Additionally, the indoor unit 10 may include an antenna for communication with the doorbell outdoor unit. Thus, after the outdoor unit acquires visitor information via its installed camera, it can transmit the visitor's image information to the doorbell indoor unit 100, allowing indoor occupants to observe the visitor through the indoor unit. Of course, in some embodiments, to enable video functionality between the indoor doorbell unit 100 and the outdoor doorbell unit, the indoor unit body 10 may also include a camera for capturing user image information and transmitting that image information to the outdoor doorbell unit. Furthermore, to enable voice functionality, both the indoor doorbell unit 100 and the outdoor doorbell unit may also be equipped with a microphone and a speaker. Since the working principle of the indoor doorbell unit 100 and the outdoor doorbell unit is prior art, their specific structures will not be described in detail here. Additionally, on the projection surface perpendicular to the display surface 111, the indoor unit body 10 may be rectangular, square, or circular, etc.; this application does not limit the shape of the indoor unit body 10.

[0051] The first frame 20 provides a mounting position for the indoor unit 10, allowing it to be stably placed on a support surface such as a table. The first frame 20 can be any shape, such as L-shaped, T-shaped, V-shaped, square, or rectangular. The second frame 30 also provides a mounting position for the indoor unit 10. Furthermore, the second frame 30 can be used to mount the second frame 30 onto a wall or door support surface. The second frame 30 can also be any shape, such as L-shaped, T-shaped, V-shaped, square, or rectangular. The indoor unit body 10 can be selectively and detachably installed on either the first frame 20 or the second frame 30. That is, the indoor unit body 10 can be installed on either the first frame 20 or the second frame 30, and can be removed regardless of which frame it is installed on. The detachable connection method of the indoor unit body 10 on the first frame 20 can be any connection method such as plug-in connection, screw connection, magnetic connection, or snap-on connection. The detachable connection method of the indoor unit body 10 on the second frame 30 can also be any connection method such as plug-in connection, screw connection, magnetic connection, or snap-on connection. Furthermore, the detachable connection methods of the indoor unit body 10 on the first frame 20 and the second frame 30 can be the same or different.

[0052] The doorbell indoor unit 100 of this application is configured with a first frame 20 and a second frame 30, and a mounting structure 31 is provided on the second frame 30. The indoor unit 10 can be installed on the first frame 20, which can be placed on a support surface such as a desktop, thus allowing the indoor unit 10 to be used on a horizontal support surface. Alternatively, the indoor unit 10 can be installed on the second frame 30, which can be mounted on a support surface such as a wall or door via the mounting structure 31, thus allowing the indoor unit 10 to be used on a vertical support surface such as a wall or door. Therefore, the structural design of the doorbell indoor unit 100 in this solution is compatible with the installation and use of the doorbell indoor unit 100 in a variety of scenarios, enriching the installation and use scenarios of the doorbell indoor unit 100, and thus improving the flexibility of its use.

[0053] Please refer to the reference. Figures 8 to 10In one embodiment of this application, the second frame 30 may be provided with a first through hole 311, which forms a mounting structure 31. Screws can pass through the first through hole 311 to secure the second frame 30 to a wall or door. Screw connections are simple and reliable, thus improving the convenience and stability of mounting the second frame 30 and simplifying its structural design. In another embodiment of this application, the second frame 30 may be provided with an adhesive member 312, which forms the mounting structure 31. The second frame 30 can be adhered to a wall or door using the adhesive member 312. Adhesive bonding increases the connection area, thereby improving the stability of the mounting installation. Furthermore, a connection structure is needed between the second frame 30 and the wall or door to protect both the second frame 30 and the wall or door from damage. The adhesive component 312 can be 3M adhesive, such as VHB tape or double-sided foam tape. Of course, in some embodiments, the adhesive component 312 can also be glue; this application does not limit the type of adhesive component 312. Furthermore, it should be noted that the second frame 30 can have a single first through hole 311, a single adhesive component 312, or both, allowing users to choose according to their specific needs and improving the flexibility of mounting the second frame 30. In addition, in some embodiments, hooks can be provided on the second frame 30 for hook-and-loop connection with hooks on walls or doors; this application does not limit the type of mounting structure 31.

