[0055] The housing, distribution box and battery pack provided in the embodiments of the present invention are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0056] Reference Figure 1-Figure 2 The embodiment of the utility model provides a shell 10, which includes a plurality of splicing modules 100, each of which is provided with a splicing portion 101, and a plurality of splicing modules 100 are spliced ​​together through the splicing portion 101 to form the shell 10; the plurality of splicing modules 100 include a first type module 110, and the first type module 110 is also provided with a component mounting structure 111, and the component mounting structure 111 is used to mount components.

[0057] Specifically, refer to Figure 1 The shell 10 includes a variety of building block-like splicing modules 100, and the specific types of the various splicing modules 100 can be flexibly set according to the assembly requirements and assembly space after the shell 10 is finally spliced ​​and formed. The production method of the various splicing modules 100 can be open mold injection molding or machine processing, which is not limited by the embodiment of the utility model. Each splicing module 100 is provided with a splicing portion 101, and a plurality of splicing modules 100 are spliced ​​into the shell 10 through the splicing portion 101. During splicing, the shell 10 is made by splicing and forming a plurality of small modules, and the splicing portions 101 of adjacent splicing modules 100 can be adaptively matched and then spliced ​​together. The adaptive matching of the splicing portions 101 of adjacent splicing modules 100 can be a snap-on connection or a threaded connection, which is not limited by the embodiment of the utility model.

[0058] In this embodiment, the material of the splicing module 100 can be any insulating material such as plastic, rubber, carbon fiber, etc., and can be manufactured by any process such as injection molding, machining, etc. In this embodiment, injection molding is used as an example.

[0059] In this embodiment, refer to Figure 3 The plurality of splicing modules 100 include a first type module 110 , and the first type module 110 is further provided with a component mounting structure 111 for mounting components.

[0060] When installing components, the circuit of the components can be connected to the circuit outside the housing through the through hole connected to the installation hole, so as to achieve electrical connection of the components. The installation structure 111 can be a threaded structure or a buckle structure, which is not limited in the embodiment of the utility model. A variety of components can be installed on the first type module 110, such as relays, fuses, etc.

[0061] In this embodiment, the first type module 110 is manufactured by injection molding. Since the structure of the first type module 110 is simple, multiple first type modules 110 with the same specifications can be obtained by a simple mold, thereby reducing production costs. Since the first type module 110 is produced by mold injection molding, the mounting structure 111 set on the first type module 110 also has the same specifications. Accordingly, the various components installed, such as relays, fuses, etc., are correspondingly designed to adapt to the connection parts of the mounting structure 111, and the connection parts of various components are standardized, thereby ensuring the stable connection and standardization of the components.

[0062] In this embodiment, the shell 10 includes a plurality of splicing modules 100, each splicing module 100 is provided with a splicing portion 101, and a plurality of splicing modules 100 are spliced ​​together through the splicing portion 101 to form the shell 10; since the splicing modules 100 are similar to building blocks, and the shapes of these splicing modules 100 are relatively uniform, the production of the splicing modules 100 does not require complex molds or complex production lines. Each splicing module 100 can be produced using a simple mold due to its simple structure, which is more cost-effective, more precise, and more efficient in design; and the splicing modules 100 are more standardized. When the shell 10 is produced, compared with the shells with complex molds injection molded in the prior art, the shells 10 made of multiple splicing modules 100 use less materials, avoid complex mold opening, and further reduce production costs. At the same time, the splicing modules 100 with a higher degree of standardization can set up an automated splicing production line in the actual production process for manufacturing the shell 10, thereby further improving production efficiency.

[0063] In some embodiments, optionally, reference Figure 7, the multiple splicing modules 100 also include a second type module 120, the second type module 120 includes a first connection part 121 and a second connection part 122; the first connection part 121 and the second connection part 122 are fixedly connected at their ends, and an angle α is formed between a first center line 1211 of the first connection part 121 and a second center line 1221 of the second connection part 122, the angle α can be an acute angle, a right angle, or an obtuse angle, and those skilled in the art can select it according to actual needs, and the embodiment of the utility model does not limit it. The second type module 120 is used for splicing at the corner position of the housing 10, and similar to the first type module 110, based on the injection molding production process, multiple second type modules 120 also have the same specifications and shapes.

