[0051] Light and small flying equipment has been widely used in surveying and mapping, exploration, plant protection, reconnaissance, firefighting, security, power inspection, aerial photography for film and television, and other fields, but its application in various complex environments is subject to take-off and landing conditions.

[0052] Flight equipment can take off using two methods: runway taxiing and accelerator-assisted takeoff. Accelerator-assisted takeoff is less susceptible to site constraints and is suitable for aircraft taking off on short runways or in confined spaces. During assisted takeoff, the accelerator and aircraft undergo a process of connection and separation, necessitating an effective accelerator release mechanism to ensure safe, efficient, reliable, stable, and precise attachment and separation of the flight equipment.

[0053] The existing acceleration device includes an acceleration structure, which is provided with a support arm for providing flight power for the flying equipment. After providing power, the support arm will enter the deceleration stage. In order to avoid the support arm from interfering with the movement of the flying equipment during the deceleration stage, an additional power source such as a hydraulic cylinder or a motor is required to drive the support arm down.

[0054] In the above technical solution, since the support arm in the acceleration device needs to be installed with an additional power source such as a hydraulic cylinder and a motor to drive it to be lowered, the structure of the acceleration device is complicated and difficult to install and maintain.

[0055] Therefore, the present application provides a flight equipment acceleration device and method, which is used to solve the problem of the complicated structure of the acceleration device in the prior art and the difficulty in installation and maintenance.

When the sliding rail structure 100 controls the mounting seat 300 to decelerate, the unlocking mechanism 500 slides relative to the mounting seat 300 under the action of inertia and is disengaged from the abutment with the support arm 600, the support arm 600 loses the pushing force and falls down under the action of the pulling force.

[0060] The sliding rail structure comprises a power system, an acceleration sliding rail and a control system, the acceleration structure 200 is arranged on the acceleration sliding rail and is powered and buffered by the power system, and the control system is used for monitoring and adjusting various parameters in the acceleration process, so that the flight equipment can be accurately launched according to the predetermined track path.

[0064] The slide rail structure 100 is used to control the acceleration and deceleration of the mounting base 300, and the acceleration and deceleration control of the mounting base 300 is realized through the slide rail structure 100, which is known in the prior art, and thus will not be described herein.

[0065] In the embodiments provided in the present application, the elastic return mechanism 400 comprises a sliding assembly 410 and a tension spring 420.

[0066] One end of the tension spring 420 is connected with the sliding assembly 410, and the sliding assembly 410 drives the one end of the tension spring 420 to slide in the sliding assembly 410 to exert a pulling force on the support arm 600.

[0067] In the embodiments provided in the present application, the tension spring 420 is a straight tension spring 420, and the tension spring 420 provides a pulling force on the support arm 600 to make the support arm 600 quickly dump in the deceleration stage.

[0068] In the embodiments provided in the present application, the sliding assembly 410 comprises a limiting groove 411, a lead screw 412, a nut and a hand wheel 413.

[0069] The limiting groove 411 is arranged on the mounting base 300, the lead screw 412 is arranged in the limiting groove 411, the hand wheel 413 is located outside the limiting groove 411 and connected with the lead screw 412, the nut is arranged on the lead screw, and the tension spring 420 is connected with the nut. The hand wheel 413 drives the lead screw 412 to rotate to move the nut along the lead screw 412 to drive the one end of the tension spring 420 to move.

[0070] The sliding assembly 410 is connected with the tension spring 420, and the extension and retraction amount of the tension spring 420 is controlled through the sliding assembly 410, so that the tension spring 420 is elongated to have elastic potential energy.

[0071] In the embodiments provided in the present application, the limiting groove 411 is arranged inside the mounting base 300, one end of the lead screw 412 is connected with the groove wall of the limiting groove 411, a hole is arranged on the mounting base 300, the hand wheel 413 passes through the hole and is connected with the other end of the lead screw 412, and the rotation of the hand wheel 413 drives the rotation of the lead screw 412.

[0074] It should be noted that one end of the tension spring 420 is connected to the screw nut, and the extension and retraction of the tension spring 420 is a prior art, which will not be described here.

[0075] As shown in the embodiments provided in the present application, the unlocking mechanism 500 includes a first sliding groove 510, a second sliding groove 520, a first sliding block 530, a second sliding block 540, and a limiting block 550. Figure 3 and Figure 4 As shown in the embodiments provided in the present application, the unlocking mechanism 500 includes a first sliding groove 510, a second sliding groove 520, a first sliding block 530, a second sliding block 540, and a limiting block 550.

[0076] The first sliding groove 510 is located above the second sliding groove 520, the first sliding block 530 is slidingly arranged in the first sliding groove 510, the first sliding block 530 abuts against the support arm 600, and the second sliding block 540 is slidingly arranged in the second sliding groove 520.

