DETAILED DESCRIPTION OF THE EMBODIMENTS

Technical solutions of the present disclosure will be described in detail with reference to the drawings. It will be appreciated that the described embodiments are some rather than all of the embodiments of the present disclosure. Other embodiments conceived by those having ordinary skills in the art on the basis of the described embodiments without inventive efforts should fall within the scope of the present disclosure.

It should be noted that, a mechanism being “fixed to” a second mechanism may include a direct contact of the first and second mechanisms, or may include no direct contact but a contact through other mechanisms in between. A mechanism being “connected to” a second mechanism may include a direct connection of the first and second mechanisms, or may include no direct connection but a connection through other mechanisms in between, or may include a direct integration of the two mechanisms. Terms of “vertical,” “horizontal,” “left,” “right,” etc., are only for illustrative purposes.

Unless otherwise defined, all technical and scientific terms have same meanings as commonly understood by those having ordinary skills in the art. Terms used in the specification of the present disclosure are only for descriptive purposes and are not intended to limit the present disclosure. A term of “and/or” includes any and all combinations of one or more related items described.

According to embodiments of the present disclosure, there is provided a battery safety alert system for detecting whether the battery is held securely in place. The battery safety alert system detects a status of fixation of the battery through a detection device. For example, one of the battery and a battery mounting member is provided with an engagement mechanism, and the other is provided with a matching mechanism. The engagement mechanism engages with the matching mechanism, so as to fix the battery to the battery mounting member.

The detection device can detect the status of fixation of the battery using one of various manners. For example, in some embodiments, the detection device may detect relative position information of the engagement mechanism and the matching mechanism, and determine whether the engagement mechanism is fully engaged with the matching mechanism according to the relative position information of the engagement mechanism and the matching mechanism, so as to ensure the battery is safely fixed to the battery mounting member. Specifically, the relative position information may be a relative separation distance between the engagement mechanism and the matching mechanism, or a staggered distance between the engagement mechanism and the matching mechanism, etc.

In some embodiments, the detection device may detect position information of the engagement mechanism, and determine whether the engagement mechanism is fully engaged with the matching mechanism according to the position information of the engagement mechanism, so as to ensure the battery is safely fixed to the battery mounting member. Specifically, the position information of the engagement mechanism can be a movement distance of the engagement mechanism, or a rotation angle of the engagement mechanism, etc.

In some embodiments, the detection device may detect relative position information of the battery and the battery mounting member, and determine whether the engagement mechanism is fully engaged with the matching mechanism according to the relative position information of the battery and the battery mounting member, so as to ensure the battery is safely fixed to the battery mounting member. Specifically, the relative position information may be a depth of the battery in the battery mounting member, or a sliding distance of the battery relative to the battery mounting member, etc.

The battery safety alert system can be provided at different devices. For example, the battery safety alert system can be provided at a battery, e.g., a smart battery, or it can be provided at a powered device, e.g., an unmanned aerial vehicle (UAV), a portable gimbal, or a remote controlling ground vehicle, or it can be provided at a charging device, e.g., a charger, or a battery management device, etc.

A prompt message generated by the battery safety alert system can be sent to a controller of the battery, a controller of the powered device, a controller of a remote control device of a powered device, or a processor of a charging device, so that the processors can perform a corresponding controlling operation.

In some embodiments, the prompt message generated by the battery safety alert system can be sent to a controller of a battery. The controller of the battery controls opening and closing of an electrical connection path or sends an alarm according to the prompt message. For example, when the battery safety alert system sends a prompt message that the battery is not securely fixed while the battery is supplying power, the controller of the battery can stop the power supply. When the battery safety alert system sends a prompt message that the battery is not securely fixed while the battery is being charged, the controller of the battery can stop the charging of the battery. When the battery safety alert system sends a prompt message that the battery is not securely fixed while the battery is being used (e.g., charging or discharging), the controller of the battery controls an alarm device to send an alarm, e.g., controlling an alarm light to emit light, controlling a speaker to emit an alarm sound, or controlling a vibrator to vibrate.

In some embodiments, the prompt message generated by the battery safety alert system can be sent to a controller of a powered device. The controller of the powered device controls a powered circuit to be disconnected, controls a power device to perform a corresponding operation, or sends an alarm according to the prompt message. For example, if a UAV is on a ground and has not taken off, and the battery safety alert system sends a prompt message that the battery is not securely fixed, the controller of the UAV can control a power system to forbit taking off, control the alarm device to send an alarm, or send the prompt message to the remote controller of the UAV. During a flight of the UAV, when the battery safety alert system sends a prompt message that the battery is not securely fixed, the controller of the UAV can control the alarm device to send an alarm or send the prompt message to the remote controller of the UAV.

