Description

Technical Field

[0001] This utility model relates to the field of circuit design technology, specifically to a host computer and accessories. Background Technology

[0002] With the rise of outdoor activities, people's love and connection with nature have deepened. The demand for various camping supplies is increasing daily. For example, to cope with the day-night cycle, campers often need lighting equipment; in the sweltering summer, fans are needed for cooling; and when powering small electronic devices, batteries and compatible interfaces are required. Therefore, a new type of lamp, primarily equipped with batteries, is being developed, featuring detachable accessories with various functions to meet the needs of users in different scenarios.

[0003] However, existing technologies often cannot switch between different power consumption levels and speeds for different accessories, thus making it impossible to adjust the current or voltage input to the accessories. If the power consumption of an accessory is too high, for example, if a high-speed fan is needed to blow snow in winter, too low a current or voltage will easily cause the high-speed fan to rotate too low, resulting in low snow blowing efficiency. Alternatively, if the power consumption of an accessory is too low, for example, if a hand warmer is needed to keep warm in winter, too high a current or voltage will easily cause the hand warmer to overheat, which may burn the user or even cause the device to overheat and catch fire.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0026] like Figure 1-3 As shown, this embodiment relates to a host 10 and an accessory 20, with the accessory 20 assembled on the host 10. The host 10 includes a first connection module 11, and the accessory 20 includes a second connection module 21. When the accessory 20 is assembled on the host 10, the first connection module 11 and the second connection module 21 abut against each other to electrically connect the host 10 and the accessory 20.

[0027] In some embodiments, the first connection module 11 and the second connection module 21 are both magnetic contacts, and the electrical connection between the host 10 and the accessory 20 can be achieved when they come into contact.

[0028] like Figure 1-3As shown, the host 10 includes a first connection module 11, an identification module 12, a power supply module 13, and a first control module 14. The external terminals of the first connection module 11 are connected to the external terminals of the second connection module 21 of the accessory 20. The identification module 12 is connected to the first connection module 11 to identify the identity information of the accessory 20 and output identification information corresponding to that identity information. The power supply module 13 provides power. The first control module 14 is connected to the power supply module 13, the first connection module 11, and the identification module 12. The first control module 14 receives the identification information sent by the identification module 12 and outputs a first preset power corresponding to the identification information to the first connection module 11, thereby outputting the first preset power to the accessory 20 to power its operation.

[0029] like Figure 4 As shown, the first control module 14 includes a control chip and a buck-boost circuit 141. The control chip is a synchronous buck-boost charging controller with an I2C interface, specifically model SC8815. The buck-boost circuit 141 consists of four MOSFETs and a buck-boost control circuit; the MOSFETs are specifically model AON7752. The power module 13 is connected to the control chip and the buck-boost circuit 141, and the buck-boost circuit 141 is connected to the control chip and the first connection module 11.

[0030] It should be further explained that the power module 13 supplies power to the buck-boost circuit 141. The control chip is connected to the identification module 12 via dual serial communication and receives the identity information sent by the identification module 12. The control chip is connected to the four MOSFETs in the buck-boost circuit 141, enabling the control chip to control the on / off state of the four MOSFETs, thereby controlling the buck-boost control circuit to achieve buck-boost control, which in turn controls the first preset power output of the first control module 14. The first preset power is transmitted to the first connection module 11 so that the host 10 outputs the first preset power to the accessory 20.

[0031] Specifically, the dual serial communication between the control chip and the identification module 12 is achieved through the connection of the SCL and SDA pins.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, this embodiment uses resistor identification. The identification module 12 includes a voltage identification chip 121 and a voltage divider circuit 122. The voltage divider circuit 122 includes an identification power supply 1221 and a voltage divider resistor 1222. One end of the voltage divider resistor 1222 is connected to the identification power supply 1221, and the other end of the voltage divider resistor 1222 is connected to the identification pin of the voltage identification chip 121 along with the first connection module 11. The identification information is the resistance value. The resistor with the identification information in accessory 20 is connected to the voltage divider resistor 1222 through the first connection module 11. The identification power supply 1221 provides voltage to the voltage divider resistor 1222 and the resistor with the identification information, allowing the identification pin to identify the voltage value. The voltage identification chip 121 receives the voltage value corresponding to the identification information and simultaneously sends the identification information corresponding to the identification information to the first control module 14.

[0033] It should be further noted that a protection circuit 123 is provided between the voltage identification chip 121 and the voltage divider resistor 1222. The protection circuit 123 includes a first protection resistor 1231 and a protection capacitor 1232. One end of the first protection resistor 1231 is connected to the voltage divider resistor 1222, and the other end of the first protection resistor 1231 and the protection capacitor 1232 are connected to the identification pin of the voltage identification chip 121. The other end of the protection capacitor 1232 is grounded. The first protection resistor 1231 is used to limit the current to prevent excessive current from damaging the voltage identification chip 121, and the protection capacitor 1232 is used to absorb voltage surges to protect the voltage identification chip 121 from voltage fluctuations.

