[0029] In order to illustrate the technical solution of the present invention, a detailed description is given below in conjunction with specific drawings and embodiments.

[0030] Please also read Figures 1 to 6, an embodiment of the present invention provides a remote controller 10, including a first housing 11, a display module 12, a control module, and a wireless communication module;

[0031] The first shell 11 forms an installation accommodating cavity, and the display device and the control module are both arranged inside the first shell 11. The display device is used to display the flight status information and / or real-time images of the drone, and the wireless communication module is used to communicate data with the drone; the remote control 10 is provided with an interface for connecting a backup battery 20, and the backup battery 20 is detachably connected to the remote control 10 through the interface. When the backup battery 20 is in contact with the remote control 10, the backup battery is electrically connected to the remote control.

[0032] The first shell 11 forms a housing cavity 254 , and the display module 12 is installed in the housing cavity 254 to display the flight status information and real-time image information of the drone, so that the user can know the real-time flight status of the drone during the operation of the remote controller 10 .

[0033] The control module is used to process control instructions from the user and transmit the user's instructions to the drone through the wireless communication module, while receiving feedback information from the drone and displaying it on the display device.

[0034] The backup battery 20 is connected to the internal circuit of the remote controller 10 through an interface to ensure that the remote controller 10 can continue to work when the main battery is exhausted, ensuring uninterrupted operation.

[0035] Exemplarily, the interface includes a first electrical connection terminal 13 for electrical connection and a first locking assembly 15 for fixing the backup battery 20. The first locking assembly 15 is arranged on the back side of the first shell 11 to facilitate the disassembly, assembly and replacement of the backup battery 20. Its structural design ensures a firm connection between the backup battery 20 and the remote control 10 to avoid loosening during vibration or use.

[0036] For example, the first locking component 15 can be in the form of a locking groove or a block 251, and cooperate with a corresponding component (i.e., the second locking component 25) on the backup battery 20 to form a firm fixing structure. Specifically:

[0037] When the first locking component 15 is a locking groove, the second locking component 25 is a block 251 that cooperates therewith. When the backup battery 20 is installed, the block 251 slides into the locking groove along a predetermined path and is clamped in the groove, so that the backup battery 20 is firmly installed on the back of the first shell 11. The inner wall of the locking groove can be designed to be concave and convex or provided with a limiting step to increase the friction between the locking groove and the block 251 to ensure that it does not loosen under vibration conditions. The block 251 can be easily inserted and stably fixed in the locking groove, and when disassembled, the block 251 can be removed from the groove through a certain unlocking operation.

[0038] When the first locking component 15 is a block 251, the second locking component 25 is a locking groove that matches the block 251. When installing the backup battery 20, the locking groove is aligned with the block 251 and a force is applied to push it, so that the groove and the block 251 are combined. In order to improve the firmness of the installation. The edge of the locking groove can be designed to be slightly inwardly curved to prevent the battery from accidentally falling off due to gravity. When disassembling, the user can disengage the block 251 through the locking groove.

[0039] Exemplarily, the first locking component 15 is a locking groove, which is located on the back or side of the first shell 11 and is used to cooperate with the second locking component 25 on the backup battery 20 to achieve stable installation and removal of the backup battery 20.

[0040] Specifically, the first locking assembly 15 has a certain depth and width so as to securely receive the second locking assembly 25 on the backup battery 20. The shape and size of the first locking assembly 15 are precisely designed to ensure that the backup battery 20 can be smoothly aligned and fully embedded in the slot when inserted, providing sufficient mechanical support to prevent the backup battery 20 from loosening or falling off during use.

[0041] The second locking component 25 of the backup battery 20 is designed to cooperate with the first locking groove, usually a block 251, a protrusion or a hook-shaped component. When the backup battery 20 is inserted into the first housing 11, the second locking component 25 (block 251 or protrusion) will perfectly fit with the first locking component 15, ensuring that the backup battery 20 is firmly fixed in the first housing 11. This structure not only prevents the backup battery 20 from accidentally falling off, but also provides stable physical contact to ensure that the electrical contact between the battery and the circuit connection terminal is not disturbed.

[0042] In order to facilitate the installation and removal of the backup battery 20, the second locking component 25 is usually equipped with an elastic design, such as a spring 253 and a block 251. These designs can make the backup battery 20 easily slide into the first locking component 15 during installation, and at the same time, during removal, the elastic component will pop open or loosen through slight pressure or push-pull action, allowing the user to smoothly remove the backup battery 20. This structure optimizes the user experience and avoids the problem of requiring too much force to install or remove the backup battery 20.