In some embodiments, the prompt message generated by the battery safety alert system can be sent to a controller of a remote control device of a powered device. The controller of the remote control device generates information with controlling options to a user or sends an alarm according to the prompt message. For example, during a flight of the UAV, when the battery safety alert system sends a prompt message that the battery is not securely fixed, the controller of the remote control of the UAV can control the alarm device to send an alarm or generate control information of whether to land immediately to the user, and the user can choose whether to control the UAV to land immediately.

Embodiments of the present disclosure are described in detail below with reference to the drawings, which are only for illustrative purposes and should not be construed as limiting the present disclosure.

FIG.1shows a battery safety alert system110consistent with the disclosure. The battery safety alert system110includes a detection device111and a controller113. The detection device111is communicatively connected to the controller113, e.g., in a wired communication connection or a wireless communication connection.

As shown inFIG.2A, an engagement mechanism120engages with a matching mechanism130to fix a battery101to a battery mounting member103. The battery safety alert system110is configured to detect whether the engagement mechanism120is fully engaged with the matching mechanism130.

The detection device111can detect various movement information of the engagement mechanism. For example, in some embodiments, the detection device111may be a displacement detection device for detecting a movement distance of the engagement mechanism120. In some other embodiments, the detection device111may be an angle detection device for detecting a rotation angle of the engagement mechanism120.

The detection device111can adopt various types according to different needs. For example, in some embodiments, the detection device111detects position information of the engagement mechanism120by using a principle of a magnetoelectric effect, and the corresponding detection device111may be a Hall sensor, also referred to as a Hall detection device. In some embodiments, the detection device111detects position information of the engagement mechanism120by using a principle of a photoelectric effect, and the corresponding detection device111may be a photoelectric sensor, also referred to as a photoelectric detection device. In some embodiments, the detection device111may be a micro switch.

A position of the controller113can be set according to different needs. For example, in some embodiments, the controller113and the detection device111can be both provided at the battery101. In some embodiments, the controller113and the detection device111can be both provided at the battery mounting member103. In some embodiments, as shown inFIG.7, the controller113is provided at both of the battery101and a remote controller300, or the controller113is provided at both of the battery mounting member103and the remote controller300.

The controller113is communicatively connected to the detection device111for receiving the position information of the engagement mechanism120detected by the detection device111. The communicative connection can be wired or wireless.

The engagement mechanism120is movable relative to the matching mechanism. For example, as shown inFIG.2A, the engagement mechanism120is slidable relative to the matching mechanism130. Correspondingly, the detection device111is a displacement detection device that detects a movement distance as the position information of the engagement mechanism120.

In another embodiment, as shown inFIG.2B, the engagement mechanism120is rotatable relative to the matching mechanism130. Correspondingly, the detection device111is an angle detection device that detects a rotation angle as the position information of the engagement mechanism120.

Positions of the engagement mechanism120and the matching mechanism130can be determined according to different needs. For example, as shown inFIG.2AFIGS.2A and2B, the engagement mechanism120is provided at the battery101, and the matching mechanism130is provided at the battery mounting member103. InFIG.2C, the engagement mechanism120is provided at the battery mounting member103, and the matching mechanism130is provided at the battery101.

Specific structures of the engagement mechanism120and the matching mechanism130can be determined according to different needs. For example, as shown inFIG.2A, the matching mechanism130is provided with a slot, and the engagement mechanism120is provided with a hook that engages with the slot. The hook at the engagement mechanism120can slide into the slot to engage with the slot, or slide out to separate from the slot. InFIG.2A, the matching mechanism130is provided with a first hook, and the engagement mechanism120is provided with a second hook that engages with the first hook. The second hook at the engagement mechanism120can slide relative to the first hook to engage with or separate from the first hook. The engagement mechanism120is engaged with the matching mechanism130to fix the battery101to the battery mounting member103. When the engagement mechanism120is separated from the matching mechanism130, the battery101can be freely separated from the battery mounting member103.

A position of the detection device111can be set according to different needs. For example, in some embodiments, the detection device111can be provided at the engagement mechanism120. In some embodiments, the detection device111can be provided at the matching mechanism130. The following examples illustrate methods for detecting the movement information of the engagement mechanism120when the detection device111is provided at different positions.

