[0003] In view of this, the present invention provides a splicing battery pack and a battery pack assembly device to reduce battery pack assembly time and improve production efficiency.

[0004] In a first aspect, this utility model provides a modular battery pack having a three-dimensional shape with intersecting first, second, and third directions, comprising:

[0005] The first housing includes a first base plate and a first frame; wherein the first frame surrounds the circumferential edge of the first base plate and has a height away from the first base plate in a third direction;

[0006] The first frame has a first side beam extending along a second direction, and the first side beam is spaced apart on both sides of the first box body along the first direction.

[0007] The second housing is independently and separable from the first housing; the second housing includes a second base plate and a second frame; wherein the second frame surrounds the circumferential edge of the second base plate and has a height in a third direction away from the second base plate;

[0008] The second frame has a second side beam extending along a second direction, and the second side beam is spaced apart on both sides of the second box along a first direction.

[0009] The first guide groove extends along the second direction and is located at the end of the first side beam;

[0010] A guide member extends along a second direction and is located at the end of the second side beam; the guide member is disposed opposite to the first guide groove, and the guide member is adapted to be spliced ​​with the first guide groove to fix the first box and the second box.

[0011] Beneficial effects: The modular battery pack provided by this utility model allows for the quicker and more convenient replacement and installation of the second and first housings and their internal components by independently and separably setting the second housing and the first housing. During the battery pack assembly process, it is only necessary to push the second housing to move linearly along the second direction Y towards the direction closer to the first housing, and insert the guide member into the first guide groove. Thus, through the guiding effect of the guide member and the first guide groove, the assembly benchmark verification time of the second housing and the first housing is greatly shortened, reducing time consumption and improving the battery pack assembly efficiency.

[0012] In one alternative embodiment, the first side beam further includes a locking component, which includes an elastic reset member located within a first guide groove; the guide member has a locking groove on its side; the locking component is adapted to engage with the locking groove.

[0013] The locking component engages with the locking groove in the first state and disengages from the locking groove in the second state.

[0014] Beneficial effects: During the assembly process, under the guidance of the guide and the first guide groove, when the second housing moves into position relative to the first housing along the second direction Y, the locking component and the locking groove are just engaged, and the guide is just inserted into the first guide groove, so that the second side beam is locked with the first side beam, thereby connecting the second housing and the first housing to form an integral battery pack.

[0015] In one optional embodiment, the guide member has a first guide portion at one end near the first guide groove along the second direction, wherein the first guide portion has a first guide slope, and the first guide slope is arranged along the insertion direction of the guide member and the first guide groove.

[0016] Beneficial effects: By setting a first guide part with a first guide slope, the guide part can continuously self-correct with the first guide groove during the docking and guiding process. This is achieved through the interaction between the inner wall of the first guide part and the first guide groove, until they are completely aligned. This ensures a certain error tolerance during the docking and guiding stage and provides accurate guidance for the subsequent insertion and assembly of the connector.

[0017] In one alternative implementation, the first guide groove includes a first groove and a second groove that are independently disposed of with respect to each other;

[0018] Each guide component includes a first guide rod and a second guide rod that are independently configured.

[0019] The first guide rod is adapted to be inserted into the first groove along the second direction, and the second guide rod is adapted to be inserted into the second groove along the second direction.

[0020] Beneficial effects: By setting independent first and second guide rods, during the docking and insertion process between the guide member and the first guide groove, the first guide rod is inserted into the first groove, and the second guide rod is inserted into the second groove. This simultaneously restricts the sliding direction of the second housing relative to the first housing in the first direction X and the third direction Z, while ensuring the connection strength between the second side beam and the first side beam, thus improving the structural stability of the entire battery pack.

[0021] In one alternative embodiment, the first housing further includes a first connector electrically connected to the electrical module; the second housing further includes a second connector electrically connected to the battery cell module; the first connector and the second connector are arranged opposite to each other along a second direction, and the first connector is adapted to be plugged into and electrically connected to the second connector.

