Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a dual-handle starter for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aerial vehicles controlled by radio remote control equipment and their own program control devices. They have no cockpit but are equipped with autopilots, program control devices, information collection devices, and other equipment. Ground control station personnel track, locate, control, telemetry, and transmit data digitally using radar and other equipment. Compared to piloted aircraft, UAVs have greater maneuverability, are lighter, smaller, less expensive, and easier to use. UAVs, especially fixed-wing UAVs, typically use gasoline engines. The engine is mounted at the front of the fuselage, and a propeller and propeller fairing (or fairing) are installed at the engine's output end. To start the UAV engine, an engine starter is aligned with the propeller fairing, a certain amount of resistance is applied, and then the starter switch is turned on. The starter rotates the propeller fairing, thus starting the UAV engine.

[0003] See Patent 202222474645.1, filed by the applicant on September 19, 2022, which discloses a portable electric starter for drones, including a frame, a rechargeable battery, a motor, and a starter disc. The rechargeable battery is installed at the lower end of the frame, and the motor is installed at the upper end of the frame. A cylindrical body for gripping is installed outside the motor. The motor's shaft extends forward from the frame, and the starter disc is installed at the front end of the motor's shaft. When starting the drone engine, the user can directly grip the cylindrical body outside the motor, allowing the motor to apply a balanced counterforce to the starter disc at the front end of the shaft, reducing the likelihood of misalignment between the starter disc and the propeller fairing. However, this electric starter for drones also has the following problem: because the motor needs a sufficient diameter to rotate the drone's propeller fairing, the diameter of the cylindrical body outside the motor is relatively large. When the user grips the cylindrical body outside the motor, it is easy to experience problems such as difficulty in gripping, instability, and insufficient force. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dual-handle starter for unmanned aerial vehicles (UAVs) to address the shortcomings of the prior art. The left and right handles of this starter are easy for the user to grip, allowing the operator to hold the left and right handles with both hands respectively, ensuring a firm grip and effective force application. Furthermore, the motor is located between the left and right handles, and can apply a balanced thrust to the motor through the left and right handles, the front support plate, and the rear support plate. This, in turn, allows the motor to apply a balanced counterforce to the starter disc at the front end of the shaft, preventing misalignment between the starter disc and the propeller fairing.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dual-handle starter for unmanned aerial vehicles (UAVs), comprising a motor, a front support plate, a rear support plate, a left handle, a right handle, a battery mounting plate, a rechargeable battery, and a starter disk; the front end of the motor is fixedly connected to the middle of the front support plate, the rear end of the motor is fixedly connected to the middle of the rear support plate, the motor shaft extends forward from the front support plate, and the starter disk is mounted on the front end of the motor shaft; the starter disk comprises a metal sleeve and a rubber abutment head, the rubber abutment head is detachably installed inside the front end of the metal sleeve, and the front end of the rubber abutment head has an abutment notch for abutting against the UAV fairing; the left handle is connected between the left ends of the front and rear support plates, the right handle is connected between the right ends of the front and rear support plates, the battery mounting plate is connected between the lower middle ends of the front and rear support plates, the rechargeable battery is installed on the lower side of the battery mounting plate, and the rechargeable battery is electrically connected to the motor.

[0006] The beneficial effects of this utility model are as follows: Because a motor is fixedly connected between the middle of the front and rear support plates, the motor's shaft extends forward from the front support plate and is fitted with a starter disc, a left handle is connected between the left ends of the front and rear support plates, and a right handle is connected between the right ends of the front and rear support plates. Therefore, the left and right handles are easy for the operator to grip, allowing them to hold the left and right handles firmly and apply force effectively. Furthermore, the motor is located between the left and right handles, enabling a balanced thrust to be applied to the motor through the left and right handles, the front and rear support plates, and the motor to apply a balanced counterforce to the starter disc at the front end of the shaft. The starter disc and the propeller then rectify the flow. The design minimizes the risk of misalignment between the fairings. The starting disc of this invention includes a metal sleeve and a rubber abutment head. The front end of the rubber abutment head has an abutment notch for abutting against the drone fairing. When starting the drone engine, the abutment notch of the rubber abutment head generates significant friction with the propeller fairing, preventing slippage between them. Furthermore, since the rubber abutment head is detachably installed inside the front end of the metal sleeve, it is easy to remove the rubber abutment head from inside the front end of the metal sleeve and replace it with a matching rubber abutment head when starting different types of drones. This allows this invention to start different types of drones by replacing the rubber abutment head.

[0007] In the above technical solution, the front support plate is symmetrical from left to right, the rear support plate is symmetrical from left to right, the left handle and the right handle are symmetrical to each other, and the axis of rotation of the motor is located on the axis of symmetry between the left handle and the right handle. This symmetrical structure ensures that the thrust applied to the left and right handles is evenly distributed across the front and rear support plates, and then the front and rear support plates transmit the thrust in a symmetrical manner to the motor's axis of rotation.

