However, the existing assembly environment cannot guarantee that the centralized controller will have structural dispersion problems during the assembly process. That is, due to the uneven wall surface, the protrusions on the wall surface will generate a reaction force on the centralized controller, which will cause the components of the centralized controller to be disconnected and the wiring terminals to be loose under the action of the reaction force, thereby affecting the service life of the host. Summary of the invention

At the same time, the second shell is firmly connected to the front cover and the first shell at different positions. When the wall surface is uneven and there are protruding impurities on the surface, the protruding impurities directly abut at least part of the structure of the second shell, that is, the protruding impurities generate a blocking force (i.e., a reaction force) on the second shell in the direction of the first shell. Since there is a first abutting force between the first position area of ​​the second shell and the first shell, there is a second abutting force between the second position area of ​​the second shell and the front cover, and the third position area of ​​the second shell and the front cover are fitted together; and since 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 shell, the second shell has a movement trend toward the first shell, and along the direction of the movement trend, the first shell does not produce a blocking effect on the first position area, and along the direction of the movement trend, the second shell can fit the front cover and have a movement trend in the same direction, and the front cover will not fall out of the second position area of ​​the second shell.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0045] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may 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 herein are interpreted accordingly.

[0046] The shell assembly provided by the present invention needs to be installed in a bottom shell pre-buried in the wall. Exemplarily, the structure of the shell assembly includes a first shell and a second shell assembled with a front cover in sequence, and, according to the requirements of the application scenario of the shell assembly, corresponding circuits, various components and connector devices for structural connection or information communication can be installed between the first shell and the front cover. Exemplarily, the connector device can be a component structure of a connector, such as a pin header and a female header. The connector device can also be a data port or a power supply port, wherein the data port is used to realize a circuit control function adapted to the requirements of each scenario, and the power supply port is used to realize the power supply to the circuit. The shell assembly provided by the present invention can be adapted to be installed on a wall or the ground. It can be understood that the shell assembly of the present invention can be applied to any application scenario in which it is installed on a supporting surface through a locking member.

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

[0048] The centralized controller generally includes a shell component and a circuit module embedded in the shell component, and the centralized controller generally needs to be installed on the wall. During the installation process, a bottom shell is generally pre-embedded in the wall, and then the centralized controller is threadedly assembled with the preset installation position on the bottom shell through the locking member. However, the existing assembly environment cannot guarantee that the centralized controller often has structural dispersion problems during the assembly process, that is, due to the uneven wall surface, the locking member passes through the axial preload between the second shell and the rear shell and the wall, and the reaction force of the axial preload will directly act on the second shell through the protruding impurities on the uneven wall surface. Since there is an installation gap between the second shell and the first shell equipped with the front cover, the reaction force will cause the second shell to shake relative to the front cover and the first shell or the circuit control device or functional module inside it, which will cause the components of the centralized controller to be disconnected and the wiring terminals to be loose, thereby affecting the service life of the host.

[0049] In order to facilitate the description of directions and positions, the upper and lower parts in the embodiments of the present invention are referred to as Figure 2 The direction of the cross-sectional structure schematic diagram is taken as the standard. During the actual installation process, the upper side here is the front side of the corresponding structure, and the lower side here is the rear side of the corresponding structure.