[0054] Please refer to the reference. Figures 3 to 6 ,as well as Figure 8 and Figure 9 In one embodiment of this application, the casing 11 of the indoor unit body 10 is provided with a groove 1131, the first frame 20 is provided with a first protrusion 2312, and the second frame 30 is provided with a second protrusion 3311. When the indoor unit body 10 is installed on the first frame 20, the first protrusion 2312 is inserted into the groove 1131 so that the indoor unit body 10 can be detachably installed on the first frame 20. When the indoor unit body 10 is installed on the second frame 30, the second protrusion 3311 is inserted into the groove 1131 so that the indoor unit body 10 can be detachably installed on the second frame 30.

[0055] The groove 1131 can be any shape, such as square, rectangle, or circle. Additionally, the casing 11 of the indoor unit body 10 can also have a back surface 112 facing away from the display surface 111, and a mounting surface 113 connecting the display surface 111 and the back surface 112. When the indoor unit body 10 is in normal installation and use, the mounting surface 113 can be located on the bottom side of the indoor unit body 10. In this case, the groove 1131 can be provided on the mounting surface 113, or it can be provided on the back surface 112; this application does not limit the location of the groove 1131 on the indoor unit body 10. The first boss 2312 and the second boss 3311 can have the same shape as the groove 1131, so as to realize the insertion connection of the indoor unit body 10 on the first frame 20 and the second frame 30, respectively.

[0056] In this embodiment, the groove 1131 provided on the indoor unit body 10 can serve as a universal connection structure. That is, by the insertion and engagement of the groove 1131 with the first boss 2312 and the second boss 3311, installation on the first frame 20 and the second frame 30 can be achieved respectively. This reduces the number of connection structures required for the indoor unit body 10, and the structures of the groove 1131, the first boss 2312, and the second boss 3311 are relatively simple, which helps to simplify the respective structures of the indoor unit body 10, the first frame 20, and the second frame 30, improves the convenience of their processing and manufacturing, and also improves the convenience of disassembly and assembly.

The charging part 2313 is connected to a power transmission line 2314. When the indoor unit body 10 is installed on the first frame 20, the charging part 2313 and the conductive part 1132 are connected and connected.

[0058] The conductive part 1132 and the charging part 2313 can be a Pogopin female and a Pogopin male, respectively. Alternatively, the conductive part 1132 and the charging part 2313 can be two metal pillars. This application does not limit the type of the conductive part 1132 and the charging part 2313, as long as it ensures that when the indoor unit body 10 is installed on the first frame 20, the conductive part 1132 and the charging part 2313 can be connected and conduct electricity after the first boss 2312 and the groove 1131 are plugged in. The power transmission line 2314 can be connected at one end to the end of the charging part 2313 away from the electrically connected conductive part 1132, and the other end can be provided with a plug for connection to an external power source. To reduce the impact of the power transmission line 2314 on the placement of the first frame 20 on a table or other supporting surface, the power transmission line 2314 can be embedded in the second frame 30 and led out from the side of the second frame 30.

[0059] In this embodiment, the conductive part 1132 and the charging part 2313 are provided so that after the indoor unit body 10 is installed on the first frame 20, the indoor unit body 10 can be charged through the first frame 20, thus eliminating the need to remove the indoor unit body 10 for charging, which improves the convenience of using the indoor unit body 10. Furthermore, the conductive part 1132 and the charging part 2313 are respectively provided in the groove 1131 and the first protrusion 2312, so that the cooperation between the groove 1131 and the first protrusion 2312 can guide the docking of the conductive part 1132 and the charging part 2313, so that they can accurately dock during the installation of the indoor unit body 10 on the second frame 30 without additional docking operations, improving the convenience of charging the indoor unit body 10. At the same time, the conductive part 1132 and the charging part 2313 can also be concealed, improving their protection and thus enhancing the safety of charging the indoor unit body 10.

