Description

Technical Field

[0001] This application relates to the field of shell structures being mounted on a support surface by means of locking members, and more particularly to a shell assembly and a central control panel. Background Technology

[0002] Smart homes primarily rely on individual product functions and simple interconnections to provide services to users. Existing smart systems utilize a centralized controller, serving as the local interaction center and control hub for all smart home devices. This controller connects all smart appliances, featuring an all-in-one smart design and integrating multiple interaction methods such as voice and touch. It boasts far-field sensitive voice pickup, offering a wealth of voice skills including music, audiobooks, weather, and alarm clock functions. Furthermore, it provides five major concierge services: air quality, energy, health, lighting, and security. A single device controls all smart devices in the house, and based on AI models and algorithms, it provides users with more natural and proactive smart concierge services.

[0003] The current procedure for assembling a centralized controller on a wall typically involves pre-embedding a base shell within the wall and then threading the controller to a pre-set mounting position on the base shell using locking devices. However, the existing assembly environment cannot guarantee proper installation, often resulting in structural dispersion issues during assembly. Due to uneven wall surfaces, protrusions exert a reaction force on the controller, causing the various components to detach or become loosely connected, ultimately affecting the lifespan of the main unit. Utility Model Content

[0004] This application provides a shell assembly and a central control panel to solve the technical problem in the prior art where uneven wall surfaces generate a reaction force on the central controller, which in turn causes the various components of the central controller to become disconnected and the wiring terminals to become loose under the action of this reaction force.

[0005] The shell assembly provided by this utility model includes a first outer shell, a front cover, and a second outer shell. A first position region of the second outer shell is used to provide a first abutting force to prevent the first outer shell from detaching upward from the second outer shell. A second position region of the second outer shell is used to provide a second abutting force to prevent the front cover from detaching upward from the second outer shell. A third position region of the second outer shell is fitted and connected to the front cover. The second outer shell is used to directly bear a reaction force, which tends to exert a pushing effect in the same direction on the second outer shell, the front cover, and the first outer shell. The directions of the first abutting force and the second abutting force are opposite to the direction of the reaction force.

[0006] The first position region of the second outer shell has a first protrusion, the first outer shell has a third protrusion, the first protrusion abuts against the upper part of the third protrusion to form a first abutting surface, and the first abutting force is formed on the first abutting surface.

[0007] The first protrusion has a sliding surface, and the third protrusion slides below the first protrusion via the sliding surface and engages with the first protrusion.

[0008] The second housing has a second protrusion in the second position region, and the front cover has a fourth protrusion. The second protrusion abuts against the upper part of the fourth protrusion to form a second abutting surface, and the second abutting force is formed on the second abutting surface.

[0009] The front cover has a support groove, which is connected above the fourth protrusion. The second protrusion is guided and embedded into the support groove along the inner wall of the support groove.

[0010] The third position region of the second outer shell has a first planar portion, and the front cover has a second planar portion. The second planar portion is located above the first planar portion, and the first planar portion and the second planar portion are fitted together.

[0011] Wherein, the line connecting the center of the first protrusion and the center of the second shell is the first line, and the line connecting the center of the second protrusion and the center of the second shell is the second line, and the first line and the second line are not coplanar.

[0012] The central control panel provided by this utility model includes a high-voltage module and the aforementioned shell assembly. The high-voltage module includes a limiting constraint component and a circuit board with a conductive sheet. The conductive sheet passes through the limiting constraint component and forms an adjustable receiving space with at least a portion of the limiting constraint component for wire harness insertion, thereby clamping and positioning the wire harness circumferentially on one side of the conductive sheet.

[0013] The limiting constraint assembly includes a terminal latch and an adjusting member. The terminal latch is sleeved on the outer periphery of the conductive sheet, and the adjusting member passes through one side of the terminal latch and abuts against the first side of the conductive sheet. A receiving space for wire harness insertion is formed between the second side of the conductive sheet and the inner wall of the terminal latch. The terminal latch is configured to move with the rotation of the adjusting member to adjust the spatial size of the receiving space.

[0014] The second housing includes a terminal receiving cavity, which has a first limiting groove and a second limiting groove. The first limiting groove is used to limit the end structure of the adjusting member so that the adjusting member will not come out of the terminal receiving cavity during rotation. The second limiting groove is used to provide the terminal latch with a moving space along the length direction of the adjusting member itself.

[0015] The terminal buckle is a rotating structure, with one side being a double-layer structure side, including an inner layer side and an outer layer side. The outer layer side has a protruding buckle structure. Next to the double-layer structure side is a single-layer structure side, which has a convex hole. The protruding buckle structure is bent and engages with the convex hole so that the convex hole prevents the outer layer side from coming out.

[0016] The double-layer structure is located near the end structure of the adjusting member, and the convex hole has a diameter that changes from small to large along the direction away from the end structure.

