[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device. It is widely used in industries such as unmanned delivery, surveying and mapping, and scientific research. In order to prevent the drone from falling from a high altitude due to various unexpected factors and causing safety accidents, most industries will equip the drone with a parachute module so that the drone can land smoothly on the ground. However, the current parachute module is basically developed separately as a sub-module for assembly and testing considerations, and then the finished sub-module is installed outside the drone shell. It is relatively independent of the whole machine and gradually cannot meet the requirements for the integrity of the whole machine and the increasingly high appearance of the whole machine. In addition, the parachute module separately set on the outside of the drone shell may fall off the drone due to the unreliable connection between the two, posing a risk of injury. Summary of the invention

[0003] The purpose of the present invention is to provide a drone shell and a drone, so that a parachute module can be installed inside the drone shell through the design of the shell, thereby improving the integrity and appearance of the drone and the parachute module, and avoiding the parachute module from falling off the drone.

[0004] In order to achieve the above-mentioned object, the first aspect of the present disclosure provides a housing of a drone, comprising:

[0005] a shell body; and

DETAILED DESCRIPTION

[0033] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0034] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the corresponding component outline. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0035] According to a first aspect of the present disclosure, a housing of an unmanned aerial vehicle is provided, referring to Figure 1-Figure 7 As shown, the shell of the drone includes a shell body 1 and a top cover 2, wherein the top cover 2 has an open state and a closed state relative to the shell body 1, and the top cover 2 can switch from the closed state to the open state under the impact of the parachute module opening process; in the open state, the top cover 2 is displaced relative to the shell body 1 to form an opening on the shell body 1, and the opening is used for the parachute of the parachute module to pass through from the inner side of the shell body 1 to open on the outer side of the shell body 1, and in the closed state, the top cover 2 covers the opening.

[0036] Through the above technical solution, when the drone is operating normally, the parachute module is located on the inner side of the shell body 1, that is, located inside the drone, and the top cover 2 is in a closed state. When the drone falls from a high altitude due to unexpected factors, the parachute in the parachute module will open, and then the top cover 2 will be impacted by the parachute module and converted from a closed state to an open state, thereby forming an opening on the shell body 1, and the parachute can pass through the opening from the inner side of the shell body 1 and open outside the shell body 1, thereby slowing down the falling speed of the drone and avoiding the occurrence of safety accidents. Since the parachute module is always located in the shell body 1 during the normal operation of the drone, the integrity between the drone and the parachute module is improved, which is conducive to accelerating the integration process of the drone, and the parachute module can be arranged inside the shell, thereby improving the aesthetics of the drone. In addition, because there is no need to separately set the parachute module outside the drone shell, there will be no situation where the parachute module falls from the drone due to the unreliable connection between the drone shell and the parachute module, thereby improving the safety performance of the drone during operation.

[0037] Among them, the parachute can be opened in a variety of ways. For example, the parachute module can use high-pressure gas as a power source to drive the parachute to open. During the fall of the drone, the parachute module will generate a large amount of high-pressure gas through the gas generator. Under the impact of the high-pressure gas and the parachute, the top cover 2 will be converted from a closed state to an open state;

[0038] Alternatively, the parachute module can also use the elastic member as a power source to drive the parachute to open. When the drone is falling, the top cover 2 will be affected by the elastic force of the elastic member and the impact of the parachute, thereby switching from a closed state to an open state.

[0039] In an embodiment of the present disclosure, in order to facilitate the switching of the state of the top cover 2 after being impacted, the shell further includes a connecting structure 3. In a closed state, the top cover 2 is connected to the shell body 1 via the connecting structure 3. The connecting structure 3 is configured to enable the top cover 2 to switch from a closed state to an open state under the impact of the parachute module opening process. The connecting structure 3 can be connected to the shell in a variety of ways. For example, in some embodiments not shown, the connecting structure 3 can be an articulated structure connected to the shell via a hinge, so that the top cover 2 can be directly connected to the shell body 1 in a hinged manner. In this way, during the opening of the parachute, the top cover 2 will flip outward relative to the interior of the shell body 1, thereby forming an opening on the shell body 1 through which the parachute can pass.

