[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0045] An embodiment of the present application provides an electronic device, referring to Figure 1 As shown, the electronic device includes: a shooting host 11 and an expansion module 12; wherein:

[0046] A shooting host 11 is provided with an image sensor for collecting images;

[0047] In the embodiment of the present application, the image sensor may be an image acquisition unit for performing image acquisition, for example, may be a camera or a lens assembly.

[0048] The expansion module 12 is provided with an expansion module battery. The expansion module 12 is also provided with:

[0049] An electrical connection part, used for electrically connecting to a shooting host;

[0050] Display screen, used to preview the images captured by the shooting host;

[0051] A presence detection module, used to output a presence signal when the electrical connection portion is electrically connected to the shooting host;

[0052] The interactive module is used to output a power-on signal when triggered;

[0053] The control component is connected to the expansion module battery, the interaction module and the presence detection module. When the control component receives the presence signal and the power-on signal, and detects that the remaining power of the expansion module battery is less than the first power threshold, the control component controls the expansion module battery to charge the shooting host 11 through the electrical connection part, and does not light up the display screen.

[0054] In the embodiment of the present application, the expansion module battery can be used to provide working power for the expansion module, and can also be used to provide power for the shooting host, thereby realizing the charging operation of the shooting host.

[0055] The electrical connection part may be a charging interface used by the expansion module to charge the shooting host.

[0056] The presence detection module can be used to detect changes in the signal when the main camera is electrically connected to the electrical connection part, such as changes in the high and low levels. In this way, the presence signal can be a corresponding high-level signal or a corresponding low-level signal. The presence detection module can be a contact sensing device or a non-contact sensing device. When the presence detection module is a contact sensing device, it can be, for example, a current detection circuit, a pressure sensor, etc. When the presence detection module is a non-contact sensing device, it can be, for example, a Hall sensor, a micro switch, an infrared sensor, a capacitive sensor, etc.

[0057] The interactive module may be a module for the user to perform touch operations on the expansion module. In some application scenarios, the interactive module may be some shortcut keys set on the expansion module, such as a power-on key, a power-off key, etc. It should be noted that the interactive module may be a physical shortcut key or a virtual shortcut key. In this way, when the power-on key is triggered, the expansion module is controlled to switch from the power-on state to the power-off state.

[0058] The first power threshold is an empirical value of the remaining power that can protect the expansion module battery from over-discharge, obtained through a large number of experiments. In actual application, the user can set it according to experience based on the protection requirements for the expansion module battery. When the control component detects that the shooting host is connected to the electrical connection part, and detects that the interactive module is triggered to output a power-on signal, the control component detects the remaining power of the expansion module battery, and when it is determined that the remaining power is less than the first power threshold, the control component responds to the power-on signal and controls the expansion module battery to provide power to the shooting host through the electrical connection part, thereby realizing the process of charging the shooting host. However, the control component controls the display screen to continue to be in a black screen state, thereby realizing that the display screen is not lit.

[0059] The electronic device provided in the embodiment of the present application includes: a shooting host, which is provided with an image sensor for collecting images; an expansion module, which is provided with an expansion module battery, and the expansion module is also provided with: an electrical connection part, which is used to be electrically connected to the shooting host; a display screen, which is used to preview the image collected by the shooting host; an interaction module, which is used to output a power-on signal when triggered; a control component, which is connected to the expansion module battery, the interaction module and the presence detection module, and when the control component receives the presence signal and the power-on signal, and detects that the remaining power of the expansion module battery is less than a first power threshold, the control component controls the expansion module battery to charge the shooting host through the electrical connection part, and does not light up the display screen. In this way, when the shooting host is installed in the expansion module, the control component of the electronic device detects that the button on the expansion module is touched to indicate that the expansion module is turned on. When the power of the battery in the expansion module is lower than the first power threshold, the battery in the expansion module is controlled to charge the shooting host through the electrical connection part, and the display screen is not lit, so as to achieve false startup. This can reduce the situation where the display screen is constantly lit, further reduce the power consumption of the battery in the expansion cabin, solve the problem of over-discharge of the storage battery of the current electronic device affecting its service life, and propose an electronic device that does not respond to the power-on command when the remaining power is low, reduce the possibility of over-discharge of the battery of the electronic device, ensure the service life of the battery of the electronic device, and improve the use efficiency of the electronic device.

