Technical Field

[0001] This application relates to the field of smart doorbells, and more specifically, to an indoor doorbell module for use in smart doorbells and a smart doorbell. Background Technology

[0002] In related technologies, smart doorbells are widely used in smart homes. A typical smart doorbell consists of two parts: an indoor doorbell module and an outdoor control module. The outdoor control module is the main body of the smart doorbell; in addition to basic doorbell functions, it can also integrate a camera for video monitoring. The indoor doorbell module, designed to ensure that people inside hear the alert audio while minimizing disturbance to public areas outside, is installed indoors and communicates with the outdoor control module via wireless communication technology. When the outdoor control module is activated, the indoor doorbell module receives the trigger signal and emits an alert audio.

[0003] In the process of implementing this disclosure, at least the following technical problems were found in the related technology:

[0004] In related technologies, the indoor operating module can be directly powered by an indoor socket, while the outdoor operating module lacks a socket for power supply. Therefore, the outdoor operating module is powered by its internal battery. Charging the outdoor operating module requires searching for a charging adapter or charger, which is extremely inconvenient. Furthermore, if the charging adapter or charger is incompatible with the charging power of the outdoor operating module, it can easily shorten the battery life of the outdoor operating module. Therefore, improving the charging convenience of the outdoor operating module and reducing the risk of shortened battery life due to charging has become an urgent technical problem to be solved.

[0046] Combination Figure 1 and Figure 2 As shown in the figure, the indoor doorbell module 100 for a smart doorbell provided in this embodiment includes: a housing 110, a power input unit 120, a sound output unit 130, and a charging unit 140. The power input unit 120 is embedded in the front panel of the housing 110 and is used to form a pluggable electrical connection with an external power source. The sound output unit 130 is disposed within the housing 110, electrically connected to the output terminal of the power input unit 120, and communicatively connected to the outdoor operation module of the smart doorbell, used to emit a prompt audio in response to the trigger signal of the outdoor operation module. The charging unit 140 is disposed in the housing 110 and electrically connected to the output terminal of the power input unit 120. When the outdoor operation module is connected to the charging unit 140, the charging unit 140 provides charging power to the outdoor operation module.

[0047] Specifically, the housing 110 is the main structure of the indoor Dingdong module 100, which provides space for the installation and protection of other units, so that the entire indoor Dingdong module 100 can form a whole and work stably.

[0048] Optionally, the housing 110 is made of flame-retardant material (e.g., ABS engineering plastic) to isolate the internal circuitry of the housing 110 from the external environment, thereby providing electrical protection for the various units inside the housing 110.

[0049] Optionally, heat dissipation holes are provided on the side wall of the housing 110 to accelerate the heat dissipation rate of the power input unit 120 and the charging unit 140 during operation.

[0050] Specifically, by embedding the power input unit 120 in the front panel of the housing 110, it is convenient for users to plug and unplug, facilitating the connection and disconnection of the indoor Dingdong module 100 with an external power source. By electrically connecting the power input unit 120 to an external power source, electrical energy can be obtained from the external power source to provide power support for other units.

[0051] Specifically, by housing the sound output unit 130 within the housing 110, interference and damage from the external environment can be prevented. Electrically connecting the sound output unit 130 to the output of the power input unit 120 allows it to receive power from the power input unit 120. Communicationally connecting the sound output unit 130 to the outdoor operation module of the smart doorbell allows it to receive trigger signals from the outdoor operation module (signals emitted when someone rings the doorbell), and respond to these signals by emitting a notification audio to alert the indoor user that a guest has arrived.

[0052] Specifically, by setting a charging unit 140 on the housing 110 and electrically connecting the charging unit 140 to the output terminal of the power input unit 120, the sound output unit 130 can obtain power through the power input unit 120. Thus, when the outdoor operation module is connected to the charging unit 140, the charging unit 140 can provide charging power to the outdoor operation module, ensuring that the outdoor operation module can replenish its power in time when its power is insufficient, and ensuring its normal operation.

