Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air conditioners, in particular to an electric control box component and an air conditioner. Background Art
[0002] For air conditioners, air conditioner manufacturers usually use screws to fix the terminal board in the middle. When installing the terminal board, first position the terminal board and the sheet metal, and then screw the terminal board into the sheet metal through the screw positioning hole. However, in the actual production process, the terminal board may be installed and the external force of the wind screw may crack the round seat under the screw positioning hole, resulting in insufficient electrical clearance between the screw and the plug, which is easy to spark and eventually cause air conditioner failure. In addition, the assembly of screws will consume a lot of time and labor.
[0003] Therefore, designing an electric control box that does not require screws to fix the terminal board has certain significance from the perspectives of installation, service life, stability, etc. Utility Model Content
[0004] The utility model aims to provide an electric control box assembly with a novel installation structure free of screws, and realizes the installation connection of the terminal board by designing a positioning piece, thereby achieving the purpose of improving the installation stability.
[0005] To achieve the above-mentioned purpose, the utility model provides an electric control box assembly, including: a shell, the shell is used to install a main control board; a terminal board, the terminal board is fixed on the shell and connected to the main control board; a positioning member, the positioning member includes a positioning column and a clip arranged at one end of the positioning column, and is used to fix the shell and the terminal board; wherein the terminal board is provided with a first positioning hole, and the shell is provided with a second positioning hole, the positioning column and the first positioning hole cooperate with each other, and the clip is clamped in the second positioning hole.
[0006] The electric control box assembly provided by the utility model has a positioning column that matches the terminal board through the first positioning hole, and a buckle that is connected to the shell through the second positioning hole, thereby ensuring a fixed connection between the shell and the terminal board. The design of the positioning column and the buckle makes the assembly process simpler and reduces the assembly time and labor costs; this structure can ensure a stable connection between the shell and the terminal board, and improve the reliability and stability of the entire electric control box assembly. The design of the first positioning hole and the second positioning hole ensures the precise positioning of the terminal board and the shell during the assembly process, reduces errors, and improves the quality and consistency of the product. After the assembly is completed, at this time, unless the buckle is squeezed by external force, the terminal board will not fall out of the shell. In general, the positioning piece can effectively prevent the terminal board from being cracked by external force during installation and air screwing, resulting in insufficient electrical clearance, thereby reducing certain safety hazards.
[0007] In any of the above technical solutions, the buckle includes a plurality of stop walls, the stop walls extend in a circumferential direction away from the positioning column, and the stop walls abut against the second positioning hole.
[0008] The stop wall added to the buckle is a protruding structure, extending outward from the main body of the buckle, so as to enhance the fixing ability of the buckle. The function of the stop wall is to provide additional support and resistance when the buckle is engaged with the second positioning hole, increase the contact area between the buckle and the shell, and thus improve the stability and safety of the connection; the stop wall abuts against the inner side of the second positioning hole, so that the buckle and the second positioning hole are more closely matched, preventing the buckle from loosening or shifting during use.
[0009] In any of the above technical solutions, the diameter of the circle where the stop wall is located is greater than the diameter of the second positioning hole.
[0010] The diameter of the stop wall is larger than the diameter of the second positioning hole, so that the stop wall can be closely contacted with the edge of the hole when inserted into the second positioning hole. The tight fit of the physical structure enhances the locking effect of the buckle, thereby improving the stability of the overall connection. Under vibration or stress, the larger stop wall can better prevent the buckle from loosening or slipping out of the second positioning hole, which is particularly important for ensuring reliability in long-term use. A larger stop wall diameter means more contact area, which can disperse the pressure of the contact point and reduce the wear that may occur during long-term use, thereby improving the durability of the overall structure.
[0011] In any of the above technical solutions, a groove extending along the axial direction is provided on the surface of the positioning column, and a convex wall is provided at the first positioning hole, and the groove and the convex wall cooperate with each other to fix the positioning member to the terminal board.
[0012] The surface of the positioning column is designed with a groove extending in the axial direction, which can fix the positioning piece. On the terminal board, a convex wall is provided at the position corresponding to the groove of the positioning column. The convex wall cooperates with the groove of the positioning column, so that the positioning piece can be accurately positioned and fixed on the terminal board, which improves the stability of the connection and reduces the possibility of loosening. In addition, the cooperation between the groove and the convex wall improves the tightness of the connection and reduces the loosening caused by vibration or other external forces during use, thereby enhancing the durability of the product. The simplified assembly process makes it easier for assemblers to correctly install the positioning piece on the terminal board, reducing operational errors during the assembly process.
