[0044] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 14 , the drone in this embodiment includes components such as a drive module 100, a gas cylinder 220, and an air outlet pipe 300. The gas cylinder 220 is filled with compressed gas, and the compressed gas is high-pressure gas. One end of the air outlet pipe 300 is connected to the drive module 100, and the other end is connected to the launch head 400. A capture net 500 is fixed on the launch head 400. One end of the drive module 100 is connected to the gas cylinder 220, and the other end is connected to the air outlet pipe 300. Components such as the drive module 100 and the air outlet pipe 300 are located in the installation bin 600, and the installation bin 600 is mounted on the main structure of the drone. Through the drive module 100, the compressed gas at high pressure in the gas cylinder 220 can be ejected through the air outlet pipe 300 onto the launch head 400, so as to project the launch head 400 and the capture net 500. The drone in this embodiment can not only project the capture net, but also has a relatively simple structure for the projection part and fewer components, which can reduce the weight and cost to a certain extent.

[0045] Referring to Figures 2 to 4, in some embodiments, the interior of the air outlet pipe 300 is hollow to form an air outlet channel 310. The emitter head 400 is sleeved with the air outlet pipe 300. Here, the sleeve connection means that one of them extends into the interior of the other. A fixing elastic piece 440 is provided on one of them, and a clamping groove 320 is provided on the other. The fixing elastic piece 440 abuts against the clamping groove 320 to fix the emitter head 400 and the air outlet pipe 300. Compressed gas can be ejected onto the emitter head 400 through the air outlet channel 310. Under the action of the ejection force, the fixing elastic piece 440 is separated from the clamping groove 320, and the emitter head 400 is projected. The above fixing structure is relatively simple. During loading, only one of the emitter head 400 and the air outlet pipe 300 needs to be inserted into the other, and the fixing elastic piece 440 is snapped into the clamping groove 320, which is very convenient and fast to operate; during unloading, only compressed gas needs to be provided to separate the emitter head 400 from the air outlet pipe 300, and the difficulty is also relatively low.

[0046] In some embodiments, the installation bin 600 includes a hatch 610 and a bin body 620. The hatch 610 is rotatably connected to the bin body 620, and a hatch elastic member 630 is provided at the connection. The hatch elastic member 630 can be a torsion spring. The emitter head 400 and the air outlet pipe 300 are located inside the bin body 620. Under the drive of the hatch elastic member 630, the hatch 610 remains in the closed state. When compressed gas is ejected onto the emitter head 400 through the air outlet channel 310 and the emitter head 400 is launched, the emitter head 400 hits the hatch 610 and opens it. At this time, the hatch elastic member 630 is deformed. After the emitter head 400 flies out, under the drive of the hatch elastic member 630, the hatch 610 closes again. In this embodiment, there is no need to set up a special opening structure to open the hatch 610 before the emitter head 400 is projected. The hatch 610 is directly opened by the impact of the emitter head 400, and the structure is simpler.

[0047] Referring to Figure 3 , Figures 5 to 7 , in some embodiments, an annular emitter head receiving cavity 450 is defined inside the emitter head 400, and the air outlet pipe 300 extends into the emitter head receiving cavity 450. The annular emitter head receiving cavity 450 has a good limiting effect. After the air outlet pipe 300 extends in, its inner and outer side walls are both abutted, and it is not easy to shift in position. Alternatively, an annular receiving cavity can also be provided on the air outlet pipe 300, and the emitter head 400 extends into the receiving cavity on the air outlet pipe 300.

[0048] In some embodiments, a clamping groove 320 is provided on the air outlet pipe 300, and a fixing elastic piece 440 is provided on the emitter head 400. Alternatively, the clamping groove can also be provided on the emitter head 400, and the fixing elastic piece is provided on the air outlet pipe 300.

[0049] In some embodiments, an annular emitter receiving cavity 450 is defined inside the emitter 400. The air outlet pipe 300 extends into the emitter receiving cavity 450, and a clamping groove 320 is provided on the air outlet pipe 300, and a fixing spring piece 440 is provided on the emitter 400. Of course, the four cases mentioned in the above two embodiments can also be randomly combined. For example, an annular receiving cavity is provided on the air outlet pipe 300, the emitter 400 extends into the receiving cavity on the air outlet pipe 300, the clamping groove is provided on the emitter 400, and the fixing spring piece is provided on the air outlet pipe 300.

