Abstract

This invention discloses a landing gear and a racing drone, belonging to the field of racing drones. It includes two mounting beams positioned front and rear at the bottom of the drone's fuselage; two support rods symmetrically mounted on one of the mounting beams; two telescopic components symmetrically mounted on the other mounting beam; and two base plates symmetrically mounted at the bottom ends of the support rods and telescopic components. The support rods and telescopic components are arranged in pairs, with each base plate simultaneously universally connected to the bottom end of one pair of support rods and telescopic components. The telescopic components extend and retract to adjust their axial length, changing the tilt angle of the base plate relative to the plane of the two mounting beams. This invention adjusts the forward tilt angle of the racing drone by extending and retracting the length of the rear support legs, enabling optimal launch at the forward tilt angle under different load conditions.

Description

Technical Field

[0001] This utility model relates to the field of racing drone technology, and in particular to a racing drone landing gear and a racing drone. Background Technology

[0002] Racing drones are multi-rotor aircraft used in high-speed flight scenarios. In many scenarios, racing drones need to maintain a certain forward tilt angle before takeoff and achieve a rapid catapult takeoff effect by instantaneously throttle full power.

[0003] To achieve rapid catapult takeoff in different scenarios, existing racing drones require additional supports to position the aircraft at a specific angle. For some special application scenarios, due to differences in load distribution characteristics, the forward tilt angle required for rapid catapult takeoff also varies. Current fixed landing gear cannot quickly respond to the rapid catapult takeoff requirements of racing drones in multiple application scenarios. Utility Model Content

[0004] In view of this, this utility model proposes a racing drone landing gear and a racing drone to solve the current problem of needing to use an additional support to mount the racing drone at a specific angle so that it can be launched at high speed.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a landing gear for a racing drone, including two mounting beams, which are set at the bottom of the racing drone body; two support rods, symmetrically arranged on one of the mounting beams; two telescopic components, symmetrically arranged on the other mounting beam; and two base plates, symmetrically arranged at the bottom ends of the support rods and telescopic components. The support rods and telescopic components are arranged in pairs, and each base plate is simultaneously universally connected to the bottom end of a pair of support rods and telescopic components. The telescopic components extend and retract to adjust their axial length, and change the tilt angle of the base plate relative to the plane containing the two mounting beams.

[0006] Based on the above technical solutions, preferably, the telescopic component includes a sleeve, which is mounted on the mounting beam; a sliding rod, one end of which is fitted inside the sleeve and the other end is universally connected to the base plate; and an elastic element, which is fitted inside the sleeve and positioned between the inner end of the sleeve and the insertion end of the sliding rod; wherein the sliding rod moves axially relative to the sleeve and adjusts the axial length of the telescopic component.

[0007] More preferably, when the axial length of the telescopic component and the support rod are the same, the elastic element is in a relaxed state.

[0008] More preferably, the telescopic assembly further includes a limiting member disposed on the outer peripheral wall of the slide rod; wherein, a first sliding groove is formed on the outer peripheral wall of the sleeve along its axial direction, the limiting member passes through the first sliding groove and connects with the outer peripheral wall of the slide rod, and the limiting member moves along the first sliding groove; a retaining groove is also formed on the outer peripheral wall of the sleeve, the retaining groove extending in a direction perpendicular to the extending direction of the first sliding groove, the retaining groove communicating with the first sliding groove, the limiting member rotating axially with the slide rod and moving from the first sliding groove into the retaining groove, and restricting the movement of the slide rod within the sleeve.

[0009] In a further preferred embodiment, the slot is connected to the end of the first sliding groove near the base plate, and when the axial length of the telescopic component is the same as that of the support rod, the limiting member is located in the slot.

[0010] More preferably, the first groove is located on the part of the sleeve near the bottom plate, and the length of the first groove is no more than half of the axial length of the sleeve.

[0011] In a further preferred embodiment, the outer peripheral wall of the slide bar is in close contact with the inner peripheral wall of the sleeve, and the outer diameter of the elastic element is equal to the inner diameter of the sleeve.

[0012] Based on the above technical solutions, preferably, it also includes a slider, which is disposed between the base plate and the end of the telescopic component; wherein, a second sliding groove is formed on the base plate along its axial direction; the slider is universally connected to the end of the telescopic component, and the slider is movably disposed in the second sliding groove and moves along the second sliding groove.