[0034] Specifically, both the first connection module 11 and the second connection module 21 have 5 pins. Pins 2 of both modules are used to transmit a first preset power, and pins 1 of both modules are grounded. The voltage of the power supply 1221 is 5V. The voltage divider resistor 1222R85 has a resistance of 10kΩ. The first protection resistor 1231R81 has a resistance of 2.2kΩ. The protection capacitor 1232C68 has a capacitance of 104, or 0.1uF. The protection circuit 123 is connected to pin 17 of the voltage recognition chip 121. The voltage divider resistor 1222 is connected to pin 3 of the first connection module 11, which corresponds to pin 3 of the second connection module 21. The module 22 to be identified in accessory 20 is connected to pin 3 of the second connection module 21.

[0035] like Figure 2 As shown, the identification module 12 includes a first single serial communication chip 124. The first single serial communication chip 124 is connected to the first connection module 11 through the first communication line 125. The first single serial communication chip 124 receives identity information through the first communication line 125 and outputs identification information to the first control module 14 according to the identity information.

[0036] Specifically, the identification module 12 includes a first single serial communication chip 124. The first single serial communication chip 124 is connected to the first connection module 11 through a first communication line 125. The first single serial communication chip 124 receives identity information through the first communication line 125 and sends identity confirmation information to the first connection module 11 through the first communication line 125 based on the identity information, so as to send the identity confirmation information to the accessory 20. The accessory 20 returns identity confirmation information to the first connection module 11 based on the identity confirmation information. The identity confirmation information is sent to the first single serial communication chip 124 through the first communication line 125. The first single serial communication chip 124 outputs identification information to the first control module 14 based on the identity confirmation information.

[0037] More specifically, both the first connection module 11 and the second connection module 21 have 5 pins. Pins 2 of both the first connection module 11 and the second connection module 21 are used to transmit a first preset power, and pins 1 of both the first connection module 11 and the second connection module 21 are grounded. Pin 3 of the first connection module 11 is connected to the USAUT pin of the first single serial communication chip 124 of the identification module 12, and pin 3 of the second connection module 21 is connected to the USAUT pin of the second single serial communication chip 222 of the module to be identified in the accessory 20.

[0038] like Figure 3 As shown, the identification module 12 includes a first dual serial communication chip 126. The first dual serial communication chip 126 is connected to the first connection module 11 through a first communication line 125 and a second communication line 127. The first dual serial communication chip 126 receives identity information through the first communication line 125 and sends identity confirmation information to the first connection module 11 through the second communication line 127 based on the identity information, so as to send identity confirmation information to the accessory 20. The accessory 20 returns identity confirmation information to the first connection module 11 based on the identity confirmation information. The identity confirmation information is sent to the first dual serial communication chip 126 through the first communication line 125. The first dual serial communication chip 126 outputs identification information to the first control module 14 based on the identity confirmation information.

[0039] Specifically, both the first connection module 11 and the second connection module 21 have 5 pins. Two pins of both modules are used to transmit a first preset power, and one pin of each module is grounded. Compared to resistor identification and electronic tag identification, this embodiment adds one pin to both the first connection module 11 and the second connection module 21, resulting in 6 pins for each module. Pin 3 of the first connection module 11 is connected to the SCL pin of the first dual serial communication chip 126 of the identification module 12, and pin 6 of the first connection module 11 is connected to the SDA pin of the first dual serial communication chip 126 of the identification module 12. Pin 3 of the second connection module 21 is connected to the SCL pin of the second dual serial communication chip 225 of the module to be identified in the accessory 20, and pin 6 of the second connection module 21 is connected to the SDA pin of the second dual serial communication chip 225 of the module to be identified in the accessory 20.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the host 10 also includes a second control module 15, which is connected to the identification module 12. The second control module 15 is used to output a first adjustment signal. The identification module 12 outputs first adjustment information to the first control module 14 according to the first adjustment signal. The first control module 14 adjusts the first preset power according to the first adjustment information.

[0041] Specifically, the second control module 15 includes multiple buttons, two of which are a gear adjustment button and a power switch button.

[0042] More specifically, the gear adjustment buttons include an up button S4 and a down button S5, and the power switch button is S6. When the chip in the identification module 12 identifies the first adjustment signal output by the button, the chip establishes a dual serial communication connection with the first control module 14 through SCL and SDA, and sends the first adjustment information to the first control module 14 through this dual serial communication. The first control module 14 adjusts the first preset power according to the first adjustment information.

[0043] It should be noted that the first preset power is divided into multiple levels, such as three levels, with the initial level being the second level.

[0044] When the user presses the plus button S4, the chip recognizes the first adjustment signal output by the button S4 and sends the first adjustment information to the first control module 14. The first adjustment signal is an upward adjustment signal and the first adjustment information is an upward adjustment information. The first control module 14 increases the first preset power according to the upward adjustment information, so that the first preset power switches from the second level to the third level.

