For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] The following is combined with Figures 1 to 5 The technical solution of the utility model is further illustrated by specific implementation methods.

[0038] A connection structure of a spliced ​​housing, comprising a cover 1 and an extension cover 2, wherein one of the cover 1 and the extension cover 2 is provided with a first male buckle, and the other of the cover 1 and the extension cover 2 is provided with a first female buckle, and the first male buckle is matched and connected with the first female buckle;

[0039] The first male buckle is a protrusion 31 protruding outward along the X direction, and the first female buckle is a groove 41 recessed inward along the X direction. The groove 41 is extended along the Y direction. The protrusion 31 slides into the groove 41 from a side groove through hole of the groove 41 along the Y direction and is installed in the groove 41. When the protrusion 31 is installed in the groove 41, the protrusion 31 cannot be separated from the groove 41 in the opposite direction of the X direction, and the surface cover 1 and the extension cover 2 are connected.

[0040] The utility model provides a shell connection structure, which achieves the effect of lengthening the shell by adding an extension cover 2 to a face cover 1. One of the face cover 1 and the extension cover 2 is provided with a first male buckle, and the other is provided with a first female buckle; wherein the first male buckle is a convex block 31, and the first female buckle is a groove 41. Through the matching connection of the convex block 31 and the groove 41, the face cover 1 and the extension cover 2 can be locked and assembled without using fasteners such as bolts, making the assembly and disassembly of the assembled shell very convenient.

[0041] Specifically, the protrusion 31 is a structure protruding outward along the X direction, and the groove 41 is a structure recessed inward along the X direction. The protrusion 31 slides into the groove 41 along the opening direction of the groove 41 (the second direction Y) through a slot hole on one side of the groove 41, so as to realize the installation of the protrusion 31 and the groove 41; once the protrusion 31 slides into the groove 41, it cannot be separated from the groove 41 in the opposite direction of the X direction, thereby ensuring the stability of the spliced ​​shell. It is worth noting that the direction extending in the X direction is the lengthening direction of the spliced ​​shell.

[0042] By setting the first male buckle (bump 31) and the second female buckle (groove 41) of the sliding assembly on the cover 1 and / or the extension cover 2, the extension cover 2 of different lengths can be selected as needed to be spliced ​​to the cover 1, and the splicing obtains a lengthened shell to meet the application scenarios of different needs, thereby improving the versatility and adaptability of the shell. Compared with the traditional bolt connection installation method, this sliding male and female buckle design is neater and more beautiful in appearance, without exposed bolt heads or nuts, which improves the overall texture of the product. At the same time, this design also reduces the safety hazards caused by loose or falling bolts.

[0043] Further, the protrusion 31 is a trapezoidal protrusion, the short side of the trapezoidal protrusion is connected to one of the surface cover 1 and the extension cover 2, the two waists of the trapezoidal protrusion extend outwards relatively, and the line connecting the two extension ends is the long side of the trapezoidal protrusion;

[0044] The shape of the groove 41 matches the trapezoidal protrusion.

[0045] By designing the protrusion 31 as a trapezoidal protrusion and making the connecting line of the two waists of the trapezoidal protrusion extending outwards relatively form the long side, the contact area between the protrusion 31 and the groove 41 is larger, thereby enhancing the stability of the connection.

[0046] Furthermore, the long side of the trapezoidal protrusion is used to fit with the bottom of the groove 41 .

[0047] The long side of the trapezoidal protrusion serves as the main contact surface with the groove 41. This design prevents the protrusion 31 from being pulled out of the groove 41 in the opposite direction of the X direction, and can effectively prevent the spliced ​​housing from accidentally falling off even without an additional locking mechanism.

[0048] Further, the face cover 1 includes a face cover plate 11 and a face cover frame 12, the face cover frame 12 is extended in the opposite direction of the Y direction and is arranged at the edge of one side of the face cover plate 11, forming a face cover 1 with an opening, the first female buckle is arranged on the face cover frame 12, and the outer side of the face cover frame 12 is recessed inwardly along the X direction to form the groove 41;

[0049] The extended cover 2 includes an extended cover panel 21, a first extended cover side panel 22, a second extended cover side panel 23 and two extended cover end panels, the first extended cover side panel 22 and the second extended cover side panel 23 are arranged relatively parallel, and the two extended cover end panels are arranged relatively parallel on both sides of the first extended cover side panel 22 and the second extended cover side panel 23, the first extended cover side panel 22, the second extended cover side panel 23 and the two extended cover end panels are extended along the opposite direction of the Y direction to the edge of one side of the extended cover panel 21 to form an extended cover 2 with an opening, the first male buckle is arranged on the first extended cover side panel 22, the outer side of the first extended cover side panel 22 protrudes outward along the X direction to form the protrusion 31, and the short side of the protrusion 31 is connected to the outer side of the first extended cover side panel 22.

