[0022] The battery pack cabinet assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the battery pack cabinet assembly 100 according to an embodiment of the present utility model includes a cabinet 10 and a battery pack 20.

[0024] Specifically, in conjunction with the reference appendix Figure 1 Appendix Figure 2 and attached Figure 4As shown, the electrical cabinet 10 has a roller assembly 1, which includes a sub-roller assembly 11. The electrical cabinet 10 is positioned in the left-right direction (e.g., ...). Figure 2 Both inner walls of the shown) are provided with sub-roller assemblies 11, the sub-roller assemblies 11 including rollers along the front-back direction (e.g. Figure 4 As shown, multiple rollers 12 are spaced apart. The battery pack 20 is located inside the cabinet 10 and includes a body 6 and a guide rail 7. The body 6 has guide rails 7 on both sides in the left and right directions that cooperate with the sub-roller group 11. The guide rails 7 extend in the front and back direction, and the rollers 12 make rolling contact with the guide rails 7.

[0025] In a specific example, see Appendix Figure 4 As shown, the roller assembly 1 includes two sub-roller groups 11. A sub-roller group is provided on each of the two inner walls in the left and right directions of the electrical cabinet 10. The battery pack 20 has two guide rails 7, which are respectively located on both sides of the main body 6 in the left and right directions. The two guide rails 7 are respectively engaged with the two sub-roller groups 11.

[0026] It is understandable that the power cabinet 10 is used to store, manage and protect the battery pack 20. The battery pack 20 is located inside the power cabinet 10. The power cabinet 10 can provide physical protection for the battery pack 20 to prevent damage to the battery pack 20 from external impacts, dust, moisture and other environmental factors, and ensure that the battery pack 20 operates in a safe and stable environment.

[0027] Currently, the vast majority of energy storage battery products on the market are installed in cabinets by force-pushing and bolt fixing. The installation process is cumbersome, easily scratches the product surface, resulting in damage to the product's appearance and reduced weather resistance. Furthermore, because it requires a high level of physical strength from the installers, it can also easily cause personal injury.

[0028] The battery pack cabinet assembly 100 of this utility model has sub-roller groups 11 on the inner walls of the left and right sides of the cabinet 10. Each sub-roller group 11 includes multiple rollers 12 spaced apart in the front-back direction. The battery pack 20 body 6 has guide rails 7 on the left and right sides that cooperate with the sub-roller groups 11. The rollers 12 and guide rails 7 make rolling contact, which can convert the sliding friction in the prior art into rolling friction, greatly reducing the friction force when assembling the battery pack 20 and the cabinet 10. On the one hand, it is easier to install the battery pack 20 into the cabinet 10, reducing the assembly and maintenance difficulty of the battery pack 20, reducing the threat to the personal safety of the installers, and improving the safety during installation. On the other hand, it can avoid scratches on the surface of the battery pack 20 and the inner wall of the cabinet 10 during the installation of the battery pack 20, reduce the impact of the battery pack 20 on the appearance and weather resistance of the battery pack cabinet assembly 100 during the installation process, and improve the aesthetics and reliability of the battery pack cabinet assembly 100.

[0029] Furthermore, since each sub-roller assembly 11 includes multiple rollers 12 spaced apart in the front-to-back direction, it can support the guide rail 7 from multiple spaced points in the front-to-back direction, thereby improving the load-bearing capacity of the sub-roller assembly 11, ensuring the support strength of the sub-roller assembly 11 for the guide rail 7, further reducing the assembly difficulty during battery pack 20 installation, and improving the reliability of the battery pack 20 after assembly.

[0030] For example, each sub-roller group 11 can have two, three, or four rollers 12. See the attached diagram for a specific example. Figure 4 As shown, each sub-roller assembly 11 includes three rollers 12 spaced apart in the front-to-back direction, which can support the guide rail 7 from three spaced-apart points in the front-to-back direction, improve the load-bearing capacity of the sub-roller assembly 11, ensure the support strength of the sub-roller assembly 11 for the guide rail 7, further reduce the assembly difficulty during battery pack 20 installation, and improve the reliability of battery pack 20 after assembly.

[0031] Further, see Appendix Figure 1 and attached Figure 2 As shown, the cabinet 10 includes a cabinet body 101 and a cabinet door 102. The cabinet body 101 defines an accommodating space and is open at the front end. The battery pack 20 is detachably installed in the accommodating space. The cabinet door 102 is rotatably connected to the front end of the cabinet body 101 to open or close the open front end of the cabinet body 101. When the cabinet door 102 is open, it facilitates the disassembly and maintenance of the battery pack 20. When the cabinet door 102 is closed, it prevents external impacts, dust, moisture and other environmental factors from damaging the battery pack 20, ensuring that the battery pack 20 operates in a safe and stable environment.