[0045] When the user presses the down button S5, the chip recognizes the first adjustment signal output by the button S5 and sends the first adjustment information to the first control module 14. The first adjustment signal is a down signal and the first adjustment information is down information. The first control module 14 down adjusts the first preset power according to the down information, so that the first preset power switches from the second gear to the first gear.

[0046] When the user presses the power switch button S6, the chip recognizes the first adjustment signal output by button S6 and sends the first adjustment information to the first control module 14. The first adjustment signal is a power-on / off signal, and the first adjustment information is also a power-on / off signal. The first control module 14 outputs or shuts down a first preset power based on the power-on / off signal, specifically determined by the current output state. When the first control module 14 is outputting the first preset power, it receives the power-on / off signal and shuts down the output of the first preset power. When the first control module 14 is not outputting the first preset power, it receives the power-on / off signal and begins outputting the first preset power. The adjustment of the first preset power is achieved by controlling the output current or voltage.

[0047] Specifically, when accessory 20 is a flashlight, handheld fan, ceiling fan, ambient light, camping light, water pump, or air pump, when the user presses the "+" button, the first control module 14 increases the first preset power by one level. When the user presses the "-" button, the first control module 14 decreases the first preset power by one level. When the user presses the "+" power switch button, the output of the first preset power is controlled or interrupted.

[0048] like Figure 3 As shown, the host 10 also includes a second control module 15, which is connected to the first control module 14. The second control module 15 is used to output a first adjustment signal, and the first control module 14 adjusts the first preset power according to the first adjustment signal.

[0049] Specifically, the second control module 15 includes multiple buttons, two of which are a gear adjustment button and a power switch button.

[0050] It should be noted that the first preset power is divided into multiple levels, such as three levels, with the initial level being the second level.

[0051] When the user presses the plus button S4, the first control module 14 recognizes the first adjustment signal output by the button S4, wherein the first adjustment signal is an upward adjustment signal. The first control module 14 adjusts the first preset power according to the upward adjustment signal, so that the first preset power switches from the second level to the third level.

[0052] When the user presses the down button S5, the first control module 14 recognizes the first adjustment signal output by the button S5, wherein the first adjustment signal is a down signal. The first control module 14 adjusts the first preset power according to the down signal, so that the first preset power switches from the second gear to the first gear.

[0053] When the user presses the power switch button S6, the first control module 14 recognizes the first adjustment signal output by button S6. This first adjustment signal is a power on / off signal. The first control module 14 outputs or shuts off a first preset power based on the power on / off signal, specifically determined by the current output state. When the first control module 14 is outputting the first preset power, receiving the power on / off signal will shut off the first preset power output. When the first control module 14 is not outputting the first preset power, receiving the power on / off signal will start outputting the first preset power. The adjustment of the first preset power is achieved by controlling the output current or voltage.

[0054] Specifically, when accessory 20 is a flashlight, handheld fan, ceiling fan, ambient light, camping light, water pump, or air pump, when the user presses the "+" button, the first control module 14 increases the first preset power by one level. When the user presses the "-" button, the first control module 14 decreases the first preset power by one level. When the user presses the "+" power switch button, the output of the first preset power is controlled or interrupted.

[0055] like Figure 3 As shown, the host 10 also includes a second control module 15, which is connected to the first control module 14. The second control module 15 is used to output a first adjustment signal. The first control module 14 outputs first adjustment information to the first connection module 11 according to the first adjustment signal, so as to send the first adjustment information to the accessory 20. The accessory 20 has multiple usage modes, and the accessory 20 switches the usage mode according to the first adjustment information.

[0056] It should be noted that after receiving the first preset power, the accessory 20 is controlled by the third control module 23 inside the accessory 20 to output the second preset power to the working module 24. The accessory 20 has multiple usage modes, and the second preset power is divided into multiple levels, such as three levels, initially at the second level.

[0057] Specifically, the first adjustment information is sent to the 5th or 4th pin of the second connection module 21 via pin 5 or pin 4 of the first connection module 11. The second control module 15 includes multiple buttons, two of which are a gear adjustment button and a power switch button.

[0058] More specifically, the gear adjustment buttons include an up button S4 and a down button S5, and the power switch button is S6. When the chip in the identification module 12 identifies the first adjustment signal output by the button, the chip establishes a dual serial communication connection with the first control module 14 through SCL and SDA, and sends the first adjustment information to the first control module 14 through this dual serial communication. The first control module 14 then sends the first adjustment information to the first connection module 11, thereby sending the first adjustment information to the accessory 20. The third control module 23 in the accessory 20 receives the first adjustment information and adjusts the second preset power according to the first adjustment information.

[0059] When the user presses the plus button S4, the chip recognizes the first adjustment signal output by button S4 and sends the first adjustment information to the first control module 14. The first adjustment signal is an up-adjustment signal, and the first adjustment information is up-adjustment information. The first control module 14 sends the up-adjustment information to the first connection module 11, which transmits it to the third control module 23 of the accessory 20. The third control module 23 adjusts the second preset power according to the up-adjustment information, switching the second preset power from the second level to the third level. The first control module 14 is connected to pin 5 of the first connection module 11, and the third control module 23 is connected to pin 5 of the second connection module 21. Thus, the up-adjustment information is sent to the third control module 23 via pins 5 of the first and second connection modules, and the third control module 23 adjusts the second preset power according to the up-adjustment information.