[0043] In addition, in order to ensure the stability of the backup battery 20 in extreme environments, the materials used for the first locking component 15 and the second locking component 25 have strong durability and anti-aging properties, and can withstand long-term plugging and pulling and vibration, ensuring that good locking performance can still be maintained under high-intensity usage environments.

[0044] The cooperation between the first locking component 15 (locking groove) and the second locking component 25 (block 251 or protrusion) not only ensures the stable installation of the backup battery 20, but also enables the backup battery 20 to be quickly and conveniently removed when needed, thereby meeting the reliability and convenience requirements of the remote control 10 in long-term use.

[0045] Exemplarily, the backup battery 20 comprises a second housing 21, a main battery 22, and a battery cover 23. The second housing 21 comprises at least one accommodating cavity 254, and the accommodating cavity 254 is used to accommodate and install the second locking assembly 25. A baffle 255 is disposed in the accommodating cavity 254, and a guide hole is provided on the baffle 255 to guide the movement of the locking assembly and ensure that the assembly is properly aligned during installation.

[0046] The second locking assembly 25 includes a first guide shaft 252, a block 251 and a spring 253. The block 251 and the first guide shaft 252 are designed as one body. The end of the block 251 away from the baffle 255 passes through the corresponding hole of the second shell 21, so that the user can press the block 251 to separate the backup battery 20. The design is intended to ensure the stable connection between the backup battery 20 and the first shell 11 and the convenience of battery removal. Specifically, the first guide shaft 252 passes through the guide hole in the accommodating cavity 254 and is firmly installed in the accommodating cavity 254, ensuring that the block 251 can move freely in the accommodating cavity 254 without deviating from the predetermined track. The setting of the guide hole allows the block 251 to remain stable when sliding on the guide shaft without getting stuck or offset.

[0047] The block 251 is the core part of the second locking assembly 25. The block 251 is integrally arranged with the first guide shaft 252. The first guide shaft 252 passes through the spring 253 and moves along the guide hole, so that the block 251 can slide freely in a certain direction. One end of the block 251 cooperates with the first locking assembly 15 of the backup battery 20, and the first guide shaft 252 is connected to the spring 253. The spring 253 provides the restoring force of the block 251 through its elastic force. When the backup battery 20 is inserted into the accommodating cavity 254, the block 251 is compressed and moves toward the other end of the guide shaft, so that the block 251 can enter the locking groove to achieve a fixed connection. The function of the spring 253 ensures that the block 251 can automatically return to its original position, and after the backup battery 20 is installed, the backup battery 20 is kept stable and not loose.

[0048] When the user needs to remove the backup battery 20, the user only needs to apply slight pressure, and the block 251 will be compressed under the reaction force of the spring 253 and move out of the locking groove, thereby releasing the backup battery 20. Due to the presence of the first guide shaft 252, the block 251 can move smoothly along a predetermined track, thereby avoiding the block 251 from getting stuck during the removal process, thereby improving the convenience of removal.

[0049] In addition, to ensure the stability of the locking mechanism in long-term use, the surfaces of the first guide shaft 252 and the clamping block 251 are treated with wear-resistant materials, which can effectively reduce the wear caused by frequent plugging and unplugging and extend the service life. The spring 253 is made of high-elastic steel to ensure that it can still maintain sufficient elasticity after long-term use, so as to ensure that the backup battery 20 can be stably and firmly fixed in the first housing 11.

[0050] In summary, by designing the cooperation of the accommodating cavity 254, the baffle 255, the guide hole, the guide shaft, the block 251 and the spring 253, the locking mechanism ensures a firm connection between the backup battery 20 and the first shell 11, while also providing a convenient disassembly mechanism, allowing the user to smoothly replace the backup battery 20 during operation without affecting the safety and stability of the battery.

[0051] Specifically, the first locking component 15 is a locking groove, which is usually located on the back of the first housing 11 and is designed to be a groove suitable for the card block 251 to be embedded. The size, depth and width of the locking groove are precisely designed to accommodate the card block 251 on the backup battery 20 and ensure that the card block 251 can be smoothly inserted into the locking groove during the installation process. When the card block 251 is fully inserted into the locking groove, physical contact will be generated between the card block 251 and the locking groove to form a firm connection, preventing the backup battery 20 from loosening or falling off due to vibration or external force during use.

