontal shell communicates with the storage shell. A scraper is provided inside the storage shell, with one side of the scraper fitting against the side of the horizontal shell away from the U-shaped frame. A drive unit is provided inside the storage shell.

[0009] As a preferred technical solution of this application, the driving unit includes a motor fixedly connected to the top of the storage shell, a lead screw being driven to the output end of the motor, the bottom end of the lead screw being rotatably connected to the inner top wall of the storage shell, a guide rod being vertically rotatably connected inside the storage shell, and side plates being fixedly connected to opposite sides of the scraper, one side plate being threadedly connected to the lead screw, and the other side plate being slidably connected to the guide rod.

[0010] As a preferred technical solution of this application, the connecting part includes two connecting plates that are fixedly connected to opposite sides of the transverse shell. The connecting plates are L-shaped, and the inner sidewall of the connecting plate is in contact with the outer wall of the shaped frame. The connecting plates and the shaped frame are fixedly connected by bolts.

[0011] As a preferred technical solution of this application, a waist-shaped hole is provided on one side of the connecting plate, the bolt passes through the waist-shaped hole, and a threaded groove is provided on the side wall of the shaped frame corresponding to the waist-shaped hole, and the bolt is partially threaded into the threaded groove.

[0012] As a preferred technical solution of this application, the sidewall of the C-shaped frame is provided with long grooves on both the upper and lower sides of the connecting plate. The long grooves penetrate the C-shaped frame from left to right. The top and bottom of the connecting plate are fixedly connected with L-shaped limiting plates, and the limiting plates are partially slidably inserted into the corresponding long grooves.

[0013] Compared with the prior art, this utility model provides a servo gimbal for toy drones, which has the following advantages:

[0014] 1. This servo gimbal for toy drones, through the cooperation of a drive unit, scraper, horizontal shell, and storage shell, allows the gimbal to control the camera to rotate into the horizontal shell when the camera lens needs to be cleaned. Then, the drive unit drives the scraper to move vertically across the camera lens surface, removing dust from the camera lens. After that, the gimbal controls the camera to leave the horizontal shell to continue shooting. This solves the problem in the existing technology that when the camera lens is flying, dust easily adheres to it, thus reducing the clarity of the shot, and that manually cleaning it after landing the drone is time-consuming.

[0015] 2. The servo gimbal for toy drones, through the combination of the connecting plate, bolts, oblong holes and threaded grooves, allows the gimbal body to be used with cameras of different lengths. By adjusting the position of the connecting plate, the distance between the horizontal shell and the U-shaped frame can be adjusted, ensuring that the camera lens and the scraper are coplanar after the camera enters the horizontal shell. This makes the device suitable for cameras of different lengths and improves its applicability.

[0016] 3. This servo gimbal for toy drones can be separated from the frame by unscrewing the bolts through the use of bolts and connecting plates, thus facilitating the storage of the device. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0025] Reference Figure 1-5A servo gimbal for a toy drone includes a U-shaped frame 1 with an open bottom. A gimbal body 2 is installed in the lower half of the U-shaped frame 1. A camera 3 is detachably connected to the bottom of the gimbal body 2. A horizontal shell 4 is provided on one side of the U-shaped frame 1. The side of the horizontal shell 4 closest to the U-shaped frame 1 and the bottom side are open. A connecting part 5 is provided between the horizontal shell 4 and the U-shaped frame 1. A storage shell 6 is fixedly connected to the side of the horizontal shell 4 away from the U-shaped frame 1, and the horizontal shell 4 communicates with the storage shell 6. A scraper 7 is provided inside the storage shell 6. One side of the scraper 7 is attached to the side of the horizontal shell 4 away from the U-shaped frame 1. A drive part 8 is provided inside the storage shell 6.

[0026] The U-shaped frame 1 is fixed to the bottom of the drone, and the gimbal body 2 can drive the camera 3 to rotate. This is existing technology and will not be described in detail here.

[0027] The lens of camera 3 is located at the bottom of camera 3. When it is necessary to clean the lens of camera 3, the gimbal body 2 controls the rotation of camera 3 so that camera 3 enters the horizontal shell 4 and camera 3 is in a horizontal state. The lens of camera 3 and the side of horizontal shell 4 away from the bracket 1 are coplanar.