[0017] The tail end of the adjusting member is constructed as a round head structure, which is in clearance fit with the first side of the conductive sheet.

[0018] The technical solutions provided in this application have the following advantages compared with the prior art:

[0019] The shell assembly and central control panel provided in this application embodiment consider the actual installation scenario of the shell assembly. The locking member passes through the second shell and is threadedly tightened to the bottom shell pre-embedded in the wall. Then, the first shell with the front cover is closed and connected to the second shell. One side of the second shell is for direct contact with the wall surface, and the second shell is securely connected to the front cover and the first shell at different positions. When the wall surface is uneven or has protruding impurities, the protruding impurities directly abut against at least a portion of the structure of the second shell, i.e., the protruding impurities generate a blocking force (i.e., reaction force) on the second shell towards the first shell. Because there is a first abutting force between the first position area of ​​the second outer shell and the first outer shell, a second abutting force between the second position area of ​​the second outer shell and the front cover, and a close fit between the third position area of ​​the second outer shell and the front cover; and because the direction of the first abutting force is opposite to the direction of the blocking force, and the direction of the second abutting force is also opposite to the direction of the blocking force, when the blocking force acts on the second outer shell, the second outer shell has a tendency to move towards the first outer shell. Along this tendency, the first outer shell does not obstruct the first position area, and along this tendency, the second outer shell can fit against the front cover and simultaneously have the same tendency to move, preventing the front cover from detaching from the second position area of ​​the second outer shell. Thus, the positions where the second outer shell and the first outer shell, and the second outer shell and the front cover have abutting assembly connection are not affected by external forces from protruding impurities on the wall, ensuring a stable assembly state between the first outer shell, the front cover, and the second outer shell, and preventing any loosening or separation of the first outer shell and the front cover relative to the second outer shell.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0045] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0046] The shell assembly provided by this utility model needs to be installed in a base shell pre-embedded in a wall. Exemplarily, the shell assembly structure sequentially includes a first outer shell and a second outer shell assembled with a front cover. Depending on the application scenario, corresponding circuits, components, and connectors for structural connection or information communication can be installed between the first outer shell and the front cover. Exemplarily, the connector can be a component of a connector, such as pin headers and female headers. The connector can also be a data port or a power supply port, where the data port is used to implement circuit control functions adapted to various scenario requirements, and the power supply port is used to supply power to the circuit. The shell assembly provided by this utility model can be adapted for installation on a wall or ground. It can be understood that the shell assembly of this utility model can be applied to any application scenario where it is installed on a supporting surface via locking components.

[0047] Taking the smart home field as an example, the central controller is an intelligent central control module, which generally has corresponding functions such as power on / off, information interaction, and touch function selection, so as to realize the control function of the whole house smart home.

[0048] A centralized controller typically consists of a housing assembly and circuit modules embedded within it. Centralized controllers are generally wall-mounted. During installation, a base shell is usually pre-installed in the wall, and the centralized controller is then threaded onto a pre-set mounting position on the base shell using locking mechanisms. However, current assembly environments often fail to guarantee proper mounting, frequently resulting in structural dispersion issues during assembly. Due to uneven wall surfaces, the axial pre-tightening force exerted by the locking mechanism between the second and rear housings and the wall can react directly with protrusions on the uneven wall surface, acting on the second housing. Furthermore, the installation gap between the second housing and the first housing (which has a front cover) causes this reaction force to cause the second housing to wobble relative to the front cover, the first housing, or its internal circuitry and control devices or functional modules. This leads to problems such as disconnection between the various components of the centralized controller and loose wiring terminals, ultimately affecting the lifespan of the main unit.

[0049] For ease of describing direction and location, the terms "above" and "below" are used in this embodiment of the invention. Figure 2 The direction shown in the cross-sectional structural diagram is the reference point. In the actual installation process, the upper part here is the front side of the corresponding structure, and the lower part here is the rear side of the corresponding structure.

[0050] To alleviate the aforementioned technical problems, such as Figures 1-11As shown, this embodiment of the disclosure provides a shell assembly 001. Specifically, the shell assembly 001 includes a first outer shell 10, a front cover 20, and a second outer shell 30 assembled from top to bottom. It should be noted that the front cover 20 is connected to the inside of the first outer shell 10. This embodiment of the disclosure does not limit the connection method between the front cover 20 and the first outer shell 10, as long as the front cover 20 and the first outer shell 10 maintain a relatively stable assembly relationship. In this solution, the locking member 60 passes through the second outer shell 30 and locks it between it and the bottom shell 40 pre-embedded in the support surface. For example, a threaded assembly is generally used. Afterwards, the first outer shell 10 with the front cover 20 is closed and connected to the second outer shell 30. For example, the first outer shell 10 and the second outer shell 30 are generally connected by a snap-fit ​​method. To avoid the reaction force F1 from the protruding part of the wall hindering the stable connection between the second outer shell 30 and the first outer shell 10 and the front cover 20, this solution considers that, while ensuring a stable connection between the second outer shell 30 and the first outer shell 10, the structure of the second outer shell 30 is placed on top of both the snap-fit ​​connection areas between the second outer shell 30 and the first outer shell 10 and the snap-fit ​​connection areas between the second outer shell 30 and the front cover 20. Furthermore, there is no obstruction from any structure of the first outer shell 10 or the front cover 20 above the structure of the second outer shell 30 in these two snap-fit ​​connection areas. Simultaneously, the second outer shell 30 can maintain a tight assembly with the first outer shell 10 through the front cover 20. The following section further illustrates this solution through a specific structural description.