[0050] In some embodiments, the emitter 400 includes a head end portion 410, a sleeve 420 and a main body pipe 430. The fixing spring piece 440 is located between the head end portion 410 and the sleeve 420. The head end portion 410 is located at the end of the sleeve 420, the main body pipe 430 extends into the sleeve 420, and the above-mentioned annular emitter receiving cavity 450 is defined between the main body pipe 430 and the sleeve 420. After the air outlet pipe 300 extends into the emitter receiving cavity 450, its inner side wall contacts the main body pipe 430, and its outer side wall contacts the sleeve 420, which can achieve a good limiting effect.

[0051] In some embodiments, an annular fixing portion 421 is provided at the end of the sleeve 420, and a first boss 411 and a second boss 412 are sequentially connected at the end of the head end portion 410. Both the fixing spring piece 440 and the fixing portion 421 are sleeved on the first boss 411. The second boss 412 extends into the main body pipe 430 and is fixedly connected to the main body pipe 430, so that the fixing spring piece 440 and the fixing portion 421 are clamped by the head end portion 410 and the main body pipe 430. Since the shape of the entire emitter 400 is irregular, it is not easy to directly integrally form it during manufacturing. According to the above structure for fixing, each component can be separately manufactured and then assembled, reducing the manufacturing difficulty.

[0052] In some embodiments, the second boss 412 is threadedly connected to the main body pipe 430. After long-term use, the elasticity of the fixing spring piece 440 may weaken and the fixing effect may be poor. At this time, just loosen and remove the head end portion 410 from the main body pipe 430, and the fixing spring piece 440 can be replaced, and the operation is very simple. Or, a magnetic layer can be provided at the contact between the second boss 412 and the main body pipe 430, and the two are fixed by magnetic attraction, and the disassembly is also easy to operate. Or, the two can also be fixed by other conventional methods such as snap connection.

[0053] In some embodiments, the fixing elastic piece 440 includes an annular fixing elastic piece limiting portion 441 and a fixing elastic piece abutting portion 442 extending from the fixing elastic piece limiting portion 441. The fixing elastic piece 440 is sleeved on the first boss 411 through the fixing elastic piece limiting portion 441. The fixing elastic piece abutting portion 442 includes a first abutting section 4421 and a second abutting section 4422 which are integrally connected and bent relative to each other. The first abutting section 4421 is connected to the fixing elastic piece limiting portion 441 and bent relative to it. A hole 422 is provided on the sleeve 420. The connection portion of the first abutting section 4421 and the second abutting section 4422 protrudes towards the card slot 320, and after passing through the hole 422, the connection portion abuts against the card slot 320.

[0054] In some embodiments, a plurality of fixing elastic piece abutting portions 442 can be connected around the fixing elastic piece limiting portion 441. Correspondingly, a plurality of holes 422 are provided on the sleeve 420, and a plurality of card slots 320 are provided on the air outlet pipe 300. Each fixing elastic piece abutting portion 442 passes through one hole 422 at the corresponding position and abuts against the corresponding card slot 320 at that place. Through the abutting fixation at multiple positions, the fixing relationship can be made more stable, and when the compressed gas is not ejected, the emitting head 400 is not easily separated from the air outlet pipe 300.

[0055] In some embodiments, the groove wall of the card slot 320 can be rounded to form a relatively smooth curved surface. In this way, when unloading the emitting head 400, the fixing elastic piece 440 is more easily detached from the card slot 320.

[0056] In some embodiments, the main body pipe 430 of the emitting head 400 also has a cavity 431 inside. After installation is completed, the compressed gas can enter the cavity 431 through the air outlet channel 310 to push out the emitting head 400. Although the compressed gas can also be directly ejected onto the emitting head 400 to push it out, when the gas enters its interior to push it out, the position where the gas acts on the emitting head 400 is closer to the position where the fixing elastic piece 440 abuts against the card slot 320, making it easier for the fixing elastic piece 440 to separate from the card slot 320.

