[0021] Please refer to Figure 1 , the intelligent door lock 100 includes a power module 2, a Type-C interface module 1, a door lock assembly 4, a switch assembly 3 and a control module 5, the Type-C interface module 1 is connected with the power module 2, the power module 2 charges through the Type-C interface module 1, the power module 2, the Type-C interface module 1, the door lock assembly 4, the switch assembly 3 are connected with the control module 5, the control module 5 carries out signal interaction with external equipment through the Type-C interface module 1, the switch assembly 3 is used to send control signal to the control module 5, and the control module 5 controls the opening and closing of the door lock assembly 4 according to the control signal.

[0022] For the above Type-C interface module 1, please refer to Figure 2 , the Type-C interface module 1 includes a Type-C interface 11, a level conversion circuit 12 and a protection circuit 13, the level conversion circuit 12 and the protection circuit 13 are connected with the Type-C interface 11, the power module 2 and the control module 5 respectively, and the protection circuit 13 is grounded. The Type-C interface 11 includes a power pin 112, a ground pin 111 and a signal pin 113, the power pin 112 is connected with the power module 2, the ground pin 111 is used for grounding, and the signal pin 113 is used for connecting with the signal end of the control module 5.

[0023] In some embodiments, the signal pin 113 includes a CC1 pin and a CC2 pin, the signal end of the control module 5 includes a signal input end MCU_RX and a signal output end MCU_TX, the CC1 pin is connected with the signal input end MCU_RX of the control module 5, and the CC2 pin is connected with the signal output end MCU_TX of the control module 5.

[0024] In some embodiments, the ground pin 111 includes two GND pins, both of which are used for grounding, effectively dispersing the ground current, reducing the ground impedance and improving the durability and safety of the Type-C interface 11.

[0025] In some embodiments, the power pin 112 includes two VBUS pins, which are connected and connected with the power module 2.

[0026] It can be understood that the number of pins of the Type-C interface 11 is determined according to actual application requirements. In some embodiments, the Type-C interface 11 further includes an audio pin for connecting external audio equipment such as earphones or loudspeakers to realize audio output or input function. Preferably, the Type-C interface 11 includes six pins, which are GND pin, VBUS pin, CC1 pin, CC2 pin, VBUS pin and GND pin arranged in sequence.

[0027] In some embodiments, please refer to Figure 2 The Type-C interface module 1 further comprises a first diode D1, the two VBUS pins are connected to the input end of the first diode D1, and the output end of the first diode D1 is connected to the input end SYS_5V of the power module 2. The first diode D1 is connected between the power pin 112 and the power module 2, and the first diode D1 has a forward conduction characteristic, which is used to prevent the reverse connection of the power supply and only allows the current to flow from the external power supply to the power module 2, thereby improving the power supply safety of the intelligent door lock 100.

[0028] For the above-mentioned level conversion circuit 12, the level conversion circuit 12 comprises a second diode D2, a third diode D3 and a first resistor R1, the first end of the first resistor R1 is connected to the output end SYS_3V3 of the power module 2, the second end of the first resistor R1 is connected to the input end of the second diode D2, the input end of the second diode D2 is connected to the signal input end MCU_RX of the control module 5, the output end of the second diode D2 is connected to the CC1 pin, the input end of the third diode D3 is connected to the signal output end MCU_TX of the control module 5, and the output end of the third diode D3 is connected to the CC2 pin.

[0029] It should be noted that, due to the forward conduction characteristic of the second diode D2, when the input end of the CC1 pin inputs a high level, the second diode D2 is cut off, and the signal input end MCU_RX of the control module 5 is kept at a high level through the first resistor R1. When the input end of the CC1 pin inputs a low level, the second diode D2 is turned on, and the signal input end MCU_RX of the control module 5 is pulled low to a low level through the second diode D2. The second diode D2 and the first resistor R1 ensure that the signal can be accurately and losslessly transmitted between the CC1 pin and the signal input end MCU_RX of the control module 5, regardless of whether the external device sends a high level signal or a low level signal, the control module 5 can correctly identify and make corresponding processing.

[0030] For the third diode D3, when the control module 5 needs to send a signal to the external device, the signal output end MCU_TX generates a high level or low level signal, which is then transmitted to the CC2 pin by the third diode D3. Due to the unidirectional conduction characteristic of the third diode D3, the signal is not easy to distort or attenuate during transmission, thereby ensuring the reliability and stability of signal transmission.