[0040] Or, if Figure 4-Figure 7 As shown, the connecting structure 3 can be a breakable structure, which can be broken under the impact of the umbrella opening process to allow the top cover 2 to separate from the shell body 1, and the breakable connecting structure 3 is surrounded on the shell to form a top cover area for forming the top cover 2, so that the surrounding side of the top cover 2 is provided with a breakable connecting structure 3, so that the top cover 2 can be more easily separated from the shell body 1 after being impacted.

[0041] The top cover area can be configured in any shape, such as a rectangle, a triangle, an ellipse, etc., or, as Figure 1 , Figure 2 as well as Figure 4 As shown, the top cover area is constructed as a ring that matches the parachute module, so that the effective area of ​​the top cover 2 can be maximized (that is, the parachute can make full use of the opening area on the shell body 1 when it is in the open state). The present disclosure does not specifically limit the shape of the top cover area, as long as the area enclosed by it can allow the parachute to pass through it.

[0042] The connection structure 3 can be constructed in a variety of ways according to the actual application. For example, in some embodiments, the connection structure 3 includes a connection portion 4, and the connection portion 4, the top cover 2 and the shell body 1 are constructed as a whole, and the connection portion 4 surrounds the top cover area. The top cover 2 is connected to this breakable connection structure 3, which can make the drone more stable and have better waterproof performance during flight. Among them, the connection portion 4 can be in a complete ring shape to surround the top cover area, so that the connection portion 4 can be broken under the impact of the parachute opening process, so that the top cover 2 is separated from the shell body 1, or the connection portion 4 can be in a ring shape with a fracture to surround the top cover area. For example, the connection portion 4 has a notch in the circumferential direction around the top cover area to facilitate the breakage of the connection portion 4.

[0043] In addition, when the connecting portion 4 has a notch in the circumferential direction around the top cover 2, in order to increase the waterproof effect of the housing, in some specific embodiments, such as Figure 4-Figure 5 As shown, the connection structure 3 may also include a filling portion 5, the connection portion 4 and the filling portion 5 are alternately arranged in the circumferential direction around the top cover area to jointly enclose the top cover area, the connection portion 4, the top cover 2 and the shell body 1 are constructed as a whole, and the filling portion 5 is sealed and filled in the reserved gap (the above-mentioned gap) formed between the connection portion 4, the top cover 2 and the shell body 1. This arrangement can reduce the physical structure between the top cover 2 and the shell body 1, so that the top cover 2 can be easily opened by the parachute module under the premise of being able to resist the vibration energy during the flight of the drone, and the filling portion 5 arranged in the reserved gap can be filled with sealing silicone. The use of sealing silicone can, on the one hand, ensure the sealing of the top cover 2 and make it have a good waterproof function. On the other hand, the elongation at break of the sealing silicone is much greater than the value of the structural member, so the vibration generated by the drone during flight will not destroy the filling portion 5 formed by the sealing silicone.

[0044] In order to further facilitate the top cover 2 to fall off from the shell body 1, the shell has a groove 17 recessed in the shell to form a connecting portion 4 with a thickness less than that of the shell body 1 and the top cover 2, wherein the groove 17 can be arranged in a variety of ways, for example, the groove 17 can be arranged only on the outer wall surface of the shell, or only on the inner wall surface of the shell, or the groove 17 can be arranged on both the outer wall surface and the inner wall surface of the shell, the groove 17 can be arranged continuously or at intervals, and the present disclosure is not limited to this, as long as it can reduce the thickness of at least part of the connecting portion 4. In addition, the cross-section of the groove 17 can be constructed into any shape according to actual usage, for example, a triangle, a rectangle, a semicircle, etc., or as Figure 7 As shown, the structure is a trapezoidal structure, and the chamfer of the trapezoidal groove can be 45°, so that the connecting part 4 can be quickly disconnected.

[0045] According to a second aspect of the present disclosure, a drone is provided, comprising a parachute module and a shell of the above-mentioned drone, wherein the parachute module is located on the inner side of the top cover 2, and the drone has all the beneficial effects of the shell of the above-mentioned drone, which will not be described in detail in the present disclosure.