[0050] In order to alleviate the above technical problems, such as Figure 1-Figure 11As shown, the embodiment of the present disclosure provides a shell assembly 001. Specifically, the shell assembly 001 includes a first shell 10, a front cover 20 and a second shell 30 assembled from top to bottom. It should be pointed out that the front cover 20 is connected to the inner side of the first shell 10. The embodiment of the present disclosure does not limit the connection method between the front cover 20 and the first shell 10, as long as it is ensured that the front cover 20 and the first shell 10 maintain a relatively stable assembly relationship. In this solution, the locking member 60 passes through the second shell 30 and the bottom shell 40 embedded in the support surface for locking assembly. Exemplarily, threaded assembly is generally adopted. Afterwards, the first shell 10 equipped with the front cover 20 is covered and connected to the second shell 30. Exemplarily, the first shell 10 and the second shell 30 are generally connected in a snap-fit ​​manner. In order to avoid the problem that the reaction force F1 at the raised position of the wall blocks the stable connection between the second housing 30 and the first housing 10 and the front cover 20, the present solution considers setting the structure of the second housing 30 on the top of the snap-fit ​​connection position area between the second housing 30 and the first housing 10 and the snap-fit ​​connection position area between the second housing 30 and the front cover 20, and there is no shielding of any structure of the first housing 10 and the front cover 20 above the structure of the second housing 30 in the two snap-fit ​​connection position areas, and at the same time, the second housing 30 can also be tightly assembled with the first housing 10 through the front cover 20. As follows, the present solution is further described through a specific structure.

[0051] Further references Figure 2 and Figure 3 In the shell assembly 001 provided by the present invention, the second shell 30 has a first position area, and the first position area is used to provide a first abutting force to prevent the first shell 10 from escaping upward from the second shell 30; the first abutting force here can be understood as an abutting force generated by an abutting relationship. Exemplarily, abutting includes snapping, buckling, etc., which realize the connection between the second shell 30 and the first shell 10 through the movement or sliding of the structural surfaces of the two components. Similarly, it can be understood that the second shell 30 abuts and buckles with the first shell 10 through the first position area, which belongs to the abutting connection mode between the second shell 30 and the first shell 10.

[0052] At the same time, the second housing 30 has a second position area, and the second position area is used to provide a second abutting force for preventing the front cover 20 from escaping upward from the second housing 30; the second abutting force here can be understood as an abutting force generated by an abutting relationship, and illustratively, the abutting includes snapping, buckling, etc., which realize the connection between the second housing 30 and the front cover 20 through the movement or sliding of the structural surfaces of the two components. Similarly, it can be understood that the second housing 30 abuts and buckles with the front cover 20 through the second position area, which belongs to the buckling connection mode between the second housing 30 and the front cover 20.

[0053] Further, the second housing 30 has a third position area, and the third position area is closely connected to the front cover; illustratively, the second housing 30 has a first plane portion 33, and the front cover 20 has a second plane portion 21, and the second plane portion 21 is located above the first plane portion 33, and the first plane portion 33 is closely connected to the second plane portion 21, refer to Figure 3 The fitting plane O3 in the figure. It should be pointed out that the fitting setting is to maintain the integral structure formed by the second shell 30 and the front cover 20, wherein one side of the second shell 30 is fitted with the wall, and the other side of the second shell 30 is fitted with the front cover 20. When the second shell 30 and one side of the wall are subjected to an external force toward the side of the front cover 20, the overall movement trend of the second shell 30 and the front cover 20 can be achieved. At the same time, due to the fitting setting between the two, there is no gap between the two, and the problem of uneven force between the two will not occur. In this way, the second shell 30 can achieve a state of close fitting between the second shell 30 and the front cover 20 through the fitting setting relationship between the first plane portion 33 and the second plane portion 21 of the front cover 20, without being affected by external forces.

[0054] In summary, the shell assembly of the present invention can ensure that the second shell 30 is always tightly assembled with the front cover 20 and the first shell 10. Exemplarily, when the shell assembly 001 of the present invention is in a state where the wall surface is uneven, the third position area of ​​the second shell 30 is used to directly bear the reaction force F1 of the raised position, and the reaction force F1 directly acts on the second shell 30, tending to push the second shell 30, the front cover 20 and the first shell 10 in the same direction, wherein the first abutting force and the second abutting force are opposite to the direction of the reaction force F1.

