Description

Technical Field

[0001] This disclosure relates to the field of battery safety, and more specifically, to a battery safety warning system. Background Technology

[0002] Batteries are essential power supply components in daily life and work. The reliability of battery installation directly impacts work efficiency and safety. For unmanned aerial vehicles (UAVs), batteries are crucial. Given the nature of UAV operation, batteries must be easily removable while maintaining a stable and reliable power supply during connection. In actual flight, even a slight loosening of the battery can lead to detachment or power interruption. In severe cases, this can cause the UAV to crash, resulting in economic losses, and even threatening the safety of personnel on the ground. Battery loosening can be caused by various factors, such as the user not properly installing the battery before takeoff, or external interference or vibrations during flight.

[0003] Although some traditional UAVs have batteries equipped with features to detect whether the electrical connection between the battery and the fuselage is intact, for example, traditional UAV batteries have a presence signal pin and the fuselage's electrical connection socket has a presence signal detection hole. When the battery's presence signal pin is inserted into the presence signal detection hole of the fuselage's electrical connection socket, the presence signal pin inputs a presence detection signal, allowing the UAV to know that the electrical connection between the battery and the fuselage's electrical connection socket is intact and can take off normally.

[0004] However, even with the battery's presence signal pin inserted into the presence signal detection hole of the fuselage's electrical connection socket, proper battery installation is not guaranteed. For example, sometimes even if the battery is not fully installed, the presence signal pin can still partially insert into the presence signal detection hole, allowing the UAV to still detect a normal battery connection and take off normally. Alternatively, even if the battery is properly installed and takes off normally, the battery may still become loose during flight. For example, a minor impact or severe vibration in a windy environment could cause the battery to detach from its mounting section. Therefore, due to the lack of indication of battery security, battery loosening during flight is often the leading cause of aircraft crashes. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this disclosure provides a battery safety warning system. By sending warning messages to users, the system alerts them to problems such as loose or unreliable battery connections in unmanned aerial vehicles (UAVs). This allows users to check the battery connections and reinstall the battery properly before takeoff if the battery is not installed correctly, ensuring a safe takeoff. Alternatively, it informs users during flight that a loose battery condition necessitates a safe landing to avoid serious consequences such as a crash.

[0006] This disclosure provides a battery safety warning system, which includes a detection device for detecting the position information of a locking mechanism. One of the battery and the battery mounting portion has the locking mechanism, and the other has a mating mechanism. The locking mechanism engages with the mating mechanism to fix the battery in the battery mounting portion. A controller is also included, communicatively connected to the detection device, for receiving the position information of the locking mechanism detected by the detection device. The controller determines that the locking mechanism and the mating mechanism are properly engaged based on the position information. If the locking mechanism and the mating mechanism are not properly engaged, the controller issues a corresponding warning message.

[0007] In some embodiments, the detection device is one or more sensors, including Hall effect sensors, photoelectric sensors, microswitches, etc.

[0008] In some embodiments, the position information detected by the detection device is the moving distance of the engaging mechanism or the rotation angle of the engaging mechanism.

When the hook rotates to the first preset angle position, the hook engages with the slot. When the hook rotates to the second angle position, the hook separates from the slot; wherein, the detection device is located at the bottom of the slot or at the edge of the slot; or, the mating mechanism has a buckle, and the hook can rotate between a first preset angle position and a second angle position, wherein when the hook rotates to the first preset angle position, the hook engages with the buckle; when the hook rotates to the second angle position, the hook separates from the buckle; wherein, the detection device is located at the buckle.

[0014] In some embodiments, the controller is connected to the detection device via a wired or wireless connection.

[0015] Furthermore, if the detection value of the detection device is less than or equal to the preset value, it indicates that the engagement is not in place, and the controller issues a corresponding prompt.

[0016] Alternatively, if the detection value of the detection device is equal to or greater than a preset value, it indicates that the engagement is not complete, and the controller issues a corresponding prompt.

[0017] Furthermore, when the engaging mechanism and the mating mechanism are engaged in place, the controller also issues a prompt message to indicate that the engagement is complete.

[0018] Furthermore, both the controller and the detection device are mounted on the battery, or both the controller and the detection device are mounted on the battery mounting portion.

