Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of unmanned aerial vehicles, and in particular to a unmanned aerial vehicle. Background Art

[0002] The batteries of existing drones are generally replaceable. When the battery power is low, the drone can continue to perform flight missions by replacing the battery. However, in existing drones, when replacing the battery, it is generally judged by naked eyes whether the battery is installed properly, which is prone to errors. As a result, the drone may take off without the battery being installed properly. During the flight of the drone, the battery may become loose or even fall off, which may cause the drone to crash. If the battery is not installed properly, it may cause poor electrical contact of the battery, resulting in the drone being unable to power on, and the user may think that the drone is faulty.

[0029] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] See also Figure 1 and Figure 2The drone 100 includes a body 1, a control module 2, a battery 3 and a drive module 4. The control module 2 is mounted on the body 1 and is used to control the flight of the drone 100. The battery 3 is detachably mounted on the body 1, and the drive module 4 is mounted on the body 1. When the battery 3 is mounted on the body 1, the battery 3 is electrically connected to the drive module 4 so that the battery 3 can provide power to the drive module 4. The drive module 4 is electrically connected to the control module 2. The control module 2 is used to control the flight of the drone 100, and the drive module 4 is used to provide power for the flight of the drone 100.

[0031] For the above mentioned machine 1, see Figure 1 and Figure 2 The body 1 is provided with a battery compartment 11, and the battery compartment 11 has a first inner wall 111 and a second inner wall 113 opposite to each other along a first direction X. Please refer to FIG. Figure 5 , Figure 6 and Figure 7 The first inner wall 111 is provided with a first contact member 112, and the control module 2 is electrically connected to the first contact member 112. The body 1 is also provided with a power connection portion 12, at least part of which is exposed to the battery compartment 11, and the control module 2 is electrically connected to the power connection portion 12, and the power connection portion 12 is used to receive the power of the battery 3, so that the battery 3 can supply power to the control module 2. Please refer to Figure 2 , Figure 5 and Figure 7, the battery 3 is detachably mounted in the battery compartment 11, and the battery 3 is provided with a second contact 321 and a power transmission part 311. The battery 3 can be inserted into the battery compartment 11 from the opening of the battery compartment 11 along the second direction Y, and the first direction X and the second direction Y are perpendicular. When the battery 3 is inserted into the battery compartment 11 along the second direction Y, so that the power transmission part 311 contacts with the power connection part 12 to realize the electrical connection therebetween, the battery 3 supplies power to the control module 2, and the control module 2 starts to work at this time. At this time, if the first contact 112 abuts against the second contact 321, the battery 3 is in the first preset position relative to the battery compartment 11, and at this time, the battery 3 is locked in the battery compartment 11; and if the power transmission part 311 and the power connection part 12 are electrically connected, if there is no contact between the first contact 112 and the second contact 321, the control module 2 issues an alarm, which indicates that the battery 3 is not installed in place, that is, the battery 3 is not locked, and the user needs to continue to install the battery 3 in place. In this embodiment, by setting the first contact piece 112 on the first inner wall 111 and setting the second contact piece 321 on the battery 3, when the first contact piece 112 and the second contact piece 321 abut against each other, it indicates that the battery 3 is installed in place. If the first contact piece 112 and the second contact piece 321 do not abut against each other, an alarm is issued through the control module 2, thereby reminding the user that the battery 3 is not completely locked, thereby reminding the user that the battery 3 needs to be installed in place, which is conducive to reducing the situation where the drone 100 takes off without the battery 3 being locked, thereby reducing the risk of the battery 3 loosening or falling off during the flight of the drone 100, and improving the flight safety of the drone 100; in addition, when the battery 3 is completely locked, it indicates that the battery 3 has been installed in place, thereby reducing the risk of poor contact between the power transmission part 311 and the power receiving part 12 of the battery 3.

[0032] In some embodiments, the first contact member 112 is a FPC (Flexible Printed Circuit) cable, and the FPC cable is provided with at least two spaced metal contacts, and the two metal contacts are electrically connected to the control module 2. The second contact member 321 is made of a conductive material, and when the first contact member 112 abuts against the second contact member 321, the second contact member 321 conducts the two metal contacts on the FPC cable. At this time, the control module 2 can detect that there is current passing through the FPC cable, and the control module 2 does not alarm, indicating that the battery 3 has been installed in place; and on the premise that the power receiving part 12 and the power transmission part 311 are electrically connected, if the two metal contacts on the FPC cable are not conducted (that is, the second contact member 321 is not in contact with the FPC cable), there is no current passing through the FPC cable, and the control module 2 alarms at this time, thereby reminding the user to install the battery 3 in place.

[0033] It is understandable that in addition to the above-mentioned method of detecting whether the FPC cable has current, other methods can also be used, such as through pressure detection, that is, a pressure detection film is set on the first contact piece 112, and when the second contact piece 321 abuts against the pressure detection film, the pressure detection film is subjected to pressure, and the control module 2 does not alarm; and under the premise that the power connection part 12 and the power transmission part 311 are electrically connected, the pressure detection film is not subjected to pressure, and the control module 2 issues an alarm.