[0028] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, the drive unit 8 further includes a motor 81 fixedly connected to the top of the storage shell 6. The output end of the motor 81 is connected to a lead screw 82. The bottom end of the lead screw 82 is rotatably connected to the inner top wall of the storage shell 6. A guide rod 83 is vertically rotatably connected inside the storage shell 6. Side plates 84 are fixedly connected to both sides of the scraper 7. One side plate 84 is threadedly connected to the lead screw 82, and the other side plate 84 is slidably connected to the guide rod 83.

[0029] In the initial state, the scraper 7 is located above the opening on the right side of the transverse shell 4. When the motor 81 is working, it drives the lead screw 82 to rotate. The rotation of the lead screw 82 drives the side plate 84 and the scraper 7 to move downward. During the downward movement of the scraper 7, it contacts the lens of the camera 3 and scrapes off the dust on the lens of the camera 3, thereby cleaning the lens of the camera 3.

[0030] like Figure 1 As shown, in a preferred embodiment, based on the above method, the connecting part 5 further includes two connecting plates 51 that are fixedly connected to opposite sides of the transverse shell 4. The connecting plates 51 are L-shaped, and the inner sidewall of the connecting plate 51 is in contact with the outer wall of the shaped frame 1. The connecting plate 51 and the shaped frame 1 are fixedly connected by bolts 52.

[0031] When using this device, the connecting plate 51 can be separated from the bracket 1 by unscrewing the bolt 52, which makes it easier to store the device.

[0032] like Figure 1-3As shown, in a preferred embodiment, based on the above method, a waist-shaped hole 53 is further provided on one side of the connecting plate 51, and the bolt 52 passes through the waist-shaped hole 53. A threaded groove 54 is provided on the side wall of the C-shaped frame 1 corresponding to the waist-shaped hole 53. The bolt 52 is partially threaded into the threaded groove 54, and the head of the bolt 52 tightly presses against the side wall of the connecting plate 51, thereby fixing the connecting plate 51 and the C-shaped frame 1 together.

[0033] The prerequisite for this device to clean the lens of camera 3 is that camera 3 is inserted into the horizontal shell 4 and is horizontal, and the lens of camera 3 is coplanar with the scraper 7. Therefore, when cameras 3 of different lengths are installed on the gimbal body 2, the distance between the horizontal shell 4 and the bracket 1 can be adjusted by adjusting the position of the connecting plate 51 to ensure that the lens of camera 3 is coplanar with the scraper 7 after camera 3 is inserted into the horizontal shell 4. This makes the device applicable to cameras 3 of different lengths and improves the applicability of the device.

[0034] like Figure 1-3 As shown, in a preferred embodiment, based on the above method, the side wall of the C-shaped frame 1 is provided with long grooves 9 on both the upper and lower sides of the connecting plate 51. The long grooves 9 penetrate the C-shaped frame 1 from left to right. The top and bottom of the connecting plate 51 are fixedly connected with L-shaped limiting plates 10, and the limiting plates 10 are partially slidably inserted into the corresponding long grooves 9.

[0035] The limiting plate 10 limits the connecting plate 51 to prevent the pressure between the horizontal shell 4 and the storage shell 6 from causing the connecting plate 51 to tilt.

[0036] Specifically, the servo gimbal, originally intended for toy drones, operates as follows:

[0037] First, insert the limiting plate 10 into the corresponding long slot 9, slide the connecting plate 51 to the appropriate position (the lens of the camera 3 and the scraper 7 are on the same side when the camera 3 is horizontal), and then screw the bolt 52 through the waist-shaped hole 53 into the threaded groove 54, thereby assembling the connecting plate 51 and the frame 1 together.

[0038] When it is necessary to clean the lens of camera 3, the gimbal body 2 controls the camera 3 to rotate, so that the camera 3 enters the horizontal housing 4 and the camera 3 is in a horizontal position. When the motor 81 works, it drives the lead screw 82 to rotate. The rotation of the lead screw 82 drives the side plate 84 and the scraper 7 to move downward. During the movement from top to bottom, the scraper 7 contacts the lens of camera 3 and scrapes off the dust on the lens of camera 3, thereby cleaning the lens of camera 3. Then, the gimbal body 2 controls the camera 3 to leave the horizontal housing 4 to continue shooting. The motor 81 reverses and sends the scraper 7 back to the initial position.

[0039] After the device is used, the connecting plate 51 can be separated from the bracket 1 by unscrewing the bolt 52, which makes it easy to store the device.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
