Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] like Figures 1 to 5 As shown, in this embodiment, the pod shock-absorbing structure includes a pod mounting platform 1, a pod 2 is mounted on the pod mounting platform 1, the pod mounting platform 1 includes a primary shock-absorbing mechanism 3, the primary shock-absorbing mechanism 3 includes a primary shock-absorbing base frame 5 and a primary shock-absorbing mounting frame 6, the primary shock-absorbing mounting frame 6 is located above the primary shock-absorbing base frame 5, a plurality of shock-absorbing ball mounting frames 7 are obliquely arranged between the primary shock-absorbing mounting frame 6 and the primary shock-absorbing base frame 5, and shock-absorbing balls 8 are arranged on the plurality of shock-absorbing ball mounting frames 7.

[0032] With respect to the deficiencies of the prior art, in the present invention, a plurality of shock-absorbing ball mounting frames 7 are obliquely arranged between the primary shock-absorbing mounting frame 6 and the primary shock-absorbing base frame 5, so that the plurality of shock-absorbing balls 8 located on the plurality of shock-absorbing ball mounting frames 7 can provide buffering when subjected to impacts in the vertical and horizontal directions, so that the pod shock-absorbing structure has the advantages of good shock-absorbing effect and improved pod stability.

[0033] like Figures 2 to 3 As shown, in some embodiments, the pod mounting platform 1 further includes a secondary shock absorbing mechanism 9 arranged on the primary shock absorbing mechanism 3, the secondary shock absorbing mechanism 9 includes a secondary shock absorbing mounting frame 10, a fuselage connecting plate 11 and two secondary shock absorbing arms 12, the secondary shock absorbing mounting frame 10 is arranged opposite to the fuselage connecting plate 11, one end of the two secondary shock absorbing arms 12 are both connected to the secondary shock absorbing mounting frame 10, and the other end is connected to the lower part of the fuselage connecting plate 11 through a secondary shock absorbing column 13, and a secondary shock absorbing buckle 15 is connected between the upper part of the fuselage connecting plate 11 and the secondary shock absorbing mounting frame 10. Among them, the fuselage connecting plate 11 is used to be connected to the main body of the drone.

[0034] It should be noted that when the primary shock absorbing mechanism 3 is subjected to an excessive impact, the impact energy can be absorbed by the secondary shock absorbing mechanism 9 to achieve a stronger shock absorbing effect. Specifically, the secondary shock absorbing column 13 and the secondary shock absorbing buckle 15 are used to achieve the secondary shock absorbing effect.

[0035] like Figures 2 to 3 As shown, in some embodiments, the two secondary shock absorbing arms 12 are connected to the primary shock absorbing chassis 5, the primary shock absorbing chassis 5, the secondary shock absorbing mounting frame 10 and the two secondary shock absorbing arms 12 form a lever structure, and the connection point between the two secondary shock absorbing arms 12 and the primary shock absorbing chassis 5 is used as the fulcrum 14. Specifically, the lever structure formed by the primary shock absorbing chassis 5, the secondary shock absorbing mounting frame 10 and the two secondary shock absorbing arms 12 can convert the vertical vibration tendency of the pod 2 into the tendency of rotation along the fulcrum 14. Since the tendency of rotation is smoother during movement, the impact on the visual effect is smaller; moreover, through the setting of the above-mentioned lever structure, the energy absorption and shock absorbing effect of the secondary shock absorbing mounting frame 10 and the secondary shock absorbing buckle 15 on the primary shock absorbing mechanism 3 and the pod 2 will be multiplied by a force arm factor, thereby improving the shock absorbing effect, thereby improving the stability of the pod.

[0036] like Figures 2 to 3 As shown, in some embodiments, the two secondary shock absorbing columns 13 are located close to the fulcrum 14. Specifically, by placing the two secondary shock absorbing columns 13 close to the fulcrum 14, on the one hand, a shock absorbing effect can be achieved, and on the other hand, the direct impact of the fulcrum 14 on the fuselage connecting plate 11 can be avoided, thereby playing a buffering and protective role.