[0055] Specifically, under the premise of maintaining a tight fit between the first shell 10, the second 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), and when the blocking force (reaction force F1) acts on the second shell 30, the second shell 30 has a movement tendency toward the first shell 10, and along the direction of the movement tendency, the first shell 10 does not produce a blocking effect on the first position area of ​​the second shell 30, and along the direction of the movement tendency, the second shell 30 can fit the front cover 20 and simultaneously have a movement tendency in the same direction, and the front cover 20 will not fall off the second position area of ​​the second shell 30. In this way, the position areas having abutting assembly connection relationships between the second shell 30 and the first shell 10 and between the second shell 30 and the front cover 20 are not affected by external forces from protruding impurities on the wall, and a stable assembly state between the first shell 10, the front cover 20 and the second shell 30 can always be maintained, and the first shell 10 and the front cover 20 will not become loose or dispersed relative to the second shell 30.

[0056] like Figure 3 As shown, in the scheme of the abutment and engagement between the second housing 30 and the first housing 10, in order to achieve that there is no obstruction of the first housing 10 on the upper part of the second housing 30 in the engagement position area of ​​the two. In this scheme, the first position area of ​​the second housing 30 has a first protrusion 31, and the first housing 10 has a third protrusion 11. The first protrusion 31 abuts against the upper part of the third protrusion 11 to form a first abutment surface O1 ( Figure 3 In this way, it is possible to ensure that the reaction force F1 ( Figure 3 The second housing 30 will not act on the first contact surface O1, and thus will not affect the contact engagement state between the second housing 30 and the first housing 10 at the first contact surface O1.

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

[0058] To alleviate this problem, Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, in the scheme of the shell assembly 001 provided by the present scheme, the first protrusion 31 has a sliding surface 311, and the sliding surface 311 is used to guide the third protrusion 11 to slide to the bottom of the first protrusion 31, so that the third protrusion 11 is engaged with the first protrusion 31. Exemplarily, the sliding surface 311 can be an inclined surface or a curved surface, and correspondingly, the area of ​​the third protrusion 11 used to slide with the sliding surface 311 can also be an inclined surface or a curved surface, so that 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 to the bottom of the first protrusion 31 of the second shell 30. This assembly method can save the time of the alignment assembly of the first shell 10 relative to the second shell 30, and further realize the high efficiency of the engagement assembly process of the first shell 10 relative to the second shell 30.

[0059] In this embodiment, the shape and position of the protruding structures of the first protruding portion 31 of the second shell 30 and the third protruding portion 11 of the first shell 10 are not limited, as long as the second shell 30 and the first shell 10 are in a buckled abutting relationship at the first abutting surface O1, so that the second shell 30 and the first shell 10 will not be separated at this position. Exemplarily, the first protruding portion 31 can be a block structure, a columnar structure, or any three-dimensional structure protruding from its own outer wall, its own inner wall, or its own top wall, and matching, the third protruding portion 11 can also be a block structure, a columnar structure, or any three-dimensional structure protruding from its own inner wall, its own outer wall, or its own bottom wall.

[0060] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in the scheme of the abutment and engagement between the second housing 30 and the front cover 20, in order to achieve that there is no obstruction of the front cover 20 to the upper part of the second housing 30 in the engagement position area of ​​the two. In this scheme, the second position area of ​​the second housing 30 has a second protrusion 32, and the front cover 20 has a fourth protrusion 22. The second protrusion 32 abuts against the upper part of the fourth protrusion 22 to form a second abutment surface O2, and the second abutment force is formed on the second abutment surface O2. In this way, it can be ensured that the reaction force F1 generated by the protrusion position of the wall will not act on the second abutment surface O2 via the second housing 30, and thus will not affect the abutment and engagement state of the second housing 30 and the front cover 20 at the position of the second abutment surface O2.

