During use, the positive and negative terminals of the battery need to be connected to the drone to establish an electrical connection and supply power. If the connection between the positive and negative terminals of the battery and the drone is not proper, it can easily lead to excessive contact resistance at the connection point. This can cause the battery and its positive and negative terminals to overheat during drone use, resulting in unstable power supply to the drone. In severe cases, it can even cause the battery to burn out, posing a certain safety hazard. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a drone that can detect and provide feedback on the battery connection in real time, thereby ensuring that the positive and negative terminals of the battery are properly connected to the main body of the drone, which is conducive to improving the safety of drone use.

[0027] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0028] like Figure 1 As shown, this utility model proposes a drone, which includes a main body, a battery 40, and a remote controller. The user controls the main body through the remote controller. The main body includes a battery connection detection unit, which includes a first functional component 10, a second functional component 20, and a control component 30. The first functional component 10 is connected to the battery 40, and the control component 30 is connected to the second functional component 20 and communicates with the remote controller. The first functional component 10 includes a power connection part and a communication connection part, and the second functional component 20 includes a power matching part and a communication matching part. When the first functional component 10 and the second functional component 20 are connected, the power connection part can connect with the power matching part, so that the battery 40 is electrically connected to the main body of the drone and the battery 40 can supply power to the main body. The communication matching part can cooperate with the communication connection part. Based on the connection status of the communication matching part and the communication connection part, the control component can receive first information and send second information to the remote controller based on the first information. The second information is used to indicate whether the power matching part and the power connection part are properly connected. The remote controller can receive the second information.

[0029] The battery connection detection unit on the drone can detect whether the battery is properly connected to ensure the safe use of the drone. The first functional component 10 and the second functional component 20 are connected to achieve an electrical connection between the battery 40 and the main body of the drone so as to supply power to the main body through the battery 40. The control component 30 can communicate with the remote controller and can detect whether the power matching unit and the power connection unit are properly connected. When the power matching unit and the power connection unit fail to connect properly, the control unit 30 can receive first information based on the connection status of the communication matching unit and the communication connection unit, and send second information to the remote controller based on the first information. The remote controller receives the second information to remind the user whether the battery and the main body of the drone are connected properly. In particular, if the connection between the power matching unit and the power connection unit becomes loose due to a collision or other circumstances during the flight of the drone, the control unit 30 can promptly send a second message to the remote controller to remind the user. The user can then recall the drone in time to avoid the problem of overheating and melting at the connection between the battery 40 and the main body (such as the positive and negative terminals of the battery 40, the connecting harness, etc.) caused by the drone flying for a long time. This helps to improve the flight safety and reliability of the drone and can solve the problem that the connection of the battery 40 cannot be checked manually when the drone is in the air, which has good practicality.

[0030] In one embodiment, combined with Figure 2 and Figure 3 The first functional component 10 includes an integrated base 11, and a power connection part includes a positive terminal connection post 12 and a negative terminal connection post 13. The positive terminal connection post 12 and the negative terminal connection post 13 protrude from the end of the integrated base 11 away from the battery 40. The positive terminal connection post 12 is electrically connected to the positive terminal of the battery 40 through a first wiring harness 121, and the negative terminal connection post 13 is electrically connected to the negative terminal of the battery 40 through a second wiring harness 131.

[0031] like Figure 4 As shown, the second functional component 20 includes a positioning base 21, and the power matching part includes a positive plug 22 and a negative plug 23. The positive plug 22 and the negative plug 23 protrude from the end of the positioning base 21 away from the control component 30. The positive plug 22 is used to electrically connect with the positive connecting post 12 and is electrically connected to the main body of the UAV through the third wiring harness 221. The negative plug 23 is used to electrically connect with the negative connecting post 13 and is connected to the main body through the fourth wiring harness 231. When the first functional component 10 and the second functional component 20 are connected, the positive connecting post 12 and the positive plug 22 are connected, and the negative connecting post 13 and the negative plug 23 are connected to realize the electrical connection between the battery 40 and the main body, and to supply power to the main body through the battery 40.

