[0032] An embodiment of the present invention provides a module 1000, which includes a plurality of battery cells 200 and a plurality of module positioning structures 100. The plurality of battery cells 200 are respectively assembled in a plurality of module positioning structures 100. The plurality of battery cells 200 and the plurality of module positioning structures 100 correspond one to one. The plurality of battery cells 200 can be electrically connected in series or in parallel or in series and parallel. The battery cells 200 can be lithium batteries, sodium batteries, lead-acid batteries, etc. The battery cells 200 are used to store and release electricity. A plurality of positioning shell assemblies 10 are arranged along the thickness direction thereof. The pins 21 in the module positioning structures 100 are inserted into the first positioning holes 102 of adjacent module positioning structures 100 to limit the connection of the plurality of module positioning structures 100 together. The pins 21 are used to limit the radial movement of the positioning shell assembly 10 along the first positioning holes 102.

[0033] Specifically, the module positioning structure 100 includes a positioning shell assembly 10 and a limiting assembly 20. The positioning shell assembly 10 is provided with a first battery compartment 101 and a first positioning hole 102. The first positioning hole 102 extends along the thickness direction of the positioning shell assembly 10. The position of the first positioning hole 102 can be at any position on the positioning shell assembly 10. The latch 21 is inserted into the first positioning hole 102 along the thickness direction of the positioning shell assembly 10, thereby limiting the movement of the adjacent positioning shell assembly 10 along its width or height direction. The first battery compartment 101 is used to place the battery cell 200. The battery cell 200 is assembled in the first battery compartment 101, and the battery cell 200 is limited by the positioning shell assembly 10. The limiting assembly 20 is connected to the positioning shell assembly 10, and the connection method can be screw connection, welding, or bonding. The limiting assembly 20 includes a latch 21, which is used to be inserted into the first positioning hole 102 of the adjacent positioning shell assembly 10.

[0034] In this embodiment, the first battery compartment 101 of the positioning shell assembly 10 can be equipped with a battery cell 200, thereby connecting the battery cell 200 and the positioning shell assembly 10 together, and the positioning shell assembly 10 is provided with a first positioning hole 102 along its thickness direction, and multiple positioning shell assemblies 10 are arranged and stacked together along their thickness direction, and the limiting assembly 20 and the positioning shell assembly 10 are connected together, and the pin 21 is inserted into the first positioning hole 102 of the adjacent positioning shell assembly 10, so that the pin 21 limits the radial movement of the positioning shell assembly 10 along the first positioning hole 102, that is, the pin 21 limits the movement of the positioning shell assembly 10 along the width direction, height direction and the direction between the width direction and the height direction of the positioning shell assembly 10, and multiple limiting assemblies 20 can limit the connection of multiple positioning shell assemblies 10 with battery cells 200 into a whole. The advantage of this arrangement is that the module positioning structure 100 assists in positioning the battery cell 200 when it is assembled, and compared with the existing module 1000, the overall strength is higher. In addition, using a standardized positioning shell assembly 10 to install the battery cell 200 can also avoid interference with the surface flatness of the battery cell 200.

[0035] In another embodiment of the present invention, the module 1000 further includes a tail shell assembly 300, an end plate 400 and a tie 500. A plurality of positioning shell assemblies 10 are stacked together in the thickness direction to form a whole, the tail shell assembly 300 is arranged at the end of the plurality of positioning shell assemblies 10, and the end plates 400 are respectively arranged at the side of the tail shell assembly 300 away from the positioning shell assembly 10 and at the head end of the plurality of positioning shell assemblies 10, that is, the end plates 400 are located at both ends of the module 1000, and the tie 500 bundles the end plates 400, the positioning shell assembly 10 and the tail shell assembly 300, and the tie 500 bundles the end plates 400, the positioning shell assembly 10 and the tail shell assembly 300 together to form a complete whole. The tie 500 can be a steel belt or a plastic belt.