In some application scenarios, it can also be a robot device with image acquisition function, such as a sweeping robot, or a portable air-conditioning device, etc.

[0068] The control component 126 is connected to the expansion module battery 121, the interaction module 125 and the presence detection module 124. When the control component 126 receives the presence signal and the power-on signal, and detects that the remaining power of the expansion module battery 121 is less than the first power threshold, it controls the expansion module battery 121 to charge the shooting host 11 through the electrical connection part 122, and does not light up the display screen 123.

[0069] Based on the above embodiments, in other embodiments of the present application, refer to Figure 3 As shown, the control component 126 includes: a first controller a11 and a second controller a12; wherein:

[0070] The second controller a12 is connected to the expansion module battery 121 and is used to detect the remaining power of the expansion module battery 121 and output the remaining power to the first controller a11;

[0071] In other embodiments of the present application, the second controller is used to respond to operation-related instructions of the shooting host or expansion module other than the power-on and power-off operations related to the interactive module of the expansion module. After the second controller obtains the remaining power of the expansion module battery, it sends the remaining power of the expansion module battery to the first controller, so that the first controller responds to the power-on signal related to the interactive module according to the remaining power.

[0072] The first controller a11 is connected to the presence detection module 124 and the interaction module 125, and is used to control the expansion module battery 121 to charge the shooting host 11 through the electrical connection part 122 and not light up the display screen 123 when receiving the presence signal and the power-on signal and the remaining power is less than the first power threshold.

[0073] Based on the above embodiments, in other embodiments of the present application, refer to Figure 4 As shown, the control component 126 also includes: a boost circuit a13; wherein:

[0074] The boost circuit a13 has an input end connected to the expansion module battery 121, an output end connected to the electrical connection portion 122, and a controlled end connected to the first controller a11.

[0075] In an embodiment of the present application, when the first controller controls the charging of the shooting host, the first controller controls the boost circuit to boost the power output by the expansion module battery to ensure that the corresponding amount of voltage and current is provided to the shooting host, thereby ensuring that the charging process of the shooting host is in a normal state.

[0076] Based on the above embodiments, in other embodiments of the present application, refer to Figure 5 As shown, the control component 126 also includes: a battery management module a14 and a first controller a11; wherein:

[0077] The battery management module a13 is used to detect the remaining power of the expansion module battery 121;

[0078] In an embodiment of the present application, the battery management module is used to manage the battery of the expansion module, calculate and determine the remaining power of the battery of the expansion module. It should be noted that the remaining power detected by the battery management module may be lower than the actual remaining power of the battery of the expansion module. In this way, the possibility of over-discharge of the battery of the expansion module can be effectively guaranteed.

[0079] It should be noted that the battery management module is connected to the second controller, so that the second controller can obtain the remaining power of the battery of the expansion module from the battery management module.

[0080] The first controller a11 is used for, when receiving the in-position signal and the power-on signal, and when the remaining power is greater than the first power threshold and less than or equal to the second power threshold, controlling the expansion module battery 121 to charge the shooting host 11 through the electrical connection part 122, and responding to the power-on signal, controlling the display screen 123 to display a reminder message for reminding the user whether to turn on the camera;

[0081] In the embodiment of the present application, the second power threshold is an empirical value obtained based on a large number of experiments. Under this empirical value, it can be decided whether to light up the display screen based on the user's instructions, that is, the user's actual needs.

[0082] The first controller a11 is also used to control the expansion module battery 121 to charge the shooting host 11 through the electrical connection part 122 and light up the display screen 123 when receiving the in-position signal and the power-on signal and the remaining power is greater than the third power threshold; wherein the third power threshold is greater than or equal to the second power threshold.