[0064] Optionally, an angle α between a first center line 1211 of the first connection portion 121 and a second center line 1221 of the second connection portion 122 is 90°.

[0065] Specifically, refer to Figure 7 and Figure 1 When the housing 10 is assembled, if it is necessary to assemble into a closed or semi-closed housing 10, a transition surface needs to be formed, such as Figure 1 As shown in , the corner position 11 is the position where two different planes of the shell intersect, and the second type module 120 can be used to assemble the corner position 11 of the shell 10, the first center line 1211 of the first connecting part 121 and the second center line 1221 of the second connecting part 122 are perpendicular to each other, and the first connecting part 121 and the second connecting part 122 are respectively used as different planes of the corner. This improves the flexibility of the shell 10 during assembly, and facilitates assembly into a cabin to accommodate components.

[0066] Optionally, a fifth type of module may also be included, and the fifth type of module is arranged in a structure with three sides intersecting vertically, such as Figure 1 As shown in , when the shell 10 is spliced, the fifth type module is spliced ​​at the vertex position 12 of the shell 10, and the vertex position 12 of the shell 10 is the position where three different planes of the shell intersect vertically. The fifth type module with a three-surface vertically intersecting structure can further improve the flexibility of the shell 10 assembly and the sealing performance of the shell 10 after splicing.

[0067] Optionally, refer to Figure 8 The splicing module 100 further includes a third type module 130 , which is used for splicing at a position other than the first type module 110 and the second type module 120 in the housing 10 .

[0068] Specifically, Figure 8A third type module 130 is specifically shown. Similar to the first type module 110, based on the production process of injection molding, multiple third type modules 130 also have the same specifications and shapes. When the shell 10 is spliced, the third type module 130 is used to splice the positions other than the first type module 110 and the second type module 120 in the shell 10, further improving the flexibility of the shell 10 assembly. Compared with the first type module 110, the third type module 130 has a simpler structure, does not require processing and installation structure, and is simpler to produce, thereby saving production costs.

[0069] The shell splicing process is briefly described below. One splicing method is: according to the number and position requirements of component installation, multiple first-type modules 110 are spliced ​​together to obtain a shell 10, and components are installed on the mounting structure 111 of the first-type module 110 at preset positions to complete the shell splicing. Adjacent components are spaced a certain distance apart to achieve electrical isolation between the components.

[0070] One splicing method is: according to the number and position requirements of component installation, multiple first type modules 110 and third type modules 130 are spliced ​​together to obtain a shell 10, and components are installed on the mounting structure 111 of the first type module 110 at preset positions to complete the shell splicing.

[0071] One splicing method is: first, according to the number and position requirements of component installation, multiple first-type modules 110 and third-type modules 130 are spliced ​​to complete the construction of the bottom of the shell 10, and then the components are installed on the mounting structure 111 of the first-type module 110, and then according to the assembly space and assembly environment, the second-type module 120 is spliced ​​at the transfer position of the shell 10, and then according to the height requirements of the components, the required splicing modules 100 are continued to be spliced ​​to complete the overall shell side construction, and then multiple first-type modules 110 and third-type modules 130 are used to splice to complete the construction of the top of the shell 10, and finally the components are installed and protected. The shell 10 spliced ​​by the splicing modules 100 made of insulating materials electrically isolates the components from the internal components of the battery pack.

[0072] One splicing method is: when the shell 10 is spliced, first, according to the number and position requirements of component installation, multiple first-type modules 110 and third-type modules 130 are spliced ​​to complete the construction of the bottom of the shell 10, and then the components are installed on the mounting structure 111 of the first-type module 110, and then according to the assembly space and assembly environment, the second-type module 120 is spliced ​​at the transfer position of the shell 10, and then according to the height requirements of the components, the required splicing modules 100 are continued to be spliced ​​to complete the construction of the side of the overall shell, and finally the components are installed. Similarly, the shell 10 spliced ​​by the splicing modules 100 made of insulating materials electrically isolates the components from the internal components of the battery pack.

[0073] The above-mentioned splicing methods are only exemplary, and the specific splicing methods are not exclusive. In the case where the shell 10 is required to be sealed, a sealant can be applied to the splicing seam after the outer side of the shell 10 is spliced ​​to improve the overall sealing of the shell 10.

