Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle technology, and in particular to a battery compartment locking safety device and a drone. Background Technology

[0002] As a type of flying device with high transportation efficiency and speed, drones have broad application prospects in the fields of delivery and food delivery.

[0003] Existing drones typically have a locking mechanism to secure the battery. However, under extreme conditions (such as extreme overload in the air) or due to accidental human intervention during maintenance, the battery locking mechanism can shift, causing the battery to mislock. Because the battery locking function fails, the drone's battery can easily slide relative to the drone body, leading to a power outage and loss of control. If the drone is in flight at this time, the fallen battery could potentially damage people or objects on the ground. Summary of the Invention

[0004] In view of this, this application provides a battery compartment locking and safety device to solve the problems of insecure fixing and poor safety of drone batteries in the prior art.

[0005] This application provides a battery compartment locking device, including a receiving member, a first locking member, and a second locking member. The receiving member has a receiving portion for receiving a battery, and the battery is slidably mounted in the receiving portion. The first locking member has a locking portion and is slidably disposed on the receiving member. The first locking member is movable between a locked position and an unlocked position. When the first locking member is in the locked position, the locking portion abuts against the battery to restrict the battery's movement. When the first locking member is in the unlocked position, the locking portion disengages from the battery. The second locking member is rotatably disposed on the receiving member and is movable between a first position and a second position. The first locking member has a corner portion at one end near the second locking member, and the second locking member has a limiting portion with an opening. When the second locking member is in the first position, the first locking member is movable between the locked position and the unlocked position, causing the corner portion to pass through the opening. When the second locking member is in the second position, the limiting portion blocks the corner portion to restrict the first locking member's movement between the locked position and the unlocked position.

[0006] In the above solution, the battery compartment locking safety device can be applied to devices with battery replacement functions, such as drones, to improve safety.

[0007] After the battery is slidably installed in the housing, the first locking member is moved from the unlocked position to the locked position, at which point the locking part abuts against the battery to restrict its movement. Subsequently, the second locking member is rotated, moving from the first position to the second position. During this process, the limiting part rotates into the movement path of the corner of the first locking member, thereby restricting the first locking member from moving from the locked position to the unlocked position. In summary, the battery compartment locking device provided in this application, by setting the structural and positional relationship between the first and second locking members, enables the battery compartment locking device to more securely fix the battery, preventing the battery from falling out under extreme conditions and improving the overall safety of the device.

[0008] In one possible design, the limiting portion protrudes from the end of the second locking member, and the sliding direction of the first locking member is perpendicular to the rotation axis of the second locking member.

[0009] In the above solution, the limiting part is located at the end of the second locking member. When the second locking member is rotated, the opening position rotates along with the rotation of the second locking member. At the same time, the limiting part rotates synchronously to the movement path of the corner portion, thereby restricting the first locking member from moving from the locked position to the unlocked position. This arrangement makes the structure of the second locking member more compact, thereby reducing the size of the battery compartment locking device.

[0010] In one possible design, the limiting part is provided with a guide arc surface on the side near the rotation axis of the second locking member, and the portion of the guide arc surface away from the opening is closer to the rotation axis of the second locking member than the portion of the guide arc surface near the opening.

[0011] In the above scheme, a guide arc surface is provided on the side of the limiting part near the rotation axis of the second locking member. During the rotation of the second locking member, the guide arc surface can be used to apply force to the corner part, so as to move the first locking member that has not moved to the position to the locking position, thereby improving the fault tolerance of the battery compartment locking safety device.

[0012] In one possible design, the battery compartment locking device further includes a steering assembly slidably disposed on the receiving member. The sliding direction of the steering assembly is in the same direction as the rotation axis of the second locking member. The steering assembly includes a pressing block and a ramp block connected to each other. The ramp block abuts against the first locking member and is used to drive the first locking member to move in a direction away from the limiting part.

[0013] In the above scheme, the steering component uses the inclined block to push the first locking member to move, thereby changing the transmission trajectory that drives the first locking member to move. In this way, the pressing direction of the rotating component is the same as the rotation axis of the second locking member. This not only saves space in the battery compartment locking device, but also makes the operating surfaces of the first and second locking members on the same plane, improving the ease of operation of the battery compartment locking device.