[0031] For the above-mentioned protection circuit 13, please continue to refer to Figure 2The protection circuit 13 includes a fourth diode D4, a fifth diode D5, and a sixth diode D6. The first end of the fourth diode D4 is connected to the input end of the power module 2 and the power pin 112. The first end of the fifth diode D5 is connected to the output end of the second diode D2 and the CC1 pin. One end of the sixth diode D6 is connected to the output end of the third diode D3 and the CC2 pin. The second end of the fourth diode D4, the second end of the fifth diode D5, and the second end of the sixth diode D6 are connected and grounded. The protection circuit 13 is used to prevent overvoltage, overcurrent, or reverse voltage from damaging the Type-C interface module 1 and the internal circuit of the smart door lock 100. When overvoltage occurs at the input end of the power module 2 or the power pin 112, the fourth diode D4 will quickly conduct and lead the excess voltage to the ground, thereby protecting the power module 2 from damage. Similarly, when the CC1 pin or the CC2 pin receives an excessively high signal voltage or a reverse voltage, the fifth diode D5 and the sixth diode D6 will conduct, respectively, to lead the abnormal voltage to the ground, ensuring the safety and stability of signal transmission.

[0032] In addition, the protection circuit 13 also has electrostatic discharge (ESD) protection function. In a dry environment, static electricity may be generated when a human body or other objects come into contact with the Type-C interface 11. This instantaneous voltage impact may cause damage to the circuit. However, due to the presence of the fourth, fifth, and sixth diodes D6, they can quickly absorb and disperse this static discharge energy, effectively preventing static electricity from damaging the internal circuit of the smart door lock 100.

[0033] In some embodiments, at least one of the fourth diode D4, the fifth diode D5, and the sixth diode D6 is a bidirectional diode. Preferably, the fourth diode D4, the fifth diode D5, and the sixth diode D6 are all bidirectional diodes, so that the protection circuit 13 can not only cope with forward and reverse overvoltage situations, but also provide effective protection under bidirectional voltage impact.

[0034] For the above-mentioned switch assembly 3, the switch assembly 3 includes at least one of a password key, a fingerprint identifier, and a face recognizer, for sending a control signal to the control module 5. When a user verifies his identity through the switch assembly 3, for example, by entering a password, scanning a fingerprint, or performing face recognition, the switch assembly 3 will generate a corresponding control signal and send it to the control module 5. After receiving the signal, the control module 5 will perform identity verification processing by comparing the preset verification information (such as stored password, fingerprint feature, or face image) with the verification information provided by the user to determine whether the user has the right to open the door lock.

[0035] If the verification is passed, the control module 5 sends an opening instruction to the door lock assembly 4, and the door lock assembly 4 performs the opening operation according to the instruction to allow the user to enter. This process is usually very fast to ensure that the user can use the smart door lock 100 smoothly. If the verification fails, the control module 5 does not send the opening instruction, and the door lock assembly 4 remains in the locked state, and in some embodiments, the control module 5 sends information about the failed verification to the user through the Type-C interface module 1 or other prompt devices (such as LED indicators, sound prompts, etc.) on the smart door lock 100, prompting the user to re-verify or check the correctness of the input information.

[0036] For the above-mentioned door lock assembly 4, the door lock assembly 4 includes a lock tongue, a lock body, and a driving mechanism, the lock tongue and the driving mechanism are installed in the lock body, the lock body is used to be connected with the door, and the lock body is connected with the control module 5 to receive the opening or closing instruction sent by the control module 5 and drive the lock tongue to perform corresponding actions. The driving mechanism is used to convert the electrical signal sent by the control module 5 into mechanical energy to control the extension and retraction of the lock tongue. In some embodiments, the driving mechanism includes a motor or an electromagnetic valve and the like.

[0037] For the above-mentioned control module 5, the control module 5 is used to receive, process and send various signals to realize the intelligent control of the door lock. The control module 5 includes a processor, a memory and a communication interface and the like, the processor core is responsible for executing various instructions, the memory is used to store temporary data and program codes, and the communication interface is used to communicate with the Type-C interface module 1, the door lock assembly 4, the switch assembly 3 and other external devices. In some embodiments, the control module 5 can be a microcontroller MCU.

[0039] In the production detection stage, the control module 5 receives the detection signal from the production detection device through the Type-C interface module 1, and the signal contains a series of test instructions for various functions of the smart door lock 100. The control module 5 drives the door lock assembly 4, the switch assembly 3 and the like to perform corresponding actions according to these instructions, and feeds back the detection results to the production equipment through the Type-C interface module 1, so that the production personnel can quickly understand the various performance indicators of the smart door lock 100 to ensure the quality of the product out of the factory.
