Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicles (UAVs), and more particularly to a battery pod and a UAV. Background Technology

[0002] With the widespread application of drones in surveying, logistics, inspection, agriculture and other fields, higher demands are being placed on their endurance and efficiency.

[0003] In related technologies, the ability of drones to operate has been improved by attaching external battery pods to them, but the overall efficiency of drone use still needs to be improved. Utility Model Content

[0004] In view of the above problems, this application provides a battery pod and a drone that can improve the replacement rate of the battery device in the battery pod and improve the utilization efficiency of the drone.

[0005] In a first aspect, this application provides a battery pod, comprising: a housing, including a first wall portion and two second walls portion interconnected with each other, and a cavity enclosed by the first wall portion and the second walls portion, the cavity having a first opening at one end in a first direction, the cavity being used to accommodate a battery device, the first opening and the first wall portion being disposed opposite to each other, the two second walls portion being disposed opposite to each other in a second direction, the first direction and the second direction intersecting; and a conductive mechanism disposed in the housing and located within the cavity, the conductive mechanism being used to electrically connect with the battery device; wherein, in the direction from the first opening to the first wall portion, the minimum distance between the two second walls portion in the second direction tends to decrease.

[0006] In the embodiment of this application, the battery pod includes a housing and a conductive mechanism. The housing includes a first wall and two second walls connected to each other, and a chamber enclosed by the first and second walls for accommodating the battery device. The conductive mechanism is disposed in the chamber. After the battery device is installed in the chamber, it is connected to the conductive mechanism. The two second walls are arranged opposite each other in a second direction. From the first opening to the first wall, the minimum distance between the two second walls in the second direction decreases. Therefore, a larger installation space is formed in the part of the two second walls near the first opening. When installing the battery device into the chamber through the first opening, this larger installation space helps to absorb the assembly error of the battery device, thereby reducing the difficulty of replacing the battery device. This helps to improve the replacement rate of the battery device in the battery pod and improve the utilization efficiency of the UAV.

[0007] In some embodiments, the second wall is inclined toward the cavity in the direction from the first opening to the first wall.

[0008] In the embodiments of this application, by adjusting the minimum distance between the two second walls by tilting the second wall, the thickness of the second wall can be reduced, which helps to achieve a lightweight shell.

[0009] In some embodiments, the battery pod further includes a fixing mechanism, which includes a stop and a latching part. The latching part is disposed on the side of the stop in a third direction. The latching part is connected to the housing and disposed in the cavity. At least two latching parts are disposed opposite to each other. The latching part is used to latch the battery device. The stop is connected to the housing and disposed in the cavity. The side of the stop facing the latching part is used to stop the battery device. The first direction, the second direction and the third direction intersect each other.

[0010] In the embodiment of this application, the battery pod further includes a fixing mechanism, which includes a stop and a latching part. The latching part is disposed on the third-direction side of the stop. The side of the stop facing the latching part is used to stop the battery device to achieve the positioning effect of the battery device and enhance the connection stability between the battery device and the conductive mechanism. At least two latching parts are disposed opposite to each other to latch the battery device to improve the stability of the battery device in the cavity.

[0011] In some embodiments, the stop is movably positioned relative to the housing in a third direction.

[0012] In the embodiment of this application, the stop is movable relative to the housing in a third direction. By adjusting the position of the stop, the position of the battery device in the cavity can be adjusted, so as to facilitate the adjustment of the center of gravity of the battery pod and improve the maneuverability of the drone.

[0013] In some embodiments, a clamping hole is provided through the second wall portion; the fixing mechanism further includes a clamping part, which includes two clamping members disposed opposite to each other in a second direction. Each clamping member includes a rotating end and an abutting end disposed opposite to each other. The rotating end is rotatably disposed relative to the housing in a third direction, and the abutting end is used to press against the battery device in the chamber through the clamping hole.

[0014] In the embodiment of this application, the fixing mechanism further includes a clamping part, which includes two clamping members arranged opposite to each other. The rotating end of the clamping member is rotatably connected to the housing, and the abutting end of the clamping member can clamp the battery device through the clamping hole to improve the stability of the battery device.

[0015] In some embodiments, the housing further includes two fourth walls disposed opposite each other along a third direction, the chamber including second openings at both ends of the third direction, the fourth walls being connected to at least one of the first and second walls and covering a portion of the second opening, the first direction, the second direction and the third direction intersecting each other.

