Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a battery replacement mechanism for a cruise unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft that are controlled by radio remote control and self-contained program control devices, or are operated completely or intermittently autonomously by onboard computers. Compared with manned aircraft, drones are often better suited for tasks that are too "dull, dirty or dangerous".

[0003] The battery life of drones is limited, the battery charging speed is relatively slow, and manual battery replacement is troublesome, which makes battery replacement in conventional drones more troublesome.

[0004] To this end, we proposed a cruise drone battery replacement mechanism to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that it is troublesome to replace batteries of conventional drones, and to propose a battery replacement mechanism for a cruise drone.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A cruise drone battery replacement mechanism comprises a first stepper motor, wherein the lower end of the first stepper motor of the first stepper motor is fixedly connected to a fixing plate, a frame is fixedly connected to the outer shell of the first stepper motor, a swivel seat is fixedly connected to the upper end of the rotor of the first stepper motor, the swivel seat is in movably contact with the frame, a camera is fixedly connected to the upper end of the swivel seat, a second stepper motor is fixedly connected to the inside of the swivel seat, a bearing frame is fixedly connected to the outside of the second stepper motor, a worm is fixedly connected to the front end of the rotor of the second stepper motor, a worm wheel is rotatably installed in the bearing frame, the worm wheel is meshed with the worm, a third stepper motor is fixedly connected to the middle part of the worm wheel, a threaded rod is fixedly connected to the rotor of the third stepper motor, a contact sensor is fixedly connected to the outer shell of the third stepper motor, a drone shell is parked on the frame, a battery is installed in the drone shell, the threaded rod is threadedly meshed with the battery, and the drone shell is threadedly meshed with the threaded rod to match. The second stepper motor is driven to rotate the worm, and the worm gear is driven to rotate through the worm, so that the worm gear drives the third stepper motor to rotate, and the third stepper motor drives the threaded rod to open, and the drone shell is parked on the rack. Similarly, the reverse drive is driven to clamp the threaded rod to the drone shell. When the threaded rod is clamped outside the drone shell, the threaded rod is driven to reverse at the same time, and the drone shell is pushed outward through the threaded rod, so that the drone shell is separated from the threaded rod, and the threaded rod continues to clamp inward to the battery. When the threaded rod clamps the battery, the contact sensors are contacted with each other, and when the contact sensor sends a contact signal The third stepper motor is then driven to rotate the threaded rod, which pulls the battery through the threaded rod. The threaded rod is used to press against the drone shell to separate the battery from the drone shell. The first stepper motor is then driven to rotate the swivel seat, and the camera is used to collect image data of the rack. After the battery is transferred to the cavity of the rack, the third stepper motor is then driven to reverse the threaded rod and push the battery into the rack. Similarly, another battery in the rack is taken out and pushed back into the drone shell. The first stepper motor is then driven to rotate the second stepper motor back, so as to facilitate automatic replacement of the battery in the drone shell.

[0008] Preferably, the frame includes a cross-shaped frame body, and the limit block and the battery box are fixedly connected to the cross-shaped frame body. After the drone shell is parked on the cross-shaped frame body, the limit block is used to guide the drone shell to slide toward the center of the cross-shaped frame body, and then the battery is replaced and pushed in, and the limit block is used to block the drone shell outside the drone shell to prevent the drone shell from sliding, so as to facilitate the installation of the battery in the drone shell.

[0009] Preferably, the frame further comprises a correction guardrail, wherein a pair of the correction guardrails are symmetrically provided and fixedly connected to the cross-shaped frame body. The correction guardrails are used to facilitate correction of the position of the drone housing.

[0010] Preferably, the frame further comprises a vibration motor, and the vibration motor is fixedly connected to the limit block. When the drone shell is parked on the cross-shaped frame, the vibration motor is driven to vibrate the limit block and the cross-shaped frame, and the cross-shaped frame acts on the correction guardrail to vibrate the correction guardrail, thereby reducing the resistance of the drone shell to be corrected.

[0011] Preferably, the bearing frame includes a fixed frame and a bearing seat, and the bearing seat is fixedly connected to the fixed frame. The bearing seat is used to conveniently guide the worm gear to rotate.

[0012] Preferably, the drone shell includes a shell, a spring buckle and a threaded seat, one end of the spring buckle is fixedly connected to the shell, and the threaded seat is fixedly connected to the spring buckle. The spring buckle is used to buckle the battery so that the battery is kept in the shell, and when the threaded rod squeezes the spring buckle, the spring buckle opens outward, thereby disengaging the drone shell from the battery.

[0013] Preferably, the drone housing further comprises a first guide block, which is fixedly connected to the outer end of the threaded seat. The first guide block facilitates guiding the threaded rod to be stuck in the threaded seat.

[0014] Preferably, the battery comprises a battery body and a threaded block, the battery body is provided with a buckle groove, and the threaded block is symmetrically fixedly connected to the outside of the battery body. When the threaded rod rotates, the threaded block is driven by the threaded rod, and the threaded block acts on the battery body, so that the threaded rod drives the battery to move.

[0015] Preferably, the battery further comprises a second guide block, which is symmetrically fixedly connected to the threaded block. The second guide block is used to guide the threaded rod to engage with the threaded block.

[0016] Preferably, the threaded rod comprises a threaded rod body and a guide cone, wherein the guide cone is fixedly connected to the outer end of the threaded rod body. When the threaded rod body pulls the battery, the guide cone enters the spring buckle, thereby causing the guide cone to press outward to open the spring buckle.

[0017] In summary, the technical effects and advantages of the present invention are as follows:

[0018] 1. Drive the second stepper motor to drive the worm to rotate, and the worm gear is driven by the worm to rotate, so that the worm gear drives the third stepper motor to rotate, and the third stepper motor drives the threaded rod to open, and the drone shell is parked on the rack. Similarly, the reverse drive is used to clamp the threaded rod to the drone shell. When the threaded rod is clamped outside the drone shell, the threaded rod is driven to reverse at the same time, and the drone shell is pushed outward by the threaded rod, so that the drone shell is separated from the threaded rod, and the threaded rod continues to clamp inward to the battery. When the threaded rod is clamped to the battery, the contact sensors are in contact with each other. When the contact sensor sends a contact signal After the signal is received, the third stepper motor is driven to drive the threaded rod to rotate, the battery is pulled through the threaded rod, and the threaded rod is used to press on the drone shell to make the battery detach from the drone shell, and the first stepper motor is driven to drive the rotating seat to rotate, and the camera is used to collect image data of the rack until the battery is transferred to the cavity of the rack, and then the third stepper motor is driven to drive the threaded rod to reverse, and the battery is pushed into the rack. Similarly, another battery in the rack is taken out and pushed back into the drone shell at the same time, and then the first stepper motor is driven to drive the second stepper motor to rotate back, so as to facilitate automatic replacement of the battery of the drone shell.

[0019] 2. After the drone shell is parked on the cross-shaped frame, use the limit block to guide the drone shell to slide to the center of the cross-shaped frame, then replace the battery. When pushing the battery in, use the limit block to block it outside the drone shell to prevent the drone shell from sliding, making it easier to install the battery in the drone shell.

[0020] 3. After the UAV shell is parked on the cross-shaped frame, the vibration motor is driven to vibrate the limit block and the cross-shaped frame, and the cross-shaped frame acts on the correction guardrail to vibrate, thereby reducing the resistance of the UAV shell to be corrected.
