DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figures 1 to 6As shown, an embodiment of the present invention provides a quick docking and separation mechanism suitable for an ejection device, including a pair of relatively arranged main frame structures, on which a guide cone pin 8 and a guide seat 3 are provided, and a mover 10 is provided between the relatively arranged main frames, and the mover 10 is provided with a pin hole that cooperates with the guide cone pin 8, and the mover 10 is connected to a drone bracket 14, on which a slide rail 13 is provided, and on which a sliding shaft 4 is cooperated, and the main frame slides relatively along the slide rail 13 through the guide seat 3 and the sliding shaft 4.

[0030] In this embodiment, a pair of relatively arranged main frame structures are welded and spliced ​​by a cone pin mounting seat 1, a square tube 2, a guide seat 3 and a main shaft 7. A pair of main frames and a mover 10 constitute a docking and separation mechanism on both sides, and the docking and separation mechanisms on both sides are a left docking and separation mechanism 11 and a right docking and separation mechanism 12 respectively. A set of docking and separation mechanisms are installed on the left and right sides of the drone bracket 14. By rotating the manual wheel 9 clockwise, the mechanism can be quickly advanced along the slide rail 13, driving the guide cone pin 8 to insert into the docking hole of the mover 10, and the drone bracket 14 can be quickly and accurately docked with the mover 10. Through the docking of the left and right sides, it can adapt to the road surface with slopes on the left and right sides, effectively avoiding the abnormal separation of the drone bracket 14 and the mover 10, and ensuring the connection reliability. No matter which side is higher, it will not cause the drone bracket 14 and the mover 10 to separate. There will always be a guide cone pin 8 on one side inserted in the pin hole of the mover 10, which can well adapt to the road surface with slopes.

[0031] In this embodiment, the main frame structure is provided with a guide cone pin 8 and a guide seat 3. The guide cone pin 8 is used to cooperate with the pin hole on the mover 10, thereby limiting the mover 10. The guide seat 3 is slidably matched with the slide rail 13 of the drone bracket 14, wherein each main frame structure is provided with a pair of guide seats 3. The drone bracket 14 is connected to the drone. The function of the guide seat 3 is to guide the main frame structure, ensure that the main frame structure slides along the slide rail 13, and the guide seat 3 cooperates with the slide rail 13 to ensure the accuracy of the sliding of the main frame structure, thereby ensuring that the guide cone pin 8 is accurately inserted into the pin hole of the mover 10, thereby ensuring the accuracy of the cooperation between the guide cone pin 8 and the pin hole on the mover 10, wherein the tip of the guide cone pin 8 is set to a cone shape, which further ensures that the guide cone pin 8 is reliably inserted into the pin hole of the mover 10, and is arranged in a state where the insertion fails due to an error, giving the guide cone pin 8 a certain error space in the pin control of the mover 10.

[0032] In this embodiment, a mover 10 is provided between the relatively arranged main frames, and a pin hole is provided on the mover 10 to cooperate with the guide cone pin 8. The mover 10 is connected to the UAV bracket 14, and the UAV bracket 14 is provided with a slide rail 13, which plays a guiding role. The slide rail 13 is matched with a sliding shaft 4, and the main frame slides relatively along the slide rail 13 through the guide seat 3 and the sliding shaft 4. The guide seat 3 and the slide rail 13 are both provided with a sliding shaft 4. The setting of the sliding shaft 4 converts the friction between the guide seat 3 and the slide rail 13 into rolling friction, reduces the friction resistance, and ensures rapid docking and separation, wherein the mover 10 is used to be connected to the UAV bracket 14, and the UAV bracket 14 is used to support and connect the UAV.

[0033] In this embodiment, the main shaft 7 is connected to the manual wheel 9 through a screw rod, and the manual wheel 9 is installed on the UAV bracket 14 through a sleeve 5. The manual wheel 9 is connected to the main shaft 7 by a threaded pair. When the manual wheel 9 is rotated counterclockwise, the main frame structure quickly retreats along the slide rail 13, driving the guide cone pin 8 to disengage from the docking hole of the mover 10, thereby realizing the rapid separation of the UAV bracket 14 and the mover 10. The manual wheel 9 drives the screw rod to rotate, the screw rod drives the main shaft 7 to move, the main shaft 7 drives the herringbone square tube 2 to move, and the herringbone square tube 2 drives the cone pin mounting seat 1 to move. The function of the handwheel is to realize the rotation to provide the power for the movement of the main frame, wherein the handwheel and the main shaft 7 are matched through threads to realize more reliable and accurate control of the movement of the main frame structure. Through the guidance of the slide rail 13 and the guide seat 3, the rotation of the handwheel is converted into a linear movement of the main frame structure, thereby ensuring that the guide cone pin 8 is reliably inserted into the pin hole of the mover 10.