[0016] In the embodiment of this application, the housing further includes two fourth walls, which are arranged opposite each other along a third direction and connected to at least one of the first wall and the second wall. The fourth walls can stop the battery device along the third direction, reducing the risk of the battery device detaching from the chamber under external force. The fourth walls cover part of the second opening, so that the chamber has a larger opening space, making it convenient for users to replace the battery device in the chamber, reducing the difficulty of replacing the battery device, and increasing the replacement rate of the battery device in the battery pod.

[0017] In some embodiments, the fourth wall portion weakens the connection to at least one of the first wall portion and the second wall portion.

[0018] In the embodiment of this application, the fourth wall portion weakens the connection between at least one of the first wall portion and the second wall portion. In the event of thermal runaway of the battery device, the fourth wall portion can be easily removed to facilitate the rapid removal of the battery device from the chamber and reduce the risk of thermal spread of the battery device to the main body of the drone.

[0019] In some embodiments, the battery pod further includes a first adjustment mechanism and a support mechanism. The support mechanism is disposed within the cavity and is used to support the battery device. The first adjustment mechanism is disposed between the support mechanism and the first wall portion and is elastically extendable in a first direction.

[0020] In the embodiment of this application, the first adjustment mechanism is disposed between the support mechanism and the first wall portion. The first adjustment mechanism is elastically extendable in the first direction. The first adjustment mechanism helps to reduce the impact of external force on the battery device and enhance the reliability of the battery pod.

[0021] In some embodiments, the battery pod further includes a first thermal conductive element located within the cavity, the thermal conductivity of the first thermal conductive element being greater than that of the shell.

[0022] In the embodiment of this application, the battery pod further includes a first heat-conducting component located within the cavity. The thermal conductivity of the first heat-conducting component is greater than that of the shell. The first heat-conducting component helps to enhance the heat exchange rate of the battery device, balance the temperature of the battery device, and improve the performance of the battery device.

[0023] In some embodiments, the housing further includes a third wall portion connected to the end of the second wall portion away from the first wall portion. The third wall portion has a smaller dimension in the third direction than the second wall portion in the first direction, so as to partially cover the first opening. The first direction, the second direction, and the third direction intersect each other.

[0024] In the embodiment of this application, the third wall is connected to the end of the second wall away from the first wall to block part of the first opening. The third wall can stop the battery device in the cavity in the first direction and enhance the overall structural strength of the housing. The size of the third wall in the third direction is smaller than the size of the second wall in the first direction to increase the size of the exposed part of the first opening in the second direction, so as to facilitate the replacement of the battery device through the exposed part of the first opening.

[0025] In some embodiments, the third wall portion is used to connect with the drone body, and at least one of the first and second walls portions is provided with a pressure relief hole.

[0026] In the embodiment of this application, at least one of the first wall and the second wall is provided with a pressure relief hole. In the event of thermal runaway of the battery device, high-temperature substances are ejected to the outside of the shell through the pressure relief hole, reducing the risk of thermal spread of the battery device and the risk of the battery device damaging the main body of the drone.

[0027] In some embodiments, the third wall portion is used to connect with the main body of the drone. The third wall portion includes a receiving cavity, and the battery pod also includes a control mechanism disposed within the receiving cavity and electrically connected to the conductive mechanism.

[0028] In the embodiment of this application, a control mechanism is provided in the accommodating cavity of the third wall to reduce the length of the connection path between the control mechanism and the main body of the drone. The control mechanism and the conductive mechanism are electrically connected to adjust the state of the battery device and improve the performance of the battery device.

[0029] In some embodiments, the battery pod further includes a second thermal conductive element disposed within the receiving cavity, the thermal conductivity of the second thermal conductive element being greater than that of the housing.

[0030] In the embodiment of this application, the battery pod also includes a second heat-conducting component located within the housing cavity. The thermal conductivity of the second heat-conducting component is greater than that of the housing. The second heat-conducting component helps to enhance the heat exchange rate of the control mechanism and improve the performance of the control mechanism.

[0031] In some embodiments, the battery pod further includes a second adjustment mechanism disposed on the third wall portion and located within the receiving cavity. The second adjustment mechanism is elastically deformable and abuts against the control mechanism.

[0032] In the embodiment of this application, a second adjustment mechanism is provided inside the accommodating cavity. The second adjustment mechanism elastically abuts against the control mechanism, which not only helps to improve the stability of the control mechanism, but also absorbs the size error of control mechanisms of different specifications, thereby enhancing the adaptability of the battery pod.

[0033] Secondly, this application provides a drone, including a drone body, a battery device and a battery pod as described in the first aspect embodiment. The battery device is disposed in a cavity, the drone body and the shell are connected, and a conductive mechanism is electrically connected to the battery device and the drone body.