[0060] When the user presses the down button S5, the chip recognizes the first adjustment signal output by button S5 and sends the first adjustment information to the first control module 14. The first adjustment signal is a down signal, and the first adjustment information is down information. The first control module 14 sends the down information to the first connection module 11, which transmits it to the third control module 23 of the accessory 20. The third control module 23 down-adjusts the second preset power according to the down information, switching the second preset power from the second level to the first level. The first control module 14 is connected to pin 4 of the first connection module 11, and the third control module 23 is connected to pin 4 of the second connection module 21. This allows the down-adjustment information to be sent to the third control module 23 via pins 4 of the first and second connection modules, enabling the third control module 23 to adjust the second preset power according to the down information.

[0061] When the user presses the power switch button S6, the chip recognizes the first adjustment signal output by button S6 and sends the first adjustment information to the first control module 14. The first adjustment signal is a power-on / off signal, and the first adjustment information is also a power-on / off signal. The first control module 14 sends the power-on / off signal to the first connection module 11, which transmits it to the third control module 23 of accessory 20. The third control module 23 outputs or shuts down the second preset power based on the power-on / off signal, specifically determined by the current output state. When the third control module 23 is outputting the second preset power, it receives the power-on / off signal and shuts down the output of the second preset power. When the third control module 23 is not outputting the second preset power, it receives the power-on / off signal and begins to output the second preset power. The first preset power is adjusted by controlling the output current or voltage. The first control module 14 is connected to pin 5 of the first connection module 11, and the third control module 23 is connected to pin 5 of the second connection module 21. The first control module 14 is also connected to pin 4 of the first connection module 11, and the third control module 23 is connected to pin 4 of the second connection module 21. The power on / off signal is sent to the third control module 23 through pin 5 of the first connection module 11 and pin 5 of the second connection module 21, or through pin 4 of the first connection module 11 and pin 4 of the second connection module 21. The third control module 23 then adjusts the second preset power according to the power on / off signal.

[0062] Specifically, accessory 20 is a high-speed fan or electric screwdriver, and working module 24 is a motor. When the user presses the "+" button, the third control module 23 increases the second preset power by one level. When the user presses the "-" button, the third control module 23 decreases the second preset power by one level. When the user presses the "+" power switch button, it controls the output of the second preset power or interrupts the output.

[0063] More specifically, the third control module 23 of accessory 20 has a boost / buck circuit 141 to regulate the output voltage or current, thereby regulating the second preset power.

[0064] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the host 10 also includes a second control module 15, which is connected to the identification module 12. The second control module 15 is used to output a first adjustment signal. The identification module 12 outputs first adjustment information to the first connection module 11 according to the first adjustment signal, so as to send the first adjustment information to the accessory 20. The accessory 20 has multiple usage modes, and the accessory 20 switches the usage mode according to the first adjustment information.

[0065] It should be noted that after receiving the first preset power, the accessory 20 is controlled by the third control module 23 inside the accessory 20 to output the second preset power to the working module 24. The accessory 20 has multiple usage modes, and the second preset power is divided into multiple levels, such as three levels, initially at the second level.

[0066] Specifically, the first adjustment information is sent to the 5th or 4th pin of the second connection module 21 via pin 5 or pin 4 of the first connection module 11. The second control module 15 includes multiple buttons, two of which are a gear adjustment button and a power switch button.

[0067] More specifically, the gear adjustment buttons include an up button S4 and a down button S5, and the power switch button is S6. When the chip in the identification module 12 identifies the first adjustment signal output by the button, the chip sends the first adjustment information to the first connection module 11, thereby sending the first adjustment information to the accessory 20. The third control module 23 in the accessory 20 receives the first adjustment information and adjusts the second preset power according to the first adjustment information.

[0068] When the user presses the plus button S4, the chip recognizes the first adjustment signal output by button S4 and sends the first adjustment information to the first connection module 11, which is then transmitted to the third control module 23 of accessory 20. The first adjustment signal is an up-adjustment signal, and the first adjustment information is up-adjustment information. The third control module 23 adjusts the second preset power according to the up-adjustment information, causing the second preset power to switch from the second level to the third level. The recognition module 12 is connected to pin 5 of the first connection module 11, and the third control module 23 is connected to pin 5 of the second connection module 21, thus sending the up-adjustment information to the third control module 23 via pins 5 of the first and second connection modules 11. The third control module 23 then adjusts the second preset power according to the up-adjustment information.