[0061] In this embodiment, the shape and position of the protruding structure of the second protruding portion 32 of the second shell 30 and the fourth protruding portion 22 of the front cover 20 are not limited, as long as the second shell 30 and the front cover 20 are in a buckling and abutting relationship at the second abutting surface O2, so that the second shell 30 and the front cover 20 will not be separated at this position. Exemplarily, the second protruding portion 32 can be a block structure, a columnar structure or any three-dimensional structure protruding from the inner wall (inner side wall) of the second shell 30 itself or its own top wall or its own bottom wall. Matchingly, the fourth protruding portion 22 can also be a block structure, a columnar structure or any three-dimensional structure protruding from its own outer wall, its own inner wall or its own bottom wall. Taking the second protruding portion 32 protruding from the inner side wall of the second shell 30 as an example, correspondingly, the fourth protruding portion 22 protrudes from the outer side wall of the front cover 20, and the bearing groove 23 is formed on the outer side wall of the front cover 20.

[0062] In this embodiment, the front cover 20 is generally installed close to one side of the second housing 30, and the front cover 20 is arranged to protrude from the first housing 10. It can be understood that the front cover 20 is located between the first housing 10 and the second housing 30. In actual assembly scenarios, the first housing 10 with the front cover 20 needs to be assembled to the second housing 30 after the second housing 30 is assembled to the wall. In the actual installation process, the first housing 10 and the second housing 30 often have problems such as loose fastening or multiple fastenings.

[0063] To alleviate this problem, Figure 3 , Figure 4 and Figure 6 As shown, in the scheme of the shell assembly 001 provided by the present scheme, the front cover 20 has a bearing groove 23, the bearing groove 23 is connected to the upper part of the fourth protrusion 22, and the second protrusion 32 is guided and embedded into the bearing groove 23 along the inner wall of the bearing groove 23. Exemplarily, the bearing groove 23 can be a curved groove or a linear groove, and correspondingly, the area of ​​the fourth protrusion 22 used for sliding with the bearing groove 23 can also be a curved surface or an inclined surface, so that 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 embedded in the bearing groove 23, and / or the second protrusion 32 can abut against at least a part of the structure of the fourth protrusion 22, and the second protrusion 32 of the second shell 30 plays a guiding and clamping role, which can achieve a high efficiency of the clamping assembly process of the first shell 10 relative to the second shell 30.

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

[0065] In the scheme where the third position area of ​​the second shell 30 is fitted and connected with the front cover 20, the third position area of ​​the second shell 30 has a first plane portion 33, and the front cover 20 has a second plane portion 21, the second plane portion 21 is located above the first plane portion 33, and the first plane portion 33 and the second plane portion 21 are fitted together, so that it can be ensured that the second shell 30 drives the front cover 20 to move upward in the same direction. Exemplarily, there can be a pre-pressing force between the first plane portion 33 and the second plane portion 21, which can be understood as a pre-tightening force between the two planes. The pre-tightening force is used to maintain a balance with the first and second pressing forces in the buckled state.

[0066] In the actual assembly process, if the first protrusion 31 and the second protrusion 32 are symmetrically arranged relative to the center of the second housing 30, the first housing 10, the front cover 20 and the second housing 30 may be assembled unstably. This is because, when the first protrusion 31 and the second protrusion 32 are symmetrically arranged relative to the center of the second housing 30, the stresses borne on the first abutting surface O1 and the second abutting surface O2 may be coplanar. At this time, the stresses borne by the second housing 30 as a whole may be superimposed, which may be detrimental to the assembly stability of the shell assembly 001 as a whole.

[0067] In order to alleviate the above problem, the line connecting the center of the first protrusion 31 and the second shell 30 is the first line, and the line connecting the center of the second protrusion 32 and the second shell 30 is the second line, and the first line and the second line are set to be non-coplanar. In this way, it can be ensured that the arrangement of the first protrusion 31 and the second protrusion 32 relative to the second shell 30 is asymmetrical, thereby ensuring that the force of the first protrusion 31 and the second protrusion 32 relative to the second shell 30 is relatively dispersed, or that part of the force component of the first abutting force of the first protrusion 31 can offset part of the force component of the second abutting force of the second protrusion 32, thereby eliminating part of the unnecessary force in the structure of the second shell 30 itself, and will not act between the second shell 30 and the first shell 10 and between the second shell 30 and the front cover 20, thereby improving the service life of the overall shell assembly 001.