[0014] In one possible design, the battery compartment locking device further includes a reset elastic element connected to the first locking element, which is used to move the first locking element toward the limiting portion.

[0015] In the above scheme, the reset elastic element enables the first locking element to automatically reset between the unlocked position and the locked position, which simplifies the operation of the battery compartment locking safety device.

[0016] In one possible design, the battery compartment locking device includes two first locking members and one second locking member. The receiving member has two receiving portions, and a partition is formed between the two receiving portions. The second locking member and the first locking member are both disposed on the partition, and the second locking member is located between the two first locking members.

[0017] In the above solution, the battery compartment locking device has two receiving parts on its receiving component, and two first locking components and one second locking component are simultaneously provided. By utilizing the linkage relationship of the above structure, the two batteries can be locked synchronously, making the battery compartment locking device in this application compact in structure and large in carrying capacity.

[0018] In one possible design, the battery compartment locking device further includes a rotation detection component, which includes a signal element disposed on the second locking member and a detection element disposed on the receiving member. The signal element and the detection element are disposed correspondingly, and the detection element is used to identify the rotation angle of the signal element.

[0019] In the above solution, by setting a rotation detection component, the rotation state of the second locking member can be detected in real time. When the second locking member has not rotated to the correct position, a signal can be issued to warn, thereby improving the safety and stability of the battery compartment locking device.

[0020] In one possible design, the signaling element is a magnet, and the detection element is a magnetic field angle sensor.

[0021] In the above scheme, the magnet and the magnetic field angle sensor are set up in combination, which has high sensitivity and good reliability.

[0022] In one possible design, the second locking member further includes a handle that extends to the outer side of the surface of the receiving member.

[0023] In the above scheme, the addition of a handle improves the ease of turning the second locking element.

[0024] In one possible design, the handle has an extension whose projection in the sliding mounting direction of the battery coincides with the battery when the second locking member is in the second position.

[0025] In the above solution, when the second locking member is in the second position, the extension blocks the sliding installation path of the battery. Thus, even if the first locking member and the second locking member fail, the battery will still be blocked by the extension, thereby preventing the battery from coming out under extreme conditions and further improving the safety of the battery compartment locking device.

[0026] This application also provides a drone that includes the battery compartment locking safety device described in any of the above claims, and thus obviously has the advantages of the battery compartment locking safety device described above.

[0061] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0063] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0064] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0065] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0066] The following describes a specific embodiment of the battery compartment locking device provided in the embodiments of this application.

[0067] The battery compartment locking device 100 provided in this application can be applied to devices with battery replacement capabilities, such as delivery drones and food delivery drones. Existing drone technology typically uses a single locking and unlocking structure to secure the battery 110. However, due to the usage scenarios and movement characteristics of drones, there is a high probability that the drone will encounter extreme conditions or have its unlocking button accidentally pressed, causing the battery 110 locking function to fail. In this case, the drone's battery 110 can easily slide relative to the drone body, leading to power loss and loss of control. Especially during drone flight, a slipping battery 110 could potentially cause damage to people or objects on the ground.

[0068] Therefore, designing a battery compartment locking and insurance device 100 that securely fixes the battery 110 and provides good safety, as well as a drone, is a problem that urgently needs to be solved by those skilled in the art.

[0069] Please see Figures 1 to 9 This application provides a battery compartment locking device 100, including a housing 1, a first locking member 2, and a second locking member 3. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The housing 1 is provided with a housing portion 11 for housing the battery 110, and the battery 110 is slidably mounted in the housing portion 11; the first locking member 2 has a locking portion 21, and the first locking member 2 is slidably disposed on the housing 1. The first locking member 2 can move between a locked position and an unlocked position. When the first locking member 2 is in the locked position, the locking portion 21 abuts against the battery 110 to restrict the movement of the battery 110; when the first locking member 2 is in the unlocked position, the locking portion 21 disengages from the battery 110; the second locking member 3 is rotatably disposed on the housing 1, and the second locking member 3 is rotatably disposed on the housing 1. The locking member 3 can move between a first position and a second position. The first locking member 2 has a corner portion 22 at one end near the second locking member 3. The second locking member 3 has a limiting portion 31 with an opening 311. When the second locking member 3 is in the first position, the first locking member 2 can move between the locked position and the unlocked position and drive the corner portion 22 through the opening 311. When the second locking member 3 is in the second position, the limiting portion 31 blocks the corner portion 22 to limit the movement of the first locking member 2 between the locked position and the unlocked position.