[0069] When the user presses the down button S5, the chip recognizes the first adjustment signal output by button S5 and sends the first adjustment information to the first connection module 11, which is then transmitted to the third control module 23 of accessory 20. The first adjustment signal is a down signal, and the first adjustment information is down information. The first control module 14 sends the down information to the first connection module 11. The third control module 23 down-adjusts the second preset power according to the down information, switching the second preset power from the second level to the first level. The recognition module 12 is connected to pin 4 of the first connection module 11, and the third control module 23 is connected to pin 4 of the second connection module 21. This allows the down-adjustment information to be sent to the third control module 23 via pins 4 of the first and second connection modules 11, thereby enabling the third control module 23 to adjust the second preset power according to the down information.

[0070] When the user presses the power switch button S6, the chip recognizes the first adjustment signal output by button S6 and sends the first adjustment information to the first connection module 11, thereby sending a power-on / off signal to the third control module 23 of accessory 20. The first adjustment signal and the first adjustment information are both power-on / off signals. The third control module 23 outputs or shuts down the second preset power according to the power-on / off signal, specifically determined by the current output state. When the third control module 23 is outputting the second preset power, it receives the power-on / off signal and shuts down the output of the second preset power. When the third control module 23 is not outputting the second preset power, it receives the power-on / off signal and starts outputting the second preset power. The first preset power is adjusted by controlling the output current or voltage. The identification module 12 is connected to pin 5 of the first connection module 11, and the third control module 23 is connected to pin 5 of the second connection module 21. The identification module 12 is also connected to pin 4 of the first connection module 11, and the third control module 23 is connected to pin 4 of the second connection module 21. The power on / off signal is sent to the third control module 23 through pin 5 of the first connection module 11 and pin 5 of the second connection module 21, or through pin 4 of the first connection module 11 and pin 4 of the second connection module 21. The third control module 23 then adjusts the second preset power according to the power on / off signal.

[0071] Specifically, accessory 20 is a high-speed fan or electric screwdriver, and working module 24 is a motor. When the user presses the "+" button, the third control module 23 increases the second preset power by one level. When the user presses the "-" button, the third control module 23 decreases the second preset power by one level. When the user presses the "+" power switch button, it controls the output of the second preset power or interrupts the output.

[0072] More specifically, the third control module 23 of accessory 20 has a boost / buck circuit 141 to regulate the output voltage or current, thereby regulating the second preset power.

[0073] like Figure 1-3 As shown, the host 10 also includes a display module 16, which is connected to the identification module 12. The display module 16 is used to receive the display signal sent by the identification module 12 and display accordingly based on the display signal.

[0074] Specifically, the light-emitting component of the display module 16 includes a lamp holder, a light source, and a lampshade. The lamp holder is for mounting the light source, which is connected to the identification module 12. The lampshade is fitted onto the lamp holder and is made of a light-transmitting material. The display module 16 may also include a display screen for displaying status information, including power information and the operating mode of the accessory 20.

[0075] In other embodiments, the host 10 further includes a display module 16, which is connected to the first control module 14. The display module 16 is used to receive display signals sent by the first control module 14 and display accordingly based on the display signals.

[0076] Specifically, the display module 16 is a light-emitting component, which includes a lamp holder, a light source, and a lampshade. The lamp holder is for mounting the light source, the light source is connected to the first control module 14, and the lampshade is fitted onto the lamp holder and is made of a light-transmitting material. The display module 16 may also include a display screen, which is used to display status information, including power information, the working mode of accessory 20, and other information.

[0077] In some embodiments, the display module 16 is a power indicator light. A long press of the power switch button allows the power indicator light to display the remaining battery level of the power module 13. In this embodiment, the display method is as follows: five LEDs are used. The more LEDs that are lit, the more battery power is available. When fully charged, all five LEDs are lit. When the battery level is low (less than 5%), only one LED flashes, and the others are off. In other embodiments, only one LED is used. Different colors of this LED indicate different battery levels of the power module 13. For example, a green LED represents 70% or more battery power, a yellow LED represents 21%-69% battery power, and a red LED represents 20% or less battery power.

[0078] It should be added that multiple LED beads can also serve as gear indicator lights. When the gear adjustment button is adjusted to different gears, the corresponding LED beads will light up.

[0079] like Figure 1-3 As shown, this embodiment of the present invention provides an accessory 20, which is assembled into the aforementioned host 10. The accessory 20 includes a second connection module 21, a module to be identified 22, a third control module 23, and a working module 24. The second connection module 21 is connected to the host 10, specifically to the host 10's first connection module 11. The module to be identified 22 is connected to the second connection module 21 and is used to output identity information, which is output to the host 10 through the second connection module 21. The third control module 23 is connected to the second connection module 21 and is used to receive a first preset power output from the host 10 and output a second preset power. The working module 24 is connected to the third control module 23 and is used to receive the second preset power, enabling the working module 24 to operate normally. The host 10 receives the identity information and outputs the first preset power corresponding to the identity information to the second connection module 21.

[0080] Specifically, the identification module 12 of the host 10 receives identity information and sends corresponding identification information to the first control module 14 of the host 10 according to the identity information. The first control module 14 outputs the corresponding first preset power to the first connection module 11 of the host 10 according to the identification information. The first connection module 11 transmits the first preset power to the second connection module 21. The third control module 23 receives the first preset power transmitted by the second connection module 21 and outputs the second preset power to the working module 24 for the working module 24 to work.