[0034] In the embodiments of this application, the drone includes a drone body, a battery device, and a battery pod as described in the first aspect embodiment. The battery device is disposed in the cavity. The battery pod includes a third wall, a first wall, and a second wall that are connected to each other. From the third wall to the first wall, the minimum distance between the two second walls gradually decreases in the second direction. This creates a larger installation space in the portion of the two second walls near the third wall. When installing the battery device into the cavity through the opening, this larger installation space helps to absorb assembly errors of the battery device, thereby reducing the difficulty of replacing the battery device. This helps to improve the replacement rate of the battery device in the battery pod and improve the utilization efficiency of the drone.

[0035] In some embodiments, a clamping hole is provided through the second wall portion; the battery pod further includes a clamping part, which includes two clamping members disposed opposite to each other in a second direction. Each clamping member includes a rotating end and an abutting end disposed opposite to each other. The rotating end is rotatably disposed relative to the housing around a third direction. The first direction, the second direction, and the third direction intersect each other. The battery pod is configured to include a clamped state and an unfolded state. In the clamped state, the abutting end abuts against the battery device, and the conductive mechanism and the battery device are connected. In the unfolded state, the abutting end and the battery device are spaced apart, and the conductive mechanism and the battery device are disconnected.

[0036] In the embodiments of this application, when the battery pod is in the clamped state, the clamping part fixes the battery device, and the conductive mechanism and the battery device are connected. When the battery pod is in the unfolded state, and the clamping part and the battery device are spaced apart, the conductive mechanism and the battery device are disconnected from each other. This helps to reduce the risk of damage to the battery device and the conductive mechanism due to misoperation and improves the reliability of the UAV. Attached Figure Description

[0058] With the widespread application of drones in surveying, logistics, inspection, agriculture, and other fields, higher demands are being placed on their endurance and efficiency. One related technology improves drone endurance by attaching external battery pods, but the overall efficiency of drone use still needs further improvement.

[0059] The reason for the above problems is that the battery devices in the battery pod are difficult to replace and the replacement rate is slow, which causes the drone's utilization efficiency to fall short of expectations.

[0060] To address the aforementioned issues, this application provides a battery pod comprising a housing and a conductive mechanism. The housing includes a first wall and two second walls connected to each other, and a chamber enclosed by the first and second walls for accommodating a battery device. The conductive mechanism is disposed within the chamber, and the battery device is connected to the conductive mechanism after being installed in the chamber. The two second walls are arranged opposite each other in a second direction. From the first opening to the first wall, the minimum distance between the two second walls in the second direction decreases, thus creating a larger installation space near the first opening. When installing the battery device into the chamber through the first opening, this larger installation space helps to absorb assembly errors of the battery device, reducing the difficulty of replacing the battery device. This helps to improve the battery replacement rate in the battery pod and enhance the efficiency of the drone.

[0061] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a battery pod provided in one embodiment of this application; Figure 2 This is a side view of a battery pod provided in one embodiment of this application.

[0062] Firstly, such as Figure 1 and Figure 2 As shown, this application provides a battery pod 1, which includes a housing 2 and a conductive mechanism 3. The housing 2 includes a first wall portion 22 and two second walls portion 23 connected to each other, and a cavity 25 enclosed by the first wall portion 22 and the second walls portion 23. The cavity 25 has a first opening 27 at one end in a first direction X. The cavity 25 is used to accommodate a battery device. The first opening 27 and the first wall portion 22 are arranged opposite to each other, and the two second walls portion 23 are arranged opposite to each other in a second direction Y. The first direction X and the second direction Y intersect. The conductive mechanism 3 is disposed in the housing 2 and located in the cavity 25. The conductive mechanism 3 is used to electrically connect with the battery device. In the direction from the first opening 27 to the first wall portion 22, the minimum distance between the two second walls portion 23 in the second direction Y decreases.

[0063] In the embodiment of this application, the battery pod 1 includes a housing 2 and a conductive mechanism 3. The housing 2 includes a first wall portion 22 and two second walls portion 23 connected to each other, and a chamber 25 enclosed by the first wall portion 22 and the second wall portion 23 for accommodating the battery device. The conductive mechanism 3 is disposed in the chamber 25. After the battery device is installed in the chamber 25, it is connected to the conductive mechanism 3. The two second walls portion 23 are arranged opposite each other in the second direction Y. In the direction from the first opening 27 to the first wall portion 22, the minimum distance between the two second walls portion 23 in the second direction Y tends to decrease. Therefore, a larger installation space is formed in the part of the two second walls portion 23 near the first opening 27. When the battery device is installed into the chamber 25 through the first opening 27, this larger installation space helps to absorb the assembly error of the battery device, thereby reducing the difficulty of replacing the battery device. This helps to improve the replacement rate of the battery device in the battery pod 1 and improve the utilization efficiency of the UAV.