[0036] The tail shell assembly 300 is provided with a second battery compartment 310 and a second positioning hole 320. The second positioning hole 320 extends along the thickness direction of the tail shell assembly 300. The battery cell 200 is assembled in the second battery compartment 310. The pin 21 of the limiting assembly 20 located at the end is inserted into the second positioning hole 320. Because the tail shell assembly 300 is located at the end of multiple positioning shell assemblies 10, in principle, the limiting assembly 20 does not need to be installed.

[0037] In order to enable those skilled in the art to have a further understanding of the present solution, the assembly process of the module 1000 will be explained in detail below, but it is worth noting that this does not impose any limitation on the technical solution of the present invention.

[0038] 1. Assemble multiple battery cells 200 in the first battery compartment 101 of the positioning shell assembly 10 and the second battery compartment 310 of the tail shell assembly 300 respectively; 2. Assemble the limiting assembly 20 on the positioning shell assembly 10; 3. Arrange and stack multiple limiting assemblies 20 along their thickness direction, and insert the pins 21 into the first positioning holes 102 of the adjacent positioning shell assemblies 10 and the second positioning holes 320 of the tail shell assembly 300 at the same time; 4. Place the end plate 400 on the side of the tail shell assembly 300 away from the positioning shell assembly 10 and the head ends of multiple positioning shell assemblies 10, and then use the strap 500 to bundle the end plate 400, the positioning shell assembly 10 and the tail shell assembly 300 together.

[0039] In this embodiment, the first battery compartment 101 of the positioning shell assembly 10 can be equipped with the battery cell 200, thereby connecting the battery cell 200 and the positioning shell assembly 10 together, and the second battery compartment 310 of the tail shell assembly 300 can be equipped with the battery cell 200, thereby connecting the battery cell 200 and the tail shell assembly 300 together. The positioning shell assembly 10 is provided with a first positioning hole 102 along its thickness direction, and the tail shell assembly 300 is provided with a second positioning hole 320 along its thickness direction. Multiple positioning shell assemblies 10 are arranged and stacked together along their thickness direction, and the tail shell assembly 300 is arranged at the end of multiple positioning shell assemblies 10, limiting the assembly 20 and the positioning shell assembly 10 to be connected together. The pin 21 is inserted into the first positioning hole 102 of the adjacent positioning shell assembly 10 and the second positioning hole 320 of the tail shell assembly 300, so that the pin 21 limits the radial movement of the positioning shell assembly 10 along the first positioning hole 102 and the pin 21 limits the radial movement of the tail shell assembly 300 along the second positioning hole 320. A plurality of limiting assemblies 20 can limit and connect a plurality of positioning shell assemblies 10 equipped with battery cells 200 and a tail shell assembly 300 equipped with battery cells 200 into a whole. The advantage of such a setting is that the module positioning structure 100 assists in positioning when the battery cells 200 are assembled, and it is convenient for the end plate 400 and the strap 500 to bundle the module 1000 into a whole. Compared with the current module 1000, the overall strength is higher. In addition, the use of a standardized positioning shell assembly 10 to install the battery cells 200 can also avoid interference with the surface flatness of the battery cells 200.

[0040] Continue reading Figure 3 and Figure 4The positioning shell assembly 10 includes an upper shell 12 and a lower shell 14 connected to each other. The upper shell 12 is provided with a first battery compartment 101. The lower shell 14 is connected to one end of the upper shell 12 away from the opening of the first battery compartment 101. The opening of the first battery compartment 101 and the lower shell 14 are distributed at opposite ends of the upper shell 12. The lower shell 14 is provided with a first positioning hole 102. The limiting assembly 20 is connected to the lower shell 14. In this embodiment, the first positioning hole 102 is provided at one end of the positioning shell assembly 10 away from the opening of the first battery compartment 101. The limiting assembly 20 is connected to one end of the positioning shell assembly 10 away from the opening of the first battery compartment 101, so that the limiting assembly 20 is assembled away from the battery cell 200 during the assembly process, and the limiting assembly 20 will not touch the battery cell 200, thereby avoiding unnecessary damage to the battery cell 200. In addition, during the normal assembly process of the module 1000, the upper shell 12 is at the top and the lower shell 14 is at the bottom, so the limiting assembly 20 is connected to the lower shell 14, so that the overall stability of the bottom of the module 1000 can be ensured.