[0051] Further reference Figure 2 and Figure 3 In the shell assembly 001 provided by this utility model, the second shell 30 has a first position region. The first position region is used to provide a first abutting force to prevent the first shell 10 from detaching upward from the second shell 30. Here, the first abutting force can be understood as an abutting force generated by an abutting relationship. For example, abutting includes snapping, fastening, etc., to achieve the connection between the second shell 30 and the first shell 10 through the movement or sliding of the respective structural surfaces of the two components. Similarly, it can be understood that the second shell 30 abuts and fastens with the first shell 10 through the first position region, which belongs to the abutting connection method between the second shell 30 and the first shell 10.

[0052] Meanwhile, the second outer shell 30 has a second position region, which provides a second abutting force to prevent the front cover 20 from detaching upwards from the second outer shell 30. This second abutting force can be understood as an abutting force generated by an abutting relationship. For example, abutting includes snapping, fastening, etc., where the connection between the second outer shell 30 and the front cover 20 is achieved through the movement or sliding of the respective structural surfaces of the two components. Similarly, it can be understood that the second outer shell 30 abuts and fastens with the front cover 20 through the second position region, which is a fastening connection method between the second outer shell 30 and the front cover 20.

[0053] Furthermore, the second outer shell 30 has a third position region, which is fitted and connected to the front cover; for example, the second outer shell 30 has a first flat portion 33, and the front cover 20 has a second flat portion 21, the second flat portion 21 being located above the first flat portion 33, and the first flat portion 33 and the second flat portion 21 being fitted together, for reference. Figure 3 The mating plane O3 is used in the design. It should be noted that this mating arrangement ensures that the second outer shell 30 and the front cover 20 form a unified structure. One side of the second outer shell 30 is fitted against the wall, and the other side is fitted against the front cover 20. When the side of the second outer shell 30 that is fitted against the wall is subjected to an external force towards the front cover 20, the second outer shell 30 and the front cover 20 can move as a whole. Simultaneously, due to the mating arrangement, there are no gaps between them, preventing uneven force distribution. Thus, through the mating relationship between the first flat portion 33 of the second outer shell 30 and the second flat portion 21 of the front cover 20, the second outer shell 30 and the front cover 20 can maintain a tight fit, unaffected by external forces.

[0054] In summary, the shell assembly of this utility model ensures that the second outer shell 30, the front cover 20, and the first outer shell 10 are always tightly assembled. For example, when the shell assembly 001 of this utility model is on an uneven wall surface, the third position area of ​​the second outer shell 30 directly bears the reaction force F1 of the protruding position. The reaction force F1 acts directly on the second outer shell 30, tending to push the second outer shell 30, the front cover 20, and the first outer shell 10 in the same direction, wherein the first abutting force and the second abutting force are opposite in direction to the reaction force F1.

[0055] Specifically, under the premise of maintaining a tight assembly between the first outer shell 10, the second outer shell 30, and the front cover 20, the direction of the first abutting force is opposite to the direction of the blocking force (reaction force F1), and the direction of the second abutting force is opposite to the direction of the blocking force (reaction force F1). When the blocking force (reaction force F1) acts on the second outer shell 30, the second outer shell 30 has a tendency to move towards the first outer shell 10. Along the direction of this tendency, the first outer shell 10 does not block the first position area of ​​the second outer shell 30. Along the direction of this tendency, the second outer shell 30 can fit against the front cover 20 and have the same tendency to move in the same direction. The front cover 20 will not come out of the second position area of ​​the second outer shell 30. In this way, the areas where the second outer shell 30 and the first outer shell 10, as well as the areas where the second outer shell 30 and the front cover 20 have abutting assembly connection, are not affected by the external force of the wall protrusions and impurities. This ensures that the first outer shell 10, the front cover 20 and the second outer shell 30 are always in a stable assembly state, and thus prevents the first outer shell 10 and the front cover 20 from becoming loose or separated from the second outer shell 30.