[0032] In this example of Embodiment 1, as Figure 2 As shown, a positive electrode socket 122 is provided on the positive electrode connection post 12. When the first functional component 10 and the second functional component 20 are connected, the positive electrode plug 22 can be inserted into the positive electrode socket 122.

[0033] In this example of Embodiment 1, as Figure 2 As shown, a negative electrode socket 132 is provided on the negative electrode connection post 13. When the first functional component 10 and the second functional component 20 are connected, the negative electrode plug 23 can be inserted into the negative electrode socket 132.

[0034] If the positive terminal 12 (positive socket 122) and the positive plug 22 are not properly connected, it can easily cause the first wiring harness 121 and the third wiring harness 221 to overcurrent and overload. And / or, if the negative terminal 13 (negative socket 132) and the negative plug 23 are not properly connected, it can easily cause the second wiring harness 131 and the fourth wiring harness 231 to overcurrent and overload, causing the wiring harness temperature to rise and easily melt, affecting the normal power supply of the drone.

[0035] In this first embodiment example, to improve the connection efficiency of the power connection part and the power matching part, combined with Figure 2 and Figure 3 The positive electrode connecting post 12 and the negative electrode connecting post 13 are spaced apart along the length of the integrated base 11. The positive electrode connecting post 12 is provided with a first positioning element 123, and the negative electrode connecting post 13 is provided with a second positioning element 133. Figure 4 As shown, the positioning seat 21 has a positioning cavity at one end away from the control component 30. The positive electrode plug 22 and the negative electrode plug 23 are located in the positioning cavity. The cavity wall of the positioning cavity is provided with a first fitting 211 that cooperates with the first positioning component 123 and a second fitting 212 that cooperates with the second positioning component 133. When the first functional component 10 and the second functional component 20 are connected, the first positioning component 123 cooperates with the first fitting 211, and the second positioning component 133 cooperates with the second fitting 212.

[0036] For example, the first positioning member 123 is a groove formed on the outer wall of the positive electrode connecting post 12, and the first mounting part 211 is a protrusion protruding on the inner wall of the positioning cavity, or the first positioning member 123 is a protrusion protruding on the outer wall of the positive electrode connecting post 12, and the first mounting part 211 is a groove formed on the inner wall of the positioning cavity.

[0037] For example, the second positioning member 133 is a groove formed on the outer wall of the negative electrode connecting post 13, and the second mounting part 212 is a protrusion protruding on the inner wall of the positioning cavity, or the second positioning member 133 is a protrusion protruding on the outer wall of the negative electrode connecting post 13, and the second mounting part 212 is a groove formed on the inner wall of the positioning cavity.

[0038] For example, the first positioning member 123 is located at the end of the positive electrode connection post 12 away from the negative electrode connection post 13, and the second positioning member 133 is located at the end of the negative electrode connection post 13 away from the positive electrode connection post 12. The first positioning member 123 and the second positioning member 133 cooperate to position the integrated base 11 in the length direction, so as to ensure the connection efficiency of the first functional member 10 and the second functional member 20 and reduce the time for adjusting their relative positions.

[0039] For example, to improve the connection efficiency between the power connection part and the power matching part, the number of the first positioning member 123 is different from the number of the second positioning member 133. Correspondingly, since the first assembly 211 and the first positioning member 123 have a mating relationship, and the second assembly 212 and the second positioning member 133 have a mating relationship, the number of the first assembly 211 and the second assembly 212 is also different. With this arrangement, when making a connection, the position and direction of the positive and negative poles can be directly determined according to the number of the first positioning member 123 and the second positioning member 133, reducing the number of positioning and adjustment times during connection and facilitating connection.

[0040] In one embodiment, such as Figure 2 As shown, the communication connection part includes a first connection hole 14, combined with Figure 4 The communication matching unit includes a first pin 24, which is used to connect to the first connection hole 14 and is capable of sending first information to the control unit 30. The first pin 24 and the first connection hole 14 are configured such that the power matching unit and the power connection unit can be connected in place before the first pin 24 and the first connection hole 14. More specifically, the length of the first pin 24 is configured to be less than the length of the positive plug 22 and / or the negative plug 23, so that the power matching unit and the power connection unit can be connected before the first pin 24 and the first connection hole 14.

