[0032] See also Figures 1 to 3 The present embodiment provides a smart doorbell device, including a doorbell body 1 and a wall plate 2. The upper and lower ends of the back side of the housing 101 of the doorbell body 1 are respectively provided with a first hanging hole 10121 and a second hanging hole 10122, and the upper and lower ends of the front side of the wall plate 2 are respectively provided with a first hook 201 matched with the first hanging hole 10121 and a second hook 202 matched with the second hanging hole 10122, and a locking mechanism 102 is provided in the first hanging hole 10121. When the first hook 201 and the second hook 202 are respectively inserted into the first hanging hole 10121 and the second hanging hole 10122, the locking mechanism 102 locks the first hook 201 in the first hanging hole 10121, thereby realizing rapid assembly of the doorbell body 1 and the wall plate 2. In addition, a plurality of mounting holes 203 are respectively provided at the upper and lower ends of the front side of the wall plate 2. By using with screws, the mounting holes 203 can ensure that the wall plate 2 is firmly installed in the desired position, thereby ensuring the stability and reliability of the doorbell device.

[0033] By optimizing the structural design, the smart doorbell device of this embodiment realizes the rapid assembly of the doorbell body 1 and the wall plate 2. The first hanging hole 10121 and the second hanging hole 10122 on the doorbell body 1 cooperate with the first hook 201 and the second hook 202 on the wall plate 2, making the installation process simple and quick, reducing the difficulty and cost of installation. The design of the locking mechanism 102 enhances the stability and safety of the doorbell device. Once the first hook 201 and the second hook 202 are respectively inserted into the first hanging hole 10121 and the second hanging hole 10122, the locking mechanism 102 will immediately lock the first hook 201 in the first hanging hole 10121, effectively preventing the doorbell body 1 from being easily disassembled. This anti-disassembly function can greatly reduce the possibility of criminals dismantling the doorbell in order to evade monitoring, and improve the anti-theft performance of the doorbell.

[0034] See also Figure 1 , Figure 3 In one embodiment, the shell 101 of the doorbell body 1 includes a front shell 1011 and a rear shell 1012, a first hanging hole 10121 and a second hanging hole 10122 are opened at the upper end and the lower end of the back side of the rear shell 1012, and a receiving groove 10123 for receiving the locking mechanism 102 is arranged at the top of the front side of the rear shell 1012, and the receiving groove 10123 is connected with the first hanging hole 10121, and the top plate of the front shell 1011 covers the upper opening of the receiving groove 10123 to hide the locking mechanism 102 and prevent criminals from easily disassembling the doorbell body 1. The locking mechanism 102 includes a locking tongue 1021 and a spring 1022. The locking tongue 1021 is arranged in the receiving groove 10123 and can slide up and down along the receiving groove 10123. The spring 1022 is arranged between the locking tongue 1021 and the bottom wall of the receiving groove 10123. When the first hook 201 and the second hook 202 are respectively inserted into the first hanging hole 10121 and the second hanging hole 10122, the locking tongue 1021 clamps the first hook 201 upward under the elastic force of the spring 1022. By arranging the receiving groove 10123 for accommodating the locking mechanism 102 at the top of the front of the rear shell 1012, the space is effectively utilized, and the locking mechanism 102 can be ensured to work smoothly. The communication between the receiving groove 10123 and the first hanging hole 10121 enables the locking tongue 1021 to slide freely and clamp the first hook 201. The locking mechanism 102 adopts a mechanical locking method of a lock tongue 1021 and a spring 1022, which is simple and effective. Because the lock tongue 1021 clamps the first hook 201 upward under the elastic force of the spring 1022, when the hook is inserted into the hanging hole, the lock tongue 1021 will automatically lock the hook to prevent it from falling off. This design not only enhances the anti-disassembly performance of the doorbell device, but also ensures the stability of the installation.

[0035] See also Figure 1 , Figure 3In one embodiment, a disassembly slot 10211 is provided on the top of the lock tongue 1021, and a disassembly opening 10111 is provided on the top plate of the front shell 1011 at a position corresponding to the disassembly slot 10211. When the doorbell body 1 needs to be disassembled, it is only necessary to use a tool that can be inserted into the disassembly opening 10111 and the disassembly slot 10211 to press down the top of the lock tongue 1021, so that the lock tongue 1021 slides downward, and the lock on the first hook 201 is released, and the doorbell body 1 can be easily detached from the wall hanging plate 2. This design makes the disassembly process of the doorbell body 1 simple and fast, and improves the user experience. In addition, the apertures of the disassembly slot 10211 and the disassembly opening 10111 are designed to be very small and not easy to be found, which increases the safety of the device. For criminals who do not understand the structure of the device, it is difficult for them to realize the existence of these small holes, and it is even more impossible to think of disassembling the doorbell body 1 in this way. Therefore, this design effectively prevents criminals from easily disassembling the doorbell body 1 and enhances the anti-disassembly performance of the doorbell device.