[0050] The face cover frame 12 is arranged along the edge of one side of the face cover plate 11 to form the face cover 1, so that the face cover 1 has the function of covering the shell opening. When the inverter becomes larger due to the demand for capacity or power, the extended cover 2 is spliced ​​on the face cover 1 to obtain an extended shell. In order to meet the function of covering the shell, the extended cover 2 is composed of a first extended cover side plate 22, a second extended cover side plate 23 and two extended cover end plates arranged along the edge of one side of the extended cover panel 21. The first male buckle (bump 31) is arranged on the outside of the first extended cover side plate 22 of the extended cover 2, and the first female buckle (groove 41) is arranged on the outside of the face cover frame 12 of the face cover 1. When assembling, the face cover 1 and the extended cover 2 are displaced front and back, and the bump 31 of the extended cover 2 is aligned with the side groove through hole of the groove 41 of the face cover 1, and the bump 31 is slid into the groove 41 by relative sliding to complete the assembly.

[0051] Furthermore, the groove 41 is located at one end of the cover frame 12 away from the cover plate 11 along the Y direction, the length of the groove 41 is less than the length of the cover frame 12 along the Y direction, and one end slot through hole of the groove 41 is located at one end away from the cover plate 11;

[0052] The protrusion 31 is located at one end of the first extended cover side plate 22 away from the extended cover panel 21 along the Y direction, and the length of the protrusion 31 is less than the length of the first extended cover side plate 22 along the Y direction;

[0053] After the groove 41 and the protrusion 31 are assembled and installed, the surface cover plate 11 and the extended cover plate 21 are located in the same plane.

[0054] The groove 41 is located along the Y direction at one end of the face cover frame 12 away from the face cover plate 11, and the groove 41 has only one side of the groove through hole, so the protrusion 31 can only slide into the groove 41 from one side of the groove through hole; at the same time, since the groove 41 does not penetrate the face cover frame 12 in the Y direction, the protrusion 31 will have an in-position / limit reminder in the groove 41; this is equivalent to the protrusion 31 only being able to slide into the groove 41 from one side for assembly, and can only slide out of the through groove 41 from this side for disassembly, which further improves the stability of the spliced ​​shell.

[0055] After the groove 41 and the protrusion 31 are assembled and installed, the surface cover plate 11 and the extended cover panel 21 can be in the same plane, which not only ensures the flatness of the shell, but also makes the shell look more beautiful and improves the overall texture of the product.

[0056] Furthermore, the cover frame 12 is provided with a plurality of grooves 41, and the plurality of grooves 41 are arranged parallel to each other;

[0057] The first extended cover side plate 22 is provided with a plurality of protrusions 31, and the plurality of protrusions 31 are arranged parallel to each other;

[0058] The groove 41 and the protrusion 31 cooperate with each other to achieve assembly.

[0059] By providing multiple grooves 41 and protrusions 31 and achieving one-to-one matching during assembly, the stability of the shell connection structure can be significantly enhanced. This multi-point connection method can disperse the force and prevent deformation or damage caused by excessive force on a single point, thereby improving the durability and reliability of the overall structure.

[0060] In addition, the arrangement of multiple grooves 41 and protrusions 31 provides more reference points and positioning benchmarks for the installation process, which helps to improve the installation accuracy and ensure that the cover 1 and the extension cover 2 can be connected accurately and quickly. At the same time, this design also reduces the errors and deviations that may occur during the installation process.

[0061] Furthermore, it also includes a second male buckle and a second female buckle that are engaged with each other, the second male buckle is an elastic block 32, and the second female buckle is a clamping hole 42;

[0062] The locking hole 42 is disposed on the face cover frame 12 , and the elastic locking block 32 is disposed on the first extended cover side plate 22 . When the protrusion 31 is slidably assembled with the groove 41 , the elastic locking block 32 is locked in the locking hole 42 .

[0063] On the basis of the original sliding assembly of the protrusion 31 and the groove 41, the elastic block 32 and the clamping hole 42 are added to form a double locking mechanism. This design greatly enhances the stability and safety of the shell connection structure, and effectively prevents the shell from accidentally separating under vibration or impact. Due to its own elastic characteristics, the elastic block 32 can provide a certain pre-tightening force when it is inserted into the clamping hole 42, thereby ensuring a tight connection between the shells.