[0068] Considering the quick guide assembly of the front cover 20 relative to the first housing 10, as Figure 7 As shown, embedded plug structures 24 are set at the four corners of the front cover 20. The embedded plug structures 24 can be understood as guide plugs. Correspondingly, a guide installation groove is provided on the first shell 10. Based on the design of the embedded plug structure 24, the front cover 20 is fixed to the first 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 of the present invention can effectively improve the firmness of the snap fastenings of the first shell 10, the front cover 20 and the second shell 30 brackets, and can also prevent the problem of warping and easy popping caused by uneven wall surfaces, thereby ensuring the safety of the high-voltage module.

[0070] The shell assembly 001 provided by the present invention, considering its application in the field of smart home, also includes a touch panel, a steam-proof silicone pad, a strong electric module 50 and a partition 70, wherein the touch panel is bonded to one side of the first shell 10 through a glue drip groove, and the front cover 20 is assembled on the other side of the first shell 10, and a steam-proof silicone pad is arranged between the first shell 10 and the front cover 20. Generally speaking, the front cover 20 is equipped with a functional circuit board 53 and a row of pins connected to the functional circuit board 53, and the steam-proof silicone pad can prevent steam from damaging the components in the front cover 20. In addition, the strong electric module 50 is generally installed in the second shell 30, and the strong electric module 50 has a built-in circuit board 53, which is generally connected to the mother row. In this way, the strong electric module 50 is connected to the row of pins of the front cover 20 through the mother row, and the connection here includes physical clamping and electrical connection. The strong electric module 50 is connected to the wires extending from the wall through the conductive sheet 52, thereby providing electric energy to the strong electric module 50. The partition 70 is arranged between the high-voltage module 50 and the front cover 20 to avoid the risk of electric shock to the user during use. Considering the circuit connection and physical plug-in between the female header of the high-voltage module 50 and the pin header of the front cover 20, when the shell assembly 001 is in the snap-on state, the front cover 20 is spaced apart from the circuit board 53 of the high-voltage module 50 through the partition 70. Since there is a gap between the partition 70, the female header and the circuit board 53, the moisture in the wall will flow through the gap to the position where the pin header and the female header are connected, which may cause a short circuit in the line and affect the touch effect or circuit function of the central control panel 002. It should be further pointed out that the existing conductive sheet 52 needs to be screwed to abut the wire against one side of the conductive sheet 52 at the connection with the wire, and the problem of the screws crushing the conductive sheet 52 often occurs.

[0071] To alleviate the above problems, further reference Figure 1-Figure 11 The central control panel 002 provided by the present invention includes the aforementioned shell assembly 001, wherein the high-voltage module 50 includes a limit constraint assembly 51 and a circuit board 53 with a conductive sheet 52, wherein the conductive sheet 52 is inserted through the limit constraint assembly 51, and forms an adjustable accommodation space 54 for the insertion of the wiring harness with at least part of the structure of the limit constraint assembly 51, which is used to clamp and position the wiring harness on one side of the conductive sheet 52 along the circumferential direction. It should be noted that the limit constraint assembly 51 is mainly used to clamp and limit the wires extending from the wall relative to the conductive sheet 52, wherein the use of the limit constraint assembly 51 can avoid the direct pressure of the screws on the wiring harness (wires) and the conductive sheet 52. As follows, this scheme is explained through a specific structure.

[0072] In this embodiment, if Fig. 9 and Fig.10As shown, the position limiting and restraining assembly 51 includes a terminal buckle 511 and an adjusting member 512, wherein the terminal buckle 511 is sleeved on the outer periphery of the conductive sheet 52, and the adjusting member 512 passes through one side of the terminal buckle 511 and is gap-matched with the first side of the conductive sheet 52; in this way, a gap is left between the adjusting member 512 and the conductive sheet 52, and it will not directly press against the wire harness or the conductive sheet 52, and thus will not damage the wire harness or the conductive sheet 52. In addition, an accommodating space 54 for the wire harness to pass through is formed between the second side of the conductive sheet 52 and the inner wall of the terminal buckle 511; the accommodating space 54 here is the aforementioned adjustable accommodating space 54. The terminal buckle 511 is moved following the rotation of the adjusting member 512, and then the spatial size of the accommodating space 54 is adjusted during the rotation of the adjusting member 512.