[0074] Optionally, the splicing module 100 also includes other types of modules, and the specific structures of other types of modules can be designed according to actual needs to meet the needs of components with functions such as bracket extension and gap shielding when assembling the shell.

[0075] In this embodiment, the corner position of the shell 10 can be formed by splicing the second type module 120. While increasing the flexibility of splicing the shell 10, when the shell 10 splices the faces that need to intersect, the second type module 120 can be used to more conveniently achieve it. The side of the shell 10 spliced ​​by the second type module 120 can provide certain protection for the components installed in the shell. At the same time, the third type module 130 can fill the redundant position when the shell 10 is spliced. During design and assembly, considering the final assembly space of the shell 10 and the different internal components, the flexibility of splicing the shell 10 can be improved by the third type module 130. According to different assembly spaces, different numbers and types of splicing modules 100 are selected for shell splicing. In addition, the third type module 130 can increase the distance between the components installed on the adjacent first type module 110, thereby improving the safety between the components.

[0076] In some embodiments, optionally, reference Figure 5 and Figure 6 The splicing portion 101 is a snap-fit ​​structure, which is arranged on the side of the splicing module 100 , and a plurality of splicing modules 100 are spliced ​​together to form the housing 10 through the snap-fit ​​structure.

[0077] Specifically, Figure 5 Specifically shows a card connection structure, such as Figure 5As shown, the lower part of the splicing module is a cube, and the snap-in structure is set on the four sides of the splicing module 100. Two adjacent sides are set to form a C-matching structure in the snap-in structure, and the other two opposite sides are set to form a D-matching structure in the corresponding snap-in structure. Alternatively, the two opposite sides can be set to form a C-matching structure in the snap-in structure, and the other two sides can be set to form a D-matching structure in the corresponding snap-in structure. The embodiment of the utility model does not limit this. The adjacent splicing modules 100 can achieve a stable connection after splicing through the snap-in structure, and can also be quickly disassembled when disassembly is required.

[0078] Optionally, refer to Figure 6 The snap-fitting structure is a pin 102 and / or a pin hole 103 provided on the side of the splicing module 100 ; wherein the pin 102 of one splicing module 100 is snap-fitted with the pin hole 103 of the adjacent splicing module 100 .

[0079] Specifically, Figure 6 Specifically shows a card connection structure, such as Figure 6 As shown, the snap-fit ​​structure is a relatively matched pin 102 and pin hole 103. When splicing, the pin 102 can be correspondingly snapped into the pin hole 103 of the adjacent splicing module 100, thereby realizing the connection of multiple splicing modules 100. And when the housing 10 needs to be disassembled to repair the internal components, the matching of the pin 102 and the pin hole 103 can also be quickly removed, which is convenient for repairing the components. The following are three exemplary snap-fit ​​methods:

[0080] 1. Some splicing modules 100 only have pins 102, and another splicing module 100 only has pin holes 103. When splicing, the splicing module 100 with only pins 102 is placed at the center, and the other splicing modules 100 with only pin holes 103 are clamped from four directions, and so on, to complete the splicing of the shell 10.

[0081] Second, each splicing module 100 has a pin 102 and a pin hole 103, such as Figure 1 In the splicing form, the pin 102 of one splicing module 100 is snap-fitted into the pin hole 103 of the adjacent splicing module 100, and so on, to complete the splicing of the shell 10.

[0082] 3. Some splicing modules 100 have pins 102 and pin holes 103 on their sides, some splicing modules 100 have only pins 102 on their sides, and some splicing modules 100 have only pin holes 103 on their sides. When connecting, the splicing module 100 with only pin holes or the splicing module with only pins is placed at the center position, and then different splicing modules are selected according to the form of the pins and pin holes, and so on to complete the splicing of the shell 10.

[0083] Optionally, refer to Figure 4The pin 102 includes a connecting shaft 1021 and a clamping shaft 1022. The diameter of the connecting shaft 1021 is smaller than the diameter of the clamping shaft 1022. One end of the connecting shaft 1021 is connected to the clamping shaft 1022, and the other end of the connecting shaft 1021 is connected to the side of the splicing module 100. At least one protrusion 1023 is provided at one end of the clamping shaft 1022 close to the connecting shaft 1021.