[0070] Please see Figure 1 , Figure 2 , Figure 8 and Figure 9The housing 1 can be a frame structure or a box structure. The housing 1 can be installed in the center of the drone to improve its balance. The housing 1 has a housing section 11 for housing the battery 110. The housing section 11 can be a cavity structure or a mounting groove structure with a guide structure. Guide rails can be provided on the housing section 11 to improve the installation accuracy of the battery 110. The battery 110 can be square, cylindrical, or any other arbitrary shape, as long as it can fit into the housing section 11. The battery 110 can be slidably installed in the housing section 11 along the opening 311 direction.

[0071] Please see Figure 2 , Figure 3 and Figure 4 The first locking member 2 can be a strip-shaped structure with a locking part 21. In some embodiments, the locking part 21 can be located on the side of the first locking member 2 near the battery 110, and the side of the battery 110 can have a protruding boss structure to facilitate contact between the locking part 21 and the boss. The first locking member 2 is slidably disposed on the receiving member 1 and can move between a locked position and an unlocked position. In some embodiments, the first locking member 2 has a portion protruding from the receiving member 1 to facilitate operation by an operator. When the first locking member 2 is in the locked position, the locking part 21 abuts against the battery 110 to restrict the battery 110 from moving in the direction of disengaging from the receiving member 11; when the first locking member 2 is in the unlocked position, the locking part 21 disengages from the battery 110, at which time the battery 110 can move freely in the direction of disengaging from the receiving member 11.

[0072] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7 The first locking member 2 has a corner portion 22 at one end near the second locking member 3. The corner portion 22 has a rod-shaped connecting portion connected to the main body of the first locking member 2 and an end portion extending to the end of the rod-shaped connecting portion. The extension direction of the end portion intersects the extension direction of the rod-shaped connecting portion.

[0073] The second locking member 3 can be a rotating structure, rotatably mounted on the receiving member 1, and at least partially overlapping the extension line of the movement trajectory of the first locking member 2. The second locking member 3 is provided with a limiting part 31, which has an opening 311. Preferably, the limiting part 31 is located at the end of the second locking member 3, and is an annular structure protruding from the end of the second locking member 3. The opening 311 is located on the side wall of the annular structure, and the opening 311 extends from the outer ring side wall to the inner ring side wall of the annular structure. The position of the second locking member 3 is configured such that its limiting part 31 is located in the direction pointed to by the corner 22 of the first locking member 2. Please refer to [reference needed]. Figure 3When the second locking member 3 is in the first position and the first locking member 2 moves, the end portion of the corner portion 22 is used to pass through the notch and freely enter and exit the interior of the area enclosed by the restricting portion 31. The end portion extends in a direction close to the second locking member 3, such that the rod-shaped connecting portion of the corner portion 22 is outside the range of the movement trajectory formed when the restricting portion 31 rotates. Thus, after the end portion of the corner portion 22 passes through the notch and enters the interior of the area enclosed by the restricting portion 31, the second locking member 3 can rotate from the first position to the second position. In some embodiments, the angle of rotation required for the first locking member 2 to rotate from the first position to the second position can be 90 degrees, or it can be other angles. During this process, the restricting portion 31 can rotate freely without interfering with the rod-shaped portion of the corner portion 22. Please refer to... Figure 4 When the second locking member 3 rotates to the second position, the limiting part 31 blocks the movement trajectory of the corner part 22, thereby restricting the movement of the first locking member 2 between the locked position and the unlocked position.

[0074] The following is an example of the locking process of the battery compartment locking device 100 in this application embodiment:

[0075] Before installation, move the first locking piece 2 to the unlocked position and move the second locking piece 3 to the first position.

[0076] First, the battery 110 is slidably installed in the receiving part 11. Then, the first locking member 2 is moved from the unlocked position to the locked position. At this time, the locking part 21 abuts against the battery 110 to restrict the movement of the battery 110. At the same time, the corner part 22 enters the space enclosed by the limiting part 31 along the opening 311 on the limiting part 31. Then, the second locking member 3 is rotated to move from the first position to the second position. During this process, the opening 311 on the limiting part 31 rotates at a certain angle and is offset from the movement direction of the corner part 22. The limiting part 31 then rotates synchronously to the movement path of the corner part 22 of the first locking member 2. If the first locking member 2 is to be pulled, the corner part 22 will abut against the inner wall of the limiting part 31, thereby restricting the first locking member 2 from moving from the locked position to the unlocked position.

