Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0024] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple.

[0025] The technical solutions disclosed in each embodiment of the present application will be described in detail below with reference to the drawings.

[0026] Please refer to Figures 1 to 10 , an indoor unit 100 is disclosed in an embodiment of the present application. The disclosed indoor unit 100 may include an indoor unit main body 110 and an adapter 120. The indoor unit main body 110 can implement functions such as communication interaction, screen display, voice playback and collection, or intelligent control. For example, a display module can be provided on the indoor unit main body 110, and users can perform operations such as visual intercom and human - machine interaction through the display module. In a specific usage scenario of the present application, the indoor unit 100 can be applied to building and medical intercom systems. For example, a building intercom system can include an access control controller, an outdoor unit, and the above - mentioned indoor unit 100, etc. The indoor unit 100 can be installed on the wall of a user's home and interconnected with the outdoor unit through a transmission network to achieve functions such as visual intercom and access control. Or, the door machine in a medical interaction system can also be referred to as a kind of "indoor unit".

[0027] The adapter 120 mainly serves as a bridge between the junction box 200 and the indoor unit main body 110. On the one hand, the adapter 120 can achieve the installation and fixation of the indoor unit main body 110 at the structural level. On the other hand, the adapter 120 can conduct the circuit between the junction box 200 and the indoor unit main body 110.

[0028] It should be noted that the junction box 200 can be embedded inside a load-bearing object such as a wall. The weak current circuit and the strong current circuit inside the junction box 200 can be electrically connected to the indoor unit main body 110 through the adapter 120, so as to provide power supply and communication functions for the indoor unit main body 110. Specifically, the indoor unit main body 110 can include a housing 111, and devices such as a display module and a circuit board are arranged on the housing 111. A first installation part 112 and a first electrical connection part 113 are also arranged outside the housing 111. The first installation part 112 and the first electrical connection part 113 can be specifically arranged on one side of the housing 111 facing away from the display module. The first electrical connection part 113 passes through the housing 111 and is connected to the circuit board inside the housing 111. The adapter 120 is provided with a second installation part 121 and a second electrical connection part 122. When the first installation part 112 and the second installation part 121 are connected to each other, it can drive the first electrical connection part 113 and the second electrical connection part 122 to be electrically connected, so as to realize the structural fixation and circuit conduction of the indoor unit main body 110.

[0029] Since the first electrical connection part 113 and the second electrical connection part 122 are arranged opposite to each other, in the above installation process, only the alignment operation needs to be carried out during the connection process of the first installation part 112 and the second installation part 121. The first electrical connection part 113 and the second electrical connection part 122 can be smoothly electrically connected on the basis of the above alignment operation without corresponding alignment steps, thus simplifying the installation steps.

[0030] The connection method between the above first installation part 112 and the second installation part 121 can include snap connection, bolt connection, etc. The electrical connection method between the first electrical connection part 113 and the second electrical connection part 122 can include plug connection, abutting connection, etc. The indoor unit main body 110 needs to be conductively connected to the junction box 200 through the adapter 120. For the connection relationship between the adapter 120 and the junction box 200, such as Figure 7 and Figure 8As shown, one side of the adapter 120 facing away from the second electrical connection part 122 is connected to the junction box 200, and the second electrical connection part 122 is electrically connected to the junction box 200, so that the indoor unit main body 110 can be fixed to the junction box 200 through the adapter 120 and is electrically connected to the junction box 200. The connection method between the adapter 120 and the junction box 200 may include snap connection, bolt connection, etc. A wiring structure may be provided on the side of the adapter 120 facing the junction box 200. The weak current circuit and the strong current circuit in the junction box 200 can be conducted through the wiring structure, the second electrical connection part 122 and the first electrical connection part 113.

[0031] It should be added that a communication module and an AC-DC module are provided on the adapter 120. The AC-DC module and the communication module are respectively connected to the second electrical connection part 122. The weak current circuit and the strong current circuit in the junction box 200 can be respectively connected to the second electrical connection part 122 through the communication module and the AC-DC module, and then conducted to the first electrical connection part 113 and the indoor unit main body 110.