[0084] Specifically, Figure 4 Specifically, a pin 102 is shown, which includes a connecting shaft 1021 and a clamping shaft 1022. One end of the connecting shaft 1021 is connected to the clamping shaft 1022, and the other end is connected to the side of the splicing module 100. The clamping shaft 1022 is provided with at least one protrusion 1023 at one end close to the connecting shaft 1021. Therefore, when the pin 102 is clamped with the pin hole 103, the protrusion 1023 can be tightly abutted against the inner wall of the pin hole 103, thereby improving the bonding force between the splicing modules 100 and further improving the stability of the shell.

[0085] Optionally, a serrated mounting portion 1024 is provided at one end of the clamping shaft 1022 close to the connecting shaft 1021 , and a gap is provided between the mounting portion 1024 and the connecting shaft 1021 ; the protrusion 1023 is provided on a side of the mounting portion 1024 away from the connecting shaft.

[0086] Specifically, Figure 4 Specifically, a pin 102 is shown, such as Figure 4 As shown, the serrated mounting portion 1024 and the gap between the mounting portion 1024 and the connecting shaft 1021 make it easier to insert the protrusion 1023 into the pin hole 103 when the pin 102 is snapped into the pin hole 103, thereby reducing the difficulty of assembly.

[0087] Optionally, a groove may be provided on the pin 102, one end of the protrusion 1023 is connected to the pin 102, and the other end is separated from the pin 102 and partially accommodated in the groove, and the separated end of the protrusion 1023 can move along the axial direction of the vertical pin 102. When the pin 102 is inserted into the pin hole 103, the protrusion 1023 is squeezed and retracted into the groove, so that it is easier to clamp the pin. After the pin 102 is inserted into the pin hole 103, the protrusion 1023 accommodated in the groove can rebound and tightly abut against the inner wall of the pin hole 103, thereby increasing the combination strength of the pin 102 and the pin hole 103 and making it more convenient to disassemble. Of course, the specific structure of the protrusion can be selected according to actual design needs, and the embodiment of the utility model does not limit this.

[0088] In this embodiment, the splicing part 101 is a snap-fit ​​structure, which is arranged on the side of the splicing module 100, and multiple splicing modules 100 are spliced ​​into the housing 10 through the snap-fit ​​structure. Thereby, the stability of multiple splicing modules 100 is achieved when splicing, and they can be quickly disassembled when they need to be disassembled. The snap-fit ​​structure is specifically a pin 102 and / or a pin hole 103, and the pin 102 of a splicing module 100 is snap-fitted with the pin hole 103 of the adjacent splicing module 100. The structural form of the pin 102 and the pin hole 103 can meet the requirements of splicing stability while also being able to be quickly disassembled. The protrusion 1023 and the serrated mounting portion 1024 provided on the pin 102 and the gap between the mounting portion 1024 and the connecting shaft 1021 make it easier to insert the protrusion 1023 into the pin hole 103 when the pin 102 is snapped into the pin hole 103, thereby reducing the difficulty during assembly. The protrusion 1023 abuts against the inside of the pin hole 103, thereby increasing the bonding strength between the splicing modules 100 and further increasing the stability of the shell.

[0089] In some embodiments, optionally, reference Figure 5 The snap-fit ​​structure is a male buckle 104 and / or a female buckle 105 provided on the side of the splicing module 100 ; wherein the male buckle 104 of one splicing module 100 is snap-fitted with the female buckle 105 of an adjacent splicing module 100 .

[0090] Specifically, Figure 5 A snap-fit ​​structure is specifically shown. The snap-fit ​​structure is a snap-fit ​​structure. The male buckle 104 and the female buckle 105 are respectively arranged on different sides of the splicing module 100. A plurality of protrusions are arranged on the plane where the male buckle 104 intersects with the splicing module 100. When splicing, the male buckle 104 is snapped into the female buckle 105 of the adjacent splicing module 100, and the protrusion of the male buckle 104 is tightly abutted against the inner wall of the female buckle 105, thereby connecting the adjacent splicing modules 100 together. The embodiment of the utility model does not limit which side the male buckle 104 and the female buckle 105 arranged on different sides of the splicing module are specifically arranged on. The embodiment of the utility model does not limit the number and specific position of the protrusions on the male buckle 104.