[0077] After the above locking operation is completed, even if the first locking member 2 fails in extreme circumstances, it is still restricted from moving by the second locking member 3, thereby ensuring that the battery 110 is fixed in the housing 11. In summary, the battery compartment locking device 100 provided in this application, by setting the structural and positional relationship between the first locking member 2 and the second locking member 3, enables the battery compartment locking device 100 to more securely fix the battery 110, preventing the battery 110 from falling off in extreme circumstances and improving the overall safety of the device.

[0078] In one embodiment, the limiting part 31 protrudes from the end of the second locking member 3, the opening 311 extends along the rotation axis perpendicular to the second locking member 3, and the sliding direction of the first locking member 2 is perpendicular to the rotation axis of the second locking member 3.

[0079] The limiting part 31 can be an annular structure with an opening 311 on its side wall. The number of openings 311 can be one or more. When multiple openings 311 are provided, it means that the second locking member 3 can rotate to multiple angles to allow the corner part 22 to pass through openings 311 at different positions. (See also...) Figure 3 , Figure 4 and Figure 6 The limiting part 31 can also be two boss structures. The projection of the boss structure on the second locking member 3 is a curved strip. The two bosses are arranged opposite each other, and the position where the ends of the two bosses are spaced apart is the opening 311. Furthermore, the two bosses roughly enclose an ellipse.

[0080] Because the limiting part 31 is located at the end of the second locking member 3, and the opening 311 on the limiting part 31 extends along the rotation axis perpendicular to the second locking member 3, the opening 311 rotates with the second locking member 3 when it is rotated. Simultaneously, the main body of the limiting part 31 rotates synchronously onto the movement path of the corner part 22, thereby restricting the first locking member 2 from moving from the locked position to the unlocked position. This arrangement makes the structure of the second locking member 3 more compact, thereby reducing the volume of the battery compartment locking device 100, and allows the second locking member 3 to switch between the first and second positions simply by rotating it a certain angle, improving operational efficiency.

[0081] In one embodiment, a guide arc surface 312 is provided on the side of the limiting part 31 near the rotation axis of the second locking member 3. The portion of the guide arc surface 312 away from the opening 311 is closer to the rotation axis of the second locking member 3 than the portion of the guide arc surface 312 near the opening 311.

[0082] Please see Figure 3 and Figure 4The limiting part 31 is provided with a guide arc surface 312 on the side near the rotation axis of the second locking member 3. During the rotation of the second locking member 3, the guide arc surface 312 can be used to apply force to the corner part 22 so that the first locking member 2, which has not moved to the position, can move to the locking position. Specifically, when the first locking member 2 is not fully in place, the end portion of its corner 22 is far from the rotation axis of the second locking member 3. When the second locking member 3 is rotated, the guide arc surface 312 on the limiting part 31 near the opening 311 of the second locking member 3 will contact the end portion of the corner 22. As the second locking member 3 rotates further, the part of the guide arc surface 312 that is far from the opening 311 will gradually contact the end portion of the corner 22. Since the part of the guide arc surface 312 that is far from the opening 311 is closer to the rotation axis of the second locking member 3 than the part of the guide arc surface 312 that is close to the opening 311, when the second locking member 3 rotates to the second position, the corner 22 is closer to the rotation axis of the second locking member 3 under the driving action of the guide arc surface 312. In this way, the first locking member 2 moves into place, ensuring that the locking part 21 and the battery 110 are in full contact, thereby improving the fault tolerance of the battery compartment locking safety device 100.

[0083] In one embodiment, the battery compartment locking device 100 further includes a steering component 4 slidably disposed on the receiving member 1. The sliding direction of the steering component 4 is arranged in the same direction as the rotation axis of the second locking member 3. The steering component 4 includes a pressing block 41 and a ramp block 42 connected to each other. The ramp block 42 abuts against the first locking member 2 and is used to drive the first locking member 2 to move in a direction away from the limiting part 31.