[0056] like Figure 3 As shown, in the abutting and engaging configuration of the second outer shell 30 and the first outer shell 10, to ensure that there is no obstruction from the first outer shell 10 above the second outer shell 30 within the engagement area, the second outer shell 30 has a first protrusion 31 in its first position region, and the first outer shell 10 has a third protrusion 11. The first protrusion 31 abuts against the third protrusion 11, forming a first abutting surface O1. Figure 3 The first contact force is formed on the first contact surface O1 (where O1 is located). This ensures that the reaction force F1 generated by the protruding part of the wall (…) is maintained. Figure 3 As shown in F1, the second outer shell 30 will not act on the first abutting surface O1, and thus will not affect the abutting engagement state of the second outer shell 30 and the first outer shell 10 at the first abutting surface O1.

[0057] In the actual assembly scenario of the first outer shell 10 relative to the second outer shell 30, the first outer shell 10 needs to be assembled after the second outer shell 30 is assembled to the wall. In the actual installation process, the first outer shell 10 and the second outer shell 30 often have loose fastening or need to be fastened multiple times.

[0058] To alleviate this problem, such as Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, in the shell assembly 001 provided by this solution, the first protrusion 31 has a sliding surface 311. The sliding surface 311 is used to guide the third protrusion 11 to slide below the first protrusion 31, so that the third protrusion 11 engages with the first protrusion 31. For example, the sliding surface 311 can be an inclined surface or a curved surface. Correspondingly, the area of ​​the third protrusion 11 that is used to slide in cooperation with the sliding surface 311 can also be an inclined surface or a curved surface. In this way, when the first shell 10 is assembled and fastened toward the second shell 30, the third protrusion 11 of the first shell 10 slides through the sliding surface 311 and slides below the first protrusion 31 of the second shell 30. This assembly method can save the time of aligning and assembling the first shell 10 with the second shell 30, and further achieve high efficiency in the engagement assembly process of the first shell 10 with the second shell 30.

[0059] In this embodiment, the shape and position of the protruding structures of the first protrusion 31 of the second outer shell 30 and the third protrusion 11 of the first outer shell 10 are not limited, as long as the engaging relationship between the second outer shell 30 and the first outer shell 10 at the first abutting surface O1 is ensured, so that the second outer shell 30 and the first outer shell 10 will not separate at that position. For example, the first protrusion 31 can be any of the following: a block structure, a column structure, or a three-dimensional structure of any shape that protrudes from its own outer wall, inner wall, or top wall. Similarly, the third protrusion 11 can also be any of the following: a block structure, a column structure, or a three-dimensional structure of any shape that protrudes from its own inner wall, outer wall, or bottom wall.

[0060] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in the engagement scheme between the second outer shell 30 and the front cover 20, to ensure that there is no obstruction of the second outer shell 30 by the front cover 20 above the engagement position area, the second outer shell 30 has a second protrusion 32 in its second position area, and the front cover 20 has a fourth protrusion 22. The second protrusion 32 abuts against the fourth protrusion 22 to form a second abutting surface O2, and a second abutting force is formed on the second abutting surface O2. This ensures that the reaction force F1 generated by the wall protrusion will not act on the second abutting surface O2 via the second outer shell 30, thus not affecting the engagement state of the second outer shell 30 and the front cover 20 at the second abutting surface O2.

[0061] In this embodiment, the shape and position of the protruding structures of the second protrusion 32 of the second outer shell 30 and the fourth protrusion 22 of the front cover 20 are not limited, as long as the snap-fit ​​relationship between the second outer shell 30 and the front cover 20 on the second abutment surface O2 is ensured, so that the second outer shell 30 and the front cover 20 will not separate at that position. For example, the second protrusion 32 can be any of the following: a block structure, a column structure, or a three-dimensional structure of any shape that protrudes from the inner wall (inner sidewall), top wall, or bottom wall of the second outer shell 30. Correspondingly, the fourth protrusion 22 can also be any of the following: a block structure, a column structure, or a three-dimensional structure of any shape that protrudes from the outer wall, inner wall, or bottom wall of the second outer shell 30. Taking the second protrusion 32 protruding from the inner sidewall of the second outer shell 30 as an example, correspondingly, the fourth protrusion 22 protrudes from the outer sidewall of the front cover 20, and the bearing groove 23 is formed on the outer sidewall of the front cover 20.

[0062] In this embodiment, the front cover 20 is generally installed close to the second outer shell 30, and the front cover 20 protrudes from the first outer shell 10. This can be understood as the front cover 20 being located between the first outer shell 10 and the second outer shell 30. In actual assembly scenarios, after the second outer shell 30 is assembled to the wall, the first outer shell 10 with the front cover 20 is then assembled to the second outer shell 30. During actual installation, problems frequently arise where the fasteners between the first outer shell 10 and the second outer shell 30 become loose or require multiple fastening operations.