[0083] In the embodiment of the present application, the third power threshold is an empirical value obtained based on a large number of experiments. This empirical value can ensure that the display screen is lit and working normally while powering the shooting host, and the loss of the expansion module battery is small.

[0084] Based on the foregoing embodiments, in other embodiments of the present application, the first controller a11 is further used to not respond to the power-on signal when the presence signal is not detected and the power-on signal is detected, and when it is detected that the remaining power of the expansion module battery 121 is less than or equal to the first power threshold.

[0085] In an embodiment of the present application, when the shooting host is not connected to the electrical connection part, the first controller detects that a button is pressed to execute a power-on signal. When the power-on signal is generated, if the first controller determines that the remaining power of the expansion module battery is less than or equal to the first electrical connection threshold, the first controller does not respond to the power-on signal and does not perform the power-on operation accordingly, including not controlling the discharge of the expansion module battery and not lighting up the display screen.

[0086] Based on the aforementioned embodiment, in other embodiments of the present application, the second controller a12 includes a Bluetooth control component;

[0087] The first controller a11 includes a main control component; wherein the Bluetooth control component and the main control component are connected by a serial communication bus.

[0088] In the embodiment of the present application, the Bluetooth control component may be a Bluetooth chip, which realizes management control by generating a Bluetooth signal. The main control component may be a chip with computing functions, such as a processor chip, a microprocessor chip, etc. A serial communication bus is used between the Bluetooth control component and the main control component to realize communication link.

[0089] Based on the foregoing embodiment, in other embodiments of the present application, the presence detection module 124 includes:

[0090] The first contact is connected to the control component and is used to receive a presence signal from the shooting host.

[0091] In the embodiment of the present application, the first contact point can be arranged in the area where the electrical connection part is located, for example, it can be used as a pin in the electrical connection part. The first contact point can detect whether the shooting host is accurately connected to the electrical connection part, so that when the shooting host is connected to the electrical connection part, the first contact point can detect the presence signal generated when the shooting host is accurately connected to the presence detection module.

[0092] Based on the above embodiments, in other embodiments of the present application, the electrical connection portion 122 further includes:

[0093] The second contact is connected to the control component and is used to transmit the image captured by the shooting host.

[0094] In an embodiment of the present application, the second contact is a data transmission port provided by the control component, which is capable of receiving image data collected and sent by the shooting host. In this way, the image data collected by the shooting host can be displayed on a display screen set on the expansion module to achieve preview, or stored in a storage unit included in the expansion module.

[0095] Based on the foregoing embodiment, in other embodiments of the present application, the main control component is used to detect the remaining power of the battery of the expansion module according to the first preset period;

[0096] The main control component is also used to send the remaining power to the Bluetooth control component through the serial communication bus according to the second preset period; wherein the first preset period is different from the second preset period.

[0097] In the embodiment of the present application, the first preset period and the second preset period are respectively empirical values ​​obtained from a large number of experiments, or empirical values ​​set according to user experience. The main control component periodically detects the remaining power of the expansion module battery according to the first preset period, and then periodically sends the detected remaining power to the Bluetooth control component through the serial communication bus according to the second preset period, so that the Bluetooth control component performs relevant management and control operations according to the received remaining power.

[0098] Based on the foregoing embodiment, in other embodiments of the present application, the expansion module further includes:

[0099] A receiving slot, the receiving slot is used to at least partially receive the shooting host and is mechanically detachably connected to the shooting host;

[0100] In the embodiment of the present application, the receiving slot is used to place the shooting host and is mechanically detachably connected to the shooting host. In this way, it can be ensured that the shooting host is not easy to fall off from the receiving slot, reducing the possibility of the shooting host being damaged due to falling off from the receiving slot.