In some embodiments, the detection device is provided at the engagement mechanism. With reference toFIG.2A, when the detection device111detects the movement distance of the engagement mechanism120, the detection method of the detection device111can be determined according to different needs. For example, as shown inFIG.2A, the detection device111is provided at the hook, and a value for the movement distance is preset. When the movement distance of the engagement mechanism120detected by the detection device111is greater than the preset value, it may indicate that the engagement is in place. When the movement distance of the engagement mechanism120detected by the detection device111is smaller than or equal to the preset value, it may indicate that the engagement is not in place. The controller then sends a corresponding prompt message indicating that the battery101is not fully mounted at the battery mounting member103to prompt a user to re-check and re-mount the battery101, thereby ensuring that the connection between the battery101and the battery mounting member103is safe and reliable. In some embodiments, when the engagement mechanism120is fully engaged with the matching mechanism130, the controller113may also send a prompt message indicating that the engagement is in place, to prompt the user that the battery101is mounted reliably and can be used with confidence.

In some embodiments, the detection device111is still provided at the hook, and a value for the movement distance is preset. When the movement distance of the engagement mechanism120detected by the detection device111is smaller than the preset value, it may indicate that the engagement is in place. When the movement distance of the engagement mechanism120detected by the detection device111is greater than or equal to the preset value, it may indicate that the engagement is not in place. The controller then sends a corresponding prompt message indicating that the battery101is not fully mounted at the battery mounting member103to prompt a user to re-check and re-mount the battery101, thereby ensuring that the connection between the battery101and the battery mounting member103is safe and reliable. In some embodiments, when the engagement mechanism120is fully engaged with the matching mechanism130, the controller113may also send a prompt message indicating that the engagement is in place, to prompt the user that the battery101is mounted reliably and can be used with confidence.

With reference toFIG.2B, when the detection device111detects the rotation angle of the engagement mechanism120, the detection method of the detection device111can be determined according to different needs. For example, in some embodiments, the detection device111can be provided at the engagement mechanism120that can rotate at an angle relative to the matching mechanism130. The corresponding detection device111may be an angle detection device that detects the rotation angle as the position information of the engagement mechanism120. The engagement mechanism120can be provided at the battery101, and the matching mechanism130can be provided at the battery mounting member103. Or the engagement mechanism120can be provided at the battery mounting member103, and the matching mechanism130can be provided at the battery101. When the angle between the engagement mechanism120and the matching mechanism130is smaller than a preset value, it can indicate the engagement is in place. When the angle between the engagement mechanism120and the matching mechanism130is greater than the preset value, it can indicate the engagement mechanism is separated from the matching mechanism. The controller113is communicatively connected to the detection device111for receiving the position information of the engagement mechanism120detected by the detection device111.

A specific connection method of the detection device111and the engagement mechanism120can be determined according to different needs. For example, in some embodiments, the detection device111is connected to a rotation shaft of the hook of the engagement mechanism120, and the detection device may be an angle encoder. The matching mechanism130is provided with a slot or a buckle. Two rotation angle values, a first preset angle and a second preset angle, can be preset for the detection device111. In some embodiments, the detection device111can be fixed at the engagement mechanism120and the matching mechanism130. The detection device111includes a magnet provided at a free end of the hook and a Hall sensor provided at the matching mechanism.

The hook can rotate between a position corresponding to the first preset angle and a position corresponding to the second preset angle around the rotation shaft. When the hook rotates to the potion corresponding to the first preset angle, the hook engages with the slot or the buckle, indicating that the engagement is in place. When the hook rotates to the potion corresponding to the second preset angle, the hook is separated from the slot or the buckle, indicating that the engagement is not in place. The controller113then sends a corresponding prompt message indicating that the battery101is not fully mounted at the battery mounting member103to prompt a user to re-check and re-mount the battery101, thereby ensuring that the connection between the battery101and the battery mounting member103is safe and reliable. In some embodiments, when the engagement mechanism120is fully engaged with the matching mechanism130, the controller113may also send a prompt message indicating that the engagement is in place, to prompt the user that the battery101is mounted reliably and can be used with confidence.