[0036] See also Figure 1 , Figure 2 , Figure 4In one embodiment, a main camera 103 and a ring button 104 are arranged on the front of the housing 101, and a speaker 105, a detachment sensor 106, a first wireless communication module 107, a battery 108 and a first control mainboard 109 are arranged inside the housing 101. The first control mainboard 109 is electrically connected to the main camera 103, the ring button 104, the speaker 105, the detachment sensor 106, the first wireless communication module 107 and the battery 108 respectively. The main camera 103 is used to capture the image of the visitor and provide the user with more intuitive information. After the ring button 104 is pressed, the first control mainboard 109 controls the speaker 105 to sound a ring to remind the user that a visitor is visiting. The battery 108 is used to power the doorbell body 1, so that the doorbell body 1 is free from the constraints of wires. The battery 108 is preferably a large-capacity battery, so that the doorbell body 1 has a strong endurance and does not need to be frequently charged or replaced. The doorbell body 1 can be connected to the WiFi network through the first wireless communication module 107, and then connected to the cloud server for data exchange, thus realizing remote monitoring and management. The user can check the status of the doorbell, receive alarm information, and view the captured video at any time through a mobile phone or other terminal device, so as to quickly and easily grasp the safety status of the home. Regardless of whether the criminals disassemble the doorbell body 1 in a normal way or in a violent way, when the detachment sensor 106 detects that the doorbell body 1 is separated from the wall plate 2, the first control mainboard 109 will control the speaker 105 to sound an alarm, effectively attracting the attention of the surrounding people and deterring the criminals, and the first control mainboard 109 will send an alarm notification to the user's mobile phone, and the main camera 103 will upload the captured video to the cloud server. In this way, even if the user is not at the scene, he can view the captured video through the cloud server to understand the situation at the scene, further enhancing the security monitoring function of the doorbell.

[0037] In some specific embodiments, the detachment sensor 106 is a vibration sensor. When the criminals disassemble the doorbell body 1 , the vibration sensor will detect the vibration of the doorbell body 1 , thereby sending an alarm signal to the first control mainboard 109 .

[0038] In some specific embodiments, the detachment sensor 106 is a touch switch. After the doorbell body 1 is installed on the wall plate 2, the touch switch is in a pressed state. When criminals dismantle the doorbell body 1, the wall plate 2 will contact the pressing of the touch switch, thereby sending an alarm signal to the first control main board 109.

[0039] In some specific embodiments, the disassembly sensor 106 is a photosensitive element. When a criminal disassembles the doorbell body 1 , the photosensitive element detects a change in brightness, thereby sending an alarm signal to the first control mainboard 109 .

[0040] See also Figure 1 , Figure 2In one embodiment, a sealing silicone ring 110 is provided at the connection between the front shell 1011 and the rear shell 1012, a main lens sealing silicone 111 is provided between the main camera 103 and the housing 101, and a button sealing silicone 112 is provided between the ring button 104 and the housing 101. Since the doorbell body 1 is usually installed outdoors, it faces various complex natural environments, such as rain, dust, etc. The sealing silicone ring 110 is provided at the connection between the front shell 1011 and the rear shell 1012, which can effectively prevent moisture and dust from penetrating from the gap of the housing 101, and ensure the dryness and cleanliness of the electronic components inside the doorbell. The main camera 103 is one of the core components of the doorbell. If it is corroded by water or dust, it may cause image quality degradation or functional failure. By using the main lens sealing silicone 111, it can be ensured that the main camera 103 always remains clear and stable when working. At the same time, the ring button 104 is the main way for users to interact with the doorbell, and its sealing is also very important. The use of key sealing silicone 112 ensures the sensitivity and reliability of the keys and prevents key failure due to water or dust.