[0040] Detailed Implementation

[0041] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0042] It should be noted that when a component is described as "fixed to" another component, it can be directly attached to the other component or may have an intervening component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or may have an intervening component; where possible, the two components can also be integrally formed. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] This disclosure provides a battery safety warning system for detecting whether a battery is securely fixed. The battery safety warning system uses a detection device to check the battery's fixation. For example, one of the battery and the battery mounting part has a locking mechanism, and the other has a mating mechanism. The locking mechanism and the mating mechanism cooperate to fix the battery in the battery mounting part.

[0045] When the detection device checks the battery's fixation, it can employ different methods. For example, in one embodiment, the detection device can detect the relative position information of the locking mechanism and the mating mechanism. Based on this relative position information, it can determine whether the locking mechanism and the mating mechanism are properly engaged, ensuring that the battery is securely fixed to the battery mounting portion. For instance, the relative position information could be the relative distance between the locking mechanism and the mating mechanism, or the staggered distance between them.

[0046] In one embodiment, the detection device can detect the position information of the engaging mechanism, and thereby determine whether the engaging mechanism and the mating mechanism are properly engaged based on the position information of the engaging mechanism, so as to ensure that the battery can be securely fixed to the battery mounting part. The position information of the engaging mechanism can be the moving distance of the engaging mechanism, or the rotation angle of the engaging mechanism, etc.

[0047] In one embodiment, the detection device can detect the relative position information between the battery and the battery mounting portion, and thereby determine whether the engaging mechanism and the mating mechanism are properly engaged based on the relative position information, so as to ensure that the battery can be securely fixed to the battery mounting portion. The relative position information can be the depth of the battery within the battery mounting portion, or the sliding distance of the battery relative to the battery mounting portion, etc.

[0048] Battery safety warning systems can be applied to different devices. For example, they can be installed on batteries (e.g., smart batteries), on powered devices (e.g., drones, handheld gimbals, remote-controlled ground vehicles), or on charging devices (e.g., chargers, battery managers).

[0049] The alerts generated by the battery safety alert system can be sent to the battery controller, the controller of the powered device, the controller of the remote control device of the powered device, or the processor of the charging device, so that these processors can perform corresponding control operations.

[0050] In one implementation, the battery safety warning system can send warning messages to the battery controller. Based on these messages, the battery controller can control the connection or disconnection of electrical pathways, or issue an alarm. For example, when the battery is supplying power and the battery safety warning system sends a warning message indicating the battery is not securely fastened, the battery controller can stop supplying power. When the battery is charging and the battery safety warning system sends a warning message indicating the battery is not securely fastened, the battery controller can stop charging. When the battery is in use (e.g., charging, discharging) and the battery safety warning system sends a warning message indicating the battery is not securely fastened, the battery controller can control an alarm device to issue an alarm, such as illuminating an alarm light, emitting an alarm sound from a speaker, or causing a vibrator to vibrate.

[0051] In one implementation, the battery safety warning system can send a warning message to the controller of the powered device. Based on this warning message, the controller can disconnect the powered circuit, control the power unit to perform corresponding operations, or issue an alarm. For example, when the UAV is on the ground and has not yet taken off, if the battery safety warning system sends a warning message indicating that the battery is not securely fastened, the UAV's controller can prevent takeoff by controlling the power system, or control the alarm device to issue an alarm, or send the warning message to the UAV's remote controller. When the UAV is in flight, if the battery safety warning system sends a warning message indicating that the battery is not securely fastened, the UAV's controller can control the alarm device to issue an alarm, or send the warning message to the UAV's remote controller.

[0052] In one implementation, the battery safety warning system can send warning messages to the controller of the remote control of the powered device. Based on these warning messages, the controller can generate selective control information for the user or issue an alarm. For example, when an unmanned aerial vehicle (UAV) is in flight and the battery safety warning system sends a warning that the battery is not securely fastened, the UAV's remote controller can either control the alarm device to issue an alarm or generate control information for the user regarding whether to land immediately. The user can then choose whether to control the UAV to land immediately.

[0053] The various embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The illustrated embodiments are only used to explain the implementation of this disclosure and should not be construed as limiting this disclosure.