[0091] Optionally, the outer surface of the male buckle 104 and the inner surface of the female buckle 105 can be provided with mutually matching inclined surfaces relative to each other for easy assembly. Of course, the specific structures of the male buckle 104 and the female buckle 105 can be selected according to actual design needs, and the embodiment of the utility model does not limit this.

[0092] In this embodiment, multiple splicing modules 100 can be connected together by means of a snap-on structure provided on different sides of the splicing module 100. While ensuring a stable connection between the multiple splicing modules 100, it is also convenient for the user to quickly disassemble the splicing module 100 when repairing components installed in the shell 10, thereby improving the disassemblyability of the shell 10.

[0093] In some embodiments, reference Fig. 9 and Fig.10 The clamping structure is a clamping hole 160 , which is arranged on the side of the splicing module 100 ; the shell also includes a clamping shaft 150 , and both ends of the clamping shaft 150 are respectively clamped in the clamping hole 160 of the adjacent splicing module 100 .

[0094] Specifically, Fig. 9 Specifically, a card shaft 150 is shown. Fig.10 Specifically, a clamping hole 160 is shown. When the housing 10 is spliced, the two ends of the clamping shaft 150 are respectively clamped in the clamping holes 160 of the adjacent splicing modules 100, thereby realizing the connection of multiple splicing modules 100. When disassembly is required, the splicing modules 100 can also be quickly removed. The clamping shaft 150 can be a conventional circular shaft, or movable bosses can be set on the cylindrical surfaces at both ends of the conventional circular shaft, and the bosses can be movable in a direction perpendicular to the axis of the circular shaft, thereby facilitating installation and improving the bonding force of the splicing modules 100. The specific structure of the clamping shaft 150 can be selected according to actual design needs, and the embodiment of the utility model does not limit this.

[0095] In this embodiment, multiple splicing modules 100 can be connected together by snapping the clamping shaft 150 into the clamping hole 160 of the splicing module 100. The clamping shaft 150 independent of the splicing module 100 makes it more flexible and convenient when splicing the housing 10, thus improving the flexibility of the operation.

[0096] In some embodiments, reference Figure 3 , Figure 6 and Figure 7 The splicing module 100 includes: a bottom plate 106 and a boss 107 , the boss 107 is arranged on the bottom plate 106 , and the orthographic projection of the boss 107 on the surface of the bottom plate 106 is within the surface of the bottom plate; the splicing part 101 is arranged on the side of the bottom plate 106 .

[0097] Specifically, Figure 3 Specifically, a splicing module 100 is shown, which includes: a bottom plate 106 and a boss 107, wherein the boss 107 is arranged on the bottom plate 106, and the orthographic projection of the boss 107 on the surface of the bottom plate 106 is within the surface of the bottom plate 106; and a splicing portion 101 is arranged on the side of the bottom plate 106. Thus, when the modules are spliced, it is more convenient for production personnel or automated equipment in the production line to clamp them.

[0098] Optionally, the thickness of the boss 107 of the first type module 110 is greater than the thickness of the boss 107 of the splicing modules 100 other than the first type module 110 among the plurality of splicing modules 100 .

[0099] Specifically, refer to Figure 1 Considering that components need to be installed on the first type module 110, the thickness of the boss arranged on the first type module 110 is greater than the thickness of the boss of other splicing modules 100 (such as the second type module 120 and the third type module 130), so that there is enough space on the first type module 110 to set the installation structure 111, thereby ensuring the stability of the components after installation.

[0100] In this embodiment, the splicing module 100 optionally includes a bottom plate 106 and a boss 107, and the orthographic projection of the boss 107 on the bottom plate 106 is within the surface of the bottom plate 106. Figure 3 , the width of the boss 107 in the horizontal direction is smaller than the width of the bottom plate 106 in the horizontal direction, and the splicing part 101 is arranged on the side of the bottom plate 106. Therefore, when the modules are spliced, it is more convenient for the production personnel or the automation equipment in the production line to clamp. At the same time, the thickness of the boss arranged on the first type module 110 is greater than the thickness of the boss of other splicing modules 100, so that there is enough space on the first type module 110 to arrange the installation structure 111, thereby ensuring the stability of the components after installation.

[0101] In some embodiments, optionally, reference Figure 8 The housing 10 further includes an isolation module 140 , which is detachably connected to at least one joint seam. The joint seam is a gap formed between two adjacent bosses 107 after two adjacent joint modules 100 are joined.