[0073] Exemplarily, the conductive sheet 52 is a sheet-like structure that is plugged 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 assembly with the tail end of the adjustment member 512, and the raised area is used for electrical connection with the wiring harness.

[0074] Considering the actual assembly scenario of the above-mentioned limit constraint component 51, further reference is made to Fig. 9 A terminal accommodating cavity 34 is designed in the second shell 30, wherein the terminal accommodating 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 fall out of the terminal accommodating cavity 34 during the rotation process; the second limiting groove 342 is used to provide the terminal buckle 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 structure, the tail end of which is used to fit with the first side clearance of the conductive sheet 52, and the end structure 5121 thereof has a shoulder lift structure, which is convenient for limiting the adjusting member 512 through the shoulder lift structure. Specifically, the shoulder lift structure is installed in the first limiting groove 341 to prevent the adjusting member 512 from falling out of the terminal accommodating cavity 34, that is, the adjusting member 512 will not fall out of the second housing 30 having the terminal accommodating cavity 34. In addition, the second limiting groove 342 provides the terminal buckle 511 with sufficient space for the wiring harness to be inserted. Exemplarily, the second limiting groove 342 adopts a sleeve-shaped structure that is closed all around, and the terminal buckle 511, the conductive sheet 52 and the adjusting member 512 in the limiting constraint assembly 51 can be connected and fitted into the terminal accommodating cavity 34 along the opening on one side of the second limiting groove 342.

[0076] Exemplarily, one, two or more conductive sheets 52 can be plugged into the circuit board 53 of the high-voltage module 50 according to actual circuit requirements, and each conductive sheet 52 is used to be electrically connected to the wires extending from the wall. Correspondingly, the position limiting constraint assembly 51 of the present invention can also be adapted to be provided with one, two or more to ensure that each wire can be tightly connected to the corresponding conductive sheet 52, and that the wire or conductive sheet 52 will not be damaged due to stress concentration at a point. As follows, this solution is further described through a specific structure.

[0077] In this embodiment, a central control panel 002 with a limit constraint assembly 51 as above is used. During actual application, the terminal clip 511 in the limit constraint assembly 51 will be installed from one side of the terminal accommodating cavity 34 so that the shoulder structure of the adjustment member 512 can be installed in the first limit groove 341 of the terminal accommodating cavity 34. At the same time, the terminal clip 511 can be embedded in the second limit groove 342 of the terminal accommodating cavity 34.

[0078] Taking the adjustment part 512 as a screw as an example, the screw includes a screw head and a stud. In the present embodiment, the end structure 5121 of the screw includes a screw head and a shoulder structure. The screw head can adopt a hexagonal screw head. The shoulder structure is a protruding structure protruding from the outer wall of the stud, that is, the shoulder structure is a protruding structure extending in the opposite radial direction of the stud, and the outer wall of the shoulder structure needs to protrude from the outer wall of the screw head. Correspondingly, the structural outer wall of the terminal accommodating cavity 34 will not block the screw head from being twisted, and a safety gap is left between the terminal accommodating cavity 34 and the screw head. Furthermore, the terminal buckle 511 is accommodated in the second limiting groove 342. Since the limiting constraint component 51 in this scheme uses the twisting and rotation of the screw, and the terminal buckle 511 and the adjusting member 512 are in a threaded assembly relationship, the twisting and rotation of the adjusting member 512 can cause the terminal buckle 511 to move along the length direction of the screw stud, specifically including the movement of the terminal buckle 511 toward the direction close to the screw head and the movement of the terminal buckle 511 toward the original screw head. During the twisting and rotation of the screw and the movement of the terminal buckle 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 buckle 511 moves. Since the terminal buckle 511 adopts a rotating body structure, the insertion of the conductive sheet 52 into the terminal buckle 511 can form two spaces in the terminal buckle 511 during the movement, wherein one space is a first space between the raised area of ​​the conductive sheet 52 and the first inner wall of the terminal buckle 511 for clamping the wiring harness, and the other space is a second space between the recessed area of ​​the conductive sheet 52 relative to the second inner wall of the terminal buckle 511. The second space also includes a part of the stud that only rotates but does not move. Since a fixed clearance fit is always maintained between the tail end of the stud and the recessed area of ​​the conductive sheet 52 (combined with the first limiting groove 341), the reduction of the first space will correspond to the enlargement of the second space, and the enlargement of the first space will correspond to the reduction of the second space. That is, the first space is the aforementioned adjustable accommodating space 54 for the insertion of the wiring harness, and the internal space of the rotating body of the terminal buckle 511 cannot change during application.