[0052] The clamping block 251 is a fixed component that cooperates with the backup battery 20, and is usually designed to have an elastic or movable structure. Its shape matches the locking groove, and it can automatically engage with the edge of the locking groove when inserted, ensuring that the backup battery 20 is firmly fixed on the first housing 11. The clamping block 251 can be a spring 253 clamping block 251, a movable clamping block 251 or other similar structures, with sufficient elasticity and strength to ensure that a stable locking function can be provided even in the case of frequent plugging and unplugging.

[0053] During the disassembly process, the user only needs to apply appropriate pressure or pull the backup battery 20, and the block 251 will pop out from the locking slot under the elastic action, thereby releasing the backup battery 20. This design makes the disassembly operation of the backup battery 20 very simple and does not require the use of external force tools, thereby improving the user's operating experience.

[0054] The first electrical connection terminal 13 is located on the first side of the first housing 11 and is arranged in the direction of the backup battery 20, and is arranged corresponding to the electrical connection terminal of the backup battery 20 to achieve electrical connection. When the backup battery 20 is inserted into the first locking assembly 15, the first electrical connection terminal 13 automatically contacts and docks, thereby achieving electrical connection between the backup battery 20 and the internal circuit of the remote control 10. The first electrical connection terminal 13 adopts an elastic contact design to ensure reliable connection in a vibration environment.

[0055] Exemplarily, a first groove 16 is provided on the first side of the first housing 11, and the first groove 16 is designed for inserting and installing the backup battery 20, and ensures reliable electrical connection between the backup battery 20 and the first electrical connection terminal 13 of the remote control 10. The provision of the first groove 16 not only facilitates the disassembly and assembly of the backup battery 20, but also optimizes the plugging and unplugging stability of the battery, so that the user can easily replace the backup battery 20.

[0056] The structure of the first groove 16 includes an open end and an inner wall guide groove, the shape and size of which match the shape of the backup battery 20, so as to facilitate smooth insertion of the battery and prevent looseness. The guide groove can be designed to be a slight tilt angle or curved surface to guide the backup battery 20 to automatically align with the position of the first electrical connection terminal 13 during the insertion process, thereby ensuring the precise positioning of the contact point during the insertion process.

[0057] During the process of inserting the first protrusion 24 of the backup battery 20 into the first groove 16, the second electrical connection terminal 27 on the backup battery 20 gradually contacts and presses the first electrical connection terminal 13 to form a stable electrical connection. In order to improve the stability of the connection, the first electrical connection terminal 13 adopts an elastic contact design, which can produce a slight elastic squeeze when the battery is inserted, so that vibration and displacement can be effectively absorbed, ensuring that the battery and the terminal always maintain good contact. After the backup battery 20 is inserted into place, its electrical connection terminal will firmly contact the first electrical connection terminal 13, completing the electrical connection with the internal circuit of the remote control 10.

[0058] Exemplarily, a first electrical connection terminal 13 for achieving electrical connection is disposed in the first groove 16, and the terminal is composed of a plurality of independent metal contacts, and can form a reliable multi-point electrical connection with the second electrical connection terminal 27 of the backup battery 20. These metal contacts are arranged along the inside of the first groove 16, and are elastically designed so that they generate a slight pressing force when contacting the backup battery 20, so as to ensure the stability of the conductive performance.

[0059] For example, the backup battery 20 is provided with an independent charging interface 28, which can supply power to external devices while the backup battery 20 is connected to the remote control 10, further expanding the application scope of the backup battery 20. The charging interface 28 is located on the side or bottom of the second housing 21 and supports compatibility with common USB or Type-C interfaces, so that external devices such as mobile phones, tablets, etc. can be easily connected.

[0060] The charging interface 28 is connected to the circuit system inside the backup battery 20, and has bidirectional charging protection and current management functions, ensuring that the backup battery 20 will not affect the normal operation of the remote control 10 when providing power to external devices. The current management module will intelligently allocate the power supply priority according to the power requirements of the remote control 10 and external devices, thereby ensuring the power supply stability of the remote control 10, which can allow the user to use the backup battery 20 as an emergency power supply in an emergency to meet the collaborative power supply requirements of multiple devices.

[0061] Exemplarily, a plurality of second grooves 14 or second protrusions are provided on the first side of the first shell 11 of the remote control 10, and these second grooves 14 or second protrusions are designed to cooperate with the third protrusion 26 or third groove of the battery cover 23 of the backup battery 20, so that the backup battery 20 can be firmly and stably attached to the first side of the first shell 11.