[0032] As can be seen from the above, the indoor unit 100 disclosed in the embodiment of the present application improves the related art. When the first installation part 112 and the second installation part 121 are connected to each other, the electrical connection between the first electrical connection part 113 and the second electrical connection part 122 can be realized synchronously. That is, the structural connection and the electrical connection of the indoor unit main body 110 can be completed synchronously without multiple alignment operations, thus simplifying the installation process and improving the installation efficiency.

[0033] As Figures 1 to 6 shown, the first installation part 112 may include a first groove 1121 provided on the housing 111, and the first electrical connection part 113 is provided in the first groove 1121. The second installation part 121 includes a frame body 1211 provided at the edge of the adapter 120. When the housing 111 is connected to the adapter 120, at least part of the frame body 1211 extends into the first groove 1121 and is in positioning cooperation with the first groove 1121, so as to facilitate the alignment installation of the indoor unit main body 110 and the adapter 120. The positioning cooperation between the frame body 1211 and the first groove 1121 is actually realized through the positioning contact between the side of the frame body 1211 and the groove wall of the first groove 1121; and, under the mutual limiting action of the frame body 1211 and the first groove 1121, the large-amplitude shaking between the indoor unit main body 110 and the adapter 120 can also be avoided, improving the stability of the installation. The directions of mutual limitation between the frame body 1211 and the first groove 1121 may include the horizontal direction and the vertical direction.

[0034] Please continue to refer to Figures 1 to 6, the first mounting portion 112 may further include a boss 1122 provided at the bottom of the first groove 1121, the first electrical connection portion 113 is provided on the boss 1122, and the first groove 1121 and the boss 1122 may be formed on the housing 111 by an integrally formed casting method, or may be separately manufactured and then fixed to the housing 111 by means such as bonding and welding. The second mounting portion 121 may further include a second groove 1212 provided on the adapter 120, the second electrical connection portion 122 is provided in the second groove 1212, and the frame body 1211 is disposed around the second groove 1212. Similarly, the adapter 120 may also form the frame body 1211 and the second groove 1212 by an integrally formed casting method, or form the frame body 1211 and the second groove 1212 by means such as bonding and welding.

[0035] When the indoor unit main body 110 and the adapter 120 are assembled, the groove wall of the second groove 1212 can be positioned and matched with the edge of the boss 1122. When at least a part of the boss 1122 extends into the second groove 1212, the first electrical connection portion 113 can be electrically connected to the second electrical connection portion 122. The positioning and matching between the boss 1122 and the second groove 1212 is actually realized by the positioning contact between the side of the boss 1122 and the groove wall of the second groove 1212; and, under the mutual limiting action of the boss 1122 and the second groove 1212, it can also prevent large-amplitude shaking between the indoor unit main body 110 and the adapter 120, improving the stability of installation.

[0036] The indoor unit main body 110 and the adapter 120 can be assembled by means such as snap connection and bolt connection. Taking snap connection as an example, a first snap 1123 can be provided on one of the first groove 1121 and the frame body 1211, and a card slot 1213 can be provided on the other of the first groove 1121 and the frame body 1211. When the first groove 1121 and the frame body 1211 are butted, the first snap 1123 and the card slot 1213 are snap-connected to each other, thereby performing snap connection and assembly on the indoor unit main body 110 and the adapter 120.

[0037] In a specific implementation manner of the present application, as Figure 4 shown, a card slot 1213 can be provided at the edge of the frame body 1211, Figure 6 shows a relatively small indoor unit main body 110 according to an embodiment of the present application. A first snap 1123 can be provided on the inner side of the groove wall of the first groove 1121. When the first groove 1121 and the frame body 1211 are butted, the first snap 1123 and the card slot 1213 can be snap-connected to each other. The number of the first snaps 1123 and the card slots 1213 is equal and they are arranged in one-to-one correspondence. The specific number can be selected according to the size of the indoor unit main body 110.

[0038] For other snap - fitting methods between the indoor unit main body 110 and the adapter 120, for example, as Figure 2 and Figure 5 show two indoor unit main bodies 110 with larger sizes in the embodiments of the present application. Second snap - fasteners 1124 can be provided at the edge of the boss 1122. As Figure 4 shown, third snap - fasteners 1214 can be provided on the groove wall of the second groove 1212. The second snap - fasteners 1124 and the third snap - fasteners 1214 can be elastic snap - fasteners. When the boss 1122 is docked with the second groove 1212, the second snap - fasteners 1124 and the third snap - fasteners 1214 can be snap - fitted with each other, so as to perform snap - fitting assembly on the indoor unit main body 110 and the adapter 120. The number of the second snap - fasteners 1124 and the third snap - fasteners 1214 is equal and they are arranged in one - to - one correspondence. The specific number can be selected according to the size of the indoor unit main body 110.