[0060] Please refer to the reference. Figures 3 to 6 In one embodiment of this application, the mounting surface 113 is provided with a groove 1131, and the first frame 20 has a first support surface 211 and a second support surface 231 that are connected and set at an angle. The second support surface 231 is provided with a first boss 2312 and a first stop rib 2317. When the indoor unit body 10 is installed on the first frame 20, the back surface 112 is attached to the first support surface 211, the mounting surface 113 is attached to the second support surface 231, and the first stop rib 2317 abuts against the side of the indoor unit body 10 with the display surface 111.

[0061] In this embodiment, the first support surface 211 and the second support surface 231 can respectively support the back and bottom of the indoor unit body 10, and the stop ribs abut and limit the movement at the front of the bottom of the indoor unit body 10, which helps to improve the stability of the indoor unit body 10 when installed on the first frame 20. The display surface 111 can have a display area and a non-display area, and the stop ribs can abut against the non-display area. Furthermore, the first stop rib 2317 can extend into a long strip along the intersection line of the first support surface 211 and the second support surface 231 to increase the contact area with the indoor unit body 10 and improve the stopping effect. Alternatively, the first stop rib 2317 can extend into a columnar structure in the vertical direction, in which case at least two first stop ribs 2317 can be provided along the intersection line of the first support surface 211 and the second support surface 231. Furthermore, in order to provide users with a better viewing angle for the indoor unit installed on the first frame 20, the first support surface 211 can be inclined and facing forward and upward, and the second support surface 231 can be inclined and facing backward and upward, so that the indoor unit body 10 installed on the first frame 20 can also be installed at an angle.

[0062] Please refer to the reference. Figures 4 to 6In one embodiment of this application, the second support surface 231 can be configured to mimic the shape of the mounting surface 113, that is, the shape of the second support surface 231 and the shape of the mounting surface 113 are set to be the same, so as to improve the tightness of their fit, thereby improving the stability of the indoor unit installed on the first frame 20. For example, the mounting surface 113 may include a first surface 1134, a second surface 1135 and a third surface 1136. The first surface 1134 may be connected to the back surface 112, the third surface 1136 may be connected to the display surface 111, the second surface 1135 may be connected to the first surface 1134 and the third surface 1136, and is set at an angle to both the first surface 1134 and the third surface 1136. The groove 1131 may be provided on the first surface 1134. Correspondingly, the second support surface 231 may include a fourth surface 2311, a fifth surface 2315 and a sixth surface 2316. The fourth surface 2311 is connected to the first support surface 211, and the sixth surface 2316 and the fourth surface 2311 are oriented in the same direction. Similarly, the fifth surface 2315 connects the fourth surface 2311 and the sixth surface 2316, and is set at an angle to both the fourth surface 2311 and the sixth surface 2316. The first boss 2312 can be set on the fourth surface 2311, and the first stop rib 2317 can be set on the sixth surface 2316. When the indoor unit body 10 is installed on the first frame 20, the first surface 1134 can be attached to the fourth surface 2311, the second surface 1135 can be attached to the fifth surface 2315, and the third surface 1136 can be attached to the sixth surface 2316, so that the mounting surface 113 and the second support surface 231 can form a stepped attachment, which is conducive to improving the limiting support effect of the indoor unit body 10.

[0065] In this embodiment, the back and bottom of the indoor unit body 10 can be supported by the third support surface 321 and the fourth support surface 331 respectively, and the indoor unit body 10 can be clamped and limited on the opposite sides by the two clamping surfaces 341, which helps to improve the stability of the indoor unit body 10 when installed on the second frame 30.