[0053] The indoor doorbell module 100 for a smart doorbell provided in this embodiment includes a housing 110, a power input unit 120, a sound output unit 130, and a charging unit 140. Specifically, the charging unit 140 is added to the original structure of the indoor doorbell module 100, and is electrically connected to the output terminal of the power input unit 120. Thus, when the outdoor operating module of the smart doorbell needs to be charged, the outdoor operating module can be removed from the door and brought near the indoor doorbell module 100 for direct charging without the need to search for a separate charging adapter or charger. Therefore, this embodiment improves the charging convenience of the outdoor operating module.

[0054] Furthermore, since the indoor charging module 100 and the outdoor operating module are designed as a set, the charging power generated by the indoor charging module 100 is adapted to the outdoor operating module. This avoids the situation where a mismatch between the charging power of an additional charging head or charger and the outdoor operating module would shorten its battery life. Therefore, this embodiment of the present disclosure can also reduce the risk of shortened battery life of the outdoor operating module due to charging issues.

[0055] Combination Figure 1 and Figure 2As shown, in some embodiments, the power input unit 120 includes a power plug 121 and a power conversion circuit 122. The power plug 121 is disposed in the housing 110 and partially exposed outside the front panel of the housing 110. The input terminal of the power conversion circuit 122 is electrically connected to the power plug 121, and the output terminal serves as the output terminal of the power input unit 120. The power conversion circuit 122 is used to convert 220V AC power into DC power of a set voltage.

[0056] Specifically, by placing the power plug 121 on the housing 110 and partially exposing it on the outside of the front panel of the housing 110, users can easily insert the power plug 121 into an external power socket to connect the indoor Dingdong module 100 to an external power source, thereby introducing the power from the external power source into each unit of the indoor Dingdong module 100.

[0057] Specifically, by electrically connecting the input terminal of the power conversion circuit 122 to the power plug 121, the power conversion circuit 122 can draw in electrical energy from an external power source through the power plug 121 and convert the electrical energy. By using the output terminal of the power conversion circuit 122 as the output terminal of the power input unit 120, the converted electrical energy can be provided to other units within the indoor Dingdong module 100, such as the sound output unit 130 and the charging unit 140.

[0058] Specifically, since the indoor Dingdong module 100 is used in a household electrical environment, the external power supply is 220V AC. However, each unit within the indoor Dingdong module 100 requires DC power to function properly. Therefore, a power conversion circuit 122 is needed to convert the 220V AC power into DC power of a set voltage.

[0059] Optionally, an AC-DC circuit can be used as the power conversion circuit 122.

[0060] Specifically, since the electrical components in different units may require different voltage levels of DC power when operating, the power conversion circuit 122 needs to be able to convert DC power to different voltage levels.

[0061] Optionally, the voltage settings include 5V, 9V, 12V, and 24V.

[0062] In this embodiment, the power plug 121 is used to establish a connection with an external power source and introduce electrical energy. The power conversion circuit 122 is used to convert the introduced electrical energy into DC power suitable for use by each unit in the indoor Dingdong module 100. Together, they constitute the power input unit 120, which provides power guarantee for the normal operation of the entire indoor Dingdong module 100.

[0063] Combination Figure 2As shown, in some embodiments, the sound output unit 130 includes a signal receiving circuit 131 and a speaker 132. The signal receiving circuit 131 is electrically connected to the output of the power conversion circuit 122 and communicatively connected to the outdoor operation module of the smart doorbell. The speaker 132 is electrically connected to the signal receiving circuit 131 and is disposed within the housing 110. When the signal receiving circuit 131 receives a trigger signal from the outdoor operation module, it sends a control signal to the speaker 132 to cause the speaker 132 to emit a notification ringtone.

[0064] Specifically, by electrically connecting the signal receiving circuit 131 to the output terminal of the power conversion circuit 122, the signal receiving circuit 131 can obtain the DC power converted by the power conversion circuit 122, ensuring the normal operation of the signal receiving circuit 131 and its communication connection with the outdoor operation module of the smart doorbell. By communicating with the outdoor operation module of the smart doorbell, the signal receiving circuit 131 can receive the trigger signal from the outdoor operation module, thereby responding to the trigger signal and controlling the speaker 132 to emit a prompt audio, alerting the indoor user to the arrival of a guest.