[0077] The first sliding groove 510 is provided with a through hole 560 communicating with the second sliding groove 520, and the limiting block 550 is arranged in the through hole 560. The two ends of the limiting block 550 respectively abut against one side of the first sliding block 530 away from the support arm 600 and the top of the second sliding block 540.

[0078] When the slide rail structure 100 controls the mounting seat 300 to accelerate, the elastic return mechanism 400 provides a pulling force to the support arm 600, the first sliding block 530 abuts against the limiting block 550, the first sliding block 530 provides a pushing force to the support arm 600, so that the support arm 600 is lifted up.

[0079] When the slide rail structure 100 controls the mounting seat 300 to decelerate, the second sliding block 540 slides relative to the second sliding groove 520 under the action of inertia, so that the second sliding block 540 is disengaged from the abutment with the bottom of the limiting block 550. The limiting block 550 slides relative to the through hole 560 and slides out of the first sliding groove 510, so that the side wall of the limiting block 550 is disengaged from the abutment with the first sliding block 530, so that the first sliding block 530 slides towards the limiting block 550 and is disengaged from the abutment with the support arm 600.

[0080] The first sliding groove 510 is provided at the bottom of the mounting seat 300, the second sliding groove 520 is provided inside the mounting seat 300, and the second sliding groove 520 is at least partially located below the first sliding groove 510. The first sliding groove 510 and the second sliding groove 520 are communicated through the through hole 560.

[0081] The limiting block 550 is arranged in the through hole 560, and the upper end and the lower end are located in the first sliding groove 510 and the second sliding groove 520 respectively. In the acceleration stage of the acceleration structure 200, the upper end of the limiting block 550 abuts against the side wall of the first sliding block 530, and the lower end of the limiting block 550 abuts against the top of the second sliding block 540, so that the first sliding block 530 abuts against the support arm 600 to make it in an inclined state.

[0082] When the acceleration structure 200 is in the deceleration stage, the second slider 540 continues to slide forward due to inertia, so that the top of the second slider 540 is out of contact with the limit block 550, and the upper end of the limit block 550 falls out of the first slide groove 510. When the first slider 530 is not contacted by the limit block 550, the support arm 600 is no longer pushed by the first slider 530. Under the action of the tension spring 420 and gravity, the support arm 600 quickly falls downward, thereby avoiding movement interference with the rear of the flight equipment.

[0083] like Figure 5 As shown, in the embodiment provided in the present application, the limiting block 550 includes a first abutting portion 551 and a second abutting portion 552 , and the first abutting portion 551 is located above the second abutting portion 552 .

[0084] When the slide rail structure 100 controls the mounting seat 300 to accelerate, the bottom of the second abutting portion 552 abuts against the top of the second sliding block 540 , so that the sidewall of the first abutting portion 551 abuts against the sidewall of the first sliding block 530 .

[0085] When the slide rail structure 100 controls the mounting seat 300 to decelerate, the second slider 540 slides in the direction away from the limit block 550, the second slider 540 disengages from the limit block 550, and the second abutting portion 552 falls, driving the first abutting portion 551 to fall, so that the first abutting portion 551 disengages from the first slider 530.

[0086] The upper end of the first abutting portion 551 abuts against or is out of abutment with the first slider 530 , and the lower end of the second abutting portion 552 abuts against or is out of abutment with the second slider 540 .

[0087] The diameter of the second abutting portion 552 is greater than the diameter of the through hole 560 , which can effectively prevent the limiting block 550 from falling out of the through hole 560 during movement or installation.

[0088] Among them, such as Figure 3 As shown, the first abutment portion 551 of the limit block 550 has a smaller diameter at the upper end and a larger diameter at the lower end. A blocking block 570 is provided in the through hole 560. The blocking block 570 is used to clamp the lower end of the first abutment portion 551 to prevent the first abutment portion 551 from continuing to move upward after reaching a preset position, thereby limiting the height of the upper part of the limit block 550 extending out of the through hole 560.

[0089] In the embodiment provided in the present application, a roller 5511 is provided on the top of the first abutting portion 551 , and the roller 5511 abuts against the first sliding block 530 .

[0090] The friction between the first abutting portion 551 and the first sliding block 530 is reduced by the roller 5511 , so that the first abutting portion 551 can slide out of the first sliding groove 510 along the side wall of the first sliding block 530 more quickly.

[0091] In the embodiments provided in the application, the second abutting portion 552 is provided with an acceleration spring 553 between the second abutting portion 552 and the first sliding groove 510.