[0064] Optionally, at least one of the first wall portion 22 and the second wall portion 23 may be a honeycomb panel or an aluminum alloy composite panel, which helps to enhance the structural strength of the housing 2 and reduce its weight. For example, the aluminum alloy composite panel may be composed of carbon fiber or glass fiber layers combined with an aluminum alloy skeleton.

[0065] Optionally, the first wall portion 22 and the second wall portion 23 are integrally formed to improve the structural strength of the shell 2; or the first wall portion 22 and the second wall portion 23 are formed separately and fixed together by means of bonding, welding or fusion.

[0066] Optionally, the housing 2 also includes a third wall portion 21, which is connected to the end of the second wall portion 23 away from the first wall portion 22. The third wall portion 21 has a smaller dimension in the third direction Z than the second wall portion 23 in the first direction X, so as to partially cover the first opening 27. The first direction X, the second direction Y, and the third direction Z intersect each other. The third wall portion 21 can, on the one hand, stop the battery device in the chamber 25 in the first direction X, and on the other hand, enhance the overall structural strength of the housing 2. The third wall portion 21 has a smaller dimension in the third direction Z than the second wall portion 23 in the first direction X, so as to increase the size of the exposed portion of the first opening 27 in the second direction Y, making it convenient to replace the battery device through the exposed portion of the first opening 27.

[0067] For example, the first direction X is the height direction of the battery pod 1, the second direction Y is either the length direction or the width direction of the battery pod 1, and the third direction Z is either the length direction or the width direction of the battery pod 1.

[0068] Optionally, the first opening 27 is exposed at one or both ends of the third wall portion 21 in the third direction Z.

[0069] Optionally, the third wall portion 21 can be a honeycomb panel or an aluminum alloy composite panel.

[0070] Optionally, the housing 2 also includes two fourth wall portions 24, which are arranged opposite each other in the third direction Z. The fourth wall portions 24 are connected to at least one of the first wall portion 22 and the second wall portion 23. The fourth wall portions 24 are used to stop the battery device in the third direction Z, reducing the risk of the battery device detaching from the chamber 25 under the action of external force.

[0071] Optionally, the chamber 25 includes second openings at both ends in the third direction Z. The fourth wall portion 24 has a smaller dimension in the first direction X than the second wall portion 23 in the first direction X. The fourth wall portion 24 is connected to at least one of the first wall portion 22 and the second wall portion 23. The fourth wall portion 24 can cover part of the second opening, so that the chamber 25 has a larger opening space, which facilitates the user to replace the battery device in the chamber 25, reduces the difficulty of replacing the battery device, and increases the replacement rate of the battery device in the battery pod 1.

[0072] For example, if the fourth wall portion 24 is disposed at the end of the second wall portion 23 near the first wall portion 22, then the first opening and the second opening are connected to each other to form a larger operating space, which facilitates the replacement of the battery device.

[0073] Optionally, the fourth wall portion 24 weakens its connection to at least one of the first wall portion 22 and the second wall portion 23, allowing for easy removal of the fourth wall portion 24 in the event of thermal runaway of the battery device. This facilitates the rapid detachment of the battery device from the chamber 25 and reduces the risk of heat propagation from the battery device to the main body of the drone. For example, in the event of thermal runaway of the battery device, the fourth wall portion 24 can be pulled off or pried off, and then the battery device can be pulled out of the chamber 25.

[0074] For example, if the fourth wall portion 24 is weakly connected to the first wall portion 22, then the connection strength between the fourth wall portion 24 and the first wall portion 22 is less than the connection strength between the first wall portion 22 and the second wall portion 23. For example, a groove or multiple weakened through holes are provided at intervals at the connection between the fourth wall portion 24 and the first wall portion 22. The same applies to the weakened connection between the fourth wall portion 24 and the second wall portion 23, and will not be described further here.

[0075] Optionally, the battery pod 1 also includes a protective cover, which is a removable cover and is located at the first and second openings of the chamber 25. The protective cover can prevent external impurities from entering the chamber 25 and reduce the risk of misoperation.