[0065] Optionally, the signal receiving circuit 131 is a 433MHz OOK receiver. The 433MHz OOK receiver includes an OOK receiver chip and a decoding chip. The OOK receiver chip is used to receive trigger signals from the outdoor operation module based on the 433MHz frequency band wireless signal, demodulate the trigger signals into raw digital signals, and perform amplification and filtering. The decoding chip is used to decode the demodulated digital signal from the OOK receiver chip, extract useful information, and determine whether a control signal needs to be sent to the speaker 132.

[0066] Specifically, by placing the speaker 132 inside the housing 110, a protective space can be provided for the speaker 132, preventing the speaker 132 from being directly interfered with or damaged by the external environment.

[0067] In this embodiment, the signal receiving circuit 131 is responsible for receiving the trigger signal from the outdoor operation module and sending out the control signal, while the speaker 132 receives the control signal and sends out a prompt audio. The two work together to realize the sound prompt function of the indoor Dingdong module 100, allowing users to know in time whether there are guests visiting outside.

[0068] Combination Figure 3 and Figure 5 As shown, in some embodiments, the speaker 132 has a plurality of sound holes 150 on the housing 110 panel facing it.

[0069] Specifically, by opening multiple sound holes 150 on the panel of the housing 110 facing the speaker 132, a propagation channel can be provided for the prompt audio emitted by the speaker 132, so that the sound can be propagated more smoothly from the inside of the housing 110 to the external environment, avoiding excessive reflection or absorption of the sound inside the housing 110, and enhancing the sound propagation effect.

[0070] Optionally, the number and layout of the sound outlets 150 are determined by taking into account the performance of the speaker 132, the size and shape of the housing 110, and the user's needs. For example, for older users who are hard of hearing, the number of sound outlets 150 can be increased to improve sound propagation.

[0071] In this embodiment, by providing multiple sound holes 150 on the housing 110 panel facing the speaker 132, the propagation effect of the notification audio emitted by the indoor ding-dong module 100 is enhanced.

[0072] Combination Figure 2 As shown, in some embodiments, the charging unit 140 includes a wireless charging subunit 141 and / or a wired charging subunit 142. The input terminal of the wireless charging subunit 141 is electrically connected to the output terminal of the power conversion circuit 122, and the output terminal is used to provide charging power to the outdoor operating module. The input terminal of the wired charging subunit 142 is electrically connected to the output terminal of the power conversion circuit 122, and the output terminal is used to cooperate with the charging port of the outdoor operating module to provide charging power to the outdoor operating module.

[0073] Specifically, by electrically connecting the input terminal of the wireless charging subunit 141 to the output terminal of the power conversion circuit 122, the required electrical energy can be obtained from the power conversion circuit 122, and charging power can be provided to the outdoor operation module through wireless charging.

[0074] Specifically, the wireless charging subunit 141 can utilize wireless charging technology (such as electromagnetic induction, magnetic resonance, etc.) to transfer charging energy to the outdoor operating module without the need for a physical connection cable, thereby charging the battery built into the outdoor operating module. This charging method is convenient and fast, reducing the need to plug and unplug the Type-C charging cable 1423 and improving the user experience.

[0075] Specifically, by electrically connecting the input terminal of the wired charging subunit 142 to the output terminal of the power conversion circuit 122, the required electrical energy can be obtained from the power conversion circuit 122, and charging power can be provided to the outdoor operation module through wired charging.

[0076] Specifically, the wired charging subunit 142 can be used with the charging port of the outdoor operating module. When the battery power of the outdoor operating module is low, the user can insert the output terminal of the wired charging subunit 142 into the charging port of the outdoor operating module. Through a physical connection, electrical energy is transferred from the wired charging subunit 142 to the outdoor operating module for charging. This charging method has the advantages of high charging efficiency, improving the charging efficiency and safety of the outdoor operating module.

