Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary supporting devices for unmanned aerial vehicles, and in particular relates to a vehicle-mounted unmanned aerial vehicle ejection device. Background Art

[0002] In recent years, with the development of science and technology, drones have played an increasingly important role in various fields, and various types of drones have been developed. Fixed-wing drones require a higher speed when taking off, but due to their limited propulsion capabilities, they cannot obtain an effective initial take-off speed. Therefore, the use of catapults has become the main way for drones to take off.

[0003] The UAV catapult takeoff process is summarized as follows: (1) Before ejection, first connect the ejection bracket to the ejection pulley and place the UAV on the ejection bracket; then start the power system. Since the power system generates a strong thrust, the UAV tends to move forward. At this time, the UAV must be locked to prevent it from flying off due to the thrust. (2) After the ejection pulley is released under the power traction of the ejection device, the UAV accelerates along the ejection direction on the ejection bracket. At the end of the ejection track, the UAV obtains a certain takeoff speed and completes takeoff.

[0004] Therefore, the ejection bracket should have the following functions: (1) When the UAV power system is started, the ejection bracket can lock the UAV to prevent it from flying off under the thrust of the power system; (2) During ejection, the locking mechanism can be opened in a timely and accurate manner to ensure that the UAV can smoothly detach from the ejection bracket and take off successfully. However, the locking structure between the existing ejection device and the UAV is complex and difficult to operate. Generally, a locking part that is locked with the ejection device is set in the middle of the bottom of the UAV fuselage, which is a single-point fixing method. The opening and closing lock design of the existing single-point locking mechanism UAV ejection device is complex and difficult to operate. It has a large torque, unbalanced force, and a safety system. The number is low, which cannot well ensure the balance of the drone when taking off. On the other hand, the ejection device stops and locks the front of the drone. The front pressure on the locking structure is too large, which is easy to cause damage to the locking structure and is not conducive to unlocking the locking structure. In addition, some existing vehicle-mounted ejection racks are fixed on the roof, which takes up a lot of space and requires the drone to be moved to the roof for installation and ready for launch. The operation is extremely inconvenient and affects the timing. In addition, the ejection energy storage of the existing ejection racks all uses rubber bands or compressed air. The disadvantage is that compressed air needs to solve the compressed air source, and the supporting equipment such as gas tanks and air compressors bring transportation and installation operation time problems, and are prone to failure. The rubber band energy storage method will cause rubber fatigue and aging, and the rubber energy storage will be reduced due to the influence of climate; in addition, the rubber energy storage method using rubber bands will cause rubber fatigue and aging, and the rubber energy storage will be reduced due to the influence of climate.

When the sliding base moves backward and compresses the second spring to the ejection release device, the sliding base is fixed and locked by the ejection release device 40, so that the sliding ejection bracket 30 and the UAV thereon are in a ready-to-launch state. When launching is required, the ejection release device is controlled to unlock the sliding base, so that it accelerates forward under the elastic force of the second spring to complete the launching. In actual application, in order to ensure that sufficient elastic potential energy is provided, the axial length of the second spring when it is not compressed is much greater than the axial length of the first spring when it is not compressed.

[0052] Specifically, the lower end of the second stop portion 34 is movably fixed to the bracket 32 ​​by a screw 37, and the lower end of the second stop portion 34 is provided with a long slot hole 341 for the screw 37 to pass through and the length of which is much larger than the outer diameter of the screw, so that the position of the second stop portion 34 can be adjusted forward and backward within the range of the long slot hole 341, so as to adjust the distance between the two stop portions to adapt to the two buckles on the drone, and avoid the influence of processing errors and the resulting position difference that makes it impossible to fix the drone; the upper end protrusion of the second stop portion 34 is provided with a U-shaped bayonet 342 higher than the bracket 32, and the upper end opening of the U-shaped bayonet 342 is provided with a pin 343 for blocking, which is used for the buckle on the rear end of the drone to snap into and achieve stopping.

[0053] Specifically, the first stop portion 33 includes a vertical portion 331 rotatably arranged on the bracket 32, a locking portion 332 arranged at the upper end of the vertical portion 331 and extending to the inner side of the bracket 32, and a force-bearing portion 333 arranged at the lower end of the vertical portion 331 and extending outward from the bracket 32, that is, the first stop portion 33 is Z-shaped as a whole, and the locking portion 332 is located just in front of the pin 343, and is used to engage with the buckle on the front end of the drone, and the locking portion is used to achieve the purpose of side engagement, and one end of the fork 35 is placed above the force-bearing portion 333 and abuts against the force-bearing portion 333, so that the purpose of pressing down the first stop portion is achieved when the fork rotates backward counterclockwise.