[0013] In any of the above technical solutions, the positioning column is provided with an annular wall covering at least a portion of the surface of the positioning column, and the groove is provided on the annular wall.
[0014] The positioning column is designed with an annular wall covering at least part of the surface, and the annular wall structure surrounds the outer surface of the positioning column to form an additional layer or component. The addition of the annular wall increases the overall structural strength of the positioning column, especially when subjected to lateral pressure or impact, which helps to maintain its structural integrity. By providing grooves on the annular wall, more fixing points can be provided, thereby more accurately and stably installing the positioning piece, ensuring the safety and stability of the connecting piece, and further, it can be convenient for operators to install and fix, and improve the flexibility of assembly.
[0015] In any of the above technical solutions, a slot is provided between the buckle and the annular wall, and the slot is used to accommodate the peripheral portion of the second positioning hole.
[0016] A specific slot is provided between the buckle and the ring wall, which can accommodate the peripheral portion of the second positioning hole, thereby realizing the connection between the buckle and the ring wall. By adding a slot between the buckle and the ring wall, the buckle can be more firmly fixed, thereby improving the stability and reliability of the connection and reducing the possibility of assembly errors. The slot can effectively protect the peripheral portion of the second positioning hole, reduce the wear and damage caused by friction and collision during the assembly process, and extend the service life of the parts. The design of the slot makes the assembly process simpler and faster, because the operator can more easily align the buckle with the ring wall correctly and install it in place.
[0017] In any of the above technical solutions, the terminal board is provided with a protrusion, and the housing is provided with a recess that cooperates with the protrusion.
[0018] The terminal board is designed with one or more raised block structures, which are used to cooperate with the recessed parts in the shell, so that the terminal board can be accurately positioned at a specific position inside the shell during the assembly process, thereby ensuring the correct installation and function realization of the components, and also reducing the difficulty and time of assembly, and reducing the possibility of assembly errors. In addition, displacement caused by vibration or external impact is also reduced to a certain extent. Using this positioning method can reduce the need for other complex connectors, such as screws or adhesives, thereby reducing material costs and processing costs.
[0019] In any of the above technical solutions, the shell is a sheet metal structure.
[0020] By selecting appropriate metal materials and thickness, the sheet metal shell can provide excellent mechanical strength and durability, and is suitable for the housing of electronic or electrical equipment that requires durability. Due to the plasticity of sheet metal, the design of the shell can take into account the convenience of assembly in advance, such as preset bending edges and interfaces, simplifying the assembly process and reducing production costs. The utility model needs to open a second positioning hole on the shell for the installation of the positioning piece; the size of the buckle is larger than the second positioning hole, and the sheet metal material has excellent mechanical strength, which can effectively avoid damage to the second positioning hole during the installation of the positioning piece.
[0021] In any of the above technical solutions, the first positioning hole is arranged at a relatively middle position of the terminal board.
[0022] By setting the first positioning hole at a relatively middle position of the terminal board, on the one hand, the convenience of installation is improved. On the basis of using only one positioning piece, the positioning hole is set at the middle position, which is convenient for operators to assemble. On the other hand, setting it at the middle position helps to ensure the stability of the component and reduce the risk of failure or damage caused by position deviation.
[0023] The utility model also provides an air conditioner, which includes the electric control box assembly as described above. The air conditioner has the same beneficial effects as the electric control box assembly, so it will not be described in detail here.
[0024] After adopting the technical solution of the utility model, the following technical effects can be achieved:
[0025] (1) Easy assembly: The design of positioning columns and buckles makes the assembly process simpler, reducing assembly time and labor costs;
[0026] (2) Stable connection: The structure of the positioning column and the buckle can ensure a stable connection between the housing and the terminal board, improving the reliability and stability of the entire electric control box assembly;
[0027] (3) Precise positioning: The design of the positioning holes can ensure the precise positioning of the terminal board and the housing during the assembly process, reducing errors and improving product quality and consistency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0041] An embodiment of the utility model provides an electric control box assembly, including: a shell 100, the shell 100 is used to install a main control board; a terminal board 200, the terminal board 200 is fixed on the shell 100 and connected to the main control board; a positioning member 300, the positioning member 300 includes a positioning column 310 and a buckle 320 arranged at one end of the positioning column 310, and is used to fix the shell 100 and the terminal board 200. The terminal board 200 is provided with a first positioning hole 210, and the shell 100 is provided with a second positioning hole 110, the positioning column 310 cooperates with the first positioning hole 210, and the buckle 320 is snapped into the second positioning hole 110.