[0077] In this embodiment, by setting a wireless charging subunit 141 and / or a wired charging subunit 142 in the charging unit 140, users can flexibly choose a suitable charging method according to actual conditions and their own needs, ensuring that the outdoor operation module can be replenished with power in a timely manner to maintain normal working status, thereby improving the user experience.

[0078] Combination Figure 4 and Figure 5 As shown, in some embodiments, the wireless charging subunit 141 includes a wireless charging driver chip 1411 and a wireless coil 1412. The input terminal of the wireless charging driver chip 1411 is electrically connected to the output terminal of the power conversion circuit 122. The wireless coil 1412 is disposed on the inner side of the panel opposite to the panel where the power plug 121 is located on the housing 110, and is electrically connected to the output terminal of the wireless charging driver chip 1411.

[0079] Specifically, the wireless charging driver chip 1411 is the core control component of the wireless charging sub-unit 141. It is used to receive electrical energy from the power conversion circuit 122 and convert the electrical energy into an AC signal suitable for transmission by the wireless coil 1412 according to the preset charging protocol and algorithm.

[0080] Optionally, the wireless charging driver chip 1411 can be Ingenic's IP6808 chip, which supports USB PD / QC fast charging input, with a maximum output power of 15W, and is compatible with Qi1.2.4 / EPP, with a peak efficiency of ≥82% (full-bridge architecture + low-impedance MOS drive).

[0081] Optionally, when using the IP6808 chip as the wireless charging driver chip 1411, a 6.8μH resonant inductor and a 0.22μF resonant capacitor can be used to ensure that the Q value of the IP6808 chip is greater than 80.

[0082] Specifically, by electrically connecting the wireless coil 1412 to the output terminal of the wireless charging driver chip 1411, it can receive the AC signal output by the wireless charging driver chip 1411 and generate an alternating magnetic field around it. When the outdoor operating module approaches, its internal receiving coil will sense this alternating magnetic field and generate an induced current, thereby realizing the wireless transmission of electrical energy and wirelessly charging the outdoor operating module.

[0083] Specifically, by placing the wireless coil 1412 on the inner side of the panel opposite the power plug 121 on the housing 110, it is convenient for the user to place the outdoor operating module close to the wireless coil 1412, allowing for better alignment between the wireless coil 1412 and the receiving coil in the outdoor operating module, thus improving the efficiency and stability of wireless charging. By placing the wireless coil 1412 inside the housing 110, damage to the wireless coil 1412 from the external environment can be prevented, thus protecting the wireless coil 1412.

[0084] Optionally, the wireless coil 1412 is made of Litz wire, which can effectively reduce eddy current losses during wireless charging.

[0085] In this embodiment, a wireless charging sub-unit 141 is formed by the cooperation of the wireless charging driver chip 1411 and the wireless coil 1412, which realizes the wireless charging function of the outdoor operation module, reduces the operation of plugging and unplugging the Type-C charging cable 1423, and improves the user experience.

[0086] Combination Figure 3 As shown, in some embodiments, the indoor Dingdong module 100 further includes a wall mount 160. The wall mount 160 is disposed on the outside of the panel on the housing 110 where the wireless coil 1412 is located, and is used to suspend the outdoor operating module when wirelessly charging the outdoor operating module.

[0087] Specifically, by setting a wall mount 160 on the outside of the panel where the wireless coil 1412 is located on the housing 110, when the outdoor operation module is suspended on the wall mount 160, it can be ensured that the receiving coil in the outdoor operation module and the wireless coil 1412 of the indoor Dingdong module 100 are in a relatively close and suitable position, thereby maximizing the efficiency of wireless charging and reducing energy loss caused by excessive distance or positional deviation.

[0088] Optionally, the wall mount 160 is a snap-on fastener, and the outer casing of the outdoor operating module is provided with a corresponding slot for the snap-on fastener.

[0089] In this embodiment, by setting a wall mount 160 on the outside of the panel where the wireless coil 1412 is located on the housing 110, the outdoor operating module can be suspended and fixed when wirelessly charging, so that the outdoor operating module can remain stable during the charging process, thereby improving the effect of wireless charging of the outdoor operating module.

