It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0052] See also Figure 1 The embodiment of the present application provides a smart door lock, including a driving device (not shown in the figure) and a communication device, wherein the driving device is used to drive the lock tongue to extend and retract to unlock or lock, and the communication device is electrically connected or communicatively connected to the driving device, and the communication device is used to receive a switch lock signal, and instruct the driving device to drive the lock tongue to unlock or lock according to the switch lock signal. It should be noted that the switch lock signal can be a wireless signal, an induction signal, a touch signal, or an identification signal light, and the communication device is a device that can receive wireless signals.

[0053] In the application environment of smart door locks, the communication device can be installed outside the door panel as an outdoor unit, and can be used to receive password unlocking signals triggered by buttons, fingerprint unlocking signals from fingerprint recognition modules, wireless signals from smart devices such as mobile phones or tablets, etc. The drive device can be installed on the inside of the door panel as an indoor unit, and is connected to the lock cylinder in the door panel, and can drive the lock tongue to extend and retract through the lock cylinder. After receiving the lock opening and closing signal, the communication device instructs the drive device to unlock or close the lock according to the signal, so as to realize the automatic lock opening and closing function of the smart door lock.

[0054] It can be understood that the communication device of the present application can be applied not only to smart door locks, but also to other devices with buttons and communication functions.

[0055] See again Figure 1 The communication device includes a housing component 1 and an antenna 2. The housing component 1 includes a shell 11, and the shell 11 is provided with a key area 18. The antenna 2 is arranged around at least a portion of the key area 18. The antenna 2 can be arranged around the entire key area 18, or can be inserted in the key area 18 and arranged around a portion of the key area.

[0056] In one embodiment, the smart door lock usually has a password unlocking function, so the communication device is provided with a key area 18, and the key area 18 is used for the user to input a digital password to realize the unlocking function; the key area 18 usually occupies a large area, and the present application arranges the antenna 2 around at least part of the key area 18, which can effectively increase the design area of ​​the antenna 2. Compared with the prior art, the present application reasonably arranges the installation position of the antenna 2 without increasing the original volume of the device, arranges the antenna 2 around the key area 18, increases the coverage range of the antenna 2, and improves the distance of wireless transmission. The smart door lock using this communication device can realize the function of long-distance wireless unlocking or locking, and there is no need to increase the original design volume of the smart door lock, saving production costs.

[0057] See also Figure 2 The communication device also includes a circuit component 3, the housing 11 is provided with a housing cavity 19, and the circuit component 3 is arranged in the housing cavity 19; the antenna 2 is arranged on the outer side of the housing 11 away from the housing cavity 19, and at least part of the antenna 2 extends into the housing cavity 19 and is electrically connected to the circuit component 3.

[0058] In one embodiment, a accommodating cavity 19 is opened inside the shell 11, and the circuit component 3 is installed in the accommodating cavity 19. The accommodating cavity 19 protects the circuit component 3 and prevents the external environment from polluting the circuit component 3; the antenna 2 is arranged on the outer side of the shell 11 away from the accommodating cavity 19, and the antenna 2 is only partially electrically connected to the circuit component 3. The antenna 2 is used to receive the wireless signal transmitted by the user and transmit the wireless signal to the circuit component 3. For example, the antenna 2 can be an NFC antenna, which can be used to sense the wireless signal emitted by the user's NFC key, and the circuit component 3 outputs an unlocking or locking instruction according to the wireless signal; compared with the prior art in which the antenna 2 is set on the circuit component 3, the present application sets the antenna 2 on the shell 11. When the design area of ​​the antenna 2 is expanded, the design area of ​​the circuit component 3 does not need to be expanded accordingly. This arrangement saves the production cost of the circuit design and improves the economic efficiency.

[0059] See also Figure 3 The shell assembly 1 also includes a panel 12. A first mounting groove 111 is formed on the outer side of the shell 11 facing away from the accommodating cavity 19. The first mounting groove 111 is arranged around at least a portion of the button area 18. The antenna 2 is arranged in the first mounting groove 111. The panel 12 is connected to the shell 11 and covered in the first mounting groove 111.

[0060] In actual use, smart door locks are usually located outdoors and are easily affected by rain, moisture and other impurities. Therefore, the shell assembly 1 is also provided with a panel 12, and the panel 12 covers the first mounting groove 111. The panel 12 can protect the antenna 2 and prevent external impurities from entering the first mounting groove 111, causing damage to the antenna 2, thereby affecting the antenna 2's ability to receive signals. At the same time, the panel 12 can also fix the antenna 2 in the first mounting groove 111 through a fixed connection with the shell 11, effectively preventing the antenna 2 from detaching from the shell 11.

[0061] See again Figure 3 In one embodiment, a second mounting groove 113 is further formed on the outer side of the shell 11 facing away from the accommodating cavity 19 , and the bottom of the second mounting groove 113 is at least partially recessed inward to form the first mounting groove 111 , and the panel 12 is connected to the second mounting groove 113 and covers the first mounting groove 111 .