[0034] For battery 3 above, see Figure 2 and Figure 3 The battery 3 includes a battery body 31 and a first locking member 32. The first locking member 32 is disposed on the battery body 31, and the first locking member 32 can slide relative to the battery body 31 along the first direction X. The first inner wall 111 of the battery compartment 11 is provided with a first locking groove 1111. When the battery 3 is in a first preset position relative to the battery compartment 11, the first locking member 32 is engaged with the first locking groove 1111, thereby locking the battery 3 to the battery compartment 11. In this embodiment, the locking between the battery 3 and the battery compartment 11 is achieved by the engagement between the first locking member 32 and the first locking groove 1111, which has a simple structure and is firmly locked.

[0035] In some embodiments, the power transmission unit 311 is disposed on the battery body 31 .

[0036] In some embodiments, see Figure 5 The battery 3 also includes a first elastic member 33, a first end (unnumbered) of the first elastic member 33 abuts against the battery body 31, and a second end (unnumbered) of the first elastic member 33 abuts against the first locking member 32, wherein the first end and the second end of the first elastic member 33 are opposite to each other along the first direction X. When the battery 3 is in the first preset position, under the elastic force of the first elastic member 33, the first locking member 32 remains engaged with the first locking groove 1111, thereby reducing the risk of the first locking member 32 leaving the first locking groove 1111 during the flight of the drone 100, thereby reducing the risk of the battery 3 loosening or falling off, and improving the safety performance of the drone 100.

[0037] For the first locking member 32, see Figure 2 and Figure 5The first locking member 32 includes a first clamping portion 322, a first connecting portion 323 and a first pressing portion 324. The first pressing portion 324 is connected to one end of the first connecting portion 323, and the first clamping portion 322 is connected to the other end of the first connecting portion 323. When the battery 3 is in the first preset position, the first clamping portion 322 is clamped in the first locking groove 1111, thereby limiting the movement of the battery 3 relative to the battery compartment 11, and achieving the locking between the battery 3 and the battery compartment 11. When the battery 3 needs to be removed, the first pressing portion 324 can be pressed, and the first pressing portion 324 drives the first clamping portion 322 to gradually leave the first locking groove 1111 along the first direction X through the first connecting portion 323, thereby canceling the locking between the battery 3 and the battery compartment 11. At this time, the battery 3 can be taken out of the battery compartment 11. In this embodiment, by providing the first pressing portion 324 and pressing the first pressing portion 324 to make the first clamping portion 322 leave the first locking groove 1111 , the battery 3 can be easily disassembled.

[0038] In some embodiments, see Figure 2 and Figure 5 The first contact member 112 is arranged in the first locking groove 1111, and the second contact member 321 is arranged in the first clamping portion 322. Therefore, when the second contact member 321 arranged in the first clamping portion 322 abuts against the first contact member 112 arranged in the first locking groove 1111, the first clamping portion 322 is at least partially accommodated in the first locking groove 1111, and the battery 3 is in the first preset position, indicating that the battery 3 is locked in the battery compartment 11. In this embodiment, by setting the first contact piece 112 in the first locking groove 1111 and setting the second contact piece 321 in the first clamping portion 322, when the second contact piece 321 abuts against the first contact piece 112, it indicates that at least a portion of the first clamping portion 322 is accommodated in the first locking groove 1111, and further indicates that the first locking piece 32 has locked the battery 3 in the battery compartment 11. Therefore, it is determined that the battery 3 has been installed in place through the contact between the first contact piece 112 and the second contact piece 321, which is beneficial to reduce the risk of misjudgment, thereby improving the safety performance of the drone 100.

[0039] In some embodiments, see Figure 3 and Figure 5The first inner wall 111 of the battery compartment 11 is provided with a first sliding slope 1112, and the distance between the first sliding slope 1112 and the second inner wall 113 gradually decreases along the direction in which the battery 3 is inserted into the battery compartment 11. The first sliding slope 1112 is used to guide the first clamping portion 322 to slide into the first locking groove 1111. Specifically, in the process of loading the battery 3 into the battery compartment 11, the first clamping portion 322 slides along the first sliding slope 1112, and after the first clamping portion 322 slides over the first sliding slope 1112, the first clamping portion 322 enters the first locking groove 1111 under the elastic force of the first elastic member 33, thereby achieving locking between the battery 3 and the battery compartment 11. In this embodiment, by providing the first sliding slope 1112, the first clamping portion 322 can slide into the first locking groove 1111 along the first sliding slope 1112, which can reduce the resistance in the process of loading the battery 3 into the battery compartment 11 and reduce the difficulty of installing the battery 3.