[0032] Furthermore, see the attached document. Figure 1 As shown, ventilation holes 104 are provided on the side wall of the cabinet body 101. The ventilation holes 104 connect the storage space with the external environment and can be used for heat dissipation to ensure the stability of the temperature inside the cabinet 10 and improve the safety of the battery pack cabinet assembly 100.

[0033] According to the embodiment of the present invention, the battery pack cabinet assembly 100 has sub-roller groups 11 on the inner walls of the left and right sides of the cabinet 10. Each sub-roller group 11 includes multiple rollers 12 spaced apart in the front-back direction. The battery pack 20 body 6 has guide rails 7 on the left and right sides that cooperate with the sub-roller groups 11. The rollers 12 and guide rails 7 make rolling contact, which can convert the sliding friction in the prior art into rolling friction, greatly reducing the friction force when assembling the battery pack 20 and the cabinet 10. On the one hand, it is easier to install the battery pack 20 into the cabinet 10, reducing the assembly and maintenance difficulty of the battery pack 20, reducing the threat to the personal safety of the installers, and improving the safety during installation. On the other hand, it can avoid scratches on the surface of the battery pack 20 and the inner wall of the cabinet 10 during the installation of the battery pack 20, reduce the impact of the battery pack 20 installation process on the appearance and weather resistance of the battery pack cabinet assembly 100, and improve the aesthetics and reliability of the battery pack cabinet assembly 100. Furthermore, since each sub-roller assembly 11 includes multiple rollers 12 spaced apart in the front-to-back direction, it can support the guide rail 7 from multiple spaced points in the front-to-back direction, thereby improving the load-bearing capacity of the sub-roller assembly 11, ensuring the support strength of the sub-roller assembly 11 for the guide rail 7, further reducing the assembly difficulty during battery pack 20 installation, and improving the reliability of the battery pack 20 after assembly.

[0034] In some embodiments of this utility model, reference is made to the appendix. Figure 4 As shown, the roller 12 includes a connecting shaft 121 and a rolling element 122. The connecting shaft 121 is connected to the inner wall of the electrical cabinet 10 and extends in the left-right direction. The rolling element 122 is rotatably disposed at the end of the connecting shaft 121 away from the inner wall of the electrical cabinet 10. The rolling element 122 is located inside the guide rail 7 and rolls in contact with the guide rail 7. The rolling friction between the rolling element 122 and the guide rail 7 replaces the sliding friction, which significantly reduces the movement resistance and facilitates the installation of the battery pack 20 into the electrical cabinet 10. The connecting shaft 121 is used to support the rolling element 122, ensuring that the rolling element 122 is fixed to the inner wall of the electrical cabinet 10 and that the rolling element 122 can rotate.

[0035] In a further embodiment of this utility model, in conjunction with reference to the appendix... Figure 3 and attached Figure 5 As shown, the guide rail 7 includes a main body section 71, two mating sections 72, and two constraint sections 73. The main body section 71 is fixed to the body 6 and is vertically arranged. The two mating sections 72 are respectively connected to the main body section 71 in the vertical direction (e.g., ...). Figure 5 As shown, at both ends, the mating section 72 extends in the front-back direction, and the end of the mating section 72 away from the main body section 71 extends in the direction away from the main body 6. The two constraint sections 73 are respectively connected to the ends of the two mating sections 72 away from the main body section 71. The two constraint sections 73 extend in the direction close to each other and are spaced apart. The rolling element 122 is located between the two mating sections 72 and between the constraint section 73 and the main body section 71.

[0036] It is understood that the rolling element 122 is located between two mating sections 72, which can limit the rolling element 122 from the upper and lower sides respectively. The rolling element 122 is located between the constraint section 73 and the main body section 71, which can limit the rolling element 122 from the axial sides respectively. As a result, the guide rail 7 is roughly "C" shaped in cross-section perpendicular to the front and rear direction, which realizes the limitation of the rolling element 122 in the four directions of up, down, left and right. This ensures the relative movement between the rolling element 122 and the guide rail 7 in the front and rear direction, reduces the shaking of the rolling element 122 in the guide rail 7, prevents the rolling element 122 from falling out of the guide rail 7, ensures the support of the rolling element 122 for the guide rail 7, improves the mechanical strength of the battery pack 20 installation, and improves the stability and reliability of the battery pack cabinet assembly 100.

[0037] It should be noted that by spacing the two constraint segments 73 at their closest ends to each other, the connecting shaft 121 can pass through, ensuring that the rolling element 122 can enter the area defined by the guide rail 7, thus ensuring the normal support of the roller 12 for the guide rail 7.