[0041] Optionally, the upper shell 12 and the lower shell 14 can be made separately to reduce the difficulty of making the positioning shell assembly 10, and then welded, bonded or screwed together; the upper shell 12 and the lower shell 14 can also be integrally injection molded or integrally die-casted to improve the manufacturing efficiency of the positioning shell assembly 10.

[0042] The lower shell 14 is provided with a limiting groove 16, and the first positioning hole 102 is connected to the limiting groove 16. The limiting component 20 is accommodated in the limiting groove 16 and then inserted into the first positioning hole 102 of the adjacent positioning shell component 10. The limiting groove 16 can have an opening on one side, two sides, or three sides, which is not limited here. After the module 1000 is assembled, the limiting component 20 is accommodated in the limiting groove 16, and the limiting component 20 does not exceed the limiting groove 16, thereby preventing the limiting component 20 from interfering with other parts of the module 1000. In addition, the limiting groove 16 can also limit the position of the limiting component 20, which facilitates the assembly and connection of the limiting component 20 and the positioning shell component 10 to improve the assembly efficiency.

[0043] The number of the limiting grooves 16 is at least two, and at least two limiting grooves 16 are spaced apart along the width direction of the positioning shell assembly 10. Figure 4 As described above, the number of the limiting grooves 16 is two, and the two limiting grooves 16 are arranged at opposite ends of the lower shell 14 along the width direction of the positioning shell assembly 10. Of course, the number of the limiting grooves 16 can also be three, four, etc. The number of the limiting components 20 is at least two, and at least two limiting components 20 are respectively arranged in the limiting grooves 16. According to the number of the limiting grooves 16, a corresponding number of limiting components 20 is set. It can be understood that the more the number of limiting components 20, the higher the stability of the connection of the positioning shell assembly 10, thereby further improving the overall strength of the module 1000.

[0044] The diameter of the first positioning hole 102 is D1 mm, the diameter of the end of the plug pin 21 for inserting into the first positioning hole 102 is D2 mm, 0.2≤D1-D2≤0.4, for example, 0.2, 0.25, 0.3, 0.35, 0.4, etc. Within this range, it can be ensured that the plug pin 21 can be smoothly inserted into the first positioning hole 102, and the plug pin 21 will not shake significantly relative to the first positioning hole 102.

[0045] See also Figures 5 to 10 , and also assist in checking Figures 1 to 4 , Figure 6 is a schematic cross-sectional structural diagram of a limiting component 20 provided in an embodiment of the present invention in a first state, Figure 7 is a schematic diagram of the exploded structure of the limiting component 20 provided in an embodiment of the present invention in a first state, Figure 8 is a schematic diagram of the assembly structure of the limiting component 20 provided in an embodiment of the present invention in the second state, Fig. 9 is a schematic cross-sectional structural diagram of the limiting component 20 provided in an embodiment of the present invention in the second state, Fig.10 2 is a schematic diagram of the exploded structure of the limiting component 20 provided in an embodiment of the present invention in the second state.

[0046] In one embodiment, the limiting assembly 20 further includes a fixing block 22, a limiting pin 23 and an elastic reset member 24. The latch 21 is sandwiched between the fixing block 22 and the positioning shell assembly 10. The fixing block 22 is provided with a first slot 221. The latch 21 is inserted into the first slot 221 to enter the first positioning hole 102. The latch 21 can slide relative to the first slot 221. The limiting pin 23 is connected to the latch 21 and is located in the first slot 221. The limiting pin 23 is used to limit the latch 21 to prevent the latch 21 from being separated from the first slot 221. The elastic reset member 24 is arranged between the limiting pin 23 and the slot wall of the first slot 221. The elastic reset member 24 is used to provide elastic force so that the limiting pin 23 can abut against the slot wall of the first slot 221. At this time, the limiting assembly 20 is in the first state, and the length of the latch 21 extending from the first slot 221 to the first positioning hole 102 is the longest. The elastic reset member 24 can be a spring, an elastic sheet, or elastic silicone.