[0064] During assembly, the user only needs to slide the protrusion 31 into the groove 41 and ensure that the elastic block 32 is smoothly inserted into the hole 42 to complete the installation. This design simplifies the installation steps, improves the installation efficiency, and reduces the difficulty of use for the user.

[0065] Furthermore, the clamping hole 42 penetrates the cover frame 12 along the X direction;

[0066] The elastic block 32 includes a fixed end 321 and a movable end 322, wherein the fixed end 321 is an end close to the extended cover panel 21, and the fixed end 321 is fixedly connected to the first extended cover side plate 22, and the movable end 322 is an end away from the extended cover panel 21, and the movable end 322 can move relative to the first extended cover side plate 22 in the X direction, and the movable end 322 protrudes from the outer surface of the first extended cover side plate 22;

[0067] When the protrusion 31 slides into the groove 41 for assembly, the elastic block 32 is locked in the locking hole 42 .

[0068] The design of the elastic block 32 allows the movable end 322 to move relative to the first extended cover side plate 22 in the X direction. During assembly, the movable end 322 can be compressed and deformed to adapt to the entrance of the clamping hole 42, and then elastically restored to the original state and firmly clamped in the clamping hole 42.

[0069] During installation, first, the protrusion 31 of the extended cover 2 is placed in front of the groove through hole of the groove 41 of the face cover 1 to achieve the alignment of the first male buckle and the first female buckle. After the alignment, the extended cover 2 slides relative to the face cover 1 to make the protrusion 31 slide into the groove 41; during the relative sliding process, the outer surfaces of the face cover frame 12 and the first extended cover side plate 22 contact each other and slide relative to each other, but the movable end 322 of the elastic clamping block 32 protrudes from the outer surface of the first extended cover side plate 22. Therefore, when the face cover frame 12 slides relatively to the movable end 322, the movable end 322 will be squeezed in the opposite direction of the first direction X. When the movable end 322 moves to the clamping hole 42, the movable end 322 of the elastic clamping block 32 is reset to the X direction and is clamped in the clamping hole 42. When disassembly is required, since the locking hole 42 penetrates the cover frame 12 in the X direction, the movable end 322 of the elastic locking block 32 is pressed from the other end of the locking hole 42 to disengage it from the locking hole 42, and the protrusion 31 is withdrawn from the groove 41 to complete the disassembly.

[0070] Furthermore, the height of the portion of the elastic block 32 protruding from the outer surface of the first extended cover side plate 22 gradually increases from the direction close to the extended cover panel 21 to the direction away from the extended cover panel 21 .

[0071] The movable end 322 of the elastic pressing block 32 protrudes from the first extended cover side plate 22 and gradually becomes larger, which is equivalent to being gradually larger in the form of an inclined surface. When the movable end 322 of the inclined surface slides relatively with the cover 1 and the extended cover 2 to achieve assembly, the outer side surface of the cover frame 12 and the outer surface of the first extended cover side plate 22 slide relatively more smoothly, and the movable end 322 of the elastic pressing block 32 will not protrude abruptly from the outer surface of the first extended cover side plate 22 to affect assembly.

[0072] Furthermore, the second extended cover side plate 23 is provided with the groove 41 and the card hole 42, the groove 41 is located along the Y direction at the end of the face cover frame 12 away from the face cover plate 11, the length of the groove 41 is smaller than the length of the face cover frame 12 along the Y direction, and the groove through hole at one end of the groove 41 is located at the end away from the face cover plate 11.

[0073] A groove 41 and a clamping hole 42 are provided on the outer side of the second extension cover side plate 23 opposite to the first extension cover side plate 22, so that in addition to being spliced ​​with the surface cover 1 through the first male buckle and the second male buckle, the extension cover 2 can also be spliced ​​with another extension cover 2 on the other side, making the extension cover 2 more versatile.

[0074] Furthermore, the surface cover 1 is integrally formed with the groove 41 and the clamping hole 42;

[0075] The extension cover 2 is integrally formed with the protrusion 31 , the elastic clamping block 32 , the groove 41 and the clamping hole 42 .

[0076] The one-piece design can significantly improve the structural strength of the cover 1 and the extension cover 2, and the overall strength of the assembled shell is also higher. Since there are no seams or connection points between the various components, the structural weaknesses caused by loose connections are reduced.

[0077] The one-piece design simplifies the production process and reduces the steps of assembly and connection. This not only improves production efficiency, but also reduces production costs. At the same time, the one-piece design also reduces quality problems caused by improper assembly.

[0078] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