[0076] Optionally, the battery pod 1 also includes a first heat-conducting element (not shown in the figure). The first heat-conducting element is located inside the chamber 25. The thermal conductivity of the first heat-conducting element is greater than that of the shell 2. The first heat-conducting element helps to enhance the heat exchange rate of the battery device, balance the temperature of the battery device, and improve the performance of the battery device.

[0077] For example, the first thermal conductive element can be a silicone thermal pad, a copper alloy sheet, or a carbon fiber thermal conductive element, etc.

[0078] For example, the first thermally conductive element is attached to the inner surface of the chamber 25.

[0079] Optionally, the conductive mechanism 3 includes a plurality of contacts disposed on at least one of the third wall portion 21 and the second wall portion 23, the contacts being electrically connected to the battery device. For example, the plurality of contacts may be high-current main power contacts and low-current communication contacts. For example, the contacts are made of silver-plated copper alloy or gold-plated copper alloy. For example, the contacts can be elastically abutted against the battery device to improve the contact reliability between the two. Optionally, the conductive mechanism 3 also includes an overcurrent circuit breaker and a PTC thermal protection element, etc., to improve the reliability of the conductive mechanism 3.

[0080] In the direction from the first opening 27 to the first wall portion 22, the minimum distance between the two second walls 23 in the second direction Y tends to decrease. This creates a larger operating space in the portion of the two second walls 23 near the first opening 27, which can absorb assembly or alignment errors of the battery device. After the battery device enters the chamber 25 through the first opening 27, as the battery device moves toward the first wall portion 22, the minimum distance between the two second walls 23 in the second direction Y gradually decreases to limit the battery device to the expected position.

[0081] The minimum distance between the two second wall portions 23 in the second direction Y refers to the distance between the two second wall portions 23 on one side of the chamber 25 in the second direction Y.

[0082] Optionally, the second wall portion 23 is provided with a scale mark extending in the first direction X on the side facing the chamber 25, and the position of the battery device relative to the chamber 25 in the first direction X is identified by the scale mark.

[0083] Optionally, the thickness of the second wall portion 23 gradually increases in the direction from the first opening 27 to the first wall portion 22. Adjusting the thickness of the second wall portion 23 can adjust the minimum distance between the two second wall portions 23, which helps to enhance the structural strength of the housing 2.

[0084] Optionally, the second wall portion 23 is inclined toward the cavity 25 in the direction from the first opening 27 to the first wall portion 22. By adjusting the minimum distance between the two second wall portions 23 by the inclined second wall portion 23, the thickness of the second wall portion 23 can be reduced, which helps to achieve the weight reduction of the housing 2.

[0085] In some embodiments, such as Figure 1 and Figure 2As shown, the battery pod 1 also includes a fixing mechanism 4, which includes a stop part 41 and a latching part 42. The latching part 42 is disposed on the side of the stop part 41 in the third direction Z. The latching part 42 is connected to the housing 2 and disposed in the chamber 25. At least two latching parts 42 are disposed opposite each other. The latching part 42 is used to latch the battery device. The stop part 41 is connected to the housing 2 and disposed in the chamber 25. The side of the stop part 41 facing the latching part 42 is used to stop the battery device. The first direction X, the second direction Y and the third direction Z intersect each other.

[0086] In these embodiments, the battery pod 1 further includes a fixing mechanism 4, which includes a stop 41 and a latching part 42. The latching part 42 is disposed on the Z-direction side of the stop 41. The side of the stop 41 facing the latching part 42 is used to stop the battery device to achieve the positioning effect of the battery device and enhance the connection stability between the battery device and the conductive mechanism 3. At least two latching parts 42 are disposed opposite to each other to latch the battery device to improve the stability of the battery device in the chamber 25.

[0087] Optionally, at least two latching portions 42 are disposed opposite each other along a first direction X, and / or at least two latching portions 42 are disposed opposite each other along a second direction Y, so that after the battery device is installed into the cavity 25 along a third direction Z, the latching portions 42 are latched onto the periphery of the battery device. For example, the latching portions 42 are in the shape of protrusions.

[0088] Optionally, one end of the stop part 41 is connected to the housing 2, and the other end extends into the chamber 25. After the battery device is installed into the chamber 25, the stop part 41 stops the battery device along the third direction Z on the side facing the snap-fit ​​part 42. When the stop part 41 stops the battery device, the snap-fit ​​part 42 snaps the battery device.

[0089] Optionally, when the battery device abuts against the stop portion 41 in the third direction Z, the contacts of the battery device and the conductive mechanism 3 make contact.

[0090] For example, the fixing mechanism 4 is made of an insulating and flame-retardant material.

