Description

Technical Field

[0001] The utility model relates to an unmanned aerial vehicle (UAV), in particular to a four-rotor UAV for surveying and mapping. Background Art

[0002] With the continuous development of drone technology, its application in various fields is becoming increasingly widespread, particularly in surveying and mapping. However, traditional quadrotor drones often face issues with stability and cushioning during surveying and mapping operations. In complex and changing environments, such as mountains, jungles, or densely built-up urban areas, drones are subject to external shock and vibration during landing, which not only affects the accuracy of surveying and mapping data but can also cause damage to the drone itself.

[0003] In view of this, we proposed a new technical solution by designing a sophisticated buffer mechanism to significantly enhance the stability and buffering effect of the quadrotor drone. Utility Model Content

[0006] Buffer mechanisms are fixedly provided on the four sides of the quad-rotor drone;

[0007] The buffer mechanism includes a side support frame, which is fixedly arranged on the side of the quadrotor drone; the side support frame is provided with an inner support plate;

[0008] An upper support arm is provided at the upper end of the inner support plate, and a lower support arm is provided at the lower end of the inner support plate.

[0009] The ends of the lower support arm and the upper support arm are rotated together to provide an outer support plate;

[0010] The upper end of the outer support plate is hingedly provided with an upper secondary spring damping shock absorber through a hinged connection, and the lower end of the outer support plate is hingedly provided with an external support arm through a hinged connection. The end of the external support arm and the end of the upper secondary spring damping shock absorber are rotated together to form an external support plate. The external support plate and the lower support arm are connected by a middle secondary spring damping shock absorber, and an external secondary spring damping shock absorber is fixed on the external support plate.

[0011] As an improvement, the inner support plate is arranged vertically.

[0012] As an improvement, the extending direction of the lower support arm and the extending direction of the upper support arm are parallel to each other.

[0013] As an improvement, the inner support plate, the upper support arm, the lower support arm and the outer support plate form a parallelogram structure.

[0014] As an improvement, a support foot is provided at the lower end of the external secondary spring damping shock absorber.

[0015] The advantages of this utility model over existing technologies include: Stability and cushioning provided by the buffer mechanism: The buffer mechanism designed for this quadcopter significantly enhances stability during flight, especially in complex environments or unexpected situations. The flexibility of the parallelogram structure: The parallelogram structure consisting of the inner support plate, upper support arm, lower support arm, and outer support plate is not only strong but also highly flexible. This design allows the structure to undergo a certain degree of elastic deformation when subjected to external forces, effectively absorbing and dissipating impact forces, preventing serious damage to the drone in the event of a collision.

[0016] The superior shock absorption effect of the two-stage spring damper: The upper two-stage spring damper and the outer two-stage spring damper, among other components, effectively reduce vibrations during landing or collisions by leveraging the properties of spring and damping materials.

[0030] A quad-rotor drone for surveying and mapping, comprising a quad-rotor drone 101 and a surveying device 102 fixed to its underside. Furthermore, the quad-rotor drone is characterized in that buffer mechanisms 200 are installed on all four sides to provide additional stability and a cushioning effect.

[0031] The specific structure of the buffer mechanism 200 is as follows:

[0032] First, the main frame of the buffer mechanism 200 is composed of a side support frame 201, which is firmly mounted on the side of the quadrotor drone 101. On the side support frame 201, an inner support plate 202 is provided, which is in a vertical state.

[0033] The inner support plate 202 is connected to an upper support arm 203 and a lower support arm 204 at its upper and lower ends, respectively. These two support arms extend parallel to each other. A rotatable outer support plate 205 is connected to the ends of the lower support arm 204 and the upper support arm 203.

An outer secondary spring damping shock absorber 210 is also fixed to the outer support plate 208, and a support foot 211 is provided at its lower end.

[0036] Overall, this quadcopter drone can provide a very good buffering effect when the drone lands or collides through the carefully designed buffer mechanism 200, especially the multiple secondary spring damping shock absorbers contained therein, thereby protecting the drone and its onboard mapping equipment 102 from damage.

[0038] The superior shock absorption effect of the two-stage spring damper: The upper two-stage spring damper 206 and the outer two-stage spring damper 210, among other components, leverage the properties of spring and damping materials to effectively reduce vibrations during landing or collisions. This design not only protects the drone's precision instruments but also ensures the proper functioning of the surveying and mapping equipment 102 in the face of bumps and unexpected situations.

[0039] Comprehensive protection for drones and mapping equipment: By integrating multiple secondary spring-damped shock absorbers, this drone provides excellent cushioning during landing or collisions. This comprehensive protection significantly extends the drone's service life.