[0057] Refer to Figure 7 And Figure 8 , in some embodiments, a fixing ring 423 is provided on the sleeve 420 of the emitting head 400, and the capture net 500 is tied to the fixing ring 423 to achieve fixation. When the emitting head 400 is projected, it will fly out together with the capture net 500.

[0058] In some embodiments, a plurality of emitting heads 400 and air outlet pipes 300 are provided. Each emitting head 400 and an air outlet pipe 300 are connected through the above-mentioned emitting head fixing structure. Different regions of the capture net 500 are respectively fixedly connected to an emitting head 400 to open the capture net 500 so that it can more accurately cover the object to be captured when reaching the target position.

[0059] Reference Figure 9 、 Figure 10 and Figure 14 , in some embodiments, the driving module 100 includes components such as a support 110, a first seal 130, and a first elastic member 140. The support 110 can be integrally formed or composed of multiple components. For example, in this embodiment, the support is formed by sleeving two components, and the two components are threadedly connected. A receiving cavity 120 is defined inside the support 110, and an air inlet 111 and an air outlet 112 are further provided on the support 110. The compressed gas in the gas cylinder 220 can enter the receiving cavity 120 through the air inlet 111 and can be discharged from the receiving cavity 120 through the air outlet 112.

[0060] The first seal 130 and the first elastic member 140 are located inside the receiving cavity 120. The first seal 130 includes a shielding portion 131 and a plug 132, which are respectively located at both ends of the first seal 130. Both ends of the first elastic member 140 abut against the support 110 and the shielding portion 131 respectively. Under the abutting action of the first elastic member 140, the plug 132 will abut against the air outlet 112 to close the air outlet 112. The shapes of the plug 132 and the air outlet 112 are matched so that their fitting degree is higher. For example, both of them are set to be arc-shaped. A silicone layer or a rubber layer can also be provided on the surface of the plug 132 to enhance the sealing performance and reduce the probability of air leakage.

[0061] The air outlet pipe 300 is connected to the air outlet 112 of the support 110. When the first seal 130 moves in the first direction and separates from the air outlet 112, the air outlet 112 is communicated with the air outlet pipe 300, and the compressed gas enters the air outlet pipe 300 through the air outlet 112 and is sprayed onto the emitting head. The components of the driving module 100 in this embodiment are fewer and the structure is relatively simple, which can reduce costs and reduce weight to a certain extent.

[0062] Reference Figures 9 to 11 , in some embodiments, the support 110 is further provided with an air leakage port 113, which is separated from the air inlet 111, and the air leakage port 113 can communicate with the outside. A partition member 160 is further provided inside the receiving cavity 120, and the partition member 160 is connected to the support 110. The partition member 160 is arranged around the shielding portion 131, that is, the shielding portion 131 extends into the partition member 160, and the peripheral surface of the shielding portion 131 abuts against the side wall of the partition member 160. The partition member 160 divides the receiving cavity 120 into two parts. Specifically, a first cavity 121 is formed between the partition member 160 and the support 110, and a second cavity 122 is formed between the partition member 160 and the shielding portion 131. The air inlet 111 and the air outlet 112 are both communicated with the first cavity 121, and the air leakage port 113 is communicated with the second cavity 122.

[0063] The air leakage port 113 is separated from the air inlet 111, which can prevent gas from directly flowing from the air inlet 111 into the air leakage port 113 and being discharged. When the compressed gas fills the first cavity 121, in addition to the first elastic member 140 being oppositely abutted against the plug 132 in the reverse direction of the first direction, the compressed gas will further make the plug 132 tightly abut against the air outlet 112 in the reverse direction of the first direction. Therefore, if a conventional driving method is adopted, such as using a cylinder or a motor to push or pull the first sealing member 130 to move in the first direction, the resistance to movement is relatively large, and a sufficiently large driving force is required to achieve it. In this embodiment, when the compressed gas in the gas cylinder 220 enters the first cavity 121, the air pressure in the first cavity 121 is much higher than the outside. Just by connecting the air leakage port 113 to the outside, the compressed gas in the first cavity 121 will push the first sealing member 130 to move in the first direction, which is easy to implement in operation.