[0054] Please see Figure 1 The battery safety warning system 110 provided in this embodiment includes a detection device 111 and a controller 113. The detection device 111 is communicatively connected to the controller 113. For example, the detection device 111 and the controller 113 can be communicatively connected via a wired connection or a wireless connection.

[0055] Please see Figure 2a The battery 101 is stably fixed to the battery mounting part 103 by engaging with the locking mechanism 120 and cooperating with the cooperating mechanism 130. The battery safety warning system 110 is used to detect whether the locking mechanism 120 and the cooperating mechanism 130 are properly engaged.

[0056] The detection device 111 can check various motion information of the engaging mechanism. For example, in one embodiment, the detection device 111 can be a displacement detection device to detect the moving distance of the engaging mechanism 120. Of course, in other embodiments, the detection device 111 can also be an angle detection device to detect the rotation angle of the engaging mechanism 120.

[0057] The detection device 111 can be of different types depending on different needs. For example, in one embodiment, the detection device 111 uses the principle of magnetoelectric effect to detect the position information of the locking mechanism 120. The corresponding detection device 111 can be a Hall sensor, or a Hall detection device. Alternatively, in other embodiments, the detection device 111 uses the principle of photoelectric effect to detect the position information of the locking mechanism 120. The corresponding detection device 111 can be a photoelectric sensor, or a photoelectric detection device. Alternatively, in other embodiments, the detection device 111 can be a micro switch.

[0058] The location of the controller 113 can be designed according to different requirements. For example, in one embodiment, the controller 113 and the detection device 111 may both be located on the battery 103. In other embodiments, the controller 113 and the detection device 111 may both be located on the battery mounting portion 103. Please refer to [link to relevant documentation]. Figure 7 In some other embodiments, the controller 113 may also be disposed on the battery 101 and the remote controller 300 respectively; or the controller may be disposed on the battery mounting part 103 and the remote controller 300 respectively.

[0059] The controller 113 is used to communicate with the detection device 111 and to receive the position information of the locking mechanism 120 detected by the detection device 111. The communication connection can be either wired or wireless.

[0060] The engaging mechanism 120 is movable relative to the cooperating mechanism, for example, in... Figure 2a In this embodiment, the engaging mechanism 120 is slidable relative to the mating mechanism 130, and correspondingly, the detection device 111 can be a displacement detection device. The position information of the engaging mechanism 120 detected by the displacement detection device can be the moving distance of the engaging mechanism 120.

[0061] In its Figure 2b In this embodiment, the engaging mechanism 120 is rotatable relative to the mating mechanism 130, and correspondingly, the detection device 111 can be an angle detection device. The position information of the engaging mechanism 120 detected by the angle detection device is the angle of rotation of the engaging mechanism 120.

[0062] The positions of the engaging mechanism 120 and the cooperating mechanism 130 can be designed according to different needs, for example, in... Figure 2a In one embodiment, the engaging mechanism 120 can be disposed on the battery 101, and the mating mechanism 130 can be disposed on the battery mounting portion 103. Alternatively, in its Figure 2b In one embodiment, the engaging mechanism 120 may be provided on the battery mounting portion 103, and the mating mechanism 130 may be provided on the battery 101.

[0063] The specific structures of the engaging mechanism 120 and the mating mechanism 130 can be designed according to different needs, for example, in... Figure 2a In this embodiment, the mating mechanism 130 is provided with a slot, and the engaging mechanism 120 is provided with a hook for engaging with the slot. The hook on the engaging mechanism 120 can slide into the slot to engage with it, or slide into the slot to disengage from it. Figure 2aIn this embodiment, the mating mechanism 130 is provided with a first hook, and the engaging mechanism 120 is provided with a second hook for engaging with the first hook. The second hook on the engaging mechanism 120 can slide relative to the first hook and engage with or disengage from the first hook. The engaging mechanism 120 engages with the mating mechanism 130 to fix the battery 101 to the battery mounting portion 103. When the engaging mechanism 120 disengages from the mating mechanism 130, the battery 101 can be freely detached from the battery mounting portion 103.

[0064] The position of the detection device 111 can be designed according to different needs. For example, in one embodiment, the detection device 111 can be disposed on the engaging mechanism 120. Of course, in other embodiments, the detection device 111 can also be disposed on the mating mechanism 130. The following examples illustrate how the movement information of the engaging mechanism 120 is detected when the detection device 111 is disposed in different positions.