[0063] To alleviate this problem, such as Figure 3 , Figure 4 and Figure 6 As shown, in the shell assembly 001 provided by this solution, the front cover 20 has a support groove 23, which is connected above the fourth protrusion 22. The second protrusion 32 is guided and embedded into the support groove 23 along the inner wall of the support groove 23. For example, the support groove 23 can be a curved groove or a linear groove. Correspondingly, the area of ​​the fourth protrusion 22 that is used to slide with the support groove 23 can also be a curved surface or an inclined surface. In this way, the front cover 20 slides downward along the surface of the second protrusion 32 through the fourth protrusion 22, and the second protrusion 32 can be fitted into the support groove 23, and / or the second protrusion 32 abuts against at least a part of the structure of the fourth protrusion 22. The second protrusion 32 of the second shell 30 plays a guiding and locking role, which can achieve high efficiency in the first shell 10 and the second shell 30 locking assembly process.

[0064] In this embodiment, along the assembly direction of the first outer shell 10 relative to the second outer shell 30, the second protrusion 32 of the second outer shell 30 has a guide surface, which can be constructed as an inclined surface or a curved surface. In this way, the second outer shell 30 can smoothly slide along the inner wall of the bearing groove 23 of the front cover 20 via the guide surface and abut against the top of the fourth protrusion 22 of the front cover 20, thereby facilitating and improving the engagement efficiency of the front cover 20 relative to the second outer shell 30.

[0065] In the configuration where the third position region of the second outer shell 30 is fitted and connected to the front cover 20, the third position region of the second outer shell 30 has a first flat portion 33, and the front cover 20 has a second flat portion 21. The second flat portion 21 is located above the first flat portion 33, and the first flat portion 33 and the second flat portion 21 are fitted together. This ensures that the second outer shell 30 drives the front cover 20 to move upward in the same direction. For example, there may be a pre-adhesive force between the first flat portion 33 and the second flat portion 21, which can be understood as a pre-tightening force between the two planes. This pre-tightening force is used to balance the first and second abutment forces in the fastened state.

[0066] In actual assembly, if the first protrusion 31 and the second protrusion 32 are symmetrically positioned relative to the center of the second outer shell 30, an unstable assembly may occur between the first outer shell 10, the front cover 20, and the second outer shell 30. This is because when the first protrusion 31 and the second protrusion 32 are symmetrically positioned relative to the center of the second outer shell 30, the stresses borne on the first contact surface O1 and the second contact surface O2 will be coplanar. In this case, the stress borne by the second outer shell 30 as a whole will be superimposed, which will be detrimental to the overall assembly stability of the shell assembly 001.

[0067] To alleviate the aforementioned problems, a first line is drawn connecting the center of the first protrusion 31 and the center of the second outer shell 30, and a second line is drawn connecting the center of the second protrusion 32 and the center of the second outer shell 30. The first and second lines are designed to be non-coplanar. This ensures that the arrangement of the first and second protrusions 31 and 32 relative to the second outer shell 30 is asymmetrical, thereby ensuring that the forces exerted by the first and second protrusions 31 and 32 on the second outer shell 30 are more dispersed. Alternatively, a portion of the first contact force of the first protrusion 31 can offset a portion of the second contact force of the second protrusion 32. This dissipates some unnecessary forces within the structure of the second outer shell 30 itself, preventing them from acting between the second outer shell 30 and the first outer shell 10, or between the second outer shell 30 and the front cover 20, thus improving the service life of the overall shell assembly 001.

[0068] Considering the quick-guided assembly of the front cover 20 relative to the first outer shell 10, such as Figure 7 As shown, embedded insert structures 24 are provided at the four corners of the front cover 20. The embedded insert structure 24 can be understood as guide inserts. Correspondingly, the first outer shell 10 has guide mounting grooves. Based on the design of the embedded insert structure 24, the front cover 20 is fixed to the first outer shell 10 by screws, which effectively improves the firmness of the front cover 20 and prevents the front cover 20 from loosening.

[0069] The use of the shell assembly 001 described above can effectively improve the locking and snapping stability of the first shell 10, the front cover 20 and the second shell 30 bracket, and can also prevent the problem of warping and easy popping open caused by uneven wall surface, thus ensuring the safety of the high-voltage module.

[0070] The housing assembly 001 provided by this utility model, considering its application in the smart home field, also includes a touch panel, an anti-steam silicone pad, a high-voltage module 50, and a partition 70. The touch panel is bonded to one side of the first housing 10 via an adhesive drip tray. A front cover 20 is mounted on the other side of the first housing 10. An anti-steam silicone pad is placed between the first housing 10 and the front cover 20. Generally, the front cover 20 houses a functional circuit board 53 and pin headers connected to the functional circuit board 53. The anti-steam silicone pad prevents steam from damaging the components inside the front cover 20. Furthermore, the high-voltage module 50 is generally installed in the second housing 30. The high-voltage module 50 has a built-in circuit board 53, typically connected to a connector. Thus, the high-voltage module 50 connects to the pin headers of the front cover 20 via the connector, including both physical snap-fit ​​and electrical connection. The high-voltage module 50 is connected to electrical wires extending from the wall via a conductive sheet 52, thereby providing power to the high-voltage module 50. A partition 70 is positioned between the high-voltage module 50 and the front cover 20 to prevent electric shock hazards during user operation. Considering the electrical connection and physical connection between the socket of the high-voltage module 50 and the pins of the front cover 20, when the housing assembly 001 is in the snap-fit ​​state, the front cover 20 is spaced apart from the circuit board 53 of the high-voltage module 50 via the partition 70. Because of the gap between the partition 70, the socket, and the circuit board 53, moisture from inside the wall can flow through these gaps to the point where the pins connect to the socket, potentially causing a short circuit and affecting the touch control or circuit functionality of the central control panel 002. Furthermore, it should be noted that in existing systems, the conductive sheet 52 requires screws to secure the wire to one side of the conductive sheet 52 at the connection point, frequently resulting in the screws damaging the conductive sheet 52.