[0064] In some embodiments, the shielding portion 131 abuts against the separating member 160, and a sealing ring is provided between them, but it does not reach a completely sealed state, and there is a gap between them to form a channel. The compressed gas in the first cavity 121 can enter the second cavity 122 through this channel. In this way, the air pressures in the first cavity 121 and the second cavity 122 are approximately equal. When the gas cylinder 220 is connected to the accommodating cavity 120, the compressed gas enters the first cavity 121. Since the air pressures in the first cavity 121 and the second cavity 122 are approximately equal, the compressed gas at high pressure in the first cavity 121 has no tendency to push the shielding portion 131 to move in the first direction. Just by setting a first elastic member 140 with a smaller specification, the plug 132 can be abutted against the air outlet 112 to achieve sealing. If the shielding portion 131 and the separating member 160 are completely sealed, the pressure in the second cavity 122 is normal pressure, and the air pressure in the first cavity 121 is higher than that in the second cavity 122. After the compressed gas enters the first cavity 121, it may push the first sealing member 130 to move in the first direction. In order to prevent this situation from occurring and opening the air outlet 112 in advance, a large-sized spring with a large resilience needs to be set, which may lead to an increase in weight and cost.

[0065] After the air leakage port 113 is connected to the outside, since the air pressure in the second cavity 122 is much higher than the outside atmospheric pressure, the first sealing member 130 will move in the first direction, and the first elastic member 140 is compressed. Although as the compressed gas in the second cavity 122 gradually discharges, the compressed gas in the first cavity 121 will continue to enter the second cavity 122, there is a certain obstacle for the gas to enter the second cavity 122 due to the shielding and blocking of the shielding portion 131 and the separating member 160. After the plug 132 is separated from the air outlet 112, the compressed gas in the first cavity 121 can be directly discharged through the air outlet 112 without being blocked or obstructed by any components. Therefore, most of the gas will be directly discharged through the air outlet 112 to the outlet pipe 300.

[0066] Reference Figures 11 to 13 In some embodiments, a first driving member 150 and a locking member 170 are further included. The air leakage port 113 can be closed by the locking member 170, and the locking member 170 can be driven by the first driving member 150 to move to open the air leakage port 113. For example, the air leakage port 113 can be blocked by a silica gel plug. When the air leakage port 113 needs to be opened, the silica gel plug can be pulled out or pushed out by the first driving member 150.

[0067] In some embodiments, a second elastic member 180 and an abutting member 190 are further included. The area around the air leakage port 113 on the support 110 is hollowed out to form a recess 117. The abutting member 190 extends into the recess 117 and is threadedly connected to the recess 117. A first through hole 191 is provided on the abutting member 190 and its interior is hollow. The first through hole 191 communicates with the air leakage port 113. The locking member 170 is located inside the abutting member 190. The two ends of the second elastic member 180 respectively abut against the bottom wall of the recess 117 and the locking member 170, so that the locking member 170 abuts against the abutting member 190 to close the first through hole 191. When it is necessary to communicate the air leakage port 113 with the outside, the locking member 170 is driven by the first driving member 150 to move so that it separates from the abutting member 190 and no longer blocks the first through hole 191. Here, the second elastic member 180 is in a compressed state. When it is necessary to close the air leakage port 113, the first driving member 150 stops working. Under the action of the resilience of the second elastic member 180, the locking member 170 will automatically reset without manually inserting it into the first through hole 191, which is more convenient to operate.

[0068] In some embodiments, the locking member 170 includes a main body portion 171 and a trigger portion 172. The trigger portion 172 extends into the first through hole 191, and the main body portion 171 extends out of the abutting member 190 through the first through hole 191. The trigger portion 172 has an inclined surface 1721. The second elastic member 180 abuts against the end of the trigger portion 172 so that the inclined surface 1721 abuts against the hole wall of the first through hole 191 to block the first through hole 191. The abutting by the inclined surface can improve the fitting degree. The first driving member 150 is located on one side of the main body portion 171. The first driving arm 151 can rotate to push the main body portion 171 in a direction away from the abutting member 190, so that the trigger portion 172 separates from the first through hole 191. A servo motor can be used as the first driving member 150 to reduce the weight, and the first driving arm 151 is a servo arm. The trigger portion 172 is made of a silica gel member or a rubber member to improve the sealing performance. Alternatively, a sealing block 1140 can be further provided. A through hole is also provided on the sealing block 1140. The through hole is coaxial with and communicates with the first through hole 191. The main body portion 171 passes through the through hole on the sealing block 1140 and then extends out of the first through hole 191. The inclined surface 1721 abuts against the hole wall of the sealing block 1140. By providing the sealing block 1140, the sealing performance can be improved and air leakage is not likely to occur.