[0039] The cooperation between the above - mentioned first snap - fastener 1123 and the card slot 1213, and the cooperation between the second snap - fastener 1124 and the third snap - fastener 1214 can be used alone or in combination. Moreover, with the above - mentioned snap - fitting design, the adapter 120 can be adapted to indoor unit main bodies 110 of different sizes, with strong versatility, which can reduce the development cost.

[0040] In some usage scenarios, it is necessary to remove the indoor unit main body 110 from the adapter 120. To facilitate the disassembly of the indoor unit main body 110, as Figure 1 , Figure 2 , Figures 4 to 6 shown, a notch 1125 can be provided on the groove wall of the first groove 1121, and a protruding easy - to - disassemble structure 1215 can be provided on the edge of the frame 1211. When the frame 1211 is docked with the first groove 1121, the easy - to - disassemble structure 1215 can extend into the notch 1125, and there is an assembly gap between the easy - to - disassemble structure 1215 and the notch 1125. The easy - to - disassemble structure 1215 can be a columnar protrusion, a sheet - like protrusion, etc. During disassembly, a tool can be used to extend into the assembly gap between the easy - to - disassemble structure 1215 and the notch 1125, and the indoor unit main body 110 or the adapter 120 can be pried up with the easy - to - disassemble structure 1215 as a fulcrum, so as to facilitate the separation of the indoor unit main body 110 and the adapter 120.

[0041] As Figure 9 and Figure 10 shown, a chamfer 1126 structure is provided on at least one of the second snap - fasteners 1124 and the third snap - fasteners 1214. During the installation and separation of the second snap - fasteners 1124 and the third snap - fasteners 1214, the chamfer 1126 structure can prevent destructive contact between the second snap - fasteners 1124 and the third snap - fasteners 1214, thereby improving the durability of use and also facilitating the installation and disassembly of the indoor unit main body 110 and the adapter 120.

[0042] AsFigures 4 to 6 As shown, the first electrical connection part 113 and the second electrical connection part 122 can be electrically connected by plugging. One of the first electrical connection part 113 and the second electrical connection part 122 can be a male electrical connection port, and the other can be a female electrical connection port. The male electrical connection port can be plugged and matched with the female electrical connection port to achieve electrical connection. In addition, the first electrical connection part 113 and the second electrical connection part 122 can also be electrically connected by magnetic attraction. The present application does not limit the electrical connection method between the first electrical connection part 113 and the second electrical connection part 122.

[0043] As Figures 4 to 6 shown, the first electrical connection part 113 and the second electrical connection part 122 are respectively provided with a strong electrical connection area and a weak electrical connection area. The two strong electrical connection areas are correspondingly connected, and the two weak electrical connection areas are correspondingly connected. Since the strong electrical connection area and the weak electrical connection area are integrated on the same pair of interfaces, that is, the cooperation between the first electrical connection part 113 and the second electrical connection part 122 can simultaneously realize the conduction of strong electricity and weak electricity, further simplifying the steps of electrical connection and being beneficial to improving the installation efficiency of the indoor unit main body 110. The strong electrical connection area and the weak electrical connection area provided in the second electrical connection part 122 are respectively electrically connected to the junction box 200. Specifically, the strong electrical connection area can be connected to the strong electrical circuit of the junction box 200 through an AC-DC module, and the weak electrical connection area can be connected to the weak electrical circuit of the junction box 200 through a communication module.

[0044] To improve the structural strength of the adapter 120, as Figure 4 and Figure 7 shown, connection ribs 1216 can be provided between the frame body 1211 and the groove wall of the second groove 1212. The connection ribs 1216, the frame body 1211, and the second groove 1212 can be made by integral molding, or can be made separately and then assembled together by bonding, welding and other methods. The connection ribs can be arranged around the circumference of the second groove, which can further improve the structural strength of the adapter.

[0045] In the above embodiments of the present application, the differences between the various embodiments are mainly described. As long as the different optimized features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, it will not be elaborated here.

[0046] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are only illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all belong to the protection scope of the present application.