[0022] Beneficial effects: Through the docking and guidance of the guide component and its first guide part with the first guide groove, the second connector and the first connector can be accurately and quickly plugged in and matched, thereby realizing the electrical connection between the first box and the second box, and thus the first box and the second box can be combined to form a complete battery pack, improving the connection efficiency and operational safety of the first box and the second box.

[0023] In one alternative embodiment, the first connector is provided with a second guide groove;

[0024] The second connector is provided with a second guide portion, which extends along a second direction and protrudes outward;

[0025] The second guide portion is adapted to be inserted into the second guide groove along the second direction, wherein the second guide portion has a second guide slope, and the second guide slope is arranged along the insertion direction of the first connector and the second connector.

[0026] Beneficial effects: Through the guide component and the docking of its first guide part with the first guide groove, the second connector and the first connector can be accurately and quickly inserted and matched. When the second connector is about to be inserted into the second guide groove, the docking of the second guide part with the second guide groove ensures that the second connector and the first connector are accurately and quickly inserted and matched, thereby further improving connection efficiency and operational safety, and thus ensuring the stability and safety of the entire battery pack.

[0027] In one optional embodiment, the modular battery pack further includes a buffer element, which is attached between the first housing and the second housing, and the buffer element is an elastic reset element.

[0028] The buffer has a clearance opening along the second direction, which is suitable for avoiding the first connector and the second connector.

[0029] Beneficial effects: Avoids rigid contact between the third and fourth side beams, preventing damage to the first and second connectors.

[0030] Secondly, this utility model also provides a battery pack assembly device, suitable for assembling the above-mentioned spliced ​​battery pack, the battery pack assembly device including assembly fixtures.

[0031] Assembly fixtures include connecting brackets and rollers;

[0032] The connecting bracket includes a bracket plate and a guide rail extending along a second direction. The bracket plate is arranged parallel to and opposite to the first base plate and the second base plate along a third direction.

[0033] The guide rail is suitable for guiding the first and second side beams to move linearly along the second direction;

[0034] Multiple rollers are rolled on the guide rail, and the rollers are adapted to rollly connect with the first side beam and the second side beam.

[0035] Beneficial effects: By setting up assembly fixtures and guiding the first and second side beams to move linearly along the second direction Y via guide rails, the guide component aligns with the first guide groove along the second direction Y, thereby further guiding the second connector to engage with the first connector. The alignment of the second guide component with the second guide groove ensures precise and rapid engagement between the second and first connectors. After the locking component engages with the locking groove, the second housing and the first housing are connected to form a single battery pack. The entire battery pack is then pushed along the guide rails to the designated sliding assembly structure position on the vehicle, allowing the first and second side beams to engage with the designated sliding assembly structure. During this process, the rollers prevent scratches and wear on the battery pack, ensuring the overall stability of the battery pack structure. The assembly fixtures are then removed, and finally, the entire battery pack is fixed to the designated sliding assembly structure on the vehicle. This significantly shortens the assembly benchmark verification time, reduces time consumption, and improves battery pack assembly efficiency and safety.

[0036] In one alternative embodiment, the guide rail includes a third guide ramp extending along a second direction and a mounting plate; the third guide ramp is angled to the bracket plate.

[0037] Beneficial effects: This prevents the second and first housings from deviating from the guide rail, ensuring the accuracy and stability of the sliding direction of the second and first housings.

[0038] In one optional embodiment, the mounting plate is fixedly disposed on the third guide slope, and the mounting plates are respectively disposed on both sides of the roller along the axial direction, with the roller and the mounting plate being rotatably connected.

[0039] Beneficial effects: The rollers are rotatably connected to the mounting plate, thus preventing scratches and wear on the battery pack and ensuring the overall stability of the battery pack structure. Attached Figure Description

[0066] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0067] The following is combined Figures 1 to 17 The following describes embodiments of the present invention.

[0068] According to an embodiment of the present invention, in one aspect, a modular battery pack is provided, having a three-dimensional shape with intersecting first direction X, second direction Y, and third direction Z, comprising:

[0069] The first housing 10 includes a first base plate 11 and a first frame 12; wherein the first frame 12 surrounds the circumferential edge of the first base plate 11 and has a height away from the first base plate 11 in a third direction Z.