[0065] (a) The detection device is located in the locking mechanism

[0066] Please see Figure 2a When the detection device 111 detects the moving distance of the engaging mechanism 120, the detection method of the detection device 111 can be designed according to different requirements. For example, in Figure 2a In this embodiment, the detection device 111 can be mounted on the latch and a preset value for a moving distance can be set. When the moving distance of the latching mechanism 120 detected by the detection device 111 is greater than the preset value, it indicates that the latching is in place. When the moving distance of the latching mechanism 120 detected by the detection device 111 is less than or equal to the preset value, it indicates that the latching mechanism 120 and the mating mechanism 130 are not properly latched. The controller issues a corresponding prompt message, indicating that the battery 101 and the battery mounting base 103 are not properly installed, reminding the user to recheck and install the battery 101 to ensure a safe and reliable connection between the battery 101 and the battery mounting base 103. In some cases, when the latching mechanism 120 and the mating mechanism 130 are properly latched, the controller 113 can also issue a prompt message indicating that the latching is in place, reminding the user that the battery 101 is reliably installed and can be used with confidence.

[0067] In another embodiment, the detection device 111 is still located on the hook, and a preset value for the movement distance is set. When the movement distance of the engaging mechanism 120 detected by the detection device 111 is less than the preset value, it indicates that the engagement is complete. When the movement distance of the engaging mechanism 120 detected by the detection device 111 is greater than or equal to the preset value, it indicates that the engaging mechanism 120 and the mating mechanism 130 are not fully engaged. The controller 113 issues a corresponding prompt message, indicating that the battery 101 and the battery mounting base 103 are not properly installed, reminding the user to recheck and install the battery 101 to ensure a safe and reliable connection between the battery 101 and the battery mounting base 103. In some cases, when the engaging mechanism 120 and the mating mechanism 130 are fully engaged, the controller 113 can also issue a prompt message to indicate that the engagement is complete, reminding the user that the battery 101 is reliably installed and can be used with confidence.

[0068] Please see Figure 2b When the detection device 111 detects the rotation angle of the engaging mechanism 120, the detection method of the detection device 111 can be designed according to different needs. For example, in one embodiment, the detection device 111 can be disposed on the engaging mechanism 120. The engaging mechanism 120 can rotate at a certain angle relative to the mating mechanism 130. The corresponding detection device 111 can be an angle detection device. The position information of the engaging mechanism 120 detected by the angle detection device 111 is the rotation angle of the engaging mechanism 120. The engaging mechanism 120 can be disposed on the battery 101, and the mating mechanism 130 can be disposed on the battery mounting part 103. Alternatively, the engaging mechanism 120 can be disposed on the battery mounting part 103, and the mating mechanism 130 can be disposed on the battery 101. When the included angle between the engaging mechanism 120 and the mating mechanism 130 is less than a certain value, it can indicate that they are engaged. When the included angle between the engaging mechanism 120 and the mating mechanism 130 is greater than a certain value, it can indicate that they are separated. The controller 113 is communicatively connected to the detection device 111 and is used to receive the position information of the locking mechanism 120 detected by the detection device 111.

[0069] The specific connection method between the detection device 111 and the engaging mechanism 120 can be designed according to different needs. For example, in one embodiment, the detection device 111 is connected to the rotating shaft of the hook of the engaging mechanism 120. In this case, the detection device can be an angle encoder. The engaging mechanism 130 is provided with a slot or a buckle, and two rotation angle values ​​can be preset, namely a first preset angle and a second preset angle. In another embodiment, the detection device 111 can be fixed on the engaging mechanism 120 and the engaging mechanism 130. In this case, the detection device 111 includes a magnet located at the free end of the hook and a Hall sensor located on the engaging mechanism.