[0084] Please see Figure 5 and Figure 6 The steering assembly 4 includes a pressing block 41 and a ramp block 42 connected to each other. A sliding groove structure for sliding the steering assembly 4 can be formed on the receiving member 1, extending from the surface of the receiving member 1 into its interior. The pressing block 41 can be a cylindrical button structure. The ramp block 42 has a ramp on the side near the first locking member 2. A through hole for the ramp block 42 to pass through can be formed in the middle of the first locking member 2. The ramp block 42 is at least partially inserted into the through hole. (See also...) Figure 5 When the pressing block 41 moves along the rotation axis of the second locking member 3 and toward the direction of the first locking member 2, the inclined block 42 abuts against the first locking member 2 and drives the first locking member 2 to move away from the limiting part 31. During this process, the first locking member 2 also moves synchronously from the locked position to the unlocked position.

[0085] The steering assembly 4 uses the inclined block 42 to push the first locking member 2 to move, thereby changing the transmission trajectory that drives the first locking member 2 to move. In this way, the pressing direction of the rotating assembly is the same as the rotation axis of the second locking member 3. This not only saves space in the battery compartment locking device 100, but also makes the operating surfaces of the first locking member 2 and the second locking member 3 on the same plane, thereby improving the ease of operation of the battery compartment locking device 100.

[0086] In one embodiment, the battery compartment locking device 100 further includes a reset elastic member 5, which is connected to the first locking member 2. The reset elastic member 5 is used to drive the first locking member 2 to move toward the limiting part 31.

[0087] Please see Figure 3 , Figure 5 , Figure 6 and Figure 7 The reset elastic element 5 can be a spring, a rubber column, or other elastic device or structure. The reset elastic element 5 can be a tension spring or a compression spring. One end of the reset elastic element 5 is connected to the first locking element 2, and the other end can be connected to the receiving element 1. Taking the compression spring located between the receiving element 1 and the first locking element 2 as an example, when the operator drives the first locking element 2 to move away from the limiting part 31, the spring is compressed. When the operator releases the first locking element 2, the spring naturally relaxes, causing the first locking element 2 to move towards the limiting part 31 to reset. Therefore, the reset elastic element 5 enables the first locking element 2 to automatically reset between the unlocked and locked positions, simplifying the operation of the battery compartment locking safety device 100.

[0088] In one embodiment, please refer to Figure 7 The battery compartment locking device 100 includes two first locking members 2 and one second locking member 3. The receiving member 1 is provided with two receiving parts 11, and a partition 12 is formed between the two receiving parts 11. The second locking member 3 and the first locking member 2 are both provided on the partition 12, and the second locking member 3 is located between the two first locking members 2.

[0089] Please see Figure 2 The receiving component 1 is provided with two receiving parts 11, which can be arranged left and right at intervals, and a partition 12 is formed between them. The partition 12 can be a partition structure. The partition 12 is provided with two first locking members 2 and one second locking member 3, and the second locking member 3 is located between the two first locking members 2. The two first locking members 2 are symmetrically arranged with the second locking member 3 as the center.

[0090] Please see Figure 7The corner portions 22 of both first locking members 2 are positioned towards the limiting portion 31 of the second locking member 3. The limiting portion 31 has at least two openings 311, symmetrically arranged about the rotation axis of the second locking member 3. Thus, when the second locking member 3 is in the first position, the continuous direction of the two openings 311 coincides with the direction of the line connecting the two first locking members 2. At this time, both first locking members 2 can move freely between the locked and unlocked positions, and the two corner portions 22 can freely pass through their corresponding openings 311. The two first locking members 2 can respectively connect to the batteries 110 in the left and right receiving portions 11. When both first locking members 2 are in the locked position, they lock the two batteries 110 respectively. Subsequently, the second locking member 3 rotates a certain angle to the second position, where the limiting portion 31 blocks the movement trajectory of the two corner portions 22, thus restricting the movement of the two first locking members 2.