[0091] Optionally, the stop part 41 is movable relative to the housing 2 in the third direction Z. By adjusting the position of the stop part 41, the position of the battery device in the chamber 25 can be adjusted, so as to facilitate the adjustment of the center of gravity position of the battery pod 1 and improve the maneuverability of the drone.

[0092] For example, the first wall portion 22 or the second wall portion 23 is provided with an adjustment hole extending in the third direction Z. A portion of the stop portion 41 extends out of the chamber 25 through the adjustment hole. The stop portion 41 is movable relative to the adjustment hole in the third direction Z. The portion of the stop portion 41 extending out of the chamber 25 is fixed to the housing 2 by a nut. When it is necessary to adjust the position of the stop portion 41, the position of the stop portion 41 can be adjusted in the third direction Z by loosening the nut.

[0093] When installing battery devices of different specifications in the chamber 25, the center of gravity of the battery pod 1 will shift due to the change in the size and weight of the battery devices. At this time, the position of the stop part 41 can be adjusted to adjust the position of the battery device in the chamber 25, thereby adjusting the center of gravity of the battery pod 1.

[0094] Optionally, the latching part 42 and the stop part 41 are connected to each other. The latching part 42 is movable relative to the housing 2 in the third direction Z. During the movement of the stop part 41, the latching part 42 moves synchronously.

[0095] Optionally, the contact area of ​​the conductive mechanism 3 is larger than that of the battery device, so that the conductive mechanism 3 can still be connected to the battery device after the battery device position changes; or the conductive part and the stop part 41 are connected, and the conductive part is movable relative to the housing 2 in the third direction Z. During the movement of the stop part 41, the locking part 42 moves synchronously to enhance the connection reliability between the conductive mechanism 3 and the battery device.

[0096] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a battery pod provided in another embodiment of this application.

[0097] In some embodiments, such as Figure 2 and Figure 3 As shown, the second wall portion 23 is provided with a clamping hole 231; the fixing mechanism 4 also includes a clamping portion 43, which includes two clamping members 431 arranged opposite each other in the second direction Y. The clamping member 431 includes a rotating end 4311 and an abutting end 4312 arranged opposite each other. The rotating end 4311 is rotatably arranged relative to the housing 2 around the third direction Z. The abutting end 4312 is used to press against the battery device in the chamber 25 through the clamping hole 231.

[0098] In these embodiments, the fixing mechanism 4 further includes a clamping part 43, which includes two clamping members 431 disposed opposite to each other. The rotating end 4311 of the clamping member 431 is rotatably connected to the housing 2. The abutting end 4312 of the clamping member 431 can clamp the battery device through the clamping hole 231 to improve the stability of the battery device.

[0099] Optionally, if the clamping hole 231 is continuously extended along the third direction Z, then when the battery device moves in the third direction Z to adjust the center of gravity of the battery pod 1, or when different sized battery devices are installed in the chamber 25 in the third direction Z, the clamping part 43 can still clamp the battery device through the clamping hole 231.

[0100] Optionally, the clamping part 43 further includes a limiting member, a trigger member, and an elastic member. The clamping member 431 is connected to the housing 2 via the elastic member, and the trigger member is connected to the limiting member. The limiting member is used to stop the clamping member 431. Before the battery device is installed in the chamber 25, the limiting member stops the clamping member 431 from rotating toward the clamping hole 231, and the elastic member is in a compressed or stretched state. After the battery device is installed in the chamber 25, the user presses the trigger member, which causes displacement or deformation to disengage the limiting member and the clamping member 431. The limiting member no longer stops the clamping member 431, and under the action of the elastic member, the clamping member 431 rotates relative to the housing 2 toward the clamping hole 231. The clamping ends of the two clamping members 431 abut against the battery device, and the clamping part 43 clamps the battery device. For example, the elastic member is a spring, torsion spring, or rubber band, etc.

[0101] Optionally, the clamping member 431 is made of an insulating material to improve the insulation performance of the battery device and the clamping part 43.

[0104] In these embodiments, at least one of the first wall portion 22 and the second wall portion 23 is provided with a pressure relief hole 26. In the event of thermal runaway of the battery device, high-temperature substances are ejected to the outside of the housing 2 through the pressure relief hole, reducing the risk of thermal spread of the battery device and the risk of the battery device damaging the main body of the drone.

[0105] Optionally, the first wall portion 22 or the second wall portion 23 is provided with multiple pressure relief ports at intervals to release the pressure in the chamber 25 more quickly.