[0070] The latch can rotate around the pivot between a first preset angle position and a second angle position. When the latch rotates to the first preset angle position, it engages with the slot or buckle, indicating that the latching mechanism 120 and the mating mechanism 130 are properly engaged. When the latch rotates to the second angle position, it disengages from the slot or buckle, indicating that the latching mechanism 120 and the mating mechanism 130 are not properly engaged, and the controller 113 will issue a corresponding prompt. When the controller 113 issues the corresponding prompt, it indicates that the battery 101 is not properly installed between the battery and the battery mounting base 103, and the user should re-check and reinstall the battery 101 to ensure a safe and reliable connection between the battery 101 and the battery mounting base 103. In some cases, when the latching mechanism 120 and the mating mechanism 130 are properly engaged, the controller 113 will also issue a prompt indicating that the battery 101 is properly installed and can be used with confidence.

[0071] (b) The detection device is located in the cooperating mechanism

[0072] When the detection device 111 is located on the mating machine 130, and the detection device 111 detects the movement distance of the engaging mechanism 120, the detection method of the detection device 111 can be designed according to different needs. For example, in one embodiment, the detection device 111 can be located at the bottom of the slot or near the slot, and a preset value for the movement distance can be set. When the distance moved by the engaging mechanism 120 relative to the mating mechanism 130 detected by the detection device 111 is less than the preset value, it indicates that the engagement is in place. When the distance moved by the engaging mechanism 120 relative to the mating mechanism 130 detected by the detection device 111 is greater than or equal to the preset value, it indicates that the engaging mechanism 120 and the mating mechanism 130 are not engaged in place. The controller issues a corresponding prompt message, indicating that the battery 101 and the battery mounting base 103 are not properly installed, reminding the user to recheck and install the battery 101 to ensure a safe and reliable connection between the battery 101 and the battery mounting base 103. In certain situations, when the engaging mechanism 120 and the mating mechanism 130 are engaged in place, the controller 113 can also issue a prompt message to indicate that the engagement is in place, so as to remind the user that the battery 101 is installed reliably and can be used with confidence.

[0073] In another embodiment, the detection device 111 is still located at the bottom of the card slot or near the card slot, and a preset value for the moving distance is set. When the distance moved by the engagement mechanism 120 relative to the mating mechanism 130 detected by the detection device 111 is greater than the preset value, it indicates that the engagement is in place. When the distance moved by the engagement mechanism 120 relative to the mating mechanism 130 detected by the detection device 111 is less than or equal to the preset value, it indicates that the engagement mechanism 120 and the mating mechanism 130 are not properly engaged. When the battery 101 is not properly installed with the battery mounting base 103, the controller 113 issues a corresponding prompt message to remind the user to recheck and install the battery 101 to ensure a safe and reliable connection between the battery 101 and the battery mounting base 103. In some cases, when the engagement mechanism 120 and the mating mechanism 130 are properly engaged, the controller 113 can also issue a prompt message to indicate that the engagement is in place, to remind the user that the battery 101 is reliably installed and can be used with confidence.

[0074] When the detection device 111 is located on the mating mechanism 130, and the detection device 111 detects the rotation angle of the engaging mechanism 120, the position information of the engaging mechanism 120 detected by the angle detection device 111 is the angle of rotation of the engaging mechanism 120 relative to the mating mechanism 130. The mating mechanism 130 may have a slot, and the detection device 111 may be located at the bottom of the slot or at the edge of the slot. The detection device 111 may be preset with two rotation angle values, namely a first preset angle and a second preset angle, and the hook can rotate around the axis between the first preset angle position and the second preset angle position. When the hook rotates to the first preset angle position, the hook engages with the slot, indicating that the engaging mechanism 120 and the mating mechanism 130 are engaged in place. When the controller 113 issues a corresponding prompt message, it indicates that the battery 101 and the battery mounting base 103 are not properly installed, and the user should re-check and install the battery 101 to ensure that the connection between the battery 101 and the battery mounting base 103 is safe and reliable. In certain situations, when the engaging mechanism 120 and the mating mechanism 130 are engaged in place, the controller 113 also issues a prompt message to indicate that the engagement is complete, so as to remind the user that the battery 101 is installed reliably and can be used with confidence.