In some embodiments, the detection device111is provided at the matching mechanism130. When the detection device111detects the movement distance of the engagement mechanism120, the detection method of the detection device111can be determined according to different needs. For example, in some embodiments, the detection device111may be provided at a bottom of the slot or near the slot, and a value for the movement distance is preset. When the movement distance of the engagement mechanism120relative to the matching mechanism130detected by the detection device111is smaller than the preset value, it may indicate that the engagement is in place. When the movement distance of the engagement mechanism120relative to the matching mechanism130detected by the detection device111is greater than or equal to the preset value, it may indicate that the engagement is not in place. The controller then sends a corresponding prompt message indicating that the battery101is not fully mounted at the battery mounting member103to prompt a user to re-check and re-mount the battery101, thereby ensuring that the connection between the battery101and the battery mounting member103is safe and reliable. In some embodiments, when the engagement mechanism120is fully engaged with the matching mechanism130, the controller113may also send a prompt message indicating that the engagement is in place, to prompt the user that the battery101is mounted reliably and can be used with confidence.

In some embodiments, the detection device111is still provided at the bottom of the slot or near the slot, and a value for the movement distance is preset. When the movement distance of the engagement mechanism120relative to the matching mechanism130detected by the detection device111is greater than the preset value, it may indicate that the engagement is in place. When the movement distance of the engagement mechanism120relative to the matching mechanism130detected by the detection device111is smaller than or equal to the preset value, it may indicate that the engagement is not in place. The controller then sends a corresponding prompt message indicating that the battery101is not fully mounted at the battery mounting member103to prompt a user to re-check and re-mount the battery101, thereby ensuring that the connection between the battery101and the battery mounting member103is safe and reliable. In some embodiments, when the engagement mechanism120is fully engaged with the matching mechanism130, the controller113may also send a prompt message indicating that the engagement is in place, to prompt the user that the battery101is mounted reliably and can be used with confidence.

When the detection device111is provided at the matching mechanism130and detects the rotation angle of the engagement mechanism120, the position information of the engagement mechanism120detected by the angle detection device111is a rotation angle of the engagement mechanism120relative to the matching mechanism130. The matching mechanism130may be provided with a slot, and the detection device111may be provided at a bottom of the slot or at an edge of the slot. Two rotation angle values, a first preset angle and a second preset angle, can be preset for the detection device111. The hook can rotate between a position corresponding to the first preset angle and a position corresponding to the second preset angle around a rotation shaft. When the hook rotates to the potion corresponding to the first preset angle, the hook engages with the slot, indicating that the engagement is in place. When the hook rotates to the potion corresponding to the second preset angle, the hook is separated from the slot, indicating that the engagement is not in place. The controller113then sends a corresponding prompt message indicating that the battery101is not fully mounted at the battery mounting member103to prompt a user to re-check and re-mount the battery101, thereby ensuring that the connection between the battery101and the battery mounting member103is safe and reliable. In some embodiments, when the engagement mechanism120is fully engaged with the matching mechanism130, the controller113may also send a prompt message indicating that the engagement is in place, to prompt the user that the battery101is mounted reliably and can be used with confidence.

In some embodiments, the matching mechanism130is provided with a buckle and the detection device111can be provided at the buckle. Two rotation angle values can be preset as a first preset angle and a second preset angle. The hook can rotate between a position corresponding to the first preset angle and a position corresponding to the second preset angle around a rotation shaft. When the hook rotates to the potion corresponding to the first preset angle, the hook engages with the buckle, indicating that the engagement is in place. When the hook rotates to the potion corresponding to the second preset angle, the hook is separated from the buckle, indicating that the engagement is not in place. The controller113then sends a corresponding prompt message indicating that the battery101is not fully mounted at the battery mounting member103to prompt a user to re-check and re-mount the battery101, thereby ensuring that the connection between the battery101and the battery mounting member103is safe and reliable. In some embodiments, when the engagement mechanism120is fully engaged with the matching mechanism130, the controller113may also send a prompt message indicating that the engagement is in place, to prompt the user that the battery101is mounted reliably and can be used with confidence.

The battery safety alert system110can detect an engagement of one engagement mechanism120with the matching mechanism130, and can also detect engagement of a plurality of engagement mechanism120with the matching mechanism130simultaneously. With reference to a schematic diagram inFIG.3, a circuit structure is provided with two detection devices111aand111b, including two micro switches111aand111b. The two micro switches111aand111bare connected in series in the circuit and are communicatively connected to the controller113, where the communicative connection can be wired or wireless.

The two micro switches111aand111bare respectively triggered by the two engagement mechanisms120. Only when the two micro switches111aand111bare triggered simultaneously will the circuit link formed by the two micro switches111aand111bbe turned on, indicating that the two engagement mechanisms120are fully engaged simultaneously and the battery is in a relatively stable status.