[0071] To alleviate the above problems, further reference Figures 1-11 The central control panel 002 provided by this utility model includes the aforementioned shell assembly 001. The high-voltage module 50 includes a limiting constraint assembly 51 and a circuit board 53 with a conductive sheet 52. The conductive sheet 52 passes through the limiting constraint assembly 51 and forms, at least partially, an adjustable receiving space 54 for wire harness insertion, used to clamp and position the wire harness circumferentially on one side of the conductive sheet 52. It should be noted that the limiting constraint assembly 51 is mainly used to clamp and limit the wires extending from the wall relative to the conductive sheet 52. Using the limiting constraint assembly 51 can prevent screws from directly pressing against the wire harness (wire) and the conductive sheet 52. The following describes this solution through its specific structure.

[0072] In this embodiment, such as Figure 9 and Figure 10As shown, the limiting constraint assembly 51 includes a terminal latch 511 and an adjusting member 512. The terminal latch 511 is sleeved on the outer periphery of the conductive sheet 52, and the adjusting member 512 passes through one side of the terminal latch 511 and has a gap fit with the first side of the conductive sheet 52. This creates a gap between the adjusting member 512 and the conductive sheet 52, preventing direct pressure on the wire harness or the conductive sheet 52 and thus avoiding damage. Furthermore, a receiving space 54 for wire harness insertion is formed between the second side of the conductive sheet 52 and the inner wall of the terminal latch 511; this receiving space 54 is the aforementioned adjustable receiving space 54. By moving the terminal latch 511 in accordance with the rotation of the adjusting member 512, the spatial dimensions of the receiving space 54 can be adjusted during the rotation of the adjusting member 512.

[0073] For example, the conductive sheet 52 is a sheet structure that is plugged into or fixedly connected to the circuit board 53 of the high-voltage module 50. The first side of the conductive sheet 52 has a recessed area and the second side of the conductive sheet 52 has a raised area. The recessed area is used for clearance fitting with the tail end of the adjusting member 512, and the raised area is used for electrical connection with the wire harness.

[0074] Considering the actual assembly scenario of the aforementioned limit constraint component 51, further refer to... Figure 9 The second housing 30 is designed with a terminal receiving cavity 34, wherein the terminal receiving cavity 34 has a first limiting groove 341 and a second limiting groove 342. The first limiting groove 341 is used to limit the end structure 5121 of the adjusting member 512 so that the adjusting member 512 will not come out of the terminal receiving cavity 34 during rotation. The second limiting groove 342 is used to provide the terminal latch 511 with a moving space along the length direction of the adjusting member 512 itself.

[0075] In this embodiment, the adjusting member 512 is a bolt or screw-like structure, with its tail end used for clearance engagement with the first side of the conductive sheet 52. Its end structure 5121 has a raised shoulder structure, which facilitates the limiting of the adjusting member 512. Specifically, the raised shoulder structure is installed in the first limiting groove 341, ensuring that the adjusting member 512 does not detach from the terminal receiving cavity 34, i.e., the adjusting member 512 does not detach from the second outer shell 30 having the terminal receiving cavity 34. Furthermore, the second limiting groove 342 provides sufficient space for the terminal latch 511 to insert the wire harness. For example, the second limiting groove 342 adopts a closed sleeve structure, allowing the terminal latch 511, conductive sheet 52, and adjusting member 512 in the limiting constraint assembly 51 to be fitted into the terminal receiving cavity 34 along the opening on one side of the second limiting groove 342.

[0076] For example, one, two, or more conductive plates 52 can be inserted into the circuit board 53 of the high-voltage module 50 according to actual circuit requirements. Each conductive plate 52 is used to make an electrical connection with the wires extending from the wall. Correspondingly, one, two, or more limiting constraint components 51 of this utility model can also be adapted to ensure that each wire can be tightly connected to the corresponding conductive plate 52, and that stress concentration at the point will not cause damage to the wires or conductive plates 52. The following further illustrates this solution through a specific structure.

