Definitions
- the present invention relates to the field of drone technology, and more particularly to a small drone buffer stand.
- UAVs are unmanned aircraft operated by radio remote control equipment and self-provided program control devices. Civil drones have important applications in aerial photography, agriculture, plant protection, disaster relief, etc. The UAVs currently used are especially small. In the drone, the tripod is not provided with a buffer structure or the buffer structure is unreasonable, and the rollover is likely to occur when landing.
- the technical problem to be solved by the present invention is to provide a small UAV buffering stand with a good cushioning effect against the above-mentioned drawbacks of the prior art.
- a small drone buffering tripod comprising a mounting seat and two struts arranged side by side; wherein the struts are vertically fixedly provided with arc connecting rods; and further comprising splicing two of the connecting rod ends a sleeve of the connecting portion; two end portions of the connecting rod are connected by a spring; a surface of the connecting rod is provided with a limit ring; the inner wall of the sleeve is provided with a plurality of elastic ribs that cooperate with the limiting ring; The lower surface of the mount is provided with a cavity and a cover that match the outer shape of the sleeve.
- the small drone buffering tripod of the present invention wherein the lower surface of the strut is provided with a plurality of grooves, and the groove is provided with a shock absorbing strip.
- the small drone buffering stand according to the present invention wherein the shock absorbing strip surface is provided with a PVC coating.
- the utility model has the beneficial effects that when the drone falls, the strut is in contact with the ground, and the generated vibration is transmitted through the arc connecting rod, and the spring and the elastic ribs are used for buffering and absorbing, thereby greatly reducing the vibration impact during the falling, and preventing the occurrence side. Turning over; connecting and installing through the cavity and the sleeve, the disassembly and assembly is more convenient and convenient for storage; the overall structure is simple and the cost is low.
- FIG. 1 is a schematic view showing the structure of a small UAV buffering stand according to a preferred embodiment of the present invention.
- the small unmanned aerial vehicle buffering stand of the preferred embodiment of the present invention comprises a mounting seat 1 and two struts 2 arranged side by side.
- the struts 2 are vertically fixedly provided with a curved connecting rod 3;
- the sleeve 4 of the two connecting rods 3 is sleeved; the ends of the two connecting rods 3 are connected by a spring 30;
- the surface of the connecting rod 3 is provided with a limit ring 31;
- the inner wall of the sleeve 4 is provided with a plurality of matching rings 31 Elastic ribs 40;
- the lower surface of the mounting seat 1 is provided with a cavity 10 and a cover plate (not shown) matching the outer shape of the sleeve 4; when the drone is lowered, the struts 2 are in contact with the ground, and the generated vibration passes.
- the arc connecting rod 3 is conducted, and the spring 30 and the elastic rib 40 are used for buffering and absorbing, which greatly reduces the influence of vibration during
- the lower surface of the strut 2 is provided with a plurality of grooves 20, and the shock absorbing strips 21 are disposed in the recesses 20, and the initial shock absorption is performed when landing, thereby improving the shock absorbing effect.
- the surface of the shock absorbing strip 21 is provided with a PVC coating to prevent friction with the ground and damage the shock absorbing strip 21.

Abstract
La présente invention concerne un support de pied d'amortissement pour un petit véhicule aérien sans pilote comprenant une base de montage (1) et deux tiges de support (2) qui sont disposées en parallèle; des tiges de raccordement en arc (3) sont disposées verticalement et de manière fixe sur les tiges de support (2); un manchon (4) gainé sur les extrémités des deux tiges de raccordement (3); les extrémités des deux tiges de raccordement (3) sont raccordées au moyen d'un ressort (30); une surface des tiges de raccordement (3) est pourvue d'une bague de retenue (31); une paroi interne du manchon (4) est pourvue d'une pluralité de nervures élastiques (40) correspondant à la bague de retenue (31); une surface inférieure de la base de montage (1) est pourvue d'une cavité (10) correspondant à un contour du manchon (4) et une plaque de recouvrement. Lorsque le véhicule aérien sans pilote atterrit, les tiges de support (2) entrent en contact avec le sol, la vibration générée est transmise au moyen des tiges de raccordement en arc (3), et la vibration est amortie au moyen du ressort (30) et des nervures élastiques (40), réduisant ainsi largement l'effet de vibration pendant l'atterrissage et empêchant le véhicule de se retourner. La structure globale de l'invention est simple, et son coût est faible.