[0108] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the battery pod 1 also includes a first adjustment mechanism 5 and a support mechanism 6. The support mechanism 6 is disposed in the chamber 25 and is used to support the battery device. The first adjustment mechanism 5 is disposed between the support mechanism 6 and the first wall portion 22. The first adjustment mechanism 5 is elastically extendable in the first direction X.

[0109] In these embodiments, the first adjustment mechanism 5 is disposed between the support mechanism 6 and the first wall portion 22. The first adjustment mechanism 5 is elastically telescopic in the first direction X.

The third wall portion 21 includes a receiving cavity 211. The battery pod 1 also includes a control mechanism 7, which is disposed in the receiving cavity 211 and electrically connected to the conductive mechanism 3.

[0115] In these embodiments, a control mechanism 7 is provided in the receiving cavity 211 of the third wall portion 21 to reduce the length of the connection path between the control mechanism 7 and the drone body. The control mechanism 7 is electrically connected to the conductive mechanism 3 to adjust the state of the battery device and improve the performance of the battery device.

[0116] Optionally, the control mechanism 7 can be a BMS (Battery Management System). The BMS is used to monitor and balance the state of the battery device, and to provide overcurrent / overtemperature protection and precharge management.

[0117] Optionally, the battery pod 1 also includes a second heat-conducting element, which is disposed in the receiving cavity 211. The thermal conductivity of the second heat-conducting element is greater than that of the housing 2. The second heat-conducting element helps to enhance the heat exchange rate of the control mechanism 7 and improve the performance of the control mechanism 7.

[0118] Optionally, a second heat-conducting element is disposed on the inner wall of the receiving cavity 211, which helps the second heat-conducting element to exchange heat between the housing 2 and the control mechanism 7.

[0119] Optionally, the second heat-conducting component can be a silicone thermal pad, a copper alloy heat exchanger, or a PCM (Phase Change Material) heat exchanger, etc.

[0120] Please see Figure 7 , Figure 7 A partial structural schematic diagram of a battery pod provided in one embodiment of this application.

[0121] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, the battery pod 1 also includes a second adjustment mechanism 8, which is disposed on the third wall portion 21 and located within the receiving cavity 211. The second adjustment mechanism 8 is elastically deformable and abuts against the control mechanism 7.

[0122] In these embodiments, a second adjustment mechanism 8 is provided in the receiving cavity 211. The second adjustment mechanism 8 elastically abuts against the control mechanism 7, which not only helps to improve the stability of the control mechanism 7, but also absorbs the size error of control mechanisms 7 of different specifications, thereby enhancing the adaptability of the battery pod 1.

[0123] Optionally, the second adjusting mechanism 8 is elastically deformable along the first direction X and abuts against the control mechanism 7. The second adjusting mechanism 8 is used to fix the control mechanism 7 in the first direction X and to absorb the size of control mechanisms 7 of different specifications in the first direction X; the second adjusting mechanism 8 is elastically deformable along the second direction Y and abuts against the control mechanism 7. The second adjusting mechanism 8 is used to fix the control mechanism 7 in the second direction Y and to absorb the size of control mechanisms 7 of different specifications in the second direction Y; the second adjusting mechanism 8 is elastically deformable along the third direction Z and abuts against the control mechanism 7. The second adjusting mechanism 8 is used to fix the control mechanism 7 in the third direction Z and to absorb the size of control mechanisms 7 of different specifications in the third direction.

[0124] Optionally, the second adjustment mechanism 8 achieves the effect of elastic deformation through springs or elastic blocks.

Figure 1 and Figure 2 As shown, the battery device is located inside the chamber 25, the drone body and the shell 2 are connected, and the conductive mechanism 3 is electrically connected to the battery device and the drone body.

[0126] In the embodiments of this application, the drone includes a drone body, a battery device, and a battery pod 1 as described in the first aspect embodiment. The battery device is disposed within a chamber 25. The battery pod 1 includes a third wall portion 21, a first wall portion 22, and a second wall portion 23 that are connected to each other. From the third wall portion 21 to the first wall portion 22, the minimum distance between the two second wall portions 23 gradually decreases in the second direction Y. This results in a larger installation space being formed in the portion of the two second wall portions 23 near the third wall portion 21. When installing the battery device into the chamber 25 through the opening, this larger installation space helps to absorb assembly errors of the battery device, thereby reducing the difficulty of replacing the battery device. This helps to improve the replacement rate of the battery device in the battery pod 1 and improve the utilization efficiency of the drone.

[0127] Optionally, the battery device may include one or more battery cells.

[0128] Optionally, the battery pod 1 and the drone body can be detachably connected to facilitate the maintenance and replacement of the battery pod 1.