[0008] In the above technical solution, the front end of the motor is provided with a front fixing cover, and two front connecting blocks are provided at each of the upper and lower ends of the front fixing cover. Two front connecting ears are provided at each of the upper and lower ends of the middle section of the front support plate. A front bolt is provided between the front connecting blocks and the front connecting ears, and the front connecting blocks and the front connecting ears are fixedly connected by the front bolt. The rear end of the motor is provided with a rear fixing cover, and two rear connecting blocks are provided at the upper end of the rear fixing cover. Two rear connecting ears are provided at the upper end of the middle section of the rear support plate. A rear bolt is provided between the rear connecting blocks and the rear connecting ears, and the rear connecting blocks and the rear connecting ears are fixedly connected by the rear bolt. This structure not only ensures the stable installation of the motor with the front and rear support plates, but also facilitates the installation and disassembly of the motor with the front and rear support plates.

[0009] In the above technical solution, the metal sleeve includes a sleeve body and a bushing. The bushing is integrally connected to the middle of the rear end of the sleeve body. The middle of the bushing has a shaft hole for connecting the motor shaft. A cavity is formed inside the front end of the sleeve body. The external shape of the rubber abutment matches the shape of the cavity of the sleeve body, and the rubber abutment is installed inside the cavity of the sleeve body. The metal sleeve can be securely connected to the motor shaft through the shaft hole of the bushing, and maintains stable rotation after being driven by the motor. The metal sleeve can securely install the rubber abutment through the cavity of the sleeve body. Because the external shape of the rubber abutment matches the shape of the cavity of the sleeve body, the metal sleeve can evenly apply the pushing force and rotational force to the rubber abutment.

[0010] In the above technical solution, the sleeve body is cylindrical, the cavity is cylindrical, and the rubber abutment head's abutment recess is conical or spindle-shaped. The cylindrical shape of the sleeve body allows it to maintain optimal dynamic balance and reduce vibration; the conical or spindle-shaped abutment recess of the rubber abutment head optimally matches the shape of the UAV propeller fairing.

[0011] In the above technical solution, a motor power cord is connected to the rear end of the motor, extending downwards and connecting to a female socket. The motor power cord and the female socket are mounted on the rear support plate. A battery power cord is connected to the rear side of the rechargeable battery, extending upwards and connecting to a male plug. The male plug is inserted into the female socket. When the rechargeable battery needs to be charged, the male plug is unplugged from the female socket and then inserted into the charger. After charging is complete, the male plug is inserted back into the female socket. Attached Figure Description

[0016] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, this utility model is a dual-handle starter for unmanned aerial vehicles (UAVs), including a motor 1, a front support plate 2, a rear support plate 3, a left handle 4, a right handle 5, a battery mounting plate 6, a rechargeable battery 7, and a starter disc 8; the front end of the motor 1 is fixedly connected to the middle of the front support plate 2, and the rear end of the motor 1 is fixedly connected to the middle of the rear support plate 3. The rotating shaft 11 of the motor 1 extends forward from the front support plate 2, and the starter disc 8 is mounted on the front end of the rotating shaft of the motor 1; the starter disc 8 includes a metal sleeve 81 and a rubber abutment head 82. The rubber abutment head 82 is detachably installed inside the front end of the metal sleeve 81. The front end of the rubber abutment head 82 is provided with an abutment recess 821 for abutting against the drone fairing 100. The left handle 4 is connected between the left ends of the front support plate 2 and the rear support plate 3, the right handle 5 is connected between the right ends of the front support plate 2 and the rear support plate 3, the battery mounting plate 6 is connected between the lower middle ends of the front support plate 2 and the rear support plate 3, and the rechargeable battery 7 is installed on the lower side of the battery mounting plate 6. The rechargeable battery 7 is electrically connected to the motor 1. Figure 4 As shown, when starting the drone engine, the operator first holds the left handle 4 and the right handle 5 with their left and right hands respectively, so that the motor pushes the starter plate at the front end of the shaft against the propeller fairing 100; then, the starter is activated, and the starter plate drives the propeller fairing 100 to rotate, thereby starting the drone engine.