In some embodiments, the battery safety alert system110may further include an alarm device communicatively connected to the controller113. The alarm device is configured to prompt a user whether the battery is mounted reliably and can be used safely.

An alarm form of the alarm device may include at least one of an image display, a sound prompt, a light-emitting display, a vibration prompt, etc. Correspondingly, the alarm device may include at least one of a display screen, a speaker, a light, or a vibrator.

A position of the alarm device can be set according to different needs. For example, the alarm device may be provided at the battery, at the powered device or the charging device, etc., or at the remote control device of the powered device.

Based on the above described battery safety alert system, the present disclosure also provides an unmanned aerial vehicle (UAV) with the battery safety alert system, which is described below with reference to the drawings.

FIGS.4A and4Bshow a UAV100consistent with the disclosure. The UAV100includes a body105, a battery101, a battery mounting member103, a battery casing107, an engagement mechanism120, a matching mechanism130, and the battery safety alert system110described in above embodiments (not shown in the figure).

The battery101further includes a battery casing107for protecting the battery101. The battery casing107is provided outside the battery101and can wrap the battery101therein.

The battery mounting member103is provided in the body105, and the battery101can be mounted at the battery mounting member103.

The engagement mechanism120may be provided at the battery101or at the battery mounting member103. Correspondingly, the matching mechanism130may be provided at the battery mounting member103or at the battery101.

FIG.4Ashows a status where the battery101and the battery mounting member103of the UAV100including the battery safety alert system110are separated. In this status, the UAV100cannot perform normal flight.FIG.4Bshows a status where the battery101and the battery mounting member103of the UAV100including the battery safety alert system110are fully fixed. In this status, the UAV100can perform normal flight.

FIG.5shows a cross-sectional view of the battery101of the UAV100. The battery101is configured to supply power to the UAV100. The engagement mechanism120is provided at the battery101, and is symmetrically arranged on the left and right sides of the battery.

FIG.6shows a three-dimensional view of the battery101, where the battery casing107is provided around the battery101to protect the battery101. The engagement mechanism120is symmetrically arranged on the left and right sides of the battery.

In some embodiments, with reference toFIG.4A, the UAV100includes above-described battery safety alert system110, the battery101, the battery mounting member103, the body105, the battery casing107, the engagement mechanism120, and the matching mechanism130.

In some embodiments, the battery mounting member103is provided at the body105. The engagement mechanism120is slidable relative to the matching mechanism130. The matching mechanism130is symmetrically arranged on both sides of the battery mounting member103, and the engagement mechanism120is also symmetrically arranged on the left and right sides of the battery101.

The matching mechanism130is provided with a slot. The engagement mechanism120includes a hook configured to engage with the slot of the matching mechanism130. The hook at the engagement mechanism120can slide into the slot to engage with the slot, or slide out to separate from the slot. The detection device111also includes two that are symmetrically provided at the hooks of the engagement mechanism120on both sides of the battery101. In some embodiments, the engagement mechanism120is slidable relative to the matching mechanism130, and the corresponding detection devices111aand111bare both displacement detection device. Specifically, the displacement detection devices111aand111bare micro switches that are arranged on both sides of the battery101and connected in series in the circuit.

In some embodiments, the position information of the engagement mechanism120is detected by the micro switches. Specifically, the position information is the detected moving distance of the engagement mechanism120on the both sides of the battery101. The micro switches111aand111bare in series in the circuit and are respectively triggered by the two engagement mechanism120. If one micro switch is off, it is indicated one corresponding engagement mechanism120is not fully engaged, in which case the battery safety alert system110prompts that the connection of the battery101is not reliable and requires the user to recheck and mount the battery101.

In some embodiments, the two micro switches connected in series are normally closed switches. If the hooks of the engagement mechanisms120on both sides do not trigger the micro switches, it is indicated that the engagement mechanism120and the matching mechanism130on both sides are fully engaged, in which case an MCU_INT detection is a high level, prompting the user that the battery101is connected reliably and a taking off or other operation of the UAV can be performed. When the hook on one side slides and triggers the corresponding micro switch, causing the corresponding micro switch to turn off, it is indicated that the engagement mechanism120and the matching mechanism130on that one side are not fully engaged, in which case the MCU_INT detection is a low level. The controller113then sends a corresponding prompt message indicating that the connection of the battery101is not reliable and needs a recheck. Similarly, when the hook on the other side slides and triggers the corresponding micro switch, causing the corresponding micro switch to turn off, it is indicated that the engagement mechanism120and the matching mechanism130on that other side are not fully engaged, in which case the MCU_INT detection is also the low level. The controller113also sends a corresponding prompt message indicating that the battery101is not securely mounted or connected reliably. If the micro switches are triggered and turned off on both sides, MCU_INT is also low level, and the controller113also sends a corresponding prompt message to prompt the user to check the connection of the battery101.