[0066] Please refer to the reference. Figure 8 and Figure 9 In one embodiment of this application, the clamping surface 341 may be provided with a second stop rib 3411, and the side surface 114 may be provided with a stop groove 1141. When the indoor unit body 10 is installed on the second frame 30, the second stop rib 3411 is inserted into the stop groove 1141, so as to improve the stability of the indoor unit body 10 on the second frame 30 through the cooperation of the second stop rib 3411 and the stop groove 1141. Moreover, in order to facilitate the bracket installation of the indoor unit body 10 on the second frame 30, the lower end of the stop groove 1141 may be open, so that the indoor unit body 10 can be inserted and installed on the second frame 30 from top to bottom.

[0067] Please refer to Figure 9 In one embodiment of this application, in order to simplify the structural configuration of the second frame 30 and reduce manufacturing costs, the second frame 30 may include a fourth plate 32, a fifth plate 33, and a sixth plate 34. A third support surface 321 may be provided on one side of the fourth plate 32; the fifth plate 33 is connected to the bottom of the fourth plate 32 and extends along the side facing the third support surface 321, and the upper surface of the fifth plate 33 may form a fourth support surface 331; two sixth plates 34 may be located at both ends of the intersection line of the fourth plate 32 and the fifth plate 33 and connected to the fourth plate 32 and the fifth plate 33, and the two opposing surfaces of the two sixth plates 34 form a clamping surface 341.

[0068] Please refer to the reference. Figure 4 and Figure 5 ,as well as Figures 8 to 10In one embodiment of this application, a first cat-eye electrical connector 1133 is embedded in the groove wall corresponding to its opening in the groove 1131, and a second cat-eye electrical connector 3312 is provided on the second boss 3311; when the indoor unit body 10 is installed on the second frame 30, the second cat-eye electrical connector 3312 is connected to the first cat-eye electrical connector 1133.

[0069] The first peephole electrical connector 1133 and the second peephole electrical connector 3312 can be a USB female connector and a USB interface, respectively, or other types of connectors. Furthermore, when the conductive part 1132 described above is also embedded in the groove wall corresponding to the opening of the recess 1131, the first peephole electrical connector 1133 and the conductive part 1132 need to be spaced apart and both electrically connected to the circuit board of the indoor unit body 10. In addition, the second peephole electrical connector 3312 can also connect a data cable 3313, such as a ribbon cable, to electrically connect to the peephole.

[0070] In this embodiment, when the second frame 30 is mounted on the rear side of the door, the cooperation between the second peephole electrical connector 3312 and the first peephole electrical connector 1133 allows the indoor unit 10 mounted on the second frame 30 to be electrically connected to the peephole mounted on the front side of the door via the second peephole electrical connector 3312. This enables signal transmission between the peephole and the indoor unit 10, allowing the user to observe the outdoor environment through the peephole's camera. Furthermore, the second peephole electrical connector 3312 is detachably mounted on the second frame 30, allowing the user to choose whether or not to use it. That is, when signal transmission with the outdoor peephole is not required, the second peephole electrical connector 3312 can be removed from the second frame 30, reducing the impact of the data cable 3313 connected to the second peephole electrical connector 3312 on the installation of the second frame 30 on the wall or door support surface.

[0071] Please refer to the reference. Figures 9 to 12 In one embodiment of this application, the second frame 30 also has a rear back surface 3219 facing away from the third support surface 321. The second frame 30 is provided with a first mounting groove 35. One end of the first mounting groove 35 is provided on the second boss 3311, and the other end extends through the rear back surface 3219 to form an insertion port 351. The second cat-eye electrical connector 3312 is installed in the first mounting groove 35 through the insertion port 351.

[0072] In this embodiment, the first mounting slot 35 is provided so that the second cat-eye electrical connector 3312 can be directly inserted into the first mounting slot 35 through the insertion port 351 on the back side of the second frame 30. This simplifies the installation structure of the second cat-eye electrical connector 3312, thereby improving the convenience of assembling and disassembling the second cat-eye electrical connector 3312, as well as the convenience of manufacturing the second frame 30.