[0101] The electrical connection part is fixedly arranged in the receiving groove, so that when the shooting host is located in the receiving groove, the shooting host is electrically connected to the electrical connection part.

[0102] In an embodiment of the present application, the electrical connection portion is fixedly disposed in the accommodating groove. In this way, when the shooting host is placed in the accommodating groove, the power interface of the shooting host can be connected to the electrical connection portion. In this way, the expansion module can actively charge the shooting host according to the remaining power of its own battery.

[0103] Based on the above embodiments, the present application provides a Figure 6 The partial component modules of the electronic device shown in the figure include a shooting host 11, an expansion module 12, a display screen 123 and an electrical connection part 122, wherein the electrical connection part can be a charging interface including 6 pins, wherein one pin is a first contact, or the aforementioned in-place detection module; wherein a circuit connection diagram of the expansion module 12 can be as follows Figure 7 As shown, it at least includes: a main control chip, a Bluetooth chip, a Pogo PIN with 6 pins (corresponding to the aforementioned electrical connection part), a boost module, an audio module, a display screen, a storage unit, a battery (corresponding to the aforementioned expansion module battery) and a battery management chip (corresponding to the aforementioned battery management module). Correspondingly, based on Figure 6 The electronic equipment and Figure 7The circuit connection diagram shown in FIG. 1 shows the interaction between the corresponding chip units and modules. Figure 8 As shown, the specific interaction process includes the following steps:

[0104] Step c11: The main control chip reads the remaining battery power from the battery management chip.

[0105] Among them, the main control chip reads the remaining battery power from the battery management chip through the I2C bus.

[0106] Step c12: The main control chip pushes the information to the Bluetooth chip via the Serial Peripheral Interface (SPI interface).

[0107] When the main control chip sends information to the Bluetooth chip via SPI, it can be determined by a signal on an INT pin set between the two.

[0108] Step c13: After receiving the remaining battery power, the Bluetooth chip determines whether the shooting host is connected to the charging interface. If the shooting host is connected to the charging interface, execute step c14; if the shooting host is not connected to the charging interface, execute step c18.

[0109] It should be noted that when the host is connected to the charging interface, the charging interface will generate a VBUS signal, so the expansion module can detect the VBUS signal. When the host is disconnected from the charging interface, the charging interface does not generate a VBUS signal, so the expansion module cannot detect the VBUS signal. In some application scenarios, the expansion module can be an expansion compartment.

[0110] Step c14, the Bluetooth chip determines the relationship between the remaining battery power and the preset threshold value. If the remaining battery power is less than or equal to 5%, select to execute step c15; if the remaining battery power is greater than 5% and less than or equal to 10%, select to execute step c16; if the remaining battery power is greater than 10%, select to execute step c17.

[0111] Step c15: The expansion module does not respond to the operation of the external button, but charges the shooting host.

[0112] Among them, the external buttons can be, for example, the power button and shutter button of the expansion module, and the operation of the external buttons can be, for example, the power-on operation. In this way, the expansion compartment is always in a fake power-on state, but the Bluetooth chip does not wake up the main control chip.

[0113] Step c16: The expansion module responds to the power-on operation of the external button, displays a power-on interface on the display screen to prompt the user whether to power on the device, and supplies power to the shooting host at the same time.

[0114] Step c17: The expansion module responds to the power-on operation of the external button and supplies power to the shooting host.

[0115] Exemplarily, the expansion module is explained by taking the charging box as an example. If the initial power of the charging box is less than 5%, for example, 4%, when the shooting host, such as a portable camera, is inserted into the charging box, the charging box detects the power-on operation, and the Bluetooth chip performs a fake power-on operation. If the user connects to the external power supply of the charging box at this time, the external power supply charges the charging box. After a period of time, when the power of the charging box becomes 6%, when the charging box detects the power-on operation, since the main control chip has not yet sent the power detected at this time to the Bluetooth chip, at this time, the Bluetooth chip still thinks that the power of the charging box is 4% because the power has not been updated, then the Bluetooth chip still performs a fake power-on operation at this time, ensuring that the expansion module will not have the problem of continuous restart. Assuming that the main control chip sends the detected power of the charging box to the Bluetooth chip as 7%, the Bluetooth chip detects the power-on operation, charges the portable camera, and displays a prompt message on the display screen whether to turn on the machine. Assuming that the main control chip sends the detected power of the charging box to the Bluetooth chip as 15%, the Bluetooth chip detects the power-on operation, charges the portable camera, and performs the power-on operation at the same time, such as lighting up the display screen.