In some embodiments, the micro switch is used to detect the movement distance of the engagement mechanism120to ensure that the hook of the engagement mechanism120moves within a preset movement distance, thereby ensuring that the battery101and the battery mounting member103are tightly engaged. If it is detected that the movement distance of the hook exceeds the preset distance, the safety alert system110prompts the user to engage the battery101into place. Further, if the battery is not fully mounted before a taking off, a function of the UAV100can be restricted through a program setting, e.g., not being able to operate the UAV100to take off when the battery is not fully mounted.

In some embodiments, as shown inFIG.7, a remote controller300is provided. In some embodiments, the remote controller300can be provided as part of the UAV100.

The controller113bis wireless communicatively connected to the detection device111to receive a signal from the detection device111, and can send corresponding control information.

In some embodiments, as shown inFIG.7, the alarm device115is provided at the remote controller300. In some other embodiments, the alarm device115can be provided at the body105of the UAV100. The alarm device115is configured to prompt the user whether the battery is mounted reliably, so as to achieve a goal of using the battery safely. An alarm form of the alarm device may include at least one of an image display, a sound prompt, a light-emitting display, a vibration prompt, etc. Correspondingly, the alarm device may include at least one of a display screen, a speaker, a lamp or a vibrator.

As shown inFIG.7, the detection device is provided at the engagement mechanism120. There are two controllers113(controller1denoted by113ain the figure and controller2denoted by113bin the figure) arranged at the body105and the remote controller300, respectively. The detection device111and the controller113aprovided at the body105may be wiredly or wirelessly connected. The detection device111and the controller113bprovided at the remote controller300may be wirelessly connected.

In some embodiments, as shown inFIG.8, a UAV200includes a body205, a battery safety alert system210, a battery201, a battery mounting member203, an engagement mechanism220, a matching mechanism230, an alarm device215, and a remote controller400. A detection device is provided at the matching mechanism230. Two controllers213(controller1denoted by213ain the figure and controller2denoted by213bin the figure) are respectively provided at the body205and the remote controller400.

The alarm device215is configured to warn that the battery is not fully mounted and serves as a prompt. The alarm device215may be provided at the remote controller400or at the body205of the UAV200.

In some embodiments, the form of the alarm is image display, and the corresponding alarm device115is a display screen provided at the remote controller300. If the detection device111detects that the engagement mechanism120is not fully engaged with the matching mechanism130, the display screen of the alarm device115displays an image to prompt the user that the battery101is not fully mounted.

In some embodiments, the form of the alarm is a combination of image display and light emission, and the corresponding alarm device115includes a display screen provided at the remote controller300and a light provided at the body105. If the detection device111detects that the engagement mechanism120is not fully engaged with the matching mechanism130, the display screen provided at the remote controller300displays an image, and the light provided at the body105emits light. The two alarm devices operate simultaneously, and the user can be prompted that the battery101is not fully mounted by receiving any alarm message.

In some embodiments, the form of the alarm is a combination of light emission and vibration, and the corresponding alarm device115includes a light and a vibrator both provided at the body105. If the detection device111detects that the engagement mechanism120is not fully engaged with the matching mechanism130, the light and the vibrator provided at the body105operate simultaneously. Either by eye observing or touching the UAV100, the user can receive an alarm message to know that the battery101is not fully mounted.

Since the above-described UAV100includes the battery safety alert system100, before taking off, it can prompt the user whether the battery101is mounted reliably through the battery safety alert system. During the flight of the UAV100, if the battery101is loose, the battery safety alert system can also warn the user in time. The present disclosure can greatly improve the reliability of a battery system of the UAV100and the reliability of the connection of the battery101. A user does not need to worry about a vibration and coming off of the battery101due to not fully mounted after the UAV takes off, or the battery101becomes loose due to a vibration of the UAV100and cannot be found in time. Before the UAV100takes off or during flight, the battery safety alert system110can always send safety prompt message when the battery101is loose. If the safety prompt message appears during the flight of the UAV100, the user can safely land the UAV100by a manual operation, etc., and check the mounting status of the battery101in time after landing. This can effectively reduce an accident rate of the UAV100, reduce a crash or bomber caused by the loose of the battery, and effectively avoid a loss.