[0073] Please refer to the reference. Figures 13 to 15 In one embodiment of this application, the cross-section of the upper end of the first mounting groove 35 is smaller than that of the lower end, such that the groove wall of the first mounting groove 35 may include a bottom wall 353 and a top wall 352. The orientation of the bottom wall 353 is the same as that of the fourth support surface 331. The top wall 352 and the bottom wall 353 are arranged opposite to each other, and a portion of the second cat-eye electrical connector 3312 is engaged between the bottom wall 353 and the top wall 352. At this time, the bottom wall 353 and the top wall 352 clamp and limit the second cat-eye electrical connector 3312, which is beneficial to improving the convenience of installing the second cat-eye electrical connector 3312 on the second frame 30. In addition, the first through hole 311 described above can penetrate the third support surface 321 and the rear back surface 3219, and the adhesive 312 can be adhered to the rear back surface 3219. Furthermore, the first through hole 311 can be countersunk so that it will not protrude from the third support surface 321 after the screws are installed, thus not affecting the installation of the indoor unit body 10.

[0074] Please refer to the reference. Figure 9 and Figure 10 In one embodiment of this application, the third support surface 321 is provided with a second mounting groove 3211, and a mounting plate 3212 is provided in the second mounting groove 3211. The mounting plate 3212 is provided with a second through hole 3213. The second frame 30 is provided with a clearance hole 3215 at the position corresponding to the second through hole 3213, which connects to the second mounting groove 3211 and penetrates the rear back 3219. The third support surface 321 is also provided with a third mounting groove 3216 that connects the second mounting groove 3211 and the first mounting groove 35. A cover plate 3217 is provided in the third mounting groove 3216. One end of the cover plate 3217 is located in the second mounting groove 3211 and covers the mounting plate 3212. The other end extends into the first mounting groove 35 and cooperates with the groove wall of the corresponding insertion port 351 of the first mounting groove 35 to clamp the second cat's eye electrical connector 3312.

[0075] In this embodiment, the second mounting groove 3211 can be located above the first mounting groove 35. The mounting plate 3212 can be made of sheet metal or other metal parts to increase the structural strength of the mounting plate 3212. This facilitates the insertion of screws through the second through hole 3213 on the mounting plate 3212 into the through hole of the door body, allowing for a high-strength tightening of the screws with the studs inserted into the through hole of the peephole installed on the front side of the door body. This improves the stability of the mechanical connection to the peephole without damaging the structure of the mounting plate 3212. Furthermore, the peephole is installed on the inner side, preventing it from being disassembled. The cover plate 3217 provides a protective cover for the mounting plate 3212 and, through its lower end, stops and limits the insertion of the second peephole electrical connector 3312 into the first mounting groove 35, reducing the possibility of the second peephole electrical connector 3312 detaching from the insertion port 351. Moreover, at this time, in other words, the second cat-eye electrical connector 3312 can also act as an abutment limiter on the lower end of the cover plate 3217, thereby achieving mutual limitation between the second cat-eye electrical connector 3312 and the cover plate 3217.

[0076] Please refer to the following: Figures 9 to 13 A first latch 3214 may be provided in the second mounting groove 3211 to pass through the first opening 3212a of the mounting plate 3212 and engage with the mounting plate 3212. A second latch 3218 may be provided in the cover plate 3217 to pass through the second hole of the mounting plate 3212 and engage with the rear back 3219 of the second frame 30. In addition, there may be two first through holes 311 as described above, distributed on both sides of the third mounting groove 3216, so that the components do not interfere with each other and the force uniformity of the indoor unit body 10 can be improved.