[0042] like Figures 1 to 3As shown, in the electric control box assembly provided by the utility model, the positioning column 310 matches the terminal board 200 through the first positioning hole 210, and the buckle 320 is clamped on the housing 100 through the second positioning hole 110, thereby ensuring the fixed connection between the housing 100 and the terminal board 200. The design of the positioning column 310 and the buckle 320 makes the assembly process simpler, reducing the assembly time and labor cost; the structure can ensure the stable connection between the housing 100 and the terminal board 200, and improve the reliability and stability of the entire electric control box assembly. The design of the first positioning hole 210 and the second positioning hole 110 ensures the precise positioning of the terminal board 200 and the housing 100 during the assembly process, reduces errors, and improves the quality and consistency of the product. After the assembly is completed, at this time, unless the buckle 320 is squeezed by external force, the terminal board 200 will not fall out of the housing 100. In general, the positioning member 300 can effectively prevent the terminal board 200 from being cracked by external force during installation and wind, thereby reducing certain safety hazards.
[0043] In some embodiments of the present application, the buckle 320 includes a plurality of stop walls 321 . The stop walls 321 extend in a circumferential direction away from the positioning column 310 , and the stop walls 321 abut against the second positioning hole 110 .
[0044] like Figure 3 As shown, the stop wall 321 added to the buckle 320 is a protruding structure, extending outward from the main body of the buckle 320, so as to enhance the fixing ability of the buckle 320. The function of the stop wall 321 is to provide additional support and resistance when the buckle 320 is connected to the second positioning hole 110, increase the contact area between the buckle 320 and the housing 100, thereby improving the stability and safety of the connection; the stop wall 321 abuts against the inner side of the second positioning hole 110, so that the buckle 320 and the second positioning hole 110 are more closely matched, preventing the buckle 320 from loosening or shifting during use. Specifically, the stop wall 321 abuts against the circumferential edge of the second positioning hole 110, and the circumferential edge is located on the side of the housing 100 away from the terminal board 200.
[0045] In some embodiments of the present application, the diameter of the circle where the stopping wall 321 is located is greater than the diameter of the second positioning hole 110 .
[0046] like Figures 3 to 5As shown, the diameter of the stop wall 321 is larger than the diameter of the second positioning hole 110, so that the stop wall 321 can be closely contacted with the edge of the hole when inserted into the second positioning hole 110. The locking effect of the buckle 320 is enhanced through the close fit of the physical structure, thereby improving the stability of the overall connection. Under the action of vibration or stress, the larger stop wall 321 can better prevent the buckle 320 from loosening or slipping out of the second positioning hole 110, which is particularly important for ensuring reliability in long-term use. A larger diameter of the stop wall 321 means more contact area, which can disperse the pressure of the contact point and reduce the wear that may occur during long-term use, thereby improving the durability of the overall structure. Preferably, two stop walls 321 can be provided to improve the stability of the installation.
[0047] In some embodiments of the present application, a groove 311 extending along the axial direction is provided on the surface of the positioning column 310 , and a convex wall 211 is provided at the first positioning hole 210 . The groove 311 and the convex wall 211 cooperate with each other to fix the positioning member 300 to the terminal board 200 .
[0048] like Figure 2 and Figure 3 As shown, the surface of the positioning column 310 is designed with a groove 311 extending along the axial direction, which can fix the positioning member 300. On the terminal board 200, a convex wall 211 is provided at a position corresponding to the groove 311 of the positioning column 310, and the convex wall 211 cooperates with the groove 311 of the positioning column 310, so that the positioning member 300 can be accurately positioned and fixed on the terminal board 200, thereby improving the stability of the connection and reducing the possibility of loosening. In addition, the cooperation between the groove 311 and the convex wall 211 improves the tightness of the connection, reduces the loosening caused by vibration or other external forces during use, and thus enhances the durability of the product. The simplified assembly process allows the assembler to more easily and correctly install the positioning member 300 on the terminal board 200, reducing operational errors during the assembly process.
[0049] In some embodiments of the present application, the positioning post 310 is provided with an annular wall 312 covering at least a portion of the surface of the positioning post 310 , and the groove 311 is provided on the annular wall 312 .