[0069] ReferenceFigures 14 to 16 In some embodiments, the gas cylinder 220 is placed inside the gas cylinder housing 210. A puncturing member 115 is provided on the support 110, and a sharp needle-like object can be selected as the puncturing member 115. When the gas cylinder housing 210 is connected to the support 110, the puncturing member 115 will puncture the seal of the gas cylinder 220, enabling the gas cylinder 220 to communicate with the air inlet 111. In this embodiment, the gas cylinder 220 automatically opens the air inlet while being installed on the support 110, eliminating the need to open it in advance and then install it, thus avoiding gas loss and waste.

[0070] In some embodiments, the support 110 is provided with an outwardly extending portion 116. The extending portion 116 is arranged around the air inlet 111, and the puncturing member 115 is arranged inside the extending portion 116. A ring-shaped blocking member 1120 is fixedly embedded on the inner side wall of the extending portion 116. The end of the second sealing member 1110 is provided with a blocking surface 1112. For example, the end of the second sealing member 1110 can be hollowed out radially in a circle to form the blocking surface 1112. A second sealing member 1110 is arranged inside the extending portion 116. A third elastic member 1100 is placed inside the second sealing member 1110 and sleeved outside the puncturing member 115. The two ends of the third elastic member 1100 respectively abut against the bottom wall of the extending portion 116 and the second sealing member 1110. Under the resilience of the third elastic member 1100, the blocking surface 1112 abuts against the blocking member 1120 for limiting, preventing the second sealing member 1110 from coming out. The gas cylinder housing 210 can be sleeved outside the extending portion 116 and is threadedly connected to the extending portion 116. When the extending portion 116 is screwed into the gas cylinder housing 210, the end of the gas cylinder 220 will abut against the second sealing member 1110, causing it to move in the direction close to the support 110. The end of the second sealing member 1110 is provided with a second through hole 1111. When the second sealing member 1110 moves to a predetermined position, the puncturing member 115 will pass through the second through hole 1111 and be exposed, coming into contact with the end seal of the gas cylinder 220 and puncturing the seal. At this time, the third elastic member 1100 is in a compressed state. When the gas cylinder housing 210 is separated from the extending portion 116, under the resilience of the third elastic member 1100, the second sealing member 1110 resets, and the blocking surface 1112 abuts against the blocking member 1120 again. In this embodiment, the extending portion 116 can shield and protect the puncturing member 115, preventing the puncturing member 115 from being directly exposed and damaged by knocking when the gas cylinder 220 is not yet installed, and also preventing the operator from being stabbed.

[0071] Refer to Figures 9 to 11, in some embodiments, a guiding member 1130 is further provided. One end of the guiding member 1130 is connected to the support 110, and the first elastic member 140 is sleeved on the guiding member 1130. A guiding cavity 133 is provided inside the first seal 130. When the first seal 130 moves, the guiding member 1130 can extend into or out of the guiding cavity 133. By guiding with the guiding member 1130, the movement process of the first seal 130 can be made smoother. A gas release port 114 is further provided on the support 110, and a valve is provided at the gas release port 114. After use, the valve at the gas release port 114 can be opened to discharge the residual gas in the accommodating cavity 120.

[0072] Referring to Figures 17 to 18 , in some embodiments, the driving module further includes a safety member 1150. When the first driving arm 151 rotates to a predetermined position, it will abut against the locking member 170 and push out the locking member 170. The second driving member 1160 includes a second driving arm 1161. The safety member 1150 is fixedly connected to the second driving arm 1161, and the second driving member 1160 drives the safety member 1150 to rotate through the second driving arm 1161. When the safety member 1150 rotates to a predetermined position, it can abut against the first driving arm 151 to block the first driving arm 151 from continuing to rotate, realizing the limit of the first driving arm 151. When it is necessary to trigger the first driving member 150 to drive the locking member 170 to move, the safety member 1150 rotates to separate from the first driving arm 151, and the first driving arm 151 can rotate freely, thereby reducing the probability of mis-triggering of the first driving member 150. The second driving member 1160 can be a servo motor, and the second driving arm 1161 is a servo motor arm.