[0077] Please refer to the reference. Figures 16 to 18 In one embodiment of this application, the indoor unit body 10 further includes a folding frame 13, and a storage slot 1121 is provided on the back side 112; the folding frame 13 is rotatably disposed in the storage slot 1121 and has a folded state and an unfolded state. In the folded state, the folding frame 13 is housed in the storage slot 1121, and in the unfolded state, the folding frame 13 and the housing 11 are arranged at an angle.

[0078] In this embodiment, by setting up a folding frame 13, the indoor unit body 10 can be stably placed on a support surface such as a table by unfolding the folding frame 13 when it is not installed on the first frame 20 and the second frame 30.

[0079] Please refer to the reference. Figures 9 to 26In one embodiment of this application, the housing 11 is provided with a shaft hole 115, a first limiting protrusion 116, and a second limiting protrusion 117. The bracket may be provided with an elastic arm 131, and the elastic arm 131 may be provided with a rotating shaft 1311, so that the bracket can be inserted into the shaft hole 115 through the rotating shaft 1311 on the elastic arm 131, thereby realizing the rotational installation of the bracket. In the folded state, the elastic arm 131 abuts against the side of the first limiting protrusion 116 away from the second limiting protrusion 117 to prevent the bracket from rotating to the unfolded state; in the unfolded state, the elastic arm 131 is engaged between the first limiting protrusion 116 and the second limiting protrusion 117.

[0080] In this embodiment, the housing 11 and the bracket are directly rotatably connected by inserting a pivot 1311 into the shaft hole 115. Simultaneously, in the folded state, the elastic arm 131 abuts against the side of the first limiting protrusion 116 away from the second limiting protrusion 117, preventing the bracket from rotating to the unfolded state, thus limiting the bracket in the folded state. In the unfolded state, utilizing the deformability of the elastic arm 131, it can engage between the first limiting protrusion 116 and the second limiting protrusion 117, thus limiting the bracket in the unfolded state. Since the elastic arm 131 and the limiting protrusion assembly are also directly provided on the housing 11 and the bracket, the bracket can achieve stable folded and unfolded states using only the housing 11 and the bracket, thereby reducing the number of parts in the indoor unit body 10 and simplifying the assembly process.

[0081] In one embodiment of this application, the elastic arm 131 extends along a first direction, and the rotating shaft 1311 extends along a second direction intersecting the first direction. At least one of the elastic arm 131 and the first limiting protrusion 116 is provided with a first guide surface 14, which is configured to guide the elastic arm 131 to deform along the second direction, so that the elastic arm 131 can rotate to engage between the first limiting protrusion 116 and the second limiting protrusion 117; at least one of the elastic arm 131 and the first limiting protrusion 116 is also provided with a second guide surface 15, which is configured to guide the elastic arm 131 to deform along the second direction, so that the elastic arm 131 can rotate out of the first limiting protrusion 116 and the second limiting protrusion 117.

[0082] In this embodiment, when the bracket is in the unfolded state and the indoor unit 10 is normally placed on a support surface such as a table, the first direction can be an inclined direction, and the second direction can be a horizontal direction. The elastic arm 131 is guided by the first guide surface 14 or the second guide surface 15 to deform along the second direction during rotation. The elastic arm 131 has a greater deformation capacity in the second direction, thus facilitating the deformation of the elastic arm 131 as it follows the rotation of the bracket, thereby switching the state of the bracket. The first guide surface 14 can be a rounded corner structure, or it can be an angled structure. Furthermore, it should be noted that the deformation distance of the elastic arm 131 along the second direction during the rotation of the bracket needs to be less than the distance the rotating shaft 1311 inserts into the shaft hole 115, to avoid the elastic arm 131 causing the rotating shaft 1311 to detach from the shaft hole 115 during deformation. In one embodiment of this application, instead of providing the elastic arm 131, a rotating shaft 1311 can be directly provided on the bracket, and an elastic sleeve, such as a silicone sleeve or a rubber sleeve, can be provided between the rotating shaft 1311 and the shaft hole 115 to provide damping friction force, thereby achieving the limiting and fixing of the bracket in different states.