[0050] like Figure 3 and Figure 4As shown, the positioning column 310 is designed with an annular wall 312 covering at least part of the surface, and the annular wall 312 structure surrounds the outer surface of the positioning column 310 to form an additional layer or component. The addition of the annular wall 312 increases the overall structural strength of the positioning column 310, especially when subjected to lateral pressure or impact, which helps to maintain its structural integrity. By providing a groove 311 on the annular wall 312, more fixing points can be provided, thereby more accurately and stably installing the positioning member 300, ensuring the safety and stability of the connecting member. Further, it can be convenient for operators to install and fix, and the flexibility of assembly is improved.
[0051] like Fig. 9 and Fig.10 As shown, specifically, the area on the positioning column 310 not covered by the annular wall 312 cooperates with the first positioning hole 210, and the area covered by the annular wall 312 is provided with a groove 311, and the groove 311 cooperates with the convex wall 211 on the terminal board 200 near the first positioning hole 210, and finally realizes the connection between the positioning column 310 and the terminal board 200. The provision of the annular wall 312 facilitates the operator to cooperate the groove 311 with the convex wall 211, thereby reducing a certain degree of installation difficulty.
[0052] In some embodiments of the present application, a slot 330 is provided between the buckle 320 and the annular wall 312 , and the slot 330 is used to accommodate the peripheral portion of the second positioning hole 110 .
[0053] like Figure 4 As shown, a specific slot 330 is provided between the buckle 320 and the annular wall 312, which can accommodate the peripheral portion of the second positioning hole 110, so as to realize the connection between the buckle 320 and the annular wall 312. By adding the slot 330 between the buckle 320 and the annular wall 312, the buckle 320 can be more firmly fixed, thereby improving the stability and reliability of the connection and reducing the possibility of assembly errors. The slot 330 can effectively protect the peripheral portion of the second positioning hole 110, reduce the wear and damage caused by friction and collision during the assembly process, and extend the service life of the parts. The design of the slot 330 makes the assembly process simpler and faster, because the operator can more easily align the buckle 320 with the annular wall 312 correctly and install it in place.
[0054] In some embodiments of the present application, the terminal board 200 is provided with a protrusion 220 , and the housing 100 is provided with a recess 120 that cooperates with the protrusion 220 .
[0055] like Figure 2 , Figures 7 to 10As shown, the terminal board 200 is designed with one or more raised block structures, and these protrusions 220 are used to cooperate with the recessed 120 part in the housing 100, so that the terminal board 200 can be accurately positioned at a specific position inside the housing 100 during the assembly process, thereby ensuring the correct installation and function realization of the components, and also reducing the difficulty and time of assembly, and reducing the possibility of assembly errors. In addition, the displacement caused by vibration or external impact is also reduced to a certain extent. Using this positioning method can reduce the need for other complex connectors, such as screws or adhesives, thereby reducing material costs and processing costs.
[0056] In some embodiments of the present application, the housing 100 is a sheet metal structure.
[0057] like Figures 6 to 8 As shown, by selecting appropriate metal materials and thicknesses, the sheet metal housing 100 can provide excellent mechanical strength and durability, and is suitable for the housing of electronic or electrical equipment that requires durability. Due to the plasticity of sheet metal, the design of the housing 100 can take into account the convenience of assembly in advance, such as preset bending edges and interfaces, simplifying the assembly process and reducing production costs. Specifically, in this embodiment, it is necessary to open a second positioning hole 110 on the housing 100 for the installation of the positioning member 300; the size of the buckle 320 is larger than the second positioning hole 110, and the sheet metal material has excellent mechanical strength, which can effectively avoid damage to the second positioning hole 110 during the installation of the positioning member 300.
[0058] In some embodiments of the present application, the first positioning hole 210 is disposed at a relatively middle position of the terminal board 200 .
[0059] like Figure 2 As shown, by arranging the first positioning hole 210 at a relatively middle position of the terminal board 200, on the one hand, the convenience of installation is improved. On the basis of using only one positioning member 300, the positioning hole is arranged at the middle position, which is convenient for operators to assemble; on the other hand, arranging it at the middle position helps to ensure the stability of the component and reduce the risk of failure or damage caused by position deviation.
[0060] The embodiment of the utility model further provides an air conditioner, which includes the electric control box assembly as described above. The air conditioner has the same beneficial effects as the electric control box assembly, so it will not be described in detail here.
[0061] Although the utility model is disclosed as above, the utility model is not limited thereto.