[0092] The diameter of the acceleration spring 553 is greater than the diameter of the through hole 560 and less than the diameter of the second abutting portion 552, so as to prevent the acceleration spring 553 from falling off the limiting block 550.

[0093] The acceleration spring 553 makes the limiting block 550 just fall out of the first sliding groove 510, so as to prevent the limiting block 550 from falling into the second sliding groove 520 and causing inconvenience to the reset of the subsequent limiting block 550.

[0094] When the slide rail structure 100 controls the mounting seat 300 to accelerate, the second sliding block 540 abuts against the second abutting portion 552, and the acceleration spring 553 is in a compressed state.

[0095] When the slide rail structure 100 controls the mounting seat 300 to decelerate, the second sliding block 540 is separated from the second abutting portion 552, and the elastic force of the acceleration spring 553 drives the limiting block 550 to accelerate downward, so as to make the first abutting portion 551 of the limiting block 550 separate from the first sliding block 530 more quickly, and effectively improve the unlocking speed of the unlocking mechanism 500.

[0096] In the embodiments provided in the application, the top of the first sliding block 530 is provided with an inclined surface, which abuts against or separates from the supporting arm 600.

[0097] The angle between the inclined surface and the horizontal plane is 60-90 degrees, which is set according to actual requirements, so as to form an inclined angle between the supporting arm 600 and the horizontal plane.

[0098] It should be noted that the top of the supporting arm 600 is provided with an L-shaped groove, at least part of the front end of the flight equipment is placed in the L-shaped groove, and the flight equipment is in a horizontal state. During the advancing process of the acceleration structure 200, the side wall of the L-shaped groove provides an acceleration thrust for the flight equipment.

[0099] In the embodiments provided in the application, the first sliding groove 510 is provided with a first spring 511, and the second sliding groove 520 is provided with a second spring 521. The first spring 511 is used to prevent the first sliding block 530 from colliding with the groove wall of the first sliding groove 510, and the second spring 521 is used to prevent the second sliding block 540 from colliding with the groove wall of the second sliding groove 520.

[0100] During the deceleration process, the first sliding block 530 and the second sliding block 540 will continue to slide forward under the action of inertia. In order to avoid excessive impact force and cause damage to the first sliding groove 510 and the second sliding groove 520, the first spring 511 and the second spring 521 are arranged to respectively buffer the first sliding block 530 and the second sliding block 540.

[0101] It should be noted that the acceleration structure provided in the present application can be installed at the front end and the rear end of the flight equipment, or at both ends.

[0102] The embodiment also provides a flight equipment acceleration method applied to the flight equipment acceleration device.

[0103] The slide rail structure 100 is used to control the acceleration or deceleration of the acceleration structure 200.

[0104] When the slide rail structure 100 controls the acceleration of the mounting seat 300, the elastic return mechanism 400 exerts a pulling force on the support arm 600, and the unlocking mechanism 500 abuts against the support arm 600 to exert a pushing force on the support arm 600, so that the support arm 600 is lifted up.

[0105] When the slide rail structure 100 controls the deceleration of the mounting seat 300, the unlocking mechanism 500 slides relative to the mounting seat 300 under the action of inertia and is disengaged from the support arm 600, and the support arm 600 loses the pushing force and falls down under the action of the pulling force.

[0106] The specific action of the acceleration structure 200 when the flight equipment takes off is that when the flight equipment reaches the acceleration condition, that is, the acceleration structure 200 enters the deceleration stage from the acceleration stage, the acceleration structure 200 starts to decelerate until it stops, and a speed difference is generated between the acceleration structure 200 and the flight equipment.

[0107] The second sliding block 540 in the acceleration structure 200 continues to displace forward due to inertia, one side of the acceleration spring 553 loses pressure, the limiting block 550 rapidly falls down under the combined action of the elastic force and the gravity, and the first sliding block 530 dislocates forward due to inertia without being blocked. The support arm 600 is not blocked by the first sliding block 530 and rapidly tilts down under the action of the pulling force of the tension spring 420, and the trolley is automatically disengaged from the bottom of the flight equipment.

[0108] In summary, the tilting process of the support arm 600 in the flight equipment acceleration device provided in the present application is completely powered by the inertia of the device itself, without the need for additional power sources such as hydraulic cylinders and motors, the device has low energy consumption, wide application range, and is convenient to install and maintain.

[0109] The tilting of the support arm 600 adopts the inertia unlocking mechanism 500, which can quickly unlock the trolley support arm 600 in the deceleration stage of the trolley, avoids collision with the flight equipment, and improves the reliability without increasing the complexity of the structure.

[0110] And the flexible connection of the upper and lower parts of the mounting seat 300 is realized by the tension spring 420, which avoids the adverse effects caused by bumps during sliding.