[0129] Optionally, the battery pod 1 is configured to include a clamped state and an unfolded state. In the clamped state, the abutment end 4312 presses against the battery device, and the conductive mechanism 3 and the battery device are connected. In the unfolded state, the abutment end 4312 and the battery device are spaced apart, and the conductive mechanism 3 and the battery device are disconnected. When the battery pod 1 is in the clamped state, the clamping part 43 fixes the battery device, and the conductive mechanism 3 and the battery device are connected. When the battery pod 1 is in the unfolded state, and the clamping part 43 and the battery device are spaced apart, the conductive mechanism 3 and the battery device are disconnected. This helps to reduce the risk of damage to the battery device and the conductive mechanism 3 due to misoperation and improves the reliability of the UAV.

[0130] In some embodiments, such as Figures 1 to 7As shown, the battery pod 1 includes a housing 2, a conductive mechanism 3, a fixing mechanism 4, a first adjusting mechanism 5, a supporting mechanism 6, and a control mechanism 7. The housing 2 includes a first wall portion 22, two second walls portion 23, and a third wall portion 21 connected to each other, and a chamber 25 enclosed by the first wall portion 22, the second wall portion 23, and the third wall portion 21. The chamber 25 is used to accommodate the battery device. The chamber has a first opening at one end in a first direction. The third wall portion 21 and the first wall portion 22 are arranged opposite each other in the first direction X, and the two second walls portion 23 are arranged opposite each other in the second direction Y. The third wall portion 21 is connected to the second wall portion 23 away from the first wall portion 22. At one end of the first wall portion 22, the third wall portion 21 has a smaller dimension in the third direction Z than the second wall portion 23 in the first direction X, so as to partially block the first opening 27. The first direction X, the second direction Y, and the third direction Z intersect each other. The conductive mechanism 3 is disposed in the housing 2 and located in the cavity 25. The conductive mechanism 3 is used for electrical connection with the battery device. In the direction from the first opening 27 to the first wall portion 22, the second wall portion 23 is inclined towards the cavity 25. The minimum distance between the two second wall portions 23 in the second direction Y gradually decreases. The fixing mechanism 4 includes a stop portion 41, a snap-fit ​​portion 42, and a clamping portion. 43. A snap-fit ​​portion 42 is disposed on the side of the stop portion 41 in the third direction Z. Both the snap-fit ​​portion 42 and the stop portion 41 are disposed within the chamber 25. At least two snap-fit ​​portions 42 are disposed opposite each other. The snap-fit ​​portion 42 is used to snap the battery device. The stop portion 41 is connected to the wall panel and disposed within the chamber 25. The side of the stop portion 41 facing the snap-fit ​​portion 42 is used to stop the battery device. The stop portion 41 is movable relative to the housing 2 in the third direction Z. A clamping hole 231 is provided through the second wall portion 23. The fixing mechanism 4 also includes a clamping portion 43, which includes two clamping members 43 disposed opposite each other in the second direction Y. 1. The clamping member 431 includes a rotating end 4311 and an abutting end 4312 disposed opposite to each other.

The abutting end 4312 is used to press against the battery device in the chamber 25 through the clamping hole 231. The supporting mechanism 6 is disposed in the chamber 25 and is used to support the battery device. The first adjusting mechanism 5 is disposed between the supporting mechanism 6 and the first wall portion 22. The first adjusting mechanism 5 is elastically telescopic in the first direction X. The third wall portion 21 includes a receiving cavity 211. The control mechanism 7 is disposed in the receiving cavity 211 and is electrically connected to the conductive mechanism 3.

[0131] In these embodiments, the battery pod 1 includes a housing 2 and a conductive mechanism 3. The housing 2 includes a first wall portion 22 and two second walls portion 23 connected to each other, and a chamber 25 enclosed by the first wall portion 22 and the second wall portion 23 for accommodating the battery device. The conductive mechanism 3 is disposed in the chamber 25. After the battery device is installed in the chamber 25, it is connected to the conductive mechanism 3. The two second walls portion 23 are arranged opposite each other in the second direction Y. In the direction from the first opening 27 to the first wall portion 22, the minimum distance between the two second walls portion 23 in the second direction Y tends to decrease. Therefore, a larger installation space is formed in the part of the two second walls portion 23 near the first opening 27. When the battery device is installed into the chamber 25 through the first opening 27, this larger installation space helps to absorb the assembly error of the battery device, thereby reducing the difficulty of replacing the battery device. This helps to improve the replacement rate of the battery device in the battery pod 1 and improve the utilization efficiency of the UAV.