[0081] like Figure 1 As shown, the identification module 22 includes an identification resistor 221. One end of the identification resistor 221 is connected to ground, and the other end of the identification resistor 221 is connected to the second connection module 21. The identification information is the resistance value of the identification resistor 221. The identification resistor 221 is used to provide identification information so as to output the identification information to the host 10.

[0082] Specifically, one end of the resistor to be identified 221 is connected to ground, and the other end of the resistor to be identified 221 is connected to one end of the voltage divider resistor 1222 of the identification module 12 through the second connection module 21 and the first connection module 11. Both are connected to the identification pin of the voltage identification chip 121. The other end of the voltage divider resistor 1222 is connected to the identification power supply 1221 to form a voltage divider circuit 122, so that the voltage identification chip 121 obtains a voltage value. The voltage identification chip 121 outputs corresponding identity information according to the voltage value. The first control module 14 receives the identity information and outputs a first preset power to the first connection module 11. The first connection module 11 outputs the first preset power to the accessory 20, thereby enabling the host 10 to identify the accessory 20 and output the power required by the accessory 20.

[0083] More specifically, the voltage identification chip 121 outputs identification information based on the voltage value. Since the resistance value of the resistor to be identified 221 is fixed, the voltage value obtained by the voltage identification chip 121 is fixed, and the identification information output by the voltage identification chip 121 is fixed. Consequently, the first control module 14 outputs a fixed first preset power based on the identification information. When different components 20 require the same power, the resistance values ​​of the resistors to be identified 221 are the same, and the output identification information is the same. Therefore, the first preset power output by the first control module 14 to the first connection module 11 is the same. Thus, when two components 20 require the same power, the resistance values ​​of the two resistors to be identified 221 can be the same. When two components 20 require different power, the resistance values ​​of the two resistors to be identified 221 are different, and the first preset power is set according to the power required by the component 20. This enables the identification module 12 to identify the resistor to be identified 221 and output identification information, the first control module 14 to receive the identification information and output the first preset power to the first connection module 11, and the first connection module 11 to output the first preset power to the component 20. This enables the host 10 to identify the component 20 and output the power required by the component 20.

[0084] In the embodiment employing resistor identification, when accessory 20 is a high-speed fan, the first preset power is 70W, the corresponding voltage is 14V, and the current is 5A. The resistance of the resistor to be identified 221 is 2.4KΩ, and the voltage identification chip 121 obtains a voltage value of 0.97V.

[0090] When accessory 20 is used as an ambient light, the first preset power has five levels: 3W / 3.5W / 4W / 4.5W / 5W, corresponding to voltages of 3V / 3.5V / 4V / 4.5V / 5V and a current of 1A. The resistance of the resistor to be identified, 221, is 24KΩ, and the voltage identification chip 121 receives a voltage value of 3.33V.

[0091] When accessory 20 is a camping light, the first preset power has five levels: 3W / 3.5W / 4W / 4.5W / 5W, corresponding to voltages of 3V / 3.5V / 4V / 4.5V / 5V and current of 1A. The resistance of the resistor to be identified, 221, is 24KΩ, and the voltage identification chip 121 receives a voltage value of 3.33V.

[0092] When accessory 20 is an alarm module, the first preset power is 15W, the corresponding voltage is 5V, and the current is 3A. The resistance of the resistor to be identified 221 is 30KΩ, and the voltage identification chip 121 receives a voltage value of 3.75V.

[0093] When accessory 20 is a hand warmer, the first preset power is 15W, the corresponding voltage is 5V, and the current is 3A. The resistance of the resistor to be identified 221 is 30KΩ, and the voltage identification chip 121 receives a voltage value of 3.75V.

[0094] When accessory 20 is a car air pump, the first preset power is 70W, the corresponding voltage is 14V, and the current is 5A. The resistance of the resistor to be identified 221 is 2.4KΩ, and the voltage identification chip 121 receives a voltage value of 0.97V.

[0095] When accessory 20 is a water pump, the first preset power has five levels: 24W / 27W / 30W / 33W / 36W, corresponding to voltages of 8V / 9V / 10V / 11V / 12V and current of 3A. The resistance of the resistor to be identified, 221, is 43KΩ, and the voltage identification chip 121 receives a voltage value of 4.06V.

[0096] When accessory 20 is an electric screwdriver, the first preset power is 10.8W, the corresponding voltage is 3.6V, and the current is 3A. The resistance of the resistor to be identified 221 is 1.5KΩ, and the voltage identification chip 121 obtains a voltage value of 0.652V.

[0097] When accessory 20 is an air pump, the first preset power has five levels: 12W / 13.5W / 15W / 16.5W / 18W, corresponding to voltages of 8V / 9V / 10V / 11V / 12V and a current of 1.5A. The resistance of the resistor to be identified, 221, is 20KΩ, and the voltage identification chip 121 receives a voltage value of 3.33V.