[0062] Specifically, the second groove 14 and the third protrusion 26 can form a mechanical locking structure through geometric design. The second groove 14 is generally a concave groove structure with a certain depth and width, which is used to accommodate the third protrusion 26 on the backup battery 20. Through this concave-convex matching structure, the backup battery 20 can be firmly embedded in the first side of the remote control 10 to prevent the backup battery 20 from falling off due to external force or vibration.

[0063] In order to improve the user experience, the surfaces of the second groove 14 and the third protrusion 26 can be made of certain friction materials or anti-slip treatments, such as rubber, to further enhance the contact force between the backup battery 20 and the remote control 10 and reduce sliding or loosening caused by insufficient friction.

[0064] In summary, the matching structure of the second groove 14 and the third protrusion 26 can not only ensure a stable connection between the backup battery 20 and the first shell 11, but also effectively enhance the shock resistance of the backup battery 20, and prevent the battery from loosening or falling off due to external vibration or operational errors. This design improves the reliability of the remote control 10 and the convenience of user operation. Exemplarily, the control module includes a power management component and a switching switch, which work together to ensure that the remote control 10 can smoothly switch between the main battery 22 and the backup battery 20 to provide uninterrupted power support.

[0065] The power management component 30 is mainly responsible for monitoring the power status of the main battery 22. The component uses a power sensor and a voltage detection circuit to track the remaining power of the main battery 22 in real time and determine whether to activate the backup battery 20 through control logic. When the power of the main battery 22 is lower than the preset threshold or is close to being exhausted, the power management component will immediately issue a command to notify the switch to start the power switching mechanism.

[0066] The switching switch 40, as the core control element of power switching, has the characteristic of fast response. When receiving the switching command issued by the power management component, the switching switch immediately switches the power supply path between the main battery and the backup battery 20 to provide power for the remote control. The switching switch adopts a low-impedance electronic switch or MOSFET design to ensure the smooth flow of current during the power switching process and avoid power interruption or voltage fluctuation. The switching switch has an automatic reset function. When the power of the main battery returns to normal level and is reconnected to the power supply, the switching switch can switch back to the main battery, continue to use the main battery for power supply first, and extend the service life of the backup battery 20.

[0067] In order to improve the reliability of the control module, the power management component also has current regulation and temperature monitoring functions. During the power switching process, the power management component will adjust the switching current in real time to prevent excessive current from impacting the circuit of the remote control 10. In addition, through the temperature monitoring module, the system can switch to the backup battery 20 when the battery temperature rises abnormally, avoiding the normal operation of the remote control 10 due to overheating of the main battery; it ensures that when the main battery of the remote control 10 is insufficient or encounters an emergency, it can automatically and smoothly switch to the backup battery 20 to achieve uninterrupted power supply, so that the user will not be disturbed by battery replacement or insufficient power during operation. At the same time, the automatic switching design extends the actual standby time of the backup battery 20, and the main battery can be used first after the main battery recovers, further improving the overall power supply efficiency and user experience of the device.

[0068] In addition, to ensure the safety of users, the charging interface 28 of the backup battery 20 has overload protection and short circuit protection functions. When the current of the external device exceeds the safety threshold of the backup battery 20, the charging interface 28 will automatically cut off the power supply to prevent battery loss or overheating. At the same time, the backup battery 20 has a charging status indicator light, through which users can understand the current power supply status, including the remaining power of the backup battery 20 and the external power supply status.

[0069] By setting up this charging interface 28, the backup battery 20 can not only provide long-lasting power support for the remote control 10, but also can be used as a portable power source to charge other electronic devices, making the overall application scenarios of the device more diversified.

[0070] Exemplarily, the power management component 30 of the present invention also includes a backup battery circuit 31 and a main battery circuit 32. The backup battery circuit 31 includes a backup battery input terminal VBAT1+ and a backup battery negative electrode contact GND1, which are respectively connected to the positive and negative electrodes of the backup battery. The positive electrode VBAT1+ of the backup battery passes through filter capacitors C1 and C2 to provide smoothing of the backup battery voltage. The combination of C1 and C2 realizes double filtering: C1 (larger capacitance value) smoothes low-frequency voltage fluctuations, and C2 (smaller capacitance value) eliminates high-frequency spikes. The filtered voltage is divided by resistor R3, and the backup battery is enabled or disabled through the first switching switch 41 (Q1), which adapts to the system's flexible deployment requirements for the backup power supply; C4 and C5 provide secondary filtering of the load-end voltage to ensure the smoothness of the output voltage and guarantee the operation of subsequent circuits.