[0116] It should be noted that based on Figure 7 As shown in the circuit connection diagram, after the adapter is inserted into the adapter interface of the expansion module and connected to the external power supply, the Bluetooth chip can be awakened. The Bluetooth chip enables GPIO19 through the Bluetooth signal to start the main control chip. At this time, the expansion module body enters the pseudo-start state; at the same time, GPIO8 is kept low, the switch for charging the shooting host is turned off, and the shooting host is not charged. The USB pins set at the adapter interface can be used to connect the expansion module to other electronic devices such as computer devices through a USB cable for data transmission.

[0117] The USB pin of Pogo PIN is connected to the USB_Host pin of the main control chip. In this way, the shooting host can transmit the image to be previewed to the main control chip through the USB pin of Pogo PIN, so that the main control chip can send it to the display screen for preview through the TP_I2C pin. The main control chip can output the collected audio information or power-on prompt audio information to the audio module through the LINE_OUT pin to play the corresponding audio information through the audio module.

[0118] When the aforementioned Bluetooth chip controls the battery to charge the shooting host, the Bluetooth chip detects whether the shooting host is connected to the charging interface through the DET pin of the Pogo PIN. If the Bluetooth chip detects that the shooting host is connected to the charging interface, the boost module is enabled through the EN pin, so that the power management module provides the battery power to the boost module through the VIN pin through the VBAT, and then the power is boosted according to the enable information sent by the Bluetooth chip received by the EN pin, and then a 5V voltage is provided to the Pogo PIN through the 5V pin of the boost module, so that the expansion module provides a matching amount of charging voltage for the shooting host.

[0119] Step c18: If the remaining battery power is less than or equal to 5%, no key operation will be responded to.

[0120] In this way, when the battery is low, the electronic device will not restart repeatedly, reducing the probability of over-discharge of the electronic device, especially the expansion module battery, and effectively extending the service life of the expansion module battery.

[0121] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0122] The electronic device provided in the embodiment of the present application includes: a shooting host, which is provided with an image sensor for collecting images; an expansion module, which is provided with an expansion module battery, and the expansion module is also provided with: an electrical connection part, which is used to be electrically connected to the shooting host; a display screen, which is used to preview the image collected by the shooting host; an interaction module, which is used to output a power-on signal when triggered; a control component, which is connected to the expansion module battery, the interaction module and the presence detection module, and when the control component receives the presence signal and the power-on signal, and detects that the remaining power of the expansion module battery is less than a first power threshold, the control component controls the expansion module battery to charge the shooting host through the electrical connection part, and does not light up the display screen. In this way, when the shooting host is installed in the expansion module, the control component of the electronic device detects that the button on the expansion module is touched to indicate that the expansion module is turned on. When the power of the battery in the expansion module is lower than the first power threshold, the battery in the expansion module is controlled to charge the shooting host through the electrical connection part, and the display screen is not lit, so as to achieve false startup. This can reduce the situation where the display screen is constantly lit, further reduce the power consumption of the battery in the expansion cabin, solve the problem of over-discharge of the storage battery of the current electronic device affecting its service life, and propose an electronic device that does not respond to the power-on command when the remaining power is low, reduce the possibility of over-discharge of the battery of the electronic device, ensure the service life of the battery of the electronic device, and improve the use efficiency of the electronic device.

[0123] The above description is only a preferred embodiment of the present application and is not intended to limit the protection scope of the present application.