[0018] In this invention, a motor 1 is fixedly connected between the middle of the front support plate 2 and the rear support plate 3. The rotating shaft of the motor 1 extends forward from the front support plate 2 and is fitted with a starter disc 8. A left handle 4 is connected between the left ends of the front support plate 2 and the rear support plate 3, and a right handle 5 is connected between the right ends of the front support plate 2 and the rear support plate 3. Therefore, the left handle 4 and the right handle 5 are easy for the operator to grip, allowing them to hold the left handle 4 and the right handle 5 with both hands, ensuring a firm grip and effective force application. Furthermore, the motor 1 is located between the left handle 4 and the right handle 5, enabling the motor 1 to be pushed with a balanced force through the left handle 4, the right handle 5, the front support plate 2, and the rear support plate 3. This, in turn, allows the motor 1 to exert a balanced counterforce on the starter disc 8 at the front end of the rotating shaft, reducing the likelihood of friction between the starter disc 8 and the propeller fairing. The problem of misalignment: In this invention, the starter disc 8 includes a metal sleeve 81 and a rubber abutment head 82. The front end of the rubber abutment head 82 is provided with an abutment recess 821 for abutting against the drone fairing 100. When starting the drone engine, the abutment recess 821 of the rubber abutment head 82 can generate a large frictional force between it and the propeller fairing, preventing the two from sliding against each other. Furthermore, since the rubber abutment head 82 is detachably installed inside the front end of the metal sleeve 81, when starting different types of drones, the rubber abutment head 82 can be easily removed from the front end of the metal sleeve 81 and replaced with a matching rubber abutment head 82. Thus, this invention can start different types of drones by replacing the rubber abutment head 82.

[0019] like Figures 1-4 As shown, the front support plate 2 is symmetrical from left to right, the rear support plate 3 is symmetrical from left to right, the left handle 4 and the right handle 5 are symmetrical to each other, and the axis of rotation of the motor 1 is located on the axis of symmetry between the left handle 4 and the right handle 5. This symmetrical structure ensures that the thrust applied to the left handle 4 and the right handle 5 is evenly distributed onto the front support plate 2 and the rear support plate 3, and then the thrust is centrally transmitted to the axis of rotation of the motor 1 via the front support plate 2 and the rear support plate 3.

[0020] like Figure 3As shown, the front end of the motor 1 is provided with a front fixing cover 12, and two front connecting blocks 13 are provided at each of the upper and lower ends of the front fixing cover 12. Two front connecting ears 21 are provided at each of the upper and lower ends of the middle section of the front support plate 2. A front bolt 91 is provided between the front connecting blocks 13 and the front connecting ears 21, and the front connecting blocks 13 and the front connecting ears 21 are fixedly connected by the front bolt 91. The rear end of the motor 1 is provided with a rear fixing cover 14, and two rear connecting blocks 15 are provided at the upper end of the rear fixing cover 14. Two rear connecting ears 31 are provided at the upper end of the middle section of the rear support plate 3. A rear bolt 92 is provided between the rear connecting blocks 15 and the rear connecting ears 31, and the rear connecting blocks 15 and the rear connecting ears 31 are fixedly connected by the rear bolt 92. This structure not only ensures the stable installation of the motor 1 with the front support plate 2 and the rear support plate 3, but also facilitates the installation and disassembly of the motor 1 with the front support plate 2 and the rear support plate 3.

[0021] like Figure 3 As shown, the metal sleeve 81 includes a sleeve body 811 and a bushing 812. The bushing 812 is integrally connected to the middle of the rear end of the sleeve body 811. The middle of the bushing 812 is provided with a shaft hole for connecting the rotating shaft of the motor 1. A cavity 813 is formed inside the front end of the sleeve body 811. The external shape of the rubber abutment 82 matches the shape of the cavity 813 of the sleeve body 811, and the rubber abutment 82 is installed inside the cavity 813 of the sleeve body 811. The metal sleeve 81 can be securely connected to the rotating shaft of the motor 1 through the shaft hole of the bushing 812, and after being driven by the motor 1, it maintains stable rotation. The metal sleeve 81 can securely mount the rubber abutment head 82 through the cavity 813 of the sleeve body 811. Since the external shape of the rubber abutment head 82 matches the shape of the cavity 813 of the sleeve body 811, the metal sleeve 81 can evenly apply the pushing force and rotational force to the rubber abutment head 82.

[0022] like Figure 3 As shown, the sleeve body 811 is cylindrical in shape, the cavity is cylindrical in shape, and the abutment recess 821 of the rubber abutment head 82 is conical or spindle-shaped. The cylindrical shape of the sleeve body 811 allows it to maintain optimal dynamic balance and reduce vibration; the conical or spindle-shaped abutment recess 821 of the rubber abutment head 82 optimally matches the shape of the UAV propeller fairing.

[0023] like Figure 2As shown, a motor power cord 16 is connected to the rear end of the motor 1. The motor power cord 16 extends downward and connects to a female socket 161. The motor power cord 16 and the female socket 161 are mounted on the rear support plate 3. A battery power cord 71 is connected to the rear side of the rechargeable battery 7. The battery power cord 71 extends upward and connects to a male plug 711, which is inserted into the female socket 161. When the rechargeable battery 7 needs to be charged, the male plug 711 is unplugged from the female socket 161 and then plugged into the charger. After charging is complete, the male plug 711 is plugged back into the female socket 161.

[0024] The above description is merely a preferred embodiment of this utility model.