[0062] The outer shell 11 is provided with a second mounting groove 113, and the panel 12 is arranged and embedded in the second mounting groove 113. With this arrangement, the outer surface of the panel 12 and the outer shell 11 can be flush, and the panel 12 does not protrude from the outer shell 11, which is more beautiful in appearance, and can prevent water vapor from penetrating into the first mounting groove 111 through the gap between the panel 12 and the outer shell 11, thereby playing a waterproof and dustproof role.

[0063] In one embodiment, the housing assembly 1 further includes a first waterproof layer (not shown in the figure), which is located between the panel 12 and the housing 11 and is used to connect the panel 12 and the housing 11 .

[0064] In order to further prevent external water vapor from contaminating the antenna 2, a first waterproof layer is provided between the panel 12 and the housing 11. The first waterproof layer can be made of waterproof glue, which can not only fix the panel 12 and the housing 11 together, but also play a waterproof role to prevent the antenna 2 from getting wet. Exemplarily, the first waterproof layer can be provided around the outer edge of the entire panel 12 to prevent external water vapor from entering between the panel 12 and the housing 11.

[0065] See again Figure 3 The housing 11 further defines a first through hole 112 , which connects the first mounting groove 111 with the accommodating cavity 19 . At least a portion of the antenna 2 extends from the first through hole 112 into the housing 11 and is electrically connected to the circuit component 3 .

[0066] In one embodiment, the housing 11 is provided with a first through hole 112 connecting the first mounting groove 111 and the accommodating cavity 19. The antenna 2 is partially installed in the first mounting groove 111 and partially extends from the first through hole 112 into the accommodating cavity 19 to be electrically connected to the circuit assembly 3. This arrangement makes the connection between the antenna 2 and the circuit assembly 3 easier and the structural layout more compact. Optionally, the opening position of the first through hole 112 is also located in the key area 18.

[0067] See again Figure 3 The antenna 2 includes a ring portion 21 and a straight portion 22 . The ring portion 21 is disposed in the first mounting groove 111 . One end of the straight portion 22 is connected to the ring portion 21 , and the other end extends into the accommodating cavity 19 to be electrically connected to the circuit component 3 .

[0068] In one embodiment, the antenna 2 includes an annular portion 21 and a straight portion 22. The annular portion 21 can be arranged around at least a portion of the key area 18 to expand the coverage area of ​​the antenna 2; and the straight portion 22 is mainly used to connect the circuit component 3. Specifically, one end of the straight portion 22 is connected to the annular portion 21, and the other end extends from the first through hole 112 into the accommodating cavity 19 to connect with the circuit component 3, thereby realizing the electrical connection between the antenna 2 and the circuit component 3.

[0069] See also Figure 4 One end of the antenna 2 extending into the accommodating cavity 19 is bent toward the inner side surface of the shell 11, and the circuit component 3 includes a power connection portion 32 extending toward the inner side surface of the shell 11, and the power connection portion 32 contacts the antenna 2 extending into the accommodating cavity 19 to achieve electrical connection.

[0070] In one embodiment, the straight portion 22 of the antenna 2 extends into the accommodating cavity 19 and is bent toward the inner side surface of the outer shell 11 to form a bent portion 23, and the bent portion 23 can be parallel to the inner side surface of the outer shell 11; the circuit assembly 3 includes a circuit board 31 and a power connection portion 32, the circuit board 31 is installed in the accommodating cavity 19, the power connection portion 32 is connected to the side of the circuit board 31 facing the antenna 2, and the power connection portion 32 extends toward the antenna 2 until the power connection portion 32 is electrically contacted with the bent portion 23, thereby realizing the electrical connection between the antenna 2 and the circuit assembly 3; the bent portion 23 can abut against the inner side surface of the outer shell 11 to play a fixing role, preventing the bent portion 23 from detaching from the accommodating cavity 19, and also facilitating the stable contact between the power connection portion 32 and the bent portion 23, thereby ensuring the connection stability between the antenna 2 and the circuit assembly 3.

[0071] In one embodiment, the power connection portion 32 may be a contact spring pin welded on the circuit board 31 , and a power connection area is provided on the bending portion 23 , and the contact probe and the power connection area are electrically connected.

[0072] See also Figure 5 and Figure 6 A positioning column 13 is provided on the inner side of the housing 11 , and a positioning hole 24 is opened at one end of the antenna 2 extending into the accommodating cavity 19 , and the positioning column 13 cooperates with the positioning hole 24 .

[0073] In one embodiment, a positioning column 13 is provided on the side of the outer shell 11 facing the circuit component 3, and a positioning hole 24 is provided at one end of the antenna 2 extending into the accommodating cavity 19. Specifically, a positioning hole 24 is provided on the bending portion 23 of the antenna 2. When the bending portion 23 abuts against the inner side surface of the outer shell 11, the positioning hole 24 is plugged into and cooperates with the positioning column 13, thereby further preventing the bending portion 23 from detaching from the accommodating cavity 19, thereby enhancing the connection stability between the antenna 2 and the circuit component 3.