[0041] See also Figure 1 , Figure 4 In one embodiment, a charging interface 113, a power button 114, a reset button 115 and a storage card slot 116 are provided on the back of the housing 101, and the first control mainboard 109 is electrically connected to the charging interface 113, the power button 114, the reset button 115 and the storage card slot 116 respectively. The setting of the charging interface 113 enables the doorbell body 1 to be easily charged, ensuring the continuous and stable operation of the doorbell. The setting of the power button 114 provides the convenience of the user to manually turn on and off the doorbell, so that the user can control the working state of the doorbell as needed. The presence of the reset button 115 provides a way to solve equipment failures or abnormalities. The user can restart the doorbell by pressing the reset button 115 to restore normal working state. The setting of the storage card slot 116 further expands the function of the doorbell body 1. By inserting a storage card, the doorbell can record and save more video data, providing users with a larger storage space. This is very useful for users who need to monitor or record for a long time.

[0042] See also Figure 1In one embodiment, a first sealing silicone plug 117 for sealing the charging interface 113, the power button 114, and the reset button 115 and a second sealing silicone plug 118 for sealing the storage card slot 116 are provided on the back of the housing 101. The provision of the first sealing silicone plug 117 and the second sealing silicone plug 118 ensures the sealing of the charging interface 113, the power button 114, the reset button 115, and the storage card slot 116. This can effectively prevent foreign substances such as moisture and dust from penetrating into the doorbell through these interfaces and buttons, protecting the electronic components inside the doorbell from damage. This sealing design not only improves the waterproof and dustproof performance of the doorbell, but also extends the service life of the doorbell.

[0043] See also Figure 2 , Figure 4 In one embodiment, a human body sensor 119 is also provided on the front of the housing 101, and the human body sensor 119 is electrically connected to the first control main board 109. The human body sensor 119 is used to monitor the surrounding environment in real time. When a person is detected approaching, the main camera 103 is automatically triggered to start, so that the doorbell can capture the image of the visitor more accurately, thereby improving the monitoring effect. The setting of the human body sensor 119 helps to save energy and reduce consumption. When no one is approaching, the main camera 103 is in a dormant state, thereby avoiding unnecessary power consumption. When the human body sensor 119 detects a person, the main camera 103 is awakened to work. This on-demand start-up method effectively reduces the energy consumption of the doorbell and prolongs its service life. Traditional doorbells often require users to actively press a button to trigger a response, while the human body sensor 119 can automatically detect the arrival of a person and quickly start the main camera 103 to record. This instant response design enables the doorbell to better meet the actual needs of users, improve the user experience, and can also record the theft process of unauthorized elements in a timely manner.

[0044] See also Figure 2 , Figure 4 In one embodiment, the bottom of the housing 101 is tilted upward and is provided with a secondary camera 120, which is electrically connected to the first control main board 109. The addition of the secondary camera 120 effectively expands the monitoring range of the doorbell. Although the main camera 103 can capture the field of view directly in front, there is a blind spot for the field of view at the bottom or other sides of the doorbell body 1. By setting the secondary camera 120 and tilting it upward to shoot, the image of the bottom of the doorbell and the surrounding environment can be captured, thereby filling the monitoring blind spot of the main camera 103. This multi-angle monitoring design enables the doorbell to monitor the surrounding environment more comprehensively, improving the integrity and accuracy of the monitoring.

[0045] See also Figure 2In one embodiment, a secondary lens sealing silicone 121 is provided between the secondary camera 120 and the housing 101. Since the doorbell body 1 is usually installed outdoors, it faces various complex natural environments, such as rain, dust, etc. The secondary camera 120 is one of the core components of the doorbell. If it is corroded by water or dust, it may cause image quality degradation or functional failure. By using the secondary lens sealing silicone 121, it can ensure that the secondary camera 120 always remains clear and stable when working.

[0046] See also Figure 5 In one embodiment, the smart doorbell device further includes a ringing receiver 3, the ringing receiver 3 includes a buzzer 301, a second wireless communication module 302 and a second control mainboard 303, the second control mainboard 303 is electrically connected to the buzzer 301 and the second wireless communication module 302 respectively; a third wireless communication module 122 is arranged inside the housing 101, the first control mainboard 109 is electrically connected to the third wireless communication module 122, and the third wireless communication module 122 is also wirelessly connected to the second wireless communication module 302. The ringing receiver 3 makes a sound through the buzzer 301, and can remind the user in time that someone is visiting when the visitor presses the ringing button 104 of the doorbell body 1. This reminder method is intuitive and effective, avoiding the situation where the user misses the visitor because he does not notice the doorbell sound at the door. The ringing receiver 3 uses the second wireless communication module 302 to wirelessly connect with the third wireless communication module 122 of the doorbell body 1, realizing stable signal transmission. This wireless connection method not only makes the installation position of the ringing receiver 3 more flexible, and can be placed at any position indoors according to the needs of the user, but also avoids the wiring troubles and damage risks that may be caused by wired connection.