[0047] Under normal circumstances, during the assembly process, the pin 21 is pulled in the direction away from the first positioning hole 102 of the adjacent positioning shell assembly 10. At this time, the limiting pin 23 and the groove wall of the first groove 221 are separated, and the elastic return member 24 is in a deformed state (it can be a compressed state or a stretched state). The pin 21 is aligned with the first positioning hole 102 of the adjacent positioning shell assembly 10, and the pin 21 is released. Under the action of the elastic return member 24, the pin 21 moves toward the first positioning hole 102 of the adjacent positioning shell assembly 10 until the limiting pin 23 abuts against the groove wall of the first groove 221. At this time, the pin 21 is inserted into the first positioning hole 102 of the adjacent positioning shell assembly 10.

[0048] In another embodiment, the limiting component 20 includes a base 26, a fixed block 22, a limiting pin 23 and an elastic reset member 24. The difference between this embodiment and the previous embodiment is that the base 26 is added, the base 26 is connected to the positioning shell component 10, the latch 21 is clamped between the fixed block 22 and the base 26, and the elastic reset member 24 is arranged between the limiting pin 23 and the groove wall of the first groove 221. The difference between this embodiment and the previous embodiment is that the latch 21, the limiting pin 23 and the elastic reset member 24 are first assembled between the base 26 and the fixed block 22 to form a complete whole, and then assembled into the positioning shell component 10, so as to avoid the limiting component 20 occupying the module 1000 for too long during the assembly process, so as to achieve the purpose of modular production.

[0049] Furthermore, the limiting assembly 20 further includes a limiting plate 27 and a cover plate 28, the limiting plate 27 is assembled in the first groove 221, the elastic reset member 24 is arranged between the limiting pin 23 and the limiting plate 27, and the cover plate 28 is connected to the fixing block 22 and covers the first groove 221. This embodiment is different from the previous embodiment in that the limiting plate 27 replaces the groove wall of the first groove 221 to connect with the elastic reset member 24, the limiting plate 27 can adjust the tightness of the elastic reset member 24, and the cover plate 28 covers the first groove 221 to prevent other parts from entering the first groove 221 and affecting the normal contraction of the elastic reset member 24.

[0050] The limiting component 20 also includes a handle 25, which is connected to one end of the latch 21 near the first positioning hole 102, and the handle 25 is used for the user to hold. The fixing block 22 is provided with a second slot 223 and a rotating hole, and the latch 21 passes through the rotating hole and is inserted into the second slot 223. The second slot 223 is located at one end of the first slot 221 near the first positioning hole 102, and the second slot 223 is located between the first slot 221 and the first positioning hole 102. The handle 25 is assembled in the second slot 223, and the handle 25 can drive the latch 21 to rotate in the rotating hole so as to be completely accommodated in the second slot 223. The handle 25 abuts against the slot wall of the second slot 223. At this time, the limiting component 20 is in the second state.

[0051] Under normal circumstances, during the assembly process, after the handle 25 is rotated relative to the rotating hole by a preset angle, the handle 25 extends out from the second slot 223, and the user pushes the handle 25 to pull the pin 21 in the direction away from the first positioning hole 102 of the adjacent positioning shell assembly 10. At this time, the limiting pin 23 and the slot wall of the first slot 221 are separated, and the elastic reset member 24 is in a deformed state. The pin 21 is aligned with the first positioning hole 102 of the adjacent positioning shell assembly 10, and the pin 21 is released. Under the action of the elastic reset member 24, the pin 21 moves toward the first positioning hole 102 of the adjacent positioning shell assembly 10 until the limiting pin 23 abuts against the slot wall of the first slot 221. At this time, the pin 21 is inserted into the first positioning hole 102 of the adjacent positioning shell assembly 10. Similarly, all other limiting components 20 are installed according to this step, and then after the strap 500 has completed bundling the entire module 1000, the handle 25 is rotated in the opposite direction to the rotating hole by a preset angle, and the handle 25 is accommodated in the second groove 223. The handle 25 does not exceed the second groove 223, so that the handle 25 does not interfere with other parts of the module 1000.

[0052] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0053] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.

[0054] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