[0073] In some embodiments, the first driving arm 151 includes a first driving arm main body portion 1511 and a first driving arm abutting portion 1512. The first driving arm abutting portion 1512 extends from the first driving arm main body portion 1511. The first driving arm main body portion 1511 can abut against the locking member 170, and the first driving arm abutting portion 1512 can abut against the safety member 1150. The distance between the first driving arm main body portion 1511 and the locking member 170 is greater than the distance between the first driving arm abutting portion 1512 and the safety member 1150. In this way, during the rotation of the first driving arm 151, before the first driving arm main body portion 1511 abuts against the locking member 170, the safety member 1150 has already abutted against the first driving arm abutting portion 1512, so as to ensure that the first driving arm main body portion 1511 cannot push the locking member 170 to move when the safety member 1150 does not leave this position.

[0074] Specifically, in some embodiments, the safety member 1150 and the locking member 170 are located on the same side of the first driving arm 151. The width of the first driving arm abutting portion 1512 is greater than that of the first driving arm main body portion 1511. Here, the width direction refers to the direction in which the first driving arm main body portion 1511 abuts against the locking member 170 and pushes it out.

[0075] Alternatively, in some embodiments, the safety member 1150 and the locking member 170 are placed in parallel, and extend beyond the end of the locking member 170 to ensure that the distance between the safety member 1150 and the first driving arm abutting portion 1512 is less than the distance between the locking member 170 and the first driving arm main body portion 1511. At this time, there is no limitation on the widths of the first driving arm abutting portion 1512 and the first driving arm main body portion 1511.

[0076] In some embodiments, a limiting block is provided on the safety member 1150, and a limiting groove is provided on the first driving arm 151, and the extending path of the limiting groove partially coincides with the rotating path of the limiting block. In this way, when the safety member 1150 locks or unlocks the first driving arm 151, the limiting block will slide into or out of the limiting groove. Through the cooperation of the limiting block and the limiting groove, the rotation process of the safety member 1150 can be made smoother.

[0077] Similarly, in some embodiments, the positions of the limiting block and the limiting groove can also be swapped. For example, a limiting block is provided on the first driving arm 151, a limiting groove is provided on the safety member 1150, and the limiting groove is arc-shaped.

[0078] In some embodiments, a buffer layer is provided outside the safety member 1150 to protect the safety member 1150 and slow down the wear caused during the process of abutting against the first driving arm 151, thereby extending the service life. The buffer layer can be silicone, rubber, sponge, etc. Similarly, a buffer layer can also be provided on the first driving arm 151.

[0079] Refer to Figure 1 、 Figures 19 to 21, in some embodiments, it further includes a fuselage main body 700 and a shock absorption module 800. The drive module 100 is connected to the fuselage main body 700 through the shock absorption module 800. Among them, the fuselage main body 700 is a mounting gimbal, and the mounting gimbal is connected to the main body structure of the drone. The shock absorption module 800 includes components such as a shock absorption connecting piece 810, a shock absorption sliding piece 820, and a fourth elastic member 830. Here, the shock absorption connecting piece 810 can be the outer shell of the shock absorption module, and the fourth elastic member 830 and the shock absorption sliding piece 820 are sequentially arranged in the outer shell along the reverse direction of the first direction. The shock absorption connecting piece 810 is connected to the fuselage main body 700, and the drive module 100 is connected to the shock absorption sliding piece 820. When the drive module 100 projects the transmitter head along the reverse direction of the first direction, a recoil force along the first direction will be generated on the drive module 100 at the moment of projection, causing the drive module 100 to move along the first direction. When it moves, it will abut against the fourth elastic member 830, causing the fourth elastic member 830 to be compressed, so as to absorb the energy generated by the recoil force, reduce the shaking of the drone caused by the recoil force, and enable the drone to fly in a relatively stable attitude.