[0040] In some embodiments, see Figure 2 and Figure 6 The second inner wall 113 of the battery compartment 11 is provided with a second locking groove 1131, and the battery 3 further includes a second locking member 34, which is provided on the battery body 31. The second locking member 34 and the first locking member 32 are respectively provided on two opposite surfaces of the battery body 31, and the second locking member 34 can slide along the second direction Y relative to the battery body 31. The second locking member 34 is used to engage the second locking groove 1131 to lock the battery 3 in the battery compartment 11. When the first locking member 32 is engaged with the first locking groove 1111 and the second locking member 34 is engaged with the second locking groove 1131, the battery 3 is in the first preset position, and at this time, the battery 3 is locked in the battery compartment 11. In this embodiment, by providing a second locking slot 1131 and a second locking member 34, by snapping the second locking member 34 into the second locking slot 1131, and at the same time cooperating with the first locking member 32 to snap into the first locking slot 1111, the stability of locking the battery 3 into the battery compartment 11 can be improved, and the risk of the battery 3 loosening relative to the battery compartment 11 can be reduced.

[0041] In some embodiments, the battery 3 further includes a second elastic member 35, a first end (not numbered) of the second elastic member 35 abuts against the battery body 31, and a second end (not numbered) of the second elastic member 35 abuts against the second locking member 34, so that when the battery 3 is in the first preset position, under the elastic force of the second elastic member 35, the second locking member 34 remains engaged with the second locking groove 1131, thereby reducing the risk of the second locking member 34 being disengaged from the second locking groove 1131 without external force intervention, thereby improving the flight safety of the drone 100. The first end and the second end of the second elastic member 35 are opposite to each other along the first direction X.

[0042] For the second locking member 34, please refer to Figure 2 and Figure 6 The second locking member 34 includes a second clamping portion 342, a second connecting portion 343 and a second pressing portion 344. The second pressing portion 344 is connected to one end of the second connecting portion 343, and the second clamping portion 342 is connected to the other end of the second connecting portion 343. When the battery 3 is in the first preset position, the second clamping portion 342 is clamped in the second locking groove 1131, thereby limiting the movement of the battery 3 relative to the battery compartment 11, and realizing the locking between the battery 3 and the battery compartment 11. When the battery 3 needs to be removed, the first pressing portion 324 and the second pressing portion 344 can be pressed at the same time, and the first pressing portion 324 drives the first clamping portion 322 to gradually leave the first locking groove 1111 along the first direction X through the first connecting portion 323, and the second pressing portion 344 drives the second clamping portion 342 to gradually leave the second locking groove 1131 along the first direction X through the second connecting portion 343, thereby canceling the locking between the battery 3 and the battery compartment 11, and the battery 3 can be taken out of the battery compartment 11. In this embodiment, by providing the second pressing portion 344 and pressing the second pressing portion 344 to make the second holding portion 342 leave the second locking groove 1131 , the battery 3 can be easily disassembled.

[0043] In some embodiments, see Figure 2 and Figure 6 The second inner wall 113 of the battery compartment 11 is provided with a second sliding slope 1132. Along the direction in which the battery 3 is inserted into the battery compartment 11, the distance between the second sliding slope 1132 and the first inner wall 111 gradually decreases. The second sliding slope 1132 is used to guide the second clamping portion 342 to slide into the second locking groove 1131. Specifically, in the process of loading the battery 3 into the battery compartment 11, the second clamping portion 342 slides along the second sliding slope 1132, and after the second clamping portion 342 slides over the second sliding slope 1132, the second clamping portion 342 enters the second locking groove 1131 under the elastic force of the second elastic member 35, thereby achieving locking between the battery 3 and the battery compartment 11. In this embodiment, by providing the second sliding slope 1132, the second clamping portion 342 can slide into the second locking groove 1131 along the second sliding slope 1132, which can reduce the resistance in the process of loading the battery 3 into the battery compartment 11 and reduce the difficulty of installing the battery 3.

[0044] In some embodiments, see Figure 2 and Figure 6, a third contact 114 is provided in the second locking groove 1131, and the third contact 114 is electrically connected to the control module 2, and a fourth contact 341 is provided on the second holding portion 342. When the battery 3 is inserted into the battery compartment 11, the power transmission portion 311 is electrically connected to the power connection portion 12, and the second contact 321 is abutted against the first contact 112, and the fourth contact 341 is abutted against the third contact 114, the battery 3 is in a first preset position relative to the battery compartment 11, the first locking member 32 is clamped in the first locking groove 1111, the second locking member 34 is clamped in the second locking groove 1131, and the battery 3 is locked in the battery compartment 11; when the power transmission portion 311 and the power connection portion 12 are electrically connected, and the first contact 112 is not abutted against the second contact 321, and / or, when the power transmission portion 311 and the power connection portion 12 are electrically connected, and the third contact 114 is not abutted against the fourth contact 341, the control module 2 alarms. In this embodiment, by providing the third contact member 114 and the fourth contact member 341, on the premise that the power transmission part 311 and the power receiving part 12 are electrically connected, if the third contact member 114 and the second contact member 321 are not in contact, it indicates that the second locking member 34 is not locked in the second locking groove 1131. At this time, an alarm is sounded through the control module 2 to remind the user that the battery 3 is not completely locked in, and the user is required to lock the battery 3, thereby further reducing the risk of the drone 100 taking off when the battery 3 is not completely locked, thereby improving the flight safety of the drone 100.

[0045] In some embodiments, the third contact 114 is a FPC (Flexible Printed Circuit) cable, and the third contact 114 is provided with at least two spaced contacts, and the two contacts are electrically connected to the control module 2.