[0034] In this embodiment, the square tubes 2 are spliced ​​into a herringbone structure, and the main shaft 7 is located at the central axis of the main frame structure. The square tubes 2 are spliced ​​into a herringbone structure to play a supporting role and form a part of the main frame structure. A screw is provided on the handwheel, and a threaded hole is provided inside the main shaft 7. The screw and the threaded hole are matched through threads. The main shaft 7 is rotated to drive the screw to rotate, thereby driving the main shaft 7 to move.

[0035] In this embodiment, Figure 1As shown, the taper pin mounting seat 1, the square tube 2, the guide seat 3 and the main shaft 7 are assembled into a main frame by welding, and the main frame is symmetrical with respect to the center plane of the main shaft 7; the sliding shaft 4 is installed on the slide rail 13 of the UAV bracket 14 through the locking nut 6, so as to reduce the friction resistance of the docking and separation mechanism when moving on the slide rail 13; the guide seat 3 and the slide rail 13 of the UAV bracket 14 are slidably matched, so as to constrain and guide the motion trajectory of the mechanism and realize precise positioning; the guide taper pin 8 is stably installed on the taper pin mounting seat 1, and the guide taper pin 8 is designed at the front, so as to effectively improve the docking accuracy and reduce the difficulty of docking and separation; the manual wheel 9 is installed on the UAV bracket 14 through the shaft sleeve 5, and the manual wheel 9 and the main shaft 7 are connected with a threaded pair, and the forward and backward movement of the mechanism are realized by relative rotation.

[0036] In this embodiment, Figure 3 As shown, a set of docking and separation mechanisms are installed on the left and right sides of the UAV bracket 14. By turning the manual wheel 9 clockwise, the mechanism can be quickly advanced along the slide rail 13, driving the guide cone pin 8 to insert into the docking hole of the mover 10, thereby realizing the rapid and accurate docking of the UAV bracket 14 and the mover 10. The docking on the left and right sides can adapt to the road surface with slopes on the left and right sides, effectively avoiding the abnormal separation of the UAV bracket 14 and the mover 10, and ensuring the reliability of the connection.

[0037] In this embodiment, Figure 5 As shown, by rotating the manual wheel 9 counterclockwise, the mechanism can be quickly retreated along the slide rail 13, driving the guide cone pin 8 to disengage from the docking hole of the mover 10, thereby achieving rapid separation of the UAV bracket 14 and the mover 10.

[0038] The quick docking and separation mechanism of this embodiment is light in weight, compact in structure, and high in rigidity. It provides a new docking and separation mechanism to meet the needs of rapid and continuous catapult takeoff, and can be applied to the docking and separation of various types of UAV brackets 14 and movers 10.

[0039] In another embodiment, three sets of manual wheels 9 can be used instead of one set of manual wheels 9 to drive a single guide cone pin 8 forward or backward respectively, so as to achieve precise docking between the UAV bracket 14 and the mover 10; a guide cone pin 8 with a thread on the front can be used, and after the guide cone pin 8 enters the mover 10, it is locked by a nut to replace the docking and separation mechanism on one side.

[0040] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0041] A set of docking and separation mechanisms are installed on the left and right sides of the drone bracket 14. By turning the manual wheel 9 clockwise, the mechanism can be quickly advanced along the slide rail 13, driving the guide cone pin 8 to insert into the docking hole of the mover 10, so that the drone bracket 14 and the mover 10 can be quickly and accurately docked. The docking on the left and right sides can adapt to the road surface with slopes on the left and right sides, effectively avoiding abnormal separation of the drone bracket 14 and the mover 10, and ensuring the reliability of the connection.

For those skilled in the art, the present invention may have various modifications and variations.