[0079] The structure of the terminal buckle 511 currently used is a sleeve-shaped structure formed by a sheet metal bending process. It can be understood that the terminal buckle 511 is a rotating body structure with a mouth-shaped cross-section formed by bending a plate, which includes curved transition fillets at the four corners and forms a superimposed double-layer structure on one side. The limit constraint component 51 of the present invention involves the screwing and rotation of the screw during application. Since the position of the threaded connection between the screw and the terminal buckle 511 is in the double-layer structure, the stud of the screw passes through the outer and inner structural sides in turn during the screwing process. During the threaded connection with the outer structural side, the axial preload F2 of the screw acts on the outer structural side, and the outer structural side will generate an opposite force relative to the inner structural side. The direction of the opposite force is opposite to the direction of the axial preload F2 of the screw. This will cause the inner and outer structural sides to be in conflict with each other. There is a problem of movement in opposite directions relative to each other, and the inner layer structure side does not have any structural support on the side away from the outer layer structure side. Therefore, the inner layer structure side will move in the direction away from the stud side, and due to the molding process characteristics of the terminal buckle 511, the surfaces formed by its various bends are in an extended connection relationship, and there is an extended stress between the surfaces. When the aforementioned inner layer structure side is subjected to the opposite force, it will connect with other surface structures to move toward the side away from the conductive sheet 52, thereby causing the terminal buckle 511 to explode in the second limit space.

[0080] In order to alleviate the above problems, the terminal buckle 511 in this solution adjusts the structural composition of the terminal buckle 511 under the premise of applying the sheet metal bending process, and embeds part of the structure of the outer layer side 51111 into the adjacent structure side to avoid the formation of an opening between the outer layer side 51111 and the inner layer side of the double-layer structure, thereby avoiding the problem of the opening being blown open under the action of the opposing force. As follows, this solution is further explained through a specific structure.

[0081] In this embodiment, if Fig.10 and Fig.11As shown, the terminal buckle 511 is constructed as a rotating body structure, specifically a reel-like structure with a hollow interior. Exemplarily, the terminal buckle 511 can be any one of square, circular, trapezoidal or irregular shapes. Taking the terminal buckle 511 as an example of a square barrel structure, the terminal buckle 511 is made by bending and riveting. 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, a convex buckle structure 51112 extends from the outer layer side 51111. The convex buckle structure 51112 here can be understood as having a smaller size on the side close to its main body surface area and a larger size on the side away from its main body surface area. It should be noted that a single-layer structure side 5112 is provided next to the double-layer structure side 5111, and the single-layer structure side 5112 has a convex hole 51121. The convex buckle structure 51112 is bent and buckled with the convex hole 51121, so that the convex hole 51121 blocks the outer layer side 51111 from falling out. The terminal buckle 511 can effectively prevent the terminal from cracking during the installation process, increase the product life, and reduce the product maintenance cost.