[0071] The main battery input terminal VBAT2+ and the negative ground terminal GND2 are connected to the positive and negative electrodes of the main battery. The positive electrode VBAT1+ of the main battery passes through the filter capacitors C6 and C7 to provide smoothing of the backup battery voltage. The second switching switch 42 (Q2) enables or disables the main battery. The positive electrode voltage of the main battery enters the second switching switch 42 after filtering. When the main battery power supply demand is activated, the control circuit turns on Q2 through the gate drive signal, and the main battery current flows to the load. The output filter capacitor smoothes the voltage to ensure the stability of the load voltage.

[0072] The power management component 30 also includes a backup battery driving circuit, which includes a driving circuit EN1 for controlling the backup battery, a first resistor network, and a first bipolar transistor. The first resistor network includes resistors R3 and R4, and the first bipolar transistor includes a PNP bipolar transistor Q4 and a PNP bipolar transistor Q5. When EN1 provides a low-level signal, the base voltage of the corresponding PNP transistor (such as Q5) is pulled down to turn it on. After the transistor is turned on, the gate drive resistor (R13) directly transfers the battery voltage to the gate of the MOSFET, pulls down the gate voltage, and turns on the first switching switch 41 (Q1).

[0073] The power management component 30 also includes a main battery driving circuit, and the backup driving circuit includes a driving circuit EN2 for controlling the backup battery, a second resistor network, and a second bipolar transistor. The second resistor network includes resistors R16 and R17, and the second bipolar transistor includes a PNP bipolar transistor Q6 and a PNP bipolar transistor Q7. When EN2 provides a low-level signal, the base voltage of the corresponding PNP transistor (such as Q7) is pulled down to turn it on. After the transistor is turned on, the gate driving resistor (R19) directly transfers the battery voltage to the gate of the MOSFET, pulls down the gate voltage, and turns on the second switching switch 42 (Q2).

[0074] When there is no control signal input to EN1 and EN2, the circuit defaults to the built-in battery power supply. When the external battery is inserted and meets the voltage requirements, the backup battery positive electrode VBAT1+ turns on the first switch Q1 and the second switch Q2, and the current reaches the output end through D1, automatically switching to the backup battery power supply.

[0075] The controller detects the voltage levels of the backup battery (VBAT1) and the main battery (VBAT2) to determine whether the batteries have the power supply capability. The priority of the backup battery and the main battery is determined by the logic control signals (EN1 and EN2). When the backup battery control signal EN1 is low, the backup battery switching circuit is turned on and the backup battery supplies power. When EN1 is high, the backup battery switching circuit is turned off and the backup battery stops supplying power. When the main battery control signal EN2 is low, the main battery switching circuit is turned on and the main battery supplies power. When EN2 is high, the main battery switching circuit is turned off and the main battery stops supplying power.

[0076] Initial state (main battery gives priority to power supply) By default, the main battery control signal EN2 is at a low level, the main battery supplies power, the backup battery circuit is turned off, and the backup battery control signal EN1 is at a high level. When the main battery voltage is lower than the set threshold or the main battery is disconnected, the external control circuit pulls up EN2, the main battery control signal EN2 is at a high level, and the main battery power supply path is turned off (the second switch Q2 is turned off). At the same time, EN1 is pulled down (EN1 is at a low level), so that the first switch 41 of the backup battery power supply path is turned on (Q1 is turned on). The backup battery is connected to the load through the first switch 41 to provide current to the load. When the main battery voltage recovers to above the set threshold, the external control circuit pulls down EN2, EN2 is at a low level, the main battery power supply path is turned on (the second switch 42 is turned on), and at the same time, EN1 is pulled up, and the backup battery power supply path is turned off (the first switch 41 is turned off). The main battery takes over the power supply task again, and the backup battery enters the standby state.

[0077] Through the logic signal control of EN1 and EN2, fast switching between the backup battery and the main battery is achieved to ensure uninterrupted power supply to the load. The battery has priority in power supply. The backup battery is only connected when the main battery is insufficient, which extends the service life of the backup battery. The fast turn-on and turn-off of the MOSFET reduces the voltage spike during the switching process and protects the load and battery.

[0078] The above descriptions are merely optional embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