[0038] In some embodiments of this utility model, reference is made to the appendix. Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the two inner walls of the electrical cabinet 10 in the left and right directions are provided with first limiting blocks 2. The first limiting blocks 2 are located at the front end of the electrical cabinet 10. The first limiting blocks 2 are fixed to the front end of the guide rail 7 by positioning pins 23. After the battery pack 20 is assembled into the electrical cabinet 10, the positioning pins 23 fix the first limiting blocks 2 to the front end of the guide rail 7, which can realize the positioning of the guide rail 7 in the front and back directions, preventing the battery pack 20 from sliding forward after assembly and preventing the battery pack 20 from accidentally sliding out of the electrical cabinet 10, thus ensuring the stability and reliability of the battery pack 20 installation. It should be noted that the fixing method of positioning pins 23 can reduce the use of professional installation tools such as electric screwdrivers and torque wrenches, making the connection operation between the guide rail 7 and the first limiting blocks 2 simple and convenient, and reducing the difficulty of installing and fixing the battery pack 20.

[0039] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 and attached Figure 5As shown, the first limiting block 2 includes an upper limiting block 21 and a lower limiting block 22. The upper limiting block 21 and the lower limiting block 22 are located on the upper and lower sides of the guide rail 7, respectively. The positioning pin 23 is sequentially inserted into the upper limiting block 21, the guide rail 7 and the lower limiting block 22. After the battery pack 20 is placed into the cabinet 10, the positioning pin 23 passes through the upper limiting block 21, the guide rail 7 and the lower limiting block 22 from top to bottom. This allows for the precise positioning and fixing of the upper limiting block 21, the guide rail 7 and the lower limiting block 22 using a single fastener. This reduces the number of parts in the battery pack cabinet assembly 100, simplifies the operation steps when fixing the battery pack 20, shortens the assembly time of the battery pack 20 and improves the assembly efficiency of the battery pack cabinet assembly 100.

[0040] In a specific example, see Appendix Figure 5 As shown, the positioning pin 23 includes a positioning rod 231 and a protrusion 232. The positioning rod 231 extends in the vertical direction, and the protrusion 232 is connected to the outer peripheral wall of the positioning rod 231 and located at the upper end of the positioning rod 231. There are two protrusions 232, which are located on opposite radial sides of the positioning rod 231. The upper limit block 21 has a first positioning hole 211, and the lower limit block 22 has a second positioning hole 221. The two mating sections 72 of the guide rail 7 are each provided with a third positioning hole 721. After the battery pack 20 is assembled, the first positioning hole 211, the second positioning hole 221, and the two third positioning holes 721 are arranged opposite each other in the vertical direction. The positioning pin 23 passes through the first positioning hole 211, the second positioning hole 221, and the two third positioning holes 721.

[0041] Further, see attached document. Figure 5 As shown, the first positioning hole 211 is located at the end of the upper limit block 21 that is away from the inner wall of the electrical cabinet 10. The end of the first positioning hole 211 facing the battery pack 20 is open. The protrusion 232 of the positioning pin 23 is located inside the first positioning hole 211. The shape of the first positioning hole 211 matches the upper end of the positioning pin 23, which can prevent the positioning pin 23 from rotating after assembly and ensure the reliability of the positioning pin 23.

[0042] In some embodiments of this utility model, reference is made to the appendix. Figure 4 As shown, load-bearing beams 3 are provided on the two inner walls of the electrical cabinet 10 in the left and right directions. The load-bearing beams 3 extend in the front and back directions. The rollers 12 are fixed on the load-bearing beams 3. The cooperation between the load-bearing beams 3 and the rollers 12 can improve the structural strength of the electrical cabinet 10, improve the mechanical strength of the installation of the guide rails 7 and the sub-roller group 11, and ensure the reliability and safety of the battery pack 20 installation.

[0043] In a specific example, see Appendix Figure 5As shown, the upper limit block 21 and the lower limit block 22 are both connected to the front end of the load-bearing beam 3. The upper limit block 21 and the lower limit block 22 are located on the upper and lower sides of the load-bearing beam 3 respectively and are arranged opposite to each other in the vertical direction. Multiple rollers 12 are welded and fixed on the load-bearing beam 3.

[0044] Optionally, refer to the appendix. Figure 2 As shown, the two inner walls of the electrical cabinet 10 in the left and right directions are provided with support beams 103. The support beams 103 extend in the vertical direction to enhance the structural strength of the cabinet body 101. There can be multiple support beams 103 arranged at intervals in the front and back directions. The load-bearing beams 3 can be fixed on the support beams 103 or directly fixed on the inner walls of the electrical cabinet 10 in the left and right directions.