[0013] More preferably, it also includes a connector, one end of which is a threaded rod and the other end is a ball head; wherein, the slider has a groove; the ball head of the connector is fitted into the groove and allows the connector to rotate omnidirectionally relative to the slider, and one end of the threaded rod of the connector is threadedly fastened to the end of the telescopic assembly.

[0014] On the other hand, this utility model provides a racing drone that uses the aforementioned racing drone landing gear.

[0015] The landing gear and racing drone of this utility model have the following advantages over the prior art:

[0016] (1) This utility model sets the two rear outriggers of the racing drone as retractable structures. According to the load of the racing drone, the forward tilt angle of the racing drone can be adjusted by extending and retracting the length of the rear outriggers. This enables the racing drone to be launched with the optimal forward tilt angle under different load conditions. After the racing drone leaves the ground, as the load on the landing gear is released, the landing gear will automatically return to the state of consistent front and rear height in the air, ensuring that the racing drone can still land safely in a horizontal attitude.

[0017] (2) The telescopic component of this utility model is a sliding rod and a sleeve that are elastically connected through an elastic element. Therefore, under different load conditions, the larger the load at the rear of the racing machine is relative to the front, the greater the compressive force on the elastic element, which compresses the elastic element and changes the length of the telescopic component located at the rear of the racing machine, thereby adjusting its launch angle according to the load at the rear of the racing machine.

[0018] (3) A slider is provided between the bottom end of the telescopic component and the base plate of this utility model, so that after the length of the telescopic component changes, the slider can move relative to the base plate and adjust the position of the slider on the base plate, so that the base plate will not hinder the telescopic component from expanding and contracting.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1 As shown, combined with Figure 2 and Figure 3This utility model discloses a landing gear for a racing drone, comprising two mounting beams 1, positioned front and rear at the bottom of the drone body, which are typically detachably connected to the drone's bottom mounting area via fastening bolts; two support rods 2, symmetrically mounted on one of the mounting beams 1; two telescopic components 3, symmetrically mounted on the other mounting beam 1; and two base plates 4, symmetrically mounted at the bottom ends of the support rods 2 and telescopic components 3. The support rods 2 and telescopic components 3 are arranged in pairs, with each base plate 4 simultaneously universally connected to the bottom end of one pair of support rods 2 and telescopic components 3. The support rods 2 and telescopic components 3 are generally perpendicular to the plane containing the mounting beams 1. However, since the base plates 4 are universally connected to the bottom of the support rods 2 and telescopic components 3, the support rods 2 or telescopic components 3 can also be inclined relative to the mounting beams 1, forming an outwardly forked structure. The telescopic components 3 extend and retract to adjust their axial length, causing the inclination angle of the base plates 4 relative to the plane containing the two mounting beams 1 to change. Since the mounting beam 1 connected to the telescopic assembly 3 is located at the rear of the racing drone, changing the axial length of the telescopic assembly 3 can adjust the upward tilt angle of the racing drone during catapult takeoff to meet the needs of different load conditions of the racing drone.

[0026] exist Figure 3 In a preferred embodiment shown, the telescopic assembly 3 includes a sleeve 31 mounted on the mounting beam 1; a sliding rod 32, one end of which is fitted inside the sleeve 31 and the other end is universally connected to the base plate 4; and an elastic element 33, fitted inside the sleeve 31 and positioned between the inner end of the sleeve 31 and the insertion end of the sliding rod 32. The sliding rod 32 moves axially relative to the sleeve 31, adjusting the axial length of the telescopic assembly 3. Typically, the heavier the load on the racing drone, the greater the tilt angle required for its launch. In this embodiment, the inner end of the sleeve 31 and the insertion end of the sliding rod 32 are connected by the elastic element 33. Therefore, the elastic element 33 will compress under the applied gravity, causing the sliding rod 32 to slide into the sleeve 31, thereby shortening the length of the telescopic assembly 3. Meanwhile, the length of the support rod 2 at the front of the racing drone remains unchanged, while the length of the telescopic assembly 3 at the rear of the racing drone decreases, causing the racing drone to change from a level view to a state with its nose tilted upwards. The greater the load on the racing machine, the greater the compression of the elastic element 33, the more significant the reduction in the length of the telescopic component 3, and the greater the forward tilt angle of the racing machine.