[0091] In summary, the battery compartment locking device 100 in this embodiment has two receiving portions 11 on its receiving member 1, and two first locking members 2 and one second locking member 3 are simultaneously provided. Utilizing the linkage relationship of the above structure, the two batteries 110 can be locked synchronously and effectively, making the battery compartment locking device 100 of this application compact in structure and with a large carrying capacity. Moreover, when the two corner portions 22 have not moved into the area enclosed by the limiting portion 31, the two corner portions 22 will interfere with the side wall of the limiting portion 31 near the opening 311. Therefore, the second locking member 3 can only be freely rotated when both batteries 110 are installed in place and the first locking members 2 are fully moved to the locked position, thus further improving the safety of the battery compartment locking device 100.

[0092] In one embodiment, the battery compartment locking device 100 further includes a rotation detection component 6, which includes a signal element 61 disposed on the second locking member 3 and a detection element 62 disposed on the receiving member 1. The signal element 61 and the detection element 62 are disposed correspondingly, and the detection element 62 is used to identify the rotation angle of the signal element 61.

[0093] Please see Figure 8The signal element 61 and the detection element 62 are correspondingly arranged. The signal element 61 can be disposed at the end of the second locking member 3 so that it rotates with the rotation of the second locking member 3, while the detection element 62 can be disposed on the receiving member 1. The signal element 61 can be a photoelectric emitting device, while the detection element 62 can be a photoelectric sensor; the signal element 61 can also be a magnet, and correspondingly, the detection element 62 can be a magnetic induction device. By setting the detection element 62 and the signal element 61 with corresponding functions, the detection element 62 can sense the rotation angle of the signal element 61, and thus determine the position state of the second locking member 3. In this embodiment, by setting the rotation detection component 6, the rotation state of the second locking member 3 can be detected in real time. When the second locking member 3 has not rotated to the correct position, a signal can be issued to warn, thereby improving the safety and stability of the battery compartment locking safety device 100.

[0094] It should be noted that, in conjunction with the aforementioned embodiment which has two first locking members 2 and one second locking member 3, a set of rotation detection components 6 in this embodiment can simultaneously detect the installation status of the two batteries 110 and the position status of the second locking member 3, which greatly saves material costs and has good reliability.

[0095] Once both batteries 110 are properly installed, the aircraft using the battery compartment locking device 100 can detect the electrical connection status of the batteries 110. At this time, if the first locking member 2 of the battery compartment locking device 100 is in the locked position, the second locking member 3 can rotate to the second position. The aircraft can detect the status of the second locking member 3 through the rotation detection component 6, thereby determining the installation status of the batteries 110. Conversely, if the electrical connection of the batteries 110 is normal after installation, i.e., the batteries 110 are not securely fixed, the first locking member 2 is not in the locked position. In this case, the second locking member 3 cannot rotate to the second position. After the aircraft identifies the position status of the second locking member 3 through the rotation detection component 6, it can stop takeoff.

[0096] In one embodiment, the signal element 61 is a magnet, and the detection element 62 is a magnetic field angle sensor.

[0097] The magnet and the magnetic field angle sensor are designed to work together, resulting in high sensitivity and good reliability.

[0098] In one embodiment, the second locking member 3 further includes a handle 32 that extends to the outer side of the surface of the receiving member 1.

[0099] Please see Figure 9 The handle 32 is protruding on the outside of the receiving part 1 to facilitate the operator's grip. The handle 32 can be in the shape of a ball handle 32, a bar handle 32, etc. The handle 32 can improve the convenience of rotating the second locking part 3.

[0100] In one embodiment, the handle 32 has an extension 321, the projection of the extension 321 in the sliding mounting direction of the battery 110 coincides with the battery 110 when the second locking member 3 is in the second position.

[0101] Please see Figure 9 The extension 321 can be a strip-shaped structure extending on the handle 32 body along the direction perpendicular to the rotation axis of the second locking member 3. When the second locking member 3 is in the first position, the extension 321 does not coincide with the projection of the battery 110 in the sliding mounting direction of the battery 110. When the second locking member 3 is in the second position, the extension 321 blocks the sliding mounting path of the battery 110. Thus, even if the first locking member 2 and the second locking member 3 fail, the battery 110 will still be blocked by the extension 321, thereby preventing the battery 110 from coming out under extreme working conditions, thereby further improving the safety of the battery compartment locking device 100.

[0102] This application also provides a drone that includes the battery compartment locking device 100 described in any of the above claims, and thus obviously has the advantages of the battery compartment locking device 100 described above.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