[0077] In this embodiment, the central control panel 002 with the limit constraint component 51 is applied as described above. In actual application, the terminal buckle 511 in the limit constraint component 51 will be inserted from one side of the terminal receiving cavity 34 so that the shoulder structure of the adjusting member 512 is inserted into the first limiting groove 341 of the terminal receiving cavity 34. At the same time, the terminal buckle 511 can be embedded in the second limiting groove 342 of the terminal receiving cavity 34.

[0078] Taking the adjusting component 512 as a screw as an example, the screw includes a screw head and a stud. In this solution, the end structure 5121 of the screw includes a screw head and a shoulder structure. The screw head can be an internal hexagon screw head. The shoulder structure is a protruding structure that protrudes from the outer wall of the stud. That is, the shoulder structure is a protruding structure that extends in the opposite direction to the radial direction of the stud. The outer wall of the shoulder structure needs to protrude from the outer wall of the screw head. Correspondingly, the outer wall of the terminal receiving cavity 34 will not block the screw head from being turned. That is, a safety gap is left between the terminal receiving cavity 34 and the screw head. Furthermore, the terminal latch 511 is housed within the second limiting groove 342. Since the limiting constraint component 51 in this solution uses the screw's turning rotation, and the terminal latch 511 and the adjusting component 512 are connected by a threaded assembly, the turning rotation of the adjusting component 512 can cause the terminal latch 511 to move along the length direction of the screw stud. Specifically, this includes the terminal latch 511 moving towards the direction closer to the screw head and the terminal latch 511 moving towards the direction away from the screw head. During the screw turning rotation and the movement of the terminal latch 511, under the limiting action of the first limiting groove 341 and the shoulder structure, it can be ensured that the screw does not move and the terminal latch 511 moves. Furthermore, since the terminal clip 511 adopts a rotating structure, the insertion of the conductive sheet 52 into the terminal clip 511 can create two spaces during the movement of the terminal clip 511. One space is the first space between the protruding area of ​​the conductive sheet 52 and the first inner wall of the terminal clip 511 for clamping the wire harness. The other space is the second space between the recessed area of ​​the conductive sheet 52 and the second inner wall of the terminal clip 511. The second space also includes a stud that rotates but does not move. Since the tail end of the stud and the recessed area of ​​the conductive sheet 52 always maintain a fixed clearance fit (in conjunction with the first limiting groove 341), the shrinkage of the first space corresponds to the enlargement of the second space, and the enlargement of the first space corresponds to the shrinkage of the second space. That is, the first space is the aforementioned adjustable accommodating space 54 for wire harness insertion. The internal space of the rotating body of the terminal clip 511 cannot be changed during application.

[0079] The existing terminal clip 511 has a sleeve-shaped structure formed by sheet metal bending. It can be understood that the terminal clip 511 is a rotating structure with a U-shaped cross-section formed by bending a sheet metal piece, including rounded corners and a double-layered structure on one side. However, the limiting constraint component 51 of this invention involves the tightening and rotation of a screw during application. Since the screw's threaded connection with the terminal clip 511 is located within this double-layered structure, the screw stud passes through both the outer and inner layers during tightening. During the threaded connection with the outer layer, the screw's axial preload F2 acts on the outer layer, generating a force opposite to the inner layer. This opposing force is opposite to the direction of the screw's axial preload F2, thus causing a force difference between the inner and outer layers. The problem is that the inner structure side moves in opposite directions relative to each other. Since there is no structural support on the side away from the outer structure side, the inner structure side will move away from the side where the stud is located. Due to the molding process characteristics of the terminal clip 511, the surfaces formed by each bend are connected in an extended manner, and there is an extension stress between the surfaces. When the aforementioned inner structure side is subjected to this opposite force, it will connect with the other surface structures and move away from the conductive sheet 52, thereby causing the terminal clip 511 to explode in the second limiting space.

[0080] To alleviate the aforementioned problems, the terminal clip 511 in this solution, while employing sheet metal bending technology, adjusts its structural composition by embedding a portion of the outer layer 51111 into the adjacent structural side. This avoids the formation of an opening between the outer layer 51111 and the inner layer of the double-layer structure, thereby preventing the opening from being blown open under the action of opposing forces. The solution is further illustrated below with a specific structural description.

[0081] In this embodiment, such as Figure 10 and Figure 11As shown, the terminal buckle 511 is constructed as a rotating structure, specifically a hollow cylindrical structure. For example, the terminal buckle 511 can be any of square, circular, trapezoidal, or irregular shapes. Taking the terminal buckle 511 as a square barrel structure as an example, the terminal buckle 511 is made by bending and riveting processes. During the bending process, one side of the terminal buckle 511 is constructed as a double-layer structure side 5111, including an inner layer side and an outer layer side 51111. The outer layer side 51111 is stacked on the outside of the inner layer side. At the same time, the outer layer side 51111 has a protruding buckle structure 51112. The protruding buckle structure 51112 can be understood as having a smaller size on the side closer to its main body surface and a larger size on the side farther from its main body surface. It should be noted that a single-layer structure side 5112 is provided next to the double-layer structure side 5111. The single-layer structure side 5112 has a convex hole 51121. The convex buckle structure 51112 is bent and engages with the convex hole 51121 to prevent the outer layer side 51111 from coming out. Using a terminal clip 511 structure can effectively prevent terminal cracking during installation, improve product lifespan, and reduce product maintenance costs.