[0098] like Figure 2 As shown, the identification module 22 includes a second single serial communication chip 222. The second single serial communication chip 222 is connected to the second connection module 21 through a third communication line 223. The second single serial communication chip 222 sends identity information to the second connection module 21 through the third communication line 223 to send the identity information to the host 10. The host 10 outputs a first preset power to the second connection module 21 according to the identity information.

[0099] Specifically, the identification module 22 includes a second single-serial communication chip 222. The second single-serial communication chip 222 is connected to the second connection module 21 via a third communication line 223. The second single-serial communication chip 222 sends identity information to the second connection module 21 via the third communication line 223 to transmit the identity information to the host 10. The host 10 sends identity confirmation information to the second connection module 21 based on the identity information, which is then transmitted to the second single-serial communication chip 222 via the third communication line 223. The second single-serial communication chip 222 receives the identity confirmation information and sends corresponding identity-confirmed information to the second connection module 21 via the third communication line 223 to transmit the identity-confirmed information to the host 10. The host 10 outputs a first preset power to the second connection module 21. Herein, the identity confirmation information corresponds to the identity information, and the identity-confirmed information corresponds to the identity confirmation information.

[0100] More specifically, when accessory 20 is assembled onto host 10, the first control module 14 outputs identification power. This identification power flows through the first connection module 11, the second connection module 21, and the third control module 23 to reach the module to be identified 22. The second single-serial communication chip 222 of the module to be identified 22 receives the identification power and outputs identity information through the third communication line 223. The identity information flows through the third communication line 223 and the first communication line 125 to reach the first single-serial communication chip 124 of the identification module 12. Specifically, the identity information flows through the second protection resistor 224, the second connection module 21, and the first connection module 11 of the module to be identified 22 to reach the first communication line 125, and through the first protection resistor 1231 of the identification module 12 to reach the first single-serial communication chip 124 of the identification module 12. The identity information is an electronic tag.

[0101] It should be further explained that the first single serial communication chip 124 of the identification module 12 outputs corresponding identity confirmation information according to the identity information. The identity confirmation information flows through the first communication line 125 and the third communication line 223 to reach the second single serial communication chip 222 of the module to be identified 22. That is, the identity confirmation information flows through the first protection resistor 1231, the first connection module 11 and the second connection module 21 of the identification module 12 to reach the third communication line 223. The identity confirmation information flows through the second protection resistor 224 of the module to be identified 22 to reach the second single serial communication chip 222 of the module to be identified 22.

[0102] It should be further explained that the second single serial communication chip 222 of the identification module 22 outputs the corresponding identity confirmation information according to the identity confirmation information. The identity confirmation information passes through the second protection resistor 224 of the identification module 22, the second connection module 21, the first connection module 11 and the first protection resistor 1231 of the identification module 12 to reach the first single serial communication chip 124 of the identification module 12.

[0103] It should be further explained that the first single serial communication chip 124 outputs the corresponding identification information based on the confirmed identity information. The first control module 14 receives the identification information and outputs the first preset power corresponding to the identification information to the first connection module 11 and transmits it to the second connection module 21. The third control module 23 receives the first preset power transmitted by the second connection module 21 and outputs the second preset power to the working module 24 for the working module 24 to work.

[0104] The identity information is electronic tag information, specifically a single letter or a single number. Identity confirmation information is used to verify whether accessory 20 corresponds to the specified identity. Identity confirmed information is the information returned by accessory 20 after confirming its identity, used to reply to identification module 12 to ensure the matching degree between the first preset power output of host 10 and accessory 20. The first communication line 125 is connected between the first single-serial communication chip 124 of identification module 12, the first protection resistor 1231 of identification module 12, and the first connection module 11. The third communication line 223 is connected between the second single-serial communication chip 222 of module 22 to be identified, the second protection resistor 224 of module 22 to be identified, and the second connection module 21.

[0105] like Figure 3 As shown, the identification module 22 includes a second dual-serial communication chip 225. The second dual-serial communication chip 225 is connected to the second connection module 21 via a third communication line 223 and a fourth communication line 226. The second dual-serial communication chip 225 sends identity information to the second connection module 21 via the third communication line 223 to transmit the identity information to the host 10. The host 10 sends identity confirmation information to the second connection module 21 based on the identity information, which is then transmitted to the second dual-serial communication chip 225 via the fourth communication line 226. The second dual-serial communication chip 225 receives the identity confirmation information and sends corresponding identity-confirmed information to the second connection module 21 via the third communication line 223 to transmit the identity-confirmed information to the host 10. The host 10 outputs a first preset power to the second connection module 21. Herein, the identity confirmation information corresponds to the identity information, and the identity-confirmed information corresponds to the identity confirmation information.

[0106] Specifically, when accessory 20 is assembled onto host 10, the first control module 14 outputs identification power. This identification power flows through the first connection module 11, the second connection module 21, and the third control module 23 to reach the module to be identified 22. The second dual-serial communication chip 225 of the module to be identified receives the identification power and outputs identity information through the third communication line 223. The identity information flows through the third communication line 223 and the first communication line 125 to reach the first dual-serial communication chip 126 of the identification module 12. In other words, the identity information flows through the second connection module 21 and the first connection module 11 to reach the first communication line 125, which in turn reaches the first dual-serial communication chip 126 of the identification module 12.