[0074] See also Figure 7 The communication device also includes a key assembly 4 located in the accommodating cavity 19 , a key area 18 is provided with a key hole 17 , a part of the key assembly 4 extends out of the key hole 17 , and another part of the key assembly 4 is used to press the trigger circuit assembly 3 .

[0075] In one embodiment, in order to facilitate the input of passwords in the smart door lock, the present application sets a physical key assembly 4, which is arranged between the circuit assembly 3 and the housing 11, and a part of the key assembly 4 extends out of the key hole 17 for the convenience of the user to press, and the user can input the unlocking password by pressing the key assembly 4. When the user presses the key assembly 4, the key assembly 4 moves in the direction close to the circuit assembly 3 to touch the circuit assembly 3, and the circuit assembly 3 outputs an unlocking instruction according to the digital password input by the user to realize the password unlocking function.

[0076] See also Figure 8The button assembly 4 includes a flexible pad 41, which is located between the circuit assembly 3 and the housing 11 and covers the button area 18. A sealing ridge 411 is provided on the outer periphery of the flexible pad 41. A fixing groove 115 is provided on the inner side of the housing 11. The sealing ridge 411 is embedded in the fixing groove 115. The circuit assembly 3 is fixedly connected to the housing 11 and presses the flexible pad 41 against the housing 11.

[0077] It can be understood that the flexible pad 41 refers to a pad made of a flexible material, such as soft glue or silicone material, which has a certain deformation ability.

[0078] In one embodiment, the sealing ridge 411 is circumferentially arranged on the outer periphery of the flexible pad 41, and the sealing ridge 411 extends toward the direction close to the housing 11. The fixing groove 115 can be arranged around the key area 18, and the sealing ridge 411 is inserted into the fixing groove 115. At the same time, the circuit component 3 is fixedly connected to the housing 11, and the circuit component 3 presses the flexible pad 41, and the flexible pad 41 is pressed tightly against the housing 11 to fix the flexible pad 41.

[0079] Since the button area 18 is provided with a button hole 17, external water vapor can easily enter into the accommodating cavity 19 inside the shell 11 through the button hole 17. The above-mentioned arrangement is used to press the flexible pad 41 between the circuit component 3 and the shell 11. The flexible pad 41 can protect the internal circuit component 3 and prevent water vapor from damaging the circuit component 3; and the sealing ridge 411 arranged on the outer periphery of the flexible pad 41 can further enhance the waterproof function. Even if a small amount of water vapor passes through the button hole 17, the water vapor is sealed between the flexible pad 41 and the shell 11 under the sealed connection between the sealing ridge 411 and the fixing groove 115, and cannot enter the circuit component 3, thereby further protecting the circuit component 3.

[0080] See again Figure 5 In one embodiment, the flexible pad 41 is further provided with a fixing column 416, which extends in a direction close to the outer shell 11. The inner side of the outer shell 11 is further provided with a positioning groove 117, and the fixing column 416 is plugged into the positioning groove 117. When assembling the flexible pad 41, the positioning function of the fixing column 416 and the positioning groove 117 can realize the rapid positioning of the flexible pad 41, thereby simplifying the assembly steps.

[0081] See again Figure 7The above-mentioned button assembly 4 also includes a keycap 42, and the flexible pad 41 also includes a pad portion 413 and a button portion 414. The pad portion 413 covers the button area 18, and the button portion 414 is connected to the pad portion 413. One end of the button portion 414 extends into the button hole 17, and the other end extends toward the direction close to the circuit assembly 3. The circuit assembly 3 is provided with a touch switch corresponding to the button portion 414; the keycap 42 is arranged in the button hole 17 and covers the button portion 414, and the button portion 414 is used to press and trigger the touch switch.

[0082] In one embodiment, the pad portion 413 is located between the housing 11 and the circuit assembly 3, and the button portion 414 is connected to the pad portion 413, with one end extending out of the button hole 17 and the other end extending in the direction close to the circuit assembly 3; the circuit assembly 3 also includes a trigger switch 34, which is connected to the side of the circuit board 31 facing the button assembly 4. When the user presses the button portion 414 through the key cap 42, the button portion 414 squeezes the trigger switch 34, and the trigger switch 34 is in electrical contact with the circuit board 31, satisfying the user interaction function. The button assembly 4 also includes a key cap 42, which is covered on the top of the button portion 414, providing the user with a more comfortable pressing feel, and facilitating the user to press the button portion 414; it can also protect the button portion 414 and prevent the button portion 414 from being damaged.

[0083] The trigger switch 34 may be a pot piece. The number of the button portion 414 may be multiple to correspond to different numbers and function keys.