[0041] In this example of Embodiment 1, one of the two first connection holes 14 is a 5V power supply connection hole, and the other is a ground connection hole; one of the two first pins 24 is a 5V power supply pin, and the other is a ground pin; and both first pins 24 are electrically connected to the control component 30, such as... Figure 3 As shown, the two first connection holes 14 are electrically connected at the ends near the battery 40 through the first power signal line 141. The aforementioned first information is a level signal. When the two first pins 24 are respectively connected to the two first connection holes 14, a loop can be formed between the first power signal line 141 and the control unit 30, thereby realizing the transmission of the first information.

[0042] Only when the power matching part and the power connection part are properly connected can the first pin 24 connect to the first connection hole 14 and transmit the first information to the control unit 30. At this time, the first information is at a high level. The control unit 30 receives the first information and sends a second information indicating that the connection is in place to the remote control based on the first information. The user can know that the connection between the power matching part and the power connection part is in place by observing the second information displayed on the remote control. When the power matching part and the power connection part are not properly connected, the first pin 24 cannot connect to the first connection hole 14 and transmit the first information to the control unit 30. At this time, the first information is at a low level. The control unit 30 receives the first information and sends a second information indicating that the connection is not in place to the remote control based on the first information. The user can know that the connection between the power matching part and the power connection part is not in place by observing the second information displayed on the remote control.

[0043] In one embodiment, such as Figure 2 As shown, the communication connection part also includes a second connection hole 15, combined with Figure 4 The communication matching unit includes a second pin 25, which can be connected to a second connection hole 15 for transmitting battery information signals to the control unit 30. The battery information signals include at least one of the following signals: voltage, current, charge, number of cycles, and temperature of the battery 40 during charging and discharging.

[0044] For example, the controller 30 can send a battery information signal to the remote controller.

[0045] For example, combined Figure 2 and Figure 3 The two second connection holes 15 are connected to the battery 40 via a connection line 151 at one end.

[0046] For example, the length of the second pin 25 is greater than the length of the first pin 24, but less than the length of the positive plug 22 and / or the negative plug 23. This configuration ensures that the second connection hole 15 can be connected to the second pin 25, and the first connection hole 14 can be connected to the first pin 24, only after the power matching part and the power connection part are in place.

[0047] In this example of Embodiment 1, combined with Figure 2 and Figure 4 The integrated base 11 has a connecting platform 111 protruding from one end away from the battery 40. The connecting platform 111 is located between the positive terminal connecting post 12 and the negative terminal connecting post 13 in the length direction of the integrated base 11. The connecting platform 111 is recessed or protruding from the positive terminal connecting post 12 and the negative terminal connecting post 13 in the width direction of the integrated base 11, so as to cooperate with the positive terminal connecting post 12 and the negative terminal connecting post 13 to form a third positioning member 16. The first connecting hole 14 and the second connecting hole 15 are opened on the connecting platform 111.

[0048] like Figure 4 As shown, the inner wall of the positioning cavity is provided with a third fitting 213 that cooperates with the third positioning member 16. When the connecting platform 111 is recessed, the third fitting 213 is a protrusion on the inner wall of the positioning cavity. When the connecting platform 111 is protruding, the third fitting 213 is a groove opened on the inner wall of the positioning cavity.

[0049] The third positioning component 16 and the third mounting component 213 cooperate to position the integrated base 11 in the width direction, and can cooperate with the first positioning component 123 and the second positioning component 133 to achieve positioning in two directions. This can further ensure the connection efficiency of the first functional component 10 and the second functional component 20, improve the firmness of the connection between the first functional component 10 and the second functional component 20 during the flight of the UAV, and effectively avoid the problem of the connection between the two becoming loose.