[0045] In some embodiments of this utility model, reference is made to the appendix. Figure 4 As shown, a second limiting block 4 is provided on the rear inner wall of the electrical cabinet 10. There are two second limiting blocks 4, which are spaced apart in the left and right direction. The two second limiting blocks 4 abut against the two guide rails 7 respectively, and the second limiting blocks 4 are spaced apart from the body 6. It can be understood that since the rear end of the guide rail 7 is flush with the rear end of the body 6, the second limiting block 4 is provided on the rear inner wall of the electrical cabinet 10 to abut against the guide rail 7. This can indirectly separate the body 6 of the battery pack 20 from the rear inner wall of the electrical cabinet 10, leaving a certain gap at the rear of the body 6 of the battery pack 20. This avoids the rear end of the body 6 from colliding with the rear inner wall of the electrical cabinet 10 when the battery pack 20 is assembled into the electrical cabinet 10, thus avoiding damage to the battery pack 20 and the electrical cabinet 10. It also reduces the impact of the battery pack 20 installation process on the appearance and weather resistance of the battery pack cabinet assembly 100, and improves the aesthetics and reliability of the battery pack cabinet assembly 100.

[0046] Preferably, refer to the appendix Figure 4 As shown, the front surface of the second limiting block 4 is provided with a reinforcing protrusion 41. After the battery pack 20 is assembled, the reinforcing protrusion 41 and the guide rail 7 are arranged and spaced apart in the left and right directions. This can enhance the structural strength of the second limiting block 4 while avoiding affecting the normal installation of the battery pack 20 and preventing the distance between the battery pack 20 and the rear inner wall of the cabinet 10 from being too far, thus effectively utilizing the space inside the cabinet 10.

[0047] In a further embodiment of this utility model, reference is made to the appendix. Figure 4As shown, a rear crossbeam 5 is provided on the rear inner wall of the electrical cabinet 10. The rear crossbeam 5 extends in the left and right direction. Two second limiting blocks 4 are provided on the rear crossbeam 5 and are located at both ends of the rear crossbeam 5 in the left and right direction. The body 6 and the rear crossbeam 5 are arranged opposite to each other in the front and back direction and are spaced apart. The rear crossbeam 5 can improve the structural strength of the rear of the electrical cabinet 10. The two second limiting blocks 4 are fixed on the front surface of the rear crossbeam 5. When the rear end of the guide rail 7 abuts against the second limiting block 4, the body 6 and the rear crossbeam 5 are spaced apart in the front and back direction, which can leave a certain gap at the rear of the body 6 of the battery pack 20. This avoids the rear end of the body 6 from colliding with the rear crossbeam 5 when the battery pack 20 is assembled into the electrical cabinet 10, avoids damage to the battery pack 20 and the electrical cabinet 10, reduces the impact of the battery pack 20 installation process on the appearance and weather resistance of the battery pack cabinet assembly 100, and improves the aesthetics and reliability of the battery pack cabinet assembly 100.

[0048] Optionally, the rear plate crossbeam 5 and the two second limiting blocks 4 can be integrally machined or separately machined; no further restrictions are imposed here.

[0049] In some embodiments of this utility model, the number of rollers 12 in the sub-roller groups 11 on the two inner walls of the power cabinet 10 in the left and right directions is the same. Furthermore, in the left and right directions, the multiple rollers 12 in the sub-roller groups 11 on the two inner walls of the power cabinet 10 in the left and right directions are arranged one-to-one with each other. This can make the guide rails 7 on the left and right sides of the same battery pack 20 bear the force evenly, ensuring the overall left and right sides of the battery pack 20 bear the force evenly. This avoids abnormal situations such as the battery pack 20 being tilted due to insufficient support on the left or right side, and avoids the battery pack 20 becoming unstable after long-term use. This ensures the installation stability of the battery pack 20 and extends the service life of the battery pack cabinet assembly 100.

[0050] In some embodiments of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2 As shown, multiple battery packs 20 are spaced apart along the vertical direction, and multiple roller assemblies 1 correspond one-to-one with the multiple battery packs 20. This allows multiple battery packs 20 to be integrated into the same cabinet 10, facilitating unified monitoring and maintenance. Centralized management of the multiple battery packs 20 optimizes their charging and discharging strategies, extending their lifespan. For example, the battery packs 20 can be two, four, six, eight, ten, or twelve spaced apart along the vertical direction, and the roller assemblies 1 can be two, four, six, eight, ten, or twelve corresponding to each of the multiple battery packs 20.

[0051] Preferably, refer to the appendix Figure 1 and attached Figure 2As shown, multiple roller assemblies 1 are evenly distributed on the inner wall of the cabinet 10 along the vertical direction.