[0037] like Figure 6 to Figure 7 As shown, in some embodiments, the secondary shock-absorbing buckle 15 includes a first fastener 16, a second fastener 17 and a shock-absorbing column 18, wherein the first fastener 16 is connected to the secondary shock-absorbing mounting frame 10, and the opening of the first fastener 16 faces the secondary shock-absorbing mounting frame 10, the second fastener 17 is connected to the fuselage connecting plate 11, and the opening of the second fastener 17 faces the fuselage connecting plate 11, the opening of the first fastener 16 is engaged with the opening of the second fastener 17, and the shock-absorbing column 18 is connected between the first fastener 16 and the second fastener 17. The shock-absorbing column 18 is located in the opening of the first fastener 16 and the opening of the second fastener 17 at the same time. Specifically, when the pod 2 is connected to the primary shock absorbing mechanism 3, the secondary shock absorbing mounting frame 10 and the secondary shock absorbing buckle 15 connected thereto have a tendency to rotate toward the pod 2, thereby squeezing the shock absorbing column 18 located between the first fastener 16 and the second fastener 17, and then being fixed under the action of the secondary shock absorbing buckle 15 connected to the fuselage connecting plate 11.

[0038] It is worth mentioning that since the shock absorbing material / mechanism usually achieves shock absorption by squeezing energy absorption, although it can also be achieved by spring stretching, its energy absorption and shock absorption effect is weak, and the spring stretching is prone to fatigue and has a limited life. Therefore, by setting the secondary shock absorbing buckle 15, the separation trend of the secondary shock absorbing mounting frame 10 and the fuselage connecting plate 11 is converted into the approach trend of the first fastener 16 and the second fastener 17, and then the stretching of the secondary shock absorbing mounting frame 10 and the fuselage connecting plate 11 is converted into the squeezing of the shock absorbing column 18 between the first fastener 16 and the second fastener 17, thereby improving the stability of the connection, the shock absorbing effect and the life of the shock absorbing mechanism.

[0039] like Figures 4 to 5 As shown, in some embodiments, the bottom of the pod mounting platform 1 is connected to the pod 2 via a pod connecting portion 19, and an unlocking mechanism 20 is also provided on the pod mounting platform 1, and the unlocking mechanism 20 is used to unlock the pod 2. Specifically, the unlocking of the pod 2 is triggered by the unlocking mechanism 20, so that the pod 2 can be separated from the pod connecting portion 19.

[0040] like Figures 4 to 5 As shown, in some embodiments, the unlocking mechanism 20 includes a lever bracket 21, a lever 22 is rotatably connected to the lever bracket 21, one end of the lever 22 has a toggle portion 23, and the other end has a trigger end 25, and an unlocking trigger switch 26 is provided on the pod mounting platform 1, and the trigger end 25 triggers the unlocking trigger switch 26 to unlock when the toggle portion 23 is toggled. Specifically, since the unlocking mechanism 20 of the prior art is often provided near the pod 2 or the pod connection portion 19, it is inconvenient to operate; at the same time, in the present invention, by toggling the toggle portion 23 of the lever 22, the trigger end 25 of the lever 22 is rotated to trigger the unlocking trigger switch 26 to achieve unlocking. Therefore, the present invention can expand the operation range and increase the convenience of operation by toggling the lever 22 to achieve unlocking.

[0041] like Figures 4 to 5 As shown, in some embodiments, a limit feedback protrusion 27 is provided on the lever bracket 21, and the lever 22 is limited by the limit feedback protrusion 27 when the trigger end 25 triggers the unlock trigger switch 26. Specifically, the limit feedback protrusion 27 is used to limit the position of the lever 22 and give the operator feedback that the lever 22 is in place; when the operator moves the lever 22 to the limit feedback protrusion 27, the trigger end 25 of the lever 22 presses the unlock trigger switch 26, thereby releasing the lock of the pod 2, and the operator can remove the pod 2.

[0042] like Figures 1 to 4As shown, in some embodiments, a plurality of the shock absorbing balls 8 are arranged around the primary shock absorbing mounting frame 6. Specifically, the number of the shock absorbing balls 8 can be four, and the four shock absorbing balls 8 are arranged around the primary shock absorbing mounting frame 6.

[0043] In addition, the present invention also provides a drone, which includes a main body and the pod shock absorbing structure, wherein the main body is connected to the body connecting plate 11.

[0044] The specific structure of the drone is referred to the above embodiments. Since the drone adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