[0107] It should be further explained that the first dual serial communication chip 126 of the identification module 12 outputs corresponding identity confirmation information according to the identity information. The identity confirmation information flows through the first communication line 125 and the third communication line 223 to reach the second dual serial communication chip 225 of the module to be identified 22. That is, the identity confirmation information flows through the first connection module 11 and the second connection module 21 to reach the third communication line 223, that is, to reach the second dual serial communication chip 225 of the module to be identified 22.

[0108] It should be noted that the second dual serial communication chip 225 of the identification module 22 outputs the corresponding identity confirmation information according to the identity confirmation information. The identity confirmation information flows through the second connection module 21 and the first connection module 11 to reach the first dual serial communication chip 126 of the identification module 12.

[0109] It should be further explained that the first dual serial communication chip 126 outputs corresponding identification information based on the confirmed identity information. The first control module 14 receives the identification information and outputs the first preset power corresponding to the identification information to the first connection module 11 and transmits it to the second connection module 21. The third control module 23 receives the first preset power transmitted by the second connection module 21 and outputs the second preset power to the working module 24 for the working module 24 to work.

[0110] The identity information is password information, specifically a string, which consists of one or more combinations of numbers, letters, and symbols. The identity verification information is used to confirm whether accessory 20 corresponds to the correct identity. The confirmed identity information is the information returned by accessory 20 after confirming its identity, used to reply to identification module 12 to ensure the matching degree between the first preset power output of host 10 and accessory 20. The first communication line 125 and the second communication line 127 are connected between the first single-serial communication chip 124 of identification module 12, the first protection resistor 1231 of identification module 12, and the first connection module 11. The first communication line 125 is used only for receiving information, and the second communication line 127 is used only for sending information. The third communication line 223 and the fourth communication line 226 are connected between the second single-serial communication chip 222 of the module to be identified 22, the second protection resistor 224 of the module to be identified 22, and the second connection module 21. The third communication line 223 is used only for sending information, and the fourth communication line 226 is used only for receiving information.

[0111] It should be noted that the electronic tag identification scheme uses a single serial communication chip and a single communication line. The single serial communication chip refers to the first single serial communication chip 124 and the second single serial communication chip 222, and the single communication line refers to the line connecting the first communication line 125 and the third communication line 223.

[0112] The password recognition scheme employs dual serial communication chips and two communication lines. The dual serial communication chips refer to the first dual serial communication chip 126 and the second dual serial communication chip 225. The two communication lines refer to the line connecting the first communication line 125 and the third communication line 223, and the line connecting the second communication line 127 and the fourth communication line 226. The first communication line 125 and the fourth communication line 226 are used only for receiving information, while the second communication line 127 and the third communication line 223 are used only for transmitting information, ensuring that transmitting and receiving information do not interfere with each other. Compared to the password recognition scheme, the electronic tag recognition scheme, with two communication lines compared to one, has a more complex circuit structure and higher cost. However, communication between the host 10 and the accessory 20 does not require waiting for the communication lines to be idle, the output and input communication lines do not interfere with each other, the communication speed is fast, and the communication latency is low.

[0113] Compared to electronic tag identification and chip password identification schemes, the resistor identification scheme eliminates the need for the identification module 22 to connect to a third control module 23, acquire identification power for sending identity information, or add an interface for providing identification power from the host 10 to the accessory 20. This reduces the number of interfaces and simplifies the circuit structure, thereby lowering production costs. The first control module 14 also does not need to output identification power immediately, resulting in a shorter startup waiting time and faster startup response.

[0114] like Figure 1-2 As shown, accessory 20 also includes a fourth control module 25, which is connected to the third control module 23 and is used to output a second adjustment signal. The third control module 23 adjusts the second preset power according to the second adjustment signal.

[0115] Specifically, the fourth control module 25 includes a button for the user to press to switch different usage modes of the working module 24. When the third control module 23 receives the second adjustment signal, it will call the second preset power corresponding to the second adjustment signal to supply power to the working module 24.

[0116] The working module 24 includes a motor, which has at least two operating modes, and the speed in one operating mode is greater than the speed in the other operating mode.

[0117] More specifically, the second preset power has at least two levels, for example, three levels, with the initial level being the second level.

[0118] When the user presses a button, the third control module 23 receives a second adjustment signal sent by the button. This second adjustment signal can be an upward or downward adjustment signal. The third control module 23 adjusts the second preset power upward or downward according to the upward or downward signal, switching the second preset power from the second level to the third level or the first level. When the second preset power is at the highest or lowest level, the third control module 23 receives the second adjustment signal again from the button, and then stops the output of the second preset power, or switches to the lowest or highest level, or maintains the highest or lowest level. The adjustment of the second preset power is achieved by controlling the output current or voltage.