[0102] Specifically, refer to Figure 8 and Figure 1 When installing components, the components may need to be isolated from each other, or the components may need to be shielded in the vertical or horizontal direction. The thickness of the isolation module 140 is set to be smaller than the thickness of the splicing seam, and then the isolation module 140 is arranged in the splicing seam of the splicing module 100, so that the components can be shielded in different directions. For example, adjacent components are electrically isolated from each other by the isolation module 140 arranged therebetween. When the isolation module 140 is connected to the splicing module 100 at the splicing point, it can be a fixed connection such as bonding, or a detachable connection such as snap-on. The specific connection method of the isolation module 140 is not limited by the embodiment of the utility model. The isolation module 140 can also provide a certain degree of support for the side or top surface of the shell 10.

[0103] Optionally, refer to Figure 8 The isolation module 140 includes an isolation module body 141 and a clamping structure 142 , wherein the clamping structure 142 is disposed at a first end 143 of the isolation module body 141 ; after the first end 143 of the isolation module body 141 is inserted into the joint, the clamping structure 142 is clamped against the boss 107 .

[0104] Specifically, the first end 143 of the isolation module body 141 is provided with a tightening structure 142. After the first end 143 of the isolation module body 141 is inserted into the joint, the tightening structure 142 is pressed against the boss 107. At this time, the width of the tightening structure 142 is greater than the groove width formed by the bosses 107 of the two adjacent splicing modules 100, so that stable installation can be performed, thereby improving the installation stability of the isolation module 140. Of course, the thrust of the tightening structure 142 on the boss 107 after it is unfolded is much smaller than the bonding force between the splicing parts 101.

[0105] Optionally, refer to Figure 8 The pressing structure 142 is a spring sheet, which is connected to the isolation module body 141 to form an opening facing the first end 143 .

[0106] Specifically, refer to Figure 8 The abutting structure 142 is a spring sheet, which is connected to the isolation module body 141 to form an opening facing the first end 143. When installing the abutting structure 142, the production personnel or the automated equipment of the production line can first compress the spring sheet to reduce the width of the opening, and then insert the abutting structure 142 into the joint seam, and the spring sheet will automatically pop open and abut against the adjacent boss 107. While improving the assemblability of the isolation module 140, the stability after assembly is also improved.

[0107] Optionally, abutment structures 142 are provided on both sides of the first end 143 of the isolation module body 141 .

[0108] for example Figure 8 In the embodiment, two abutting structures 142 are connected to the isolation module body 141. In this way, after the isolation module 140 is inserted into the joint, the abutting structures 142 on both sides abut against the bosses 107 on both sides respectively, so that the isolation module is more firmly connected.

[0109] Optionally, one end of the boss 107 close to the bottom plate 106 is an inclined surface, and the inclined surface and the bottom plate form a slot; after the first end 143 of the isolation module body 141 is inserted into the joint, the abutting structure 142 is embedded in the slot.

[0110] Specifically, the first end 143 of the isolation module body 141 is provided with abutting structures 142 on both sides, so that when the isolation module 140 is installed, the balance and stability of the left and right sides of the isolation module 140 can be ensured; and the end of the boss 107 close to the bottom plate 106 is an inclined surface, and the inclined surface and the bottom plate form a slot; after the first end 143 of the isolation module body 141 is inserted into the joint, the buttressing structure 142 is embedded in the slot. The above-formed slot can make the isolation module 140 easier to assemble, and the cooperation between the formed slot and the buttressing structure 142 can further improve the assembly stability of the isolation module 140.

[0111] In this embodiment, by providing an isolation module 140, the components installed inside the housing 10 can be isolated to improve the safety of the components. At the same time, the tightening structure 142 provided at the bottom of the isolation module 140 can further improve the stability of the installation of the isolation module 140. The boss 107 on the splicing module 100 is an inclined surface at one end close to the bottom plate 106, and the inclined surface and the bottom plate form a slot, which is more conducive to the installation of the isolation module 140 and improves the flexibility of assembly. At the same time, the isolation module 140 installed at the splicing of the splicing module 100 can also block the splicing gap and improve the sealing of the housing. The isolation module 140 can also provide a certain degree of support for the side or top surface of the housing 10.