[0082] Considering that the convex buckle structure 51112 and the convex hole 51121 can be engaged and form an abutment surface to resist the aforementioned opposing forces, the long side of the convex buckle structure 51112 abuts against the inner wall of the convex hole 51121, thereby forming a mutually abutting engagement relationship between the two side structures. At the same time, the rotating structure of the terminal latch 511 will not be damaged under external force, that is, the terminal latch 511 will not cause the problem of bursting open.

[0083] Considering that the convex buckle structure 51112 can accurately rivet into the convex hole 51121, the convex hole 51121 is defined as follows: along the direction away from the end structure 5121, the diameter of the convex hole 51121 changes from small to large. Correspondingly, the long side of the convex buckle structure 51112 on the outer side 51111 is used to abut against the inner wall of the convex hole 51121, forming a contact force on this contact surface. This force can resist the axial preload force F2 of the screw, ensuring that the convex buckle structure 51112 and the convex hole 51121 will not separate from each other. Furthermore, this ensures that the terminal clip 511 will not burst open under the axial preload force F2 of the screw.

[0084] Considering the actual scenario of the clearance fit between the tail end of the adjusting member 512 and the conductive sheet 52, the tail end of the adjusting member 512 (screw or stud) is used to assemble with the recessed area of ​​the conductive sheet 52 with clearance fit. The application of the adjusting member 512 in the limiting constraint assembly 51 is to rotate. Further considering the installation and application stability of the adjusting member 512 in the limiting constraint assembly 51 and the terminal receiving cavity 34, the clearance between the tail end of the adjusting member 512 and the recessed area of ​​the conductive sheet 52 is adjusted to a uniform clearance. This can also prevent the screw from disengaging from the corresponding support surface on the terminal receiving cavity 34 and causing shaking during the rotation of the adjusting member 512.

[0085] In this embodiment, further reference is made to Figure 9 The tail end of the adjusting member 512 can be constructed as a round head structure, which is clearance-fitted with the first side of the conductive sheet 52. In this way, during the screwing and rotation of the adjusting member 512, the round head structure at its tail end, due to its rotating body construction, can always maintain a clearance fit relative to the first side of the conductive sheet 52, further preventing the adjusting member 512 (screw or bolt) from damaging the conductive sheet 52 during installation. For example, the side of the tail end of the adjusting member 512 near the recessed area of ​​the conductive sheet 52 can be constructed as a curved surface. The gap between this curved surface and the recessed area on the conductive sheet 52 can be equal or unequal. When the gap between the curved surface at the tail end of the adjusting member 512 and the recessed area on the conductive sheet 52 is unequal, it is sufficient to ensure that the curved surface within the preset radius area at the center of the stud has an equal gap with the curved surface at the tail end of the adjusting member 512. This solution does not limit the range of the preset radius area; it depends on the requirements of the actual installation scenario.

[0086] By constructing the tail end of the adjusting member 512 as a round head structure, large dimensional changes between the stud and the tail end of the adjusting member 512 can be avoided, thus preventing large chamfers or large taper angles. This is because the side of the terminal latch 511 that is threadedly connected to the stud is close to the side of the recessed area of ​​the conductive sheet 52, and the recessed area of ​​the conductive sheet 52 is used for clearance fit with the tail end of the stud. In this way, the terminal latch 511 will be extremely close to the conductive sheet 52 in a certain state. Furthermore, the terminal latch 511 has a certain thickness. Therefore, in order to avoid wobbling between the conductive sheet 52, the terminal latch 511, the stud, and the tail end of the adjusting member 512, the radial dimension between the stud and the tail end of the adjusting member 512 should be changed as slowly as possible, thus preventing wobbling connection between the terminal latch 511 and the stud.

[0087] In summary, the design of the shell assembly 001 and central control panel 002 of this utility model can prevent the disengagement of the various components of the shell assembly 001 and the loosening of the wiring terminals caused by uneven wall surfaces. At the same time, the central control panel 002 with the high-voltage module 50 can also constrain the wiring harness connected to the wall, preventing the adjusting part 512 (screw or stud) from directly pressing and damaging the wiring harness and conductive sheet 52. Furthermore, with the application of the new terminal clip 511 structure, the terminal clip 511 will not explode in the second limiting groove 342 of the terminal receiving cavity 34 inside the second outer shell 30, thereby preventing collision damage to the terminal receiving cavity 34 and the second outer shell 30, thus improving the service life of the shell assembly 001 and the central control panel 002 as a whole.