[0054] Specifically, the shape of the fork 35 is a right angle or a "7" shape. The corner of the fork 35 is rotatably arranged on the outer side of the upper end of the bracket 32 ​​through a circular shaft and a bearing. The upper right-angled side of the fork 35 extends horizontally to the upper end of the force-bearing portion 333, and the lower right-angled side of the fork 35 extends downward to the outer side of the frame-shaped ejection frame 20. A first return spring 38 is also provided between the lower end of the fork 35 and the bracket 32 ​​to achieve the purpose of forward rotation and reset after the fork rotates backward. A first pulley 39 is provided at the lower end of the fork 35. The outer sides of the rear ends of the two brackets 32 are provided with handles 321 extending outwardly for manually controlling their backward movement. Moving the sliding base is simple and labor-saving; the right-angled side at the lower end of the fork is a two-section design with adjustable length, and the length of the two sections is adjusted by means of holes and screws, so that the length of the fork can be adjusted according to actual conditions and cooperated with the external structure or components that control its backward rotation to achieve the purpose of pressing down; a limit rod 26 is also provided at the lower end of the outer side of the two brackets 32, and a gap exists between the limit rod 26 and the bracket 32 ​​to form a limit groove, and the lower end of the pressure rod 35 passes downward through the gap between the limit rod 26 and the bracket 32, so that the pressure rod can only rotate within the range of the limit groove, thereby avoiding excessive rotation of the pressure rod, which may cause damage to it and the force-bearing part.

[0055] Specifically, both outer sides of the front end of the frame-shaped ejection frame 20 are provided with an unlocking slide bridge 27 for stopping the fork 35 and causing it to rotate backward.

The first pulley 39 is lower than the upper end surface of the unlocking slide bridge 27. In this way, when the sliding ejection bracket moves forward under the elastic force of the second spring and slides to the unlocking slide bridge position, the lower end of the fork is stopped by the unlocking slide bridge and then rotates backward, so that the upper end of the fork presses down the force-bearing part 333 to complete the launch and unlocking action of the drone. After the fork rotates backward, the first pulley at the lower end of the fork can slide into the upper end of the unlocking slide bridge along the arc surface, so that the sliding ejection bracket can continue to slide forward until it hits the first spring, thereby avoiding the sliding ejection bracket being stopped by the unlocking slide bridge and being ejected directly to a stationary state at high speed, thereby reducing the collision force. The unlocking slide bridge is fixed by a hole groove and a screw, so that the position of the unlocking slide bridge can be adjusted back and forth within the range of the hole groove.

The two reverse buckles 104 are respectively engaged and fixed with the first stopper and the second stopper on the vehicle-mounted UAV ejection device, and the two buckles on the left and right wings are respectively matched and fixed with the two stoppers on the two brackets (such as Fig. 27 As shown); in the above structure, two buckles facing opposite directions are respectively arranged at the bottom of the left and right wings on both sides of the fuselage, and the buckles are used to cooperate and fix with the corresponding snap-fit ​​parts on the ejection device, so that the front and rear ends of the UAV and the ejection device are locked. The assembly method of the buckles has the characteristics of simple structure and easy assembly and disassembly, and the buckle structures on the two wings are arranged symmetrically on the left and right. A double fixing mode is formed by the buckle structures on the two wings. First, the locking combination force between the UAV and the ejection device is strengthened, second, it is easy to observe with the naked eye, which is convenient for the alignment assembly between the UAV and the ejection device, and third, the force balance of the UAV can be guaranteed when taking off.

[0063] Specifically, the outer sides of the four buckles 104 are each provided with a slot 1041 that opens outward and is horizontally arranged, so that one of the slots 1041 on the two buckles 104 on the same wing faces the head direction of the fuselage, and the other faces the tail direction of the fuselage. The fixing method of the slots is convenient for fixing and assembly.

[0064] Specifically, the buckle 104 is an isosceles trapezoidal structure with a small lower end and a large upper end, so that the upper end of the card slot is longer than the lower end. The upper end of the card slot plays a certain positioning role, making it convenient for the card slot to be inserted into the corresponding engaging portion on the ejection device.

[0065] Specifically, the middle protrusion on the upper end of the buckle 104 is provided with a fixing plate 1042 that is inserted into the left wing or the right wing, and is fixed to the wing through the fixing plate; the fixing plate 1042 is penetrated by at least two through holes 1043 arranged in sequence up and down, and the fixing plate is fixed to the wing after two screws (not shown in the figure) pass through the two through holes respectively, and the firmness between the buckle and the wing is ensured by double screw fixing.

[0066] In this embodiment, the left wing 1021 and the right wing 1022 are respectively arranged on the left and right sides of the rear end of the fuselage 101, and canards 107 are provided on the left and right sides of the front end of the fuselage. The canards are used to place the horizontal stability surface of the drone in front of the wings, so that vortices are generated above the wings, thereby increasing the stall angle of attack.

[0067] In this embodiment, a camera 105 is provided at the bottom of the front end of the fuselage 101 , and a pitot tube 106 extending forward is also provided at the front end of the fuselage 101 .

[0068] In this embodiment, a linkage aileron 108 is provided on the rear side of the left wing 1021 and the right wing 1022 .

[0069] In other embodiments of the present invention, a power device (such as a motor) connected to the thrust propeller transmission, a control system respectively connected to the power device, a camera, a linked aileron and a pitot tube, and an energy storage device (such as a battery or a lithium battery, etc.) for power supply are provided in the fuselage.

[0070] The state of the drone being fixed in the sliding ejection bracket and in a state ready for launch is as follows: Fig.26 shown.