[0082] Considering that the convex buckle structure 51112 and the convex hole 51121 can be buckled, and can form a contact surface for resisting the aforementioned opposite force. For the convex buckle structure 51112, the long side of the convex structure is used to abut against the inner wall of the convex hole 51121, so as to form a mutually abutting buckling relationship between the two side structures, and at the same time, the rotating body structure of the terminal buckle 511 will not be destroyed under the action of external force, that is, the terminal buckle 511 will not cause the problem of explosion.

[0083] Considering that the convex buckle structure 51112 can be accurately riveted into the convex hole 51121, the convex hole 51121 is defined as follows: along the direction away from the end structure 5121, the convex hole 51121 changes from small to large aperture. Matchingly, the long side of the convex buckle structure 51112 on the outer layer side 51111 is used to abut against the inner wall of the convex hole 51121, forming an abutment force on the abutment surface, which can be used to block the effect of the axial preload force F2 of the screw, ensuring that the convex buckle structure 51112 and the convex hole 51121 of this solution will not separate from each other, and further ensuring that the terminal buckle 511 will not explode under the effect of 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 be clearance fit and assembled with the recessed area of ​​the conductive sheet 52, and the adjusting member 512 is applied in the limiting and restraining assembly 51 to be screwed and rotated. Further considering the installation and application stability of the adjusting member 512 in the limiting and restraining assembly 51 and the terminal accommodating 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, which can also prevent the screw from being separated from the corresponding support surface on the terminal accommodating cavity 34 and shaking during the screwing and rotation of the adjusting member 512.

[0085] In this embodiment, further reference is made to Fig. 9 , the tail end of the adjusting member 512 can be constructed as a round head structure, and the round head structure is gap-matched with the first side of the conductive sheet 52. In this way, during the screwing and rotating process of the adjusting member 512, the round head structure at the tail end thereof can always maintain the gap assembly relative to the first side of the conductive sheet 52 due to the structure of a rotating body, further preventing the problem of the adjusting member 512 (screw or bolt) crushing the conductive sheet 52 during the engineering installation process. Exemplarily, the tail end of the adjusting member 512 is constructed as a curved surface near the side of the recessed area of ​​the conductive sheet 52, and the gap between the curved surface and the recessed area on the conductive sheet 52 can be an equal gap or an unequal gap. 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 an unequal gap, it is sufficient to ensure that the curved surface within the preset radius area of ​​the center of the stud and the curved surface at the tail end of the adjusting member 512 are equal gaps. This solution does not limit the range of the preset radius area, and is subject to the needs of the actual installation scenario.

[0086] Constructing the tail end of the adjusting piece 512 as a round head structure can avoid large changes in the size of the stud and the tail end of the adjusting piece 512, and thus avoid the occurrence of large chamfers or large cone angles. Because the side of the terminal buckle 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 to cooperate with the gap of the tail end of the stud, the terminal buckle 511 will be extremely close to the conductive sheet 52 in a certain state, and the terminal buckle 511 has a certain thickness. Therefore, in order to avoid shaking between the conductive sheet 52 and the terminal buckle 511, the stud and the tail end of the adjusting piece 512, the radial size between the stud and the tail end of the adjusting piece 512 should be changed as slowly as possible, which can avoid shaking connection between the terminal buckle 511 and the stud.

[0087] In summary, the scheme of the shell assembly 001 and the central control panel 002 of the present invention can prevent the problems of disconnection between the components of the shell assembly 001 and loose connection terminals caused by uneven wall surfaces. At the same time, the central control panel 002 with the high-voltage module 50 can also restrain the wiring harness of the docking wall, and will not cause the adjusting member 512 (screws or studs) to directly press and damage the wiring harness and the conductive sheet 52. Furthermore, with the application of the new terminal buckle 511 structure, the terminal buckle 511 will not explode in the second limiting groove 342 of the terminal accommodating cavity 34 in the second shell 30, and will not cause collision damage to the terminal accommodating cavity 34 and the second shell 30, thereby improving the service life of the shell assembly 001 and the central control panel 002 as a whole.