[0027] exist Figure 2 In a preferred embodiment shown, when the axial lengths of the telescopic component 3 and the support rod 2 are the same, the elastic element 33 is in a relaxed state. In this case, the four legs supporting the racing drone are of equal length, keeping the racing drone in a level position. Therefore, under no-load conditions, the racing drone does not need to increase its forward tilt angle to improve its catapult takeoff speed.

[0028] exist Figure 3In one preferred embodiment shown, under certain operating conditions, the racing drone does not need to use a large forward tilt angle catapult for takeoff and can take off and land on flat ground. Therefore, it is necessary to ensure that the four outriggers of the racing drone do not have length differences due to changes in their load. Therefore, in this embodiment, the telescopic assembly 3 also includes a limiting member 34, which is disposed on the outer peripheral wall of the slide rod 32. A first sliding groove 301 is formed along the axial direction on the outer peripheral wall of the sleeve 31. The limiting member 34 passes through the first sliding groove 301 and connects to the outer peripheral wall of the slide rod 32, and moves along the first sliding groove 301. A slot 302 is also formed on the outer peripheral wall of the sleeve 31. The extending direction of the slot 302 is perpendicular to the extending direction of the first sliding groove 301. The slot 302 is connected to the first sliding groove 301. The limiting member 34 rotates axially with the slide rod 32 and moves from the first sliding groove 301 into the slot 302. The limiting member 34 is engaged in the slot 302, restricting the movement of the slide rod 32 within the sleeve 31, so that the length of the telescopic assembly 3 does not change due to variations in the load of the traveling machine.

[0029] exist Figure 3 In a preferred embodiment shown, the slot 302 is connected to the end of the first slide groove 301 near the base plate 4. When the axial lengths of the telescopic component 3 and the support rod 2 are the same, the limiting member 34 is located in the slot 302. When the limiting member 34 is locked in the slot 302 and the position of the slide rod 32 in the sleeve 31 is locked, the telescopic component 3 and the support rod 2 have the same length, so that the traverse machine is in a horizontal position.

[0030] exist Figure 3 In a preferred embodiment shown, the first groove 301 is located on the part of the sleeve 31 near the base plate 4. The length of the first groove 301 is no more than half of the axial length of the sleeve 31, which limits the telescopic length range of the telescopic component 3 and avoids the problem that the large load of the racing machine will cause the forward tilt angle of the racing machine to be too large, which will hinder its launch.

[0031] exist Figure 3 In a preferred embodiment shown, the outer peripheral wall of the slide bar 32 is in close contact with the inner peripheral wall of the sleeve 31. The elastic element 33 is generally a spring. The outer diameter of the elastic element 33 is equal to the inner diameter of the sleeve 31, so that the diameter of the elastic element 33 is not too small, and the elastic element 33 will not be twisted in the sleeve 31 during compression, so that the length of the telescopic component 3 cannot change according to the working conditions of the racing machine.

[0032] exist Figure 2In a preferred embodiment shown, a slider 5 is further included, disposed between the ends of the base plate 4 and the telescopic component 3. A second groove 401 is formed on the base plate 4 along its axial direction. The slider 5 is universally connected to the ends of the telescopic component 3, and is movably disposed within and along the second groove 401. Since the relative tilt angle between the base plate 4 and the plane containing the two mounting beams 1 changes when the forward tilt angle of the trekking machine changes, the connection point between the base plate 4 and the bottom of the telescopic component 3 also changes accordingly. Furthermore, the larger the forward tilt angle of the trekking machine, the more pronounced the relative offset between the connection point between the base plate 4 and the bottom of the telescopic component 3. Therefore, the slider 5 movably connects the base plate 4 and the bottom of the telescopic component 3, ensuring that the extension and retraction of the telescopic component 3 is not obstructed by the base plate 4.

[0033] exist Figure 3 In a preferred embodiment shown, a connector 6 is further included, with one end being a threaded rod and the other end being a ball head; wherein, a groove 501 is provided on the slider 5; the ball head of the connector 6 is fitted into the groove 501 and allows the connector 6 to rotate omnidirectionally relative to the slider 5; one end of the threaded rod of the connector 6 is threadedly fastened to the end of the telescopic component 3; and the connector 6 realizes the omnidirectional connection between the end of the telescopic component 3 and the slider 4.

[0034] like Figure 1 As shown, combined with Figure 2 and Figure 3 The present invention provides a racing drone that adopts a racing drone landing gear according to any of the above embodiments.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