[0070] The first frame 12 has a first side beam 121 extending along the second direction Y, and the first side beam 121 is spaced apart on both sides of the first box 10 along the first direction X;

[0071] The second housing 20 is independently and separable from the first housing 10; the second housing 20 includes a second base plate 21 and a second frame 22; wherein the second frame 22 surrounds the circumferential edge of the second base plate 21 and has a height along the third direction Z away from the second base plate 21.

[0072] The second frame 22 has a second side beam 221 extending along the second direction Y, and the second side beam 221 is spaced apart on both sides of the second box 20 along the first direction X;

[0073] The first guide groove 1210 extends along the second direction Y and is located at the end of the first side beam 121;

[0074] Guide member 23 extends along the second direction Y and is located at the end of the second side beam 221; guide member 23 is disposed opposite to the first guide groove 1210, and guide member 23 is adapted to be spliced ​​with the first guide groove 1210 to fix the first box 10 and the second box 20.

[0075] The first base plate 11 and the first frame 12 enclose a first cavity 100, which serves as an electrical compartment, and the electrical module 30 is disposed within the first cavity 100; the second base plate 21 and the second frame 22 enclose a second cavity 200, which serves as a battery cell compartment, and the battery cell module 40 is disposed within the second cavity 200.

[0076] The modular battery pack provided by this utility model allows for the quicker and more convenient replacement and installation of the second housing 20 and the first housing 10, as well as their internal components, by independently and separably setting the second housing 20 and the first housing 10. During the battery pack assembly process, it is only necessary to push the second housing 20 to move linearly along the second direction Y toward the direction closer to the first housing 10, and insert the guide member 23 into the first guide groove 1210. Through the guiding effect of the guide member 23 and the first guide groove 1210, the assembly benchmark verification time of the second housing 20 and the first housing 10 is greatly shortened, reducing time consumption and improving the battery pack assembly efficiency.

[0077] Furthermore, the guide member 23 can be fixed to the second side beam 221 by welding or adhesive.

[0078] Furthermore, the end of the guide member 23 away from the first side beam 121 along the second direction Y can be inserted into the cavity (not shown) of the second side beam 221, and then the guide member 23 is welded and fixed to the second side beam 221.

[0079] In some embodiments, see Figure 9 As shown, the first side beam 121 also includes a locking component 122, which includes an elastic reset member located within the first guide groove 1210; please refer to Figure 12 As shown, the guide member 23 has a locking groove 2301 on its side; the locking member 122 is adapted to engage with the locking groove 2301.

[0080] The locking member 122 has a first state parallel to the second direction Y, and a second state folded and deviated from the second direction Y under the action of external force; the locking member 122 engages with the locking groove 2301 in the first state, and disengages from the locking groove 2301 in the second state.

[0081] During the assembly process, under the guidance of the guide member 23 and the first guide groove 1210, when the second housing 20 moves into position relative to the first housing 10 along the second direction Y, the locking member 122 and the locking groove 2301 are just engaged, and the guide member 23 is just inserted into the first guide groove 1210 so that the second side beam 221 is locked with the first side beam 121, thereby connecting the second housing 20 and the first housing 10 to form an integral battery pack.

[0082] When the battery pack needs to be reassembled, simply pull the locking component 122 away from the locking groove 2301 and disengage the guide component 23 from the first guide groove 1210. At this time, the locking component 122 will return to the first state under its own elastic restoring force.

[0083] Furthermore, the locking component 122 can be a sheet metal part, and the locking component 122 is welded to the first side beam 121.

[0084] In some embodiments, see Figure 12 As shown, the guide member 23 is provided with a first guide portion 2302 at one end near the first guide groove 1210 along the second direction Y. The first guide portion 2302 has a first guide slope, which is arranged along the insertion direction of the guide member 23 and the first guide groove 1210.

[0085] By providing a first guide portion 2302 with a first guide slope, the guide member 23 can continuously self-correct with the first guide portion 2302 and the inner wall of the first guide groove 1210 during the docking and guiding process. This interaction between the guide member 23 and the first guide groove 1210 ensures that the guide member 23 and the first guide groove 1210 are fully aligned, thus guaranteeing a certain error tolerance during the docking and guiding stage and providing accurate guidance for the next step of connector mating.