[0075] In another embodiment, the mating mechanism 130 is provided with a buckle, and the detection device 111 can be disposed on the buckle. The detection device 111 can be preset with two rotation angle values, namely a first preset angle and a second preset angle, and the hook can rotate around a pivot between the first preset angle position and the second angle position. When the hook rotates to the first preset angle position, the hook and the buckle engage, indicating that the engaging mechanism 120 and the mating mechanism 130 are engaged in place. When the hook rotates to the second angle position, the hook and the buckle separate, indicating that the engaging mechanism 120 and the mating mechanism 130 are not engaged in place, and the controller 113 issues a corresponding prompt message. When the controller 113 issues a corresponding prompt message, it indicates that the battery 101 and the battery mounting base 103 are not properly installed, and the user should re-check and install the battery 101 to ensure that the connection between the battery 101 and the battery mounting base 103 is safe and reliable. In certain situations, when the engaging mechanism 120 and the mating mechanism 130 are engaged in place, the controller 113 also issues a prompt message to indicate that the engagement is complete, so as to remind the user that the battery 101 is installed reliably and can be used with confidence.

[0076] The battery safety warning system 110 can detect the engagement status of one engaging mechanism 120 and a mating mechanism 130, or it can simultaneously detect the engagement status of multiple engaging mechanisms 120 and mating mechanisms 130. Please refer to [link / reference]. Figure 3 The circuit diagram in some embodiments includes two detection devices 111a and 111b. Each detection device may include two microswitches 111a and 111b. The two microswitches 111a and 111b may be connected in series in the circuit and may also be communicatively connected to the controller 113. The communication connection may be wired or wireless.

[0077] Two microswitches 111a and 111b are triggered by two locking mechanisms 120 respectively. When the two microswitches 111a and 111b are triggered at the same time, the link formed by the two microswitches 111a and 111b will be connected, indicating that the two locking mechanisms 120 are locked in place at the same time, and the battery is in a relatively stable state.

[0078] In some embodiments, the battery safety reminder system 110 described in the above embodiments may further include an alarm device that is communicatively connected to the controller 113. The alarm device is used to remind the user whether the battery installation is reliable, thereby achieving the purpose of battery safety.

[0079] The alarm form of the alarm device may include at least one of image display, sound display, light display or vibration reminder, and correspondingly, the alarm device may include at least one of display screen, speaker, light or vibrator.

[0080] The location of the alarm device can be designed according to different needs. For example, the alarm device can be installed on the battery, on the powered equipment, the charging device, or on the remote control device of the powered equipment.

[0081] Based on the battery safety warning system described above, embodiments of this disclosure also provide an unmanned aerial vehicle (UAV) that applies the battery safety warning system described above. The following description of the UAV according to embodiments of this disclosure is illustrated in conjunction with figures.

[0082] Please see Figure 4a The unmanned aerial vehicle 100 provided in this embodiment includes a fuselage 105, a battery 101, a battery mounting part 103, a battery housing 107, a locking mechanism 120, a mating mechanism 130, and also includes a battery safety warning system 110 (not shown in the figure) that includes the above-described embodiments.

[0083] The battery 101 also includes a battery housing 107 for protecting the battery 101. The battery housing 107 is located on the outside of the battery 101 and can enclose the battery 101 therein.

[0084] The battery mounting section 103 is located inside the body 105, and the battery 101 can be mounted on the battery mounting section 103.

[0085] The engaging mechanism 120 can be located on the battery 101 or on the battery mounting section 103. Correspondingly, the mating mechanism 130 can be located on the battery mounting section 103 or on the battery 101.

[0086] Figure 4a The image shows the unmanned aerial vehicle (UAV) 100, which includes a battery safety warning system 110, with the battery 101 separated from the battery mounting section 103. In this state, the UAV 100 cannot fly normally. Figure 4b The image shows the unmanned aerial vehicle (UAV) 100, which includes a battery safety warning system 110, with its battery 101 and battery mounting section 103 installed in place. In this state, the UAV 100 can fly normally.

[0087] For a better explanation of the specific structure of battery 101, please refer to [reference needed]. Figure 5 A cross-sectional view of the battery 101 of the unmanned aerial vehicle 100. The battery 101 provides power to the unmanned aerial vehicle 100. The engaging mechanism 120 is provided on the battery 101 and may be symmetrically distributed on the left and right sides of the battery.

[0088] Please see Figure 6Specifically, a perspective view of the battery 101 of some of the above embodiments is provided. The battery 101 may be enclosed by a battery casing 107 for protection. The engaging mechanism 120 is symmetrically distributed on the left and right sides of the battery.

