[0046] At present, with the development of economy, the popularity of smart home is getting higher and higher. The smart panel of the central control system of smart home is the key to realize the intelligence of home. At present, the installation method of the mainstream smart control panel in the market is to embed it in the wall of the home. Its structure is divided into the rear shell assembly and the front shell assembly. The rear shell assembly is composed of the rear shell and the power supply, and the front shell assembly is composed of the front shell, PCB and touch panel. Generally, the rear shell assembly is embedded in the wall. Since the front shell assembly needs to bear the functions of display and voice, it needs to be exposed outside the wall. The thickness of the front shell assembly exposed on the wall is too thick. The current mainstream thickness is about 10mm, which affects the user experience. The front shell assembly of the existing smart panel is generally fixed with the rear shell assembly embedded in the wall by screws and buckles. The screw and buckle structure squeezes the overall thickness of the front shell assembly, which not only makes the assembly operation difficult, but also increases the thickness of the front shell assembly.

[0047] The related technology provides a snap-on installation structure, in which the snap-on mounting structure extends upward from the bottom of the annular protrusion and is a lying L-shaped notch. The clamping column needs to be inserted into the snap-on mounting first and then rotated to be snapped into the snap-on mounting. The positional accuracy of the snap-on mounting and the clamping column is high, which increases the difficulty of operation.

[0048] Combination Figure 1-9 As shown, the embodiment of the present disclosure provides a control panel 40, including a front shell component 10, a rear shell component 20 and a rotating connection component 30, wherein the rear shell component 20 is used to be arranged in the installation base surface; the rotating connection component 30 includes a snap-fit ​​end 31 and a fixed end 32, wherein the snap-fit ​​end 31 is arranged on the front shell component 10, and the fixed end 32 is arranged on the rear shell component 20; wherein, the snap-fit ​​end 31 includes an elastic snap-fit ​​structure 311, and the fixed end 32 includes a snap-fit ​​matching structure 321, and the snap-fit ​​end 31 is rotated to make the elastic snap-fit ​​structure 311 abut against and snap-fit ​​with the snap-fit ​​matching structure 321, so that the front shell component 10 and the rear shell component 20 can be fixedly connected.

[0049] The rotational assembly method of the front housing assembly 10, the rear housing assembly 20 and the rotational connection assembly 30 is as follows: Figure 8 The control panel 40 is mounted on the wall 50 in the following manner: Fig. 9 shown.

[0050] The control panel 40 provided by the embodiment of the present disclosure is adopted, and the rear shell component 20 of the control panel 40 is arranged in an installation base surface such as a wall 50, and the front shell component 10 and the rear shell component 20 are fixedly connected by a rotating connection component 30. The clamping end 31 provided on the front shell component 10 includes an elastic clamping structure 311, and the fixed end 32 provided on the rear shell component 20 includes a clamping matching structure 321. The elastic clamping structure 311 and the clamping matching structure 321 can be clamped against each other only by rotating the clamping end 31, which is simple to operate and improves the installation efficiency. Moreover, the elastic clamping can achieve interference after clamping, which improves the stability of the clamping fixation. At the same time, the front shell component 10 and the rear shell component 20 are assembled by rotation, which is convenient for assembly and disassembly. The fixed connection is fixed by rotating clamping, which reduces the use of screws and avoids the problem of increased thickness caused by screw fixing.

[0051] Optionally, combined Figure 2-5 As shown, the elastic snap-fit ​​structure 311 includes a body 312 and an elastic wall 313, the body 312 is connected to the front shell assembly 10; the elastic wall 313 is arranged on the body 312 and protrudes toward the front shell assembly 10, and there is a gap between the elastic wall 313 and the front shell assembly 10; Figure 2-3 and Figure 6-7 As shown, the snap-fitting structure 321 includes a snap-fitting wall 322, which extends along a first direction and can be snapped into the gap and abutted against the protrusion to cause the elastic wall 313 to undergo elastic deformation, and the elastic snap-fitting structure 311 is snap-fitted with the snap-fitting structure 321; wherein the first direction is a direction perpendicular to the protruding direction of the elastic wall 313.

[0052] The body 312 of the elastic snap-fit ​​structure 311 is connected to the front shell assembly 10, and the elastic wall 313 provided on the body 312 is convexly arranged toward the front shell assembly 10, so that the elastic wall 313 can be elastically deformed in the convex direction, so that under the action of external force, it can elastically move toward the front shell assembly 10 or away from the front shell assembly 10 along the convex direction. The clamping wall 322 extends in a direction perpendicular to the convex direction of the elastic wall 313, and can form a contact surface with the elastic wall 313. There is a gap between the elastic wall 313 and the front shell assembly 10. After the clamping wall 322 is clamped into the gap, it can contact and resist the convexity, so that the convexity is elastically deformed, and an interference connection is achieved. Through the interference connection, the elastic wall 313 and the clamping wall 322 can be tightly combined together, and the connection is stable and reliable.