[0086] In some embodiments, see Figure 9 As shown, the first guide groove 1210 includes a first groove 1211 and a second groove 1212 that are independently arranged.

[0087] Please see Figure 12 As shown, the guide member 23 includes a first guide rod 231 and a second guide rod 232 that are independently arranged, and both the first guide rod 231 and the second guide rod 232 extend along the second direction Y;

[0088] The first guide rod 231 is adapted to be inserted into the first groove 1211 along the second direction Y, and the second guide rod 232 is adapted to be inserted into the second groove 1212 along the second direction Y.

[0089] By setting independent first guide rods 231 and second guide rods 232, during the docking and insertion process of the guide member 23 and the first guide groove 1210, the first guide rod 231 is inserted into the first groove 1211, and the second guide rod 232 is inserted into the second groove 1212. This simultaneously restricts the sliding direction of the second housing 20 relative to the first housing 10 in the first direction X and the third direction Z, while ensuring the connection strength between the second side beam 221 and the first side beam 121, thereby improving the structural stability of the entire battery pack.

[0090] Furthermore, the cross-sections of both the first guide rod 231 and the second guide rod 232 are triangular.

[0091] Furthermore, the locking groove 2301 is formed on the side of the first guide rod 231 away from the second guide rod 232 along the first direction X.

[0092] In some embodiments, see Figure 8 As shown, the first frame 12 has a third side beam 123 extending along the first direction X, and the third side beam 123 is disposed on the side of the first box 10 close to the second box 20 along the second direction Y.

[0093] Please see Figure 11 As shown, the second frame 22 has a fourth side beam 222 extending along the first direction X. The fourth side beam 222 is located on the side of the second box 20 close to the first box 10 along the second direction Y. The third side beam 123 is arranged opposite to the fourth side beam 222 along the second direction Y.

[0094] See also Figure 8 As shown, the first housing 10 also includes a first connector 13, which is disposed within the third side beam 123 along the second direction Y, and is electrically connected to the electrical module 30; see also Figure 11 As shown, the second housing 20 also includes a second connector 24, which is disposed in the fourth side beam 222 along the second direction Y. The second connector 24 is electrically connected to the battery module 40. The first connector 13 and the second connector 24 are disposed opposite to each other along the second direction Y. The first connector 13 is adapted to be plugged into and electrically connected to the second connector 24.

[0095] Through the docking and guidance of the guide member 23 and its first guide part 2302 with the first guide groove 1210, the second connector 24 and the first connector 13 are accurately and quickly plugged in and matched, thereby realizing the electrical connection between the first housing 10 and the second housing 20, and thus the first housing 10 and the second housing 20 are combined to form a complete battery pack, improving the connection efficiency and operational safety of the first housing 10 and the second housing 20.

[0096] In some embodiments, see Figure 10 As shown, the first connector 13 is provided with a second guide groove 131. The second guide groove 131 is recessed in the third side beam 123 along the second direction Y, and the opening of the second guide groove 131 is exposed on the side of the third side beam 123 facing the fourth side beam 222 along the second direction Y.

[0097] Please see Figure 13 As shown, the second connector 24 is provided with a second guide portion 241, which extends along the second direction Y and protrudes from the side of the fourth side beam 222 facing the third side beam 123 along the second direction Y.

[0098] The second guide portion 241 is adapted to be inserted into the second guide groove 131 along the second direction Y, wherein the second guide portion 241 has a second guide slope, which is arranged along the insertion direction of the first connector 13 and the second connector 24.

[0099] Through the docking and guidance of the guide member 23 and its first guide part 2302 with the first guide groove 1210, the second connector 24 and the first connector 13 are accurately and quickly inserted and matched. When the second connector 24 is about to be inserted into the second guide groove 131, the docking and guidance of the second guide part 241 with the second guide groove 131 ensures that the second connector 24 and the first connector 13 are accurately and quickly inserted and matched, thereby further improving the connection efficiency and operational safety, and thus ensuring the stability and safety of the entire battery pack.