[0080] In some embodiments, the shock absorption module 800 further includes a fifth elastic member 840, and the fourth elastic member 830, the shock absorption sliding piece 820, and the fifth elastic member 840 are sequentially arranged along the reverse direction of the first direction. In this way, when the drive module 100 slides in the first direction due to the recoil force, it will compress the fourth elastic member 830 through the shock absorption sliding piece 820. When the fourth elastic member 830 rebounds, the shock absorption sliding piece 820 slides in the reverse direction of the first direction. During this process, the shock absorption sliding piece 820 may slide in front of its initial position. At this time, it can be shock-absorbed by abutting against the fifth elastic member 840 and causing the fifth elastic member 840 to be compressed and deformed, further reducing the shaking of the drone.

[0081] In some embodiments, the shock absorption module 800 further includes a sliding shaft 850, and both the shock absorption sliding piece 820 and the fourth elastic member 830 are sleeved on the sliding shaft 850. The sliding shaft 850 can guide the shock absorption sliding piece 820 and the fourth elastic member 830, making their movement process more stable and not prone to position deviation. When the fifth elastic member 840 is provided, the fifth elastic member 840 is also sleeved on the sliding shaft 850.

[0082] In some embodiments, the shock absorption module 800 further includes a linear bearing 860, and the shock absorption sliding piece 820 is connected to the sliding shaft 850 through the linear bearing. The linear bearing 860 can reduce the resistance when the shock absorption sliding piece 820 slides on the sliding shaft 850 and slow down the wear of the shock absorption sliding piece 820. When the fifth elastic member 840 is provided, both ends of the shock absorption sliding piece 820 are connected to the sliding shaft 850 through the linear bearing 860.

[0083] In some embodiments, the end of the damping sliding member 820 abuts against the fourth elastic member 830. In this way, it can be ensured that there is no gap between the two when no recoil is generated. When the damping sliding member 820 moves due to the recoil, the fourth elastic member 830 can be compressed immediately, and the damping response speed is fast. When the fifth elastic member 840 is provided, the two ends of the damping sliding member 820 abut against the fourth elastic member 830 and the fifth elastic member 840 respectively.

[0084] In some embodiments, the end of the damping sliding member 820 is fixedly connected to the fourth elastic member 830. In this way, the linkage between the two can be better, and the response speed during damping can be further accelerated. When the fifth elastic member 840 is provided, the two ends of the damping sliding member 820 are fixedly connected to the fourth elastic member 830 and the fifth elastic member 840 respectively.

[0085] In some embodiments, the two ends of the fourth elastic member 830 respectively abut against the side wall of the shock-absorbing connector 810 and the shock-absorbing sliding member 820, and the two ends of the fifth elastic member 840 respectively abut against the side wall of the shock-absorbing connector 810 and the shock-absorbing sliding member 820. In this way, there is no need to set up additional components to abut the two elastic members, and the side wall of the shock-absorbing connector 810 can be directly used, which can reduce components and simplify the structure.

[0086] In some embodiments, the shock absorbing module 800 further includes a shock absorbing extension 870, and the shock absorbing extension 870 is fixedly connected to the shock absorbing sliding member 820. The shock absorbing connecting member 810 is provided with a slide groove extending along the first direction, and the end of the shock absorbing extension 870 extends from the slide groove to the outside of the shock absorbing connecting member 810 and is connected to the driving module 100. The width of the slide groove matches the thickness of the shock absorbing extension 870, and the shock absorbing extension 870 can slide synchronously with the shock absorbing sliding member 820. When sliding, the slide groove guides the shock absorbing extension 870, so that its movement is more stable and it is not easy to be offset.

[0087] In some embodiments, multiple shock absorbing modules 800 are provided, and the driving module 100 is connected to the fuselage body 700 through the multiple shock absorbing modules 800. In this way, the shaking caused by the recoil can be shared by the multiple shock absorbing modules, and the shock absorbing effect is better.

[0088] In some embodiments, a pitch driving member 900 is further provided, the driving module 100 is connected to the pitch driving member 900 through the mounting chamber 600, and the pitch driving member 900 is connected to the shock absorbing extension member 870. The pitch driving member 900 can be used to adjust the tilt angle of the mounting chamber 600, the gas cylinder 220 and other components to align with the target position.

[0089] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the relevant art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