[0046] Among them, Figure 1-Figure 3 As shown, the parachute module includes a parachute compartment 6 and a parachute that can be stored in the parachute compartment 6, and the parachute compartment 6 has a hatch 7 facing the top cover 2 and for the parachute to detach from the parachute compartment 6; wherein, in order to facilitate the assembly and testing of the parachute module as a whole with the drone, the parachute module also includes a closure 8, which closes the hatch 7 in a closed state and can detach from the hatch 7 in an open state. In addition, in order to prevent the closure 8 and the top cover 2 from becoming falling objects from a high altitude after being detached from the shell body 1 and thus posing a safety hazard, the closure 8 can be connected to the parachute and detachably connected to the top cover 2, so that after the closure 8 and the top cover 2 are detached from the shell body 1, the two will be attached to the parachute and slowly descend to the ground together with the parachute and the drone.

[0047] Alternatively, in some embodiments, the top cover 2 can be directly used to close the hatch 7 in a closed state, and the top cover 2 can be separated from the hatch 7 in an open state, so as to facilitate the lightweight design of the drone.

[0048] Among them, in the embodiment where the parachute module includes a closure 8, the closure 8 can be connected to the parachute compartment 6 by a shear pin. During the parachute opening process, the shear pin will break, so that the closure 8 can be separated from the shell body 1 together with the parachute while ensuring the sealing of the parachute compartment 6; the parachute can be connected to the closure 8 or the top cover 2 by bonding or directly using a draw rope to prevent the closure 8 and the top cover 2 from becoming falling objects from high altitude; the present disclosure is not limited to this.

[0049] In the specific embodiments of the present disclosure, Figure 2-Figure 3 As shown, the top cover 2 is detachably connected to the closure member 8 via a fastener 9; in addition, in order to facilitate the installation of the top cover 2 and the closure member 8, a positioning portion 10 is provided on the top cover 2, and a positioning matching portion 11 matching with the positioning portion 10 is provided on the closure member 8, so that the top cover 2 and the closure member 8 are connected to each other.

[0050] Among them, Figure 6 As shown, a first column 12 is provided on the inner wall surface of the top cover 2, and a first through hole 16 is provided on the first column 12 for connecting the fastener 9 to the closing member 8. When the top cover 2 needs to be connected to the closing member 8, the fastener 9 is at least partially located in the first column 12 and passes through the first through hole 16 to be connected to the closing member 8.

[0051] It should be noted that the fastener 9 can be a bolt, a screw, etc.

[0052] The number of the positioning parts 10 can be multiple and they are arranged circumferentially around the first column 12. The positioning part 10 includes a second column 13 and a positioning groove 14 formed on the second column 13. The positioning groove 14 is plugged into the positioning matching part 11. This can facilitate the positioning connection between the top cover 2 and the closure member 8 on the one hand, and on the other hand, it also improves the stability of the two after the connection.

[0053] In addition, in order to ensure the structural strength of the top cover 2 , reinforcing ribs 15 may be provided between two adjacent second columns 13 and / or between the first column 12 and the second column 13 .

[0054] In summary, when the drone of the present invention is operating normally, the parachute module will be located on the inner side of the shell body 1, that is, inside the drone, and the top cover 2 is in a closed state. When the drone loses control and falls due to an unexpected state, the parachute module will impact the top cover 2. Since the connecting part 4 and the filling part 5 cannot withstand the impact force brought by the parachute module, the connecting part 4 and the filling part 5 will break, causing the top cover 2 to separate from the shell body 1, that is, the top cover 2 is switched from a closed state to an open state, thereby creating an opening on the shell body 1, so that the parachute can pass through the opening and open outside the shell body 1 to slow down the falling speed of the drone. In this process, since the top cover 2 is connected to the parachute through the closing member 8, the top cover 2 will not fly out alone, but will fall to the ground together with the parachute and the drone. Compared with the prior art, the present invention does not need to separately set a parachute module on the outside of the drone, and has a stronger integrity and more aesthetics. In addition, the connection between the top cover 2 and the parachute also avoids the top cover 2 from becoming a high-altitude falling object after the parachute is opened, thereby improving the safety of the drone.

[0055] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0057] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