[0089] Please see Figure 4a This embodiment provides the optimal implementation of the unmanned aerial vehicle 100 in this disclosure. The unmanned aerial vehicle 100 includes the battery safety warning system 110 described above, as well as a battery 101, a battery mounting part 103, a fuselage 105, a battery housing 107, a locking mechanism 120, and a mating mechanism 130.

[0090] The battery mounting section 103 is mounted on the body 105. The engaging mechanism 120 is slidable relative to the mating mechanism 130. The mating mechanism 130 can be symmetrically arranged on both sides of the battery mounting section 103. The engaging mechanism 120 is also symmetrically arranged on the left and right sides of the battery 101.

[0091] The mating mechanism 130 is provided with a slot. The engaging mechanism 120 includes a hook for engaging with the slot of the mating mechanism 130. The hook of the engaging mechanism 120 can slide into the slot of the mating mechanism 130 and engage with the slot. Alternatively, the hook of the engaging mechanism 120 can slide out of the slot of the mating mechanism 130 and separate from the slot. There are also two detection devices 111, symmetrically arranged on the hooks of the engaging mechanism 120 on both sides of the battery 101. Since the engaging mechanism 120 is slidable relative to the mating mechanism 130 in this embodiment, the corresponding detection devices 111a and 111b are displacement detection devices. The displacement detection devices 111a and 111b are specifically microswitches. The two microswitches distributed on both sides of the battery 101 are connected in series in the circuit.

[0092] In this embodiment, the position information of the engaging mechanism 120 is detected by microswitches. Specifically, this position information is the movement distance of the engaging mechanisms 120 on the left and right sides of the battery 101. The microswitches are used in series in the circuit, and the two microswitches 111a and 111b are triggered by the two engaging mechanisms 120 respectively. When one of the microswitches is off, one of the corresponding engaging mechanisms 120 is not engaged properly. When the engaging mechanism 120 and the mating mechanism 130 are not engaged properly, the battery safety warning system 110 will indicate that the connection of the battery 101 is unreliable, and the user needs to check and reinstall the battery 101 properly.

[0093] Specifically, in the illustrated embodiment, the two microswitches connected in series are normally closed switches. If the latches of both the left and right engagement mechanisms 120 trigger the microswitches, it indicates that both engagement mechanisms 120 and mating mechanisms 130 are fully engaged. When both engagement mechanisms 120 and mating mechanisms 130 are fully engaged, the MCU_INT detection should be high, indicating to the user that the battery 101 connection is reliable and that the drone can perform operations such as takeoff. When one latch slides and triggers the corresponding microswitch, causing one of the microswitches to open, it indicates that one engagement mechanism 120 and mating mechanism 130 are not fully engaged. When one engagement mechanism 120 and mating mechanism 130 are not fully engaged, the MCU_INT detection signal should be low, and the controller 113 issues a corresponding prompt, indicating to the user that the battery 101 connection is unreliable and the connection of battery 101 should be rechecked. Similarly, if the sliding of the hook on the other side triggers one of the corresponding microswitches, causing the microswitch to open, it indicates that one side of the engaging mechanism 120 and the mating mechanism 130 is still not fully engaged. At this time, the MCU_INT will still detect a low level, and the controller 113 will still issue a prompt message, reminding the user that the battery 101 is not installed correctly or the connection is unreliable. Of course, if both sides trigger the microswitches, causing both microswitches to open, the MCU_INT will also be low, and the controller 113 will also issue a corresponding prompt message, reminding the user to check the connection of the battery 101.

[0094] In this embodiment, a microswitch is used to detect the movement distance of the locking mechanism 120, ensuring that the hook of the locking mechanism 120 moves within a preset distance, thereby ensuring that the battery 101 and the battery mounting part 103 are tightly engaged. If the detected hook movement distance exceeds the preset distance, the safety prompt system 110 reminds the user to engage the battery 101 properly. Furthermore, if the battery is not properly installed before takeoff, some functions of the unmanned aerial vehicle 100 can be restricted through program settings, such as preventing the unmanned aerial vehicle 100 from taking off if a prompt indicates that the battery is not properly installed.