[0100] In some embodiments, see Figure 16 As shown, the modular battery pack also includes a buffer 50, which is attached between the first housing 10 and the second housing 20. The buffer 50 is an elastic reset component.

[0101] Please see below. Figure 17 As shown, the buffer 50 has a clearance opening 500 along the second direction Y, which is suitable for clearing the first connector 13 and the second connector 24.

[0102] By providing a buffer 50 between the third side beam 123 and the fourth side beam 222, rigid contact between the third side beam 123 and the fourth side beam 222 is avoided, thus preventing damage to the first connector 13 and the second connector 24.

[0103] Furthermore, the cushioning element 50 can be cushioning foam.

[0104] During the assembly process, when the second housing 20 moves into position relative to the first housing 10 along the second direction Y, the buffer 50 is just compressed, the locking component 122 and the locking groove 2301 are just locked together, and at the same time the second connector 24 and the first connector 13 are inserted into position. At this time, the second housing 20 and the first housing 10 are connected to form an integral battery pack.

[0105] According to embodiments of this utility model, on the other hand, please combine with... Figures 1-3 As shown, a battery pack assembly apparatus is also provided, suitable for assembling the above-mentioned modular battery pack. The battery pack assembly apparatus includes an assembly fixture 60.

[0106] Please see Figure 14 As shown, the assembly fixture 60 includes a connecting bracket 61 and rollers 62;

[0107] Please see Figure 15As shown, the connecting bracket 61 includes a bracket plate 611 and two guide rails 612 extending along the second direction Y. The bracket plate 611 is arranged parallel to and opposite to the first base plate 11 and the second base plate 21 along the third direction Z.

[0108] Two guide rails 612 are respectively provided on both sides of the support plate 611 along the first direction X. The guide rails 612 are adapted to guide the first side beam 121 and the second side beam 221 to move linearly along the second direction Y.

[0109] Each guide rail 612 is provided with multiple rollers 62, which are adapted to be rolledly connected with the first side beam 121 and the second side beam 221.

[0110] By setting up the assembly fixture 60 and guiding the first side beam 121 and the second side beam 221 to move linearly along the second direction Y via the guide rail 612, the guide member 23 is guided to align with the first guide groove 1210 along the second direction Y, thereby further guiding the second connector 24 to engage with the first connector 13. The alignment of the second guide part 241 with the second guide groove 131 ensures precise and rapid engagement between the second connector 24 and the first connector 13. After the locking member 122 engages with the locking groove 2301, the second housing 20 and the first housing 10 are connected. The battery pack is assembled into a whole. At this time, the whole battery pack is pushed along the guide rail 612 to the designated sliding assembly structure position of the vehicle, so that the first side beam 121 and the second side beam 221 are engaged with the designated sliding assembly structure of the vehicle. During this period, the roller 62 can prevent scratches and wear on the battery pack by rolling, ensuring the stability of the overall structure of the battery pack. Then the assembly fixture 60 is removed, and finally the whole battery pack is fixed with the designated sliding assembly structure of the vehicle. This greatly shortens the assembly benchmark verification time, reduces time consumption, and improves the battery pack assembly efficiency and safety.

[0111] Please see Figure 6 As shown, the first side beam 121 has a first inclined surface 1213 extending along the second direction Y, and the first inclined surface 1213 is set at an angle to the first base plate 11; please refer to Figure 7 As shown, the second side beam 221 has a second inclined surface 2211 extending along the second direction Y, and the second inclined surface 2211 is set at an angle to the second base plate 21.

[0112] In some embodiments, the guide rail 612 includes a third guide ramp 6121 extending along a second direction Y and two mounting plates 6122; the third guide ramp 6121 is angled to the bracket plate 611.

[0113] The third guide slope 6121 is set at an angle to the support plate 611, so that the guide rail 612 forms an inward angle. The guide rail 612 cooperates with the first slope 1213 and the second slope 2211 to prevent the second box 20 and the first box 10 from deviating from the guide rail 612, thus ensuring the accuracy and stability of the sliding direction of the second box 20 and the first box 10.