[0050] For example, such as Figure 2 As shown, the positive terminal connection post 12 is provided with a fourth positioning element 17 at one end near the negative terminal connection post 13, and / or, the negative terminal connection post 13 is provided with a fourth positioning element 17 at one end near the positive terminal connection post 12, in combination with Figure 4 The positioning cavity is provided with a pin seat 214 protruding therefrom. The first pin 24 and the second pin 25 protrude from the pin seat 214. The pin seat 214 is provided with a fourth mounting part 215 that cooperates with the fourth positioning part 17. The fourth positioning part 17 can cooperate with the first positioning part 123 and the second positioning part 133 to position and limit the positive terminal connecting post 12 and the negative terminal connecting post 13 in the length direction of the integrated base 11, so as to improve the stability of the connection between the first functional part 10 and the second functional part 20.

[0051] In this example of Embodiment 1, as Figure 2 As shown, two first connecting holes 14 are spaced apart along the length of the integrated base 11 and also spaced apart along the width of the integrated base 11. Two second connecting holes 15 are also spaced apart along the length of the integrated base 11 and also spaced apart along the width of the integrated base 11. That is, the center line connecting the two first connecting holes 14 intersects the center line connecting the two second connecting holes 15. This arrangement minimizes the size of the first functional component 10 while still achieving the desired functionality, thereby reducing the flight load on the drone and ensuring its flight quality and user experience.

[0052] In one embodiment, such as Figure 5As shown, the control unit 30 includes a control board 33, which includes signal pins. The signal pins are electrically connected to the first pin 24 and the second pin 25 via a second power signal line 331. When the first pin 24 is connected to the first connection hole 14, it can input a high-level first information to the signal pin connected to the 5V power connection hole. Based on the high-level signal, the signal pin can output the first information to the control unit 30, and the control unit 30 can generate second information to transmit to the remote controller. When the first pin 24 is not connected to the first connection hole 14, the signal pin connected to the 5V power connection hole has no high-level input, that is, it inputs a low-level first information. Based on the low-level signal, the signal pin can output the first information to the control unit 30, and the control unit 30 can generate second information to transmit to the remote controller.

[0053] In this first embodiment, the control unit 30 further includes a first housing 31 and a second housing 32, which are connected to form a cavity for accommodating the control panel 33.

[0054] In this example of Embodiment 1, combined with Figure 4 and Figure 5 The control unit 30 also includes a function board 34, which is communicatively connected to the second function unit 20 via a second power signal line 331, and is electrically and / or communicatively connected to the control board 33.

[0055] In this example of Embodiment 1, as Figure 5 As shown, a positioning post 311 protrudes from the first housing 31, and a positioning hole 332 is provided on the control board 33. The control board 33 is sleeved on the positioning post 311 through the positioning hole 332 to realize the positioning and installation of the control board 33 and the first housing 31. This helps to improve the installation efficiency and ensures that the control board 33 is installed stably, avoiding the control board 33 from shaking during the flight of the UAV and affecting the flight quality and communication quality of the UAV.

[0056] For example, the control board 33 is a PCB (Programmable Logic Controller).

[0057] For example, the first housing 31 and the second housing 32 are detachably connected by screws to facilitate maintenance and repair, and to facilitate replacement of the control board 33 or editing of the functions of the control board 33.

[0058] For example, the control unit 30 can be integrated into the control system of the UAV body, or it can be independent of the control system of the body.

[0059] In this example of Embodiment 1, as Figure 5As shown, the first housing 31 is provided with a mounting plate 35 on its exterior for mounting the second housing 32 onto the main body of the drone.

[0060] For example, the mounting plate 35 can be installed by a fixed connection such as adhesive or welding, or by a detachable connection such as screw or snap-fit.

[0061] In this example of Embodiment 1, the control unit 30 communicates with the remote controller via radio waves to send the aforementioned second information to the remote controller, or to send the second information and battery information. Radio waves offer a longer signal transmission distance and effectively avoid electromagnetic interference, thus ensuring stable communication.

[0062] In this example of Embodiment 1, the remote control includes a display screen. When the remote control receives second information from the control unit 30, or sends the second information along with the aforementioned battery information, the display screen can display prompt words, prompt patterns, or a combination thereof to represent the aforementioned various information.

[0063] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