[0095] Please see Figure 7 In some embodiments, the unmanned aerial vehicle 100 also includes an alarm device 115 and a remote controller 300.

[0096] The remote controller 300 may be equipped with a controller 113b and an alarm device 115. The remote controller 300 and the unmanned aerial vehicle 100 can be connected wirelessly.

[0097] The controller 113b and the detection device 111 can be connected wirelessly to receive signals from the detection device 111 and issue corresponding control information.

[0098] The alarm device 115 can be installed on the remote controller 300 or on the fuselage 105 of the unmanned aerial vehicle 100. The function of the alarm device 115 is to remind the user whether the battery installation is reliable, thereby achieving the purpose of battery safety. The alarm can take the form of at least one of image display, sound display, light display, or vibration alert, and the corresponding alarm device can include at least one of a display screen, speaker, light, or vibrator.

[0099] exist Figure 7 In this embodiment, the detection device is mounted on the locking mechanism 120. Two controllers 113 are respectively mounted on the main body 105 and the remote controller 300. The detection device 111 and the controller 113a mounted on the main body 105 can be connected via wired or wireless means. The detection device 111 and the controller 113b mounted on the remote controller 300 can be connected wirelessly.

[0100] Please see Figure 8 In this embodiment, the unmanned aerial vehicle (UAV) 200 includes a fuselage 205, a battery safety warning system 210, a battery 201, a battery mounting section 203, a locking mechanism 220, a mating mechanism 230, an alarm device 215, and a remote controller 400. A detection device is mounted on the mating mechanism 230. There are two controllers 213, one mounted on the fuselage 205 and the other on the remote controller 400. The detection device 211 and the controller 213a mounted on the fuselage 205 can be connected via wired or wireless means. The detection device 211 and the controller 213b mounted on the remote controller 400 can be connected wirelessly. The alarm device 215 is used to warn that the battery is not properly installed, serving as a reminder. The alarm device 215 can be mounted on the remote controller 400 or on the fuselage 205 of the UAV 200.

[0101] For example, in one embodiment, the alarm is an image display, and the corresponding alarm device 115 is a display screen located on the remote control 300. If the detection device 111 detects that the engaging mechanism 120 and the mating mechanism 130 are not properly engaged, the display screen of the alarm device 115 will display an image to remind the user that the battery 101 is not properly installed.

[0102] For example, in another embodiment, the alarm combines image display with illumination, and the corresponding alarm device 115 consists of a display screen and a light. The display screen is located on the remote control 300, and the light is located on the device body 105. If the detection device 111 detects that the engaging mechanism 120 and the mating mechanism 130 are not properly engaged, the display screen on the remote control 300 will display an image, and the light on the device body 105 will also illuminate. Both alarm devices operate simultaneously, so the user can know that the battery 101 is not properly installed upon receiving either alarm message.

[0103] For example, in another implementation, the alarm is a combination of light and vibration. The corresponding alarm device 115 is a light and a vibrator, which can both be installed on the fuselage 105. If the detection device 111 detects that the engaging mechanism 120 and the mating mechanism 130 are not properly engaged, the two alarm devices, the light and the vibrator, installed on the fuselage 105, will work simultaneously. Whether the user observes with their eyes or touches the UAV 100, they will receive an alarm message and know that the battery 101 is not installed properly.

[0104] Because the aforementioned unmanned aerial vehicle (UAV) 100 employs a battery safety warning system 110, it can alert the user before takeoff whether the battery 101 is securely installed. During UAV 100 flight, it can also promptly alert the user if the battery 101 becomes loose. This disclosure significantly improves the reliability of the UAV 100's battery system, greatly enhancing the reliability of the battery 101 connection. Users using this disclosure do not need to worry about the battery 101 falling off due to improper installation after takeoff, nor do they need to worry about the battery 101 becoming loose due to UAV 100 vibration and going unnoticed. The battery safety warning system 110 can issue a safety warning message if the battery 101 becomes loose before or during UAV 100 takeoff. If the safety warning message appears during UAV 100 flight, the user can safely land the UAV 100 manually and check the battery 101 installation after landing. This can effectively reduce the accident rate of unmanned aerial vehicles (UAVs) by 100%, decrease the risk of crashes or explosions caused by battery detachment, and effectively avoid losses.