[0090] For example, such as Figure 6 The diagram shows the outdoor operation module being suspended on the wall mount 160 and charged using the wireless charging subunit 141.

[0091] Combination Figure 1 and Figure 7 As shown, in some embodiments, the wired charging subunit 142 includes: a wired charging driver chip 1421, a USB interface 1422, and / or a Type-C charging cable 1423. The input terminal of the wired charging driver chip 1421 is electrically connected to the output terminal of the power conversion circuit 122. The USB interface 1422 is electrically connected to the output terminal of the wired charging driver chip 1421 or the output terminal of the power conversion circuit 122. The input terminal of the Type-C charging cable 1423 is electrically connected to the output terminal of the wired charging driver chip 1421 or the output terminal of the power conversion circuit 122.

[0092] Specifically, the wired charging driver chip 1421 is the core control component of the wired charging sub-unit 142. It is used to receive electrical energy from the power conversion circuit 122 and adjust and control the electrical energy according to the charging requirements and device characteristics to ensure the safety, efficiency and stability of the charging process.

[0093] Optionally, the wired charging driver chip 1421 can be the SC9712A chip from Southchip Technology, the SW2335 / SW2337 chip from Zhirong Technology, or the HUSB381 chip from Huinengtai, but is not limited to these.

[0094] Specifically, two charging paths are provided for the USB interface 1422: one is to regulate the power through the wired charging driver chip 1421 and then output it to the USB interface 1422; the other is to directly obtain power from the power conversion circuit 122 and output it to the USB interface 1422.

[0095] Specifically, the USB interface 1422 is a universal charging USB interface 1422, and users can connect it to a universal USB Type-A to Micro USB, Type-C, or Lightning USB interface 1422 Type-C charging cable 1423 according to their needs. In this way, in addition to using the indoor Dingdong module 100 to charge the outdoor operating module, the indoor charging module can also be used as an emergency charging head when the user cannot find a charging head.

[0096] Specifically, the Type-C charging cable 1423 can either obtain power directly from the power conversion circuit 122, or be charged after being regulated by the wired charging driver chip 1421.

[0097] Specifically, the Type-C charging cable 1423 is plugged into the USB interface 1422 or directly connected to the charging port of the outdoor operating module via the Type-C charging cable 1423. Then, the power conversion circuit 122 converts the input power into suitable electrical energy and delivers it to the wired charging driver chip 1421 or directly to the USB interface 1422 or the Type-C charging cable 1423 to realize wired charging of the outdoor operating module.

[0098] In this embodiment, a wired charging subunit 142 is formed through the coordinated operation of the wired charging driver chip 1421, the USB interface 1422 and / or the Type-C charging cable 1423, which realizes the wired charging function of the outdoor operation module and ensures the safety and stability of the charging process.

[0099] For example, such as Figure 8 The diagram shown illustrates the use of a Type-C charging cable 1423 to charge the outdoor operating module.

[0100] In some embodiments, the indoor whistle module 100 further includes an energy storage battery. The energy storage battery is disposed inside the housing 110, with its input terminal electrically connected to the output terminal of the power input unit 120 and its output terminal electrically connected to the input terminal of the charging unit 140.

[0101] Specifically, by placing the energy storage battery inside the casing 110, damage to the energy storage battery from external impacts, pressure, etc., can be prevented, thus protecting the energy storage battery.

[0102] Specifically, by electrically connecting the input terminal of the energy storage battery to the output terminal of the power input unit 120 and the output terminal to the input terminal of the charging unit 140, when the outdoor operation module is not convenient to be removed from the door, the indoor Dingdong module 100 can be moved outdoors to charge the outdoor operation module.

[0103] Combination Figure 9 As shown, this embodiment of the disclosure provides a smart doorbell 10, including: an outdoor operation module 200 and an indoor doorbell module 100 as described above. The outdoor operation module 200 is installed on the door. The indoor doorbell module 100 is communicatively connected to the outdoor operation module 200.