[0053] Optionally, combined Figure 3-5 As shown, the front shell assembly 10 includes a touch panel 11 and a front shell 12; the front shell 12 is arranged on the back of the touch panel 11 and is connected to the touch panel 11, and the locking end 31 is arranged on the side of the front shell 12 away from the touch panel 11; wherein, the front shell 12 is provided with a stop portion 121, which is arranged on the other side protruding relative to the elastic wall 313 to limit the elastic movement range of the elastic wall 313.

[0054] The front shell 12 is disposed on the back of the touch panel 11 and is fixedly connected to the touch panel 11. The touch panel 11 can be directly fixedly connected to the front shell 12 by a glue dispensing process. The clamping end 31 is disposed on the side of the front shell 12 away from the touch panel 11, and the clamping end 31 cooperates with the fixed end 32, so that the rear shell assembly 20 and the front shell 12 can be connected by rotation.

[0055] The stopper 121 of the front shell 12 is arranged on the other side of the protrusion relative to the elastic wall 313, and forms an elastic space with the elastic wall 313. After the clamping wall 322 is clamped into the gap and contacts with the protrusion, the elastic wall 313 undergoes elastic deformation and moves toward the stopper 121. The stopper 121 blocks the elastic wall 313, limits the elastic movement range of the protrusion of the elastic wall 313, and can prevent the elastic wall 313 from moving excessively. At the same time, the stopper 121 also limits the elastic clamping structure 311, limiting the elastic clamping structure 311 to the front shell 12.

[0056] Combination Figure 4-5 As shown, the stopper 121 provided in the embodiment of the present disclosure is a stopper block. The middle part of the elastic wall 313 is convex, and the stopper block is arranged on the other side of the convex part of the elastic wall 313, and abuts against the two ends of the elastic wall 313. An elastic space is formed between the convex part and the stopper block, which is suitable for the elastic movement of the elastic wall 313. It can be understood that the stopper 121 can also be other stopper structures such as a stopper sheet.

[0057] Optionally, combined Figure 4-5 As shown, the front shell 12 is further provided with a positioning portion 124 , and the body 312 is provided with a positioning matching portion 314 . The positioning portion 124 cooperates with the positioning matching portion 314 to position the elastic snap-fit ​​structure 311 on the front shell 12 .

[0058] When the clamping end 31 is fixed to the front shell assembly 10, the positioning portion 124 can be matched with the positioning matching portion 314 to position the elastic clamping structure 311 on the front shell 12, so that the position of the clamping end 31 can be more accurate. The elastic clamping structure 311 is also provided with a fixing hole, and the elastic clamping structure 311 is fixed to the front shell 12 by screws passing through the fixing hole.

[0059] Combination Figure 4-5 As shown, the positioning portion 124 provided in the embodiment of the present disclosure is a card block, and the positioning matching portion 314 is a card slot, which is card-connected to the card block, so that the elastic card structure 311 is positioned on the front shell 12, and the screw holes provided on the elastic card structure 311 and the front shell 12 can be accurately aligned to achieve accurate fixation of the screws.

[0060] Optionally, combined Figure 4As shown, the front shell 12 has a first opening 122 extending through it along the thickness direction toward the touch panel 11 . The front shell assembly 10 further includes a circuit board 13 , which is disposed on the other end surface of the front shell 12 and located at the first opening 122 .

[0061] In the disclosed embodiment, the circuit board 13 is directly fixed to the front shell 12, and the circuit board 13 is arranged at the first opening 122 on the other end surface of the front shell 12.

At the same time, the first opening 122 also helps the electronic components to dissipate heat better and keep the temperature of the electronic components stable.

[0062] Optionally, combined Figure 4-5 As shown, the front shell 12 is provided with a plurality of limiting structures 123, and the plurality of limiting structures 123 are distributed along the circumference of the first opening 122 on the other end surface of the front shell 12, and the plurality of limiting structures 123 define a placement space, and the circuit board 13 is located in the placement space to limit the position of the circuit board 13 at the first opening 122 of the front shell 12.

[0063] According to the position of the first opening 122 and the size and shape of the circuit board 13, a plurality of limiting structures 123 are arranged along the circumference of the first opening 122 to define a placement space for the circuit board 13 and to limit the circuit board 13 at the first opening 122 of the front housing 12. The plurality of limiting structures 123 may be evenly distributed along the circumference of the first opening 122. The plurality of limiting structures 123 may also be unevenly distributed and arranged at specific positions according to the size and shape of the circuit board 13.
