Description

Technical Field

[0001] This utility model relates to the field of battery technology, and more specifically, to a battery pack. Background Technology

[0002] In traditional battery pack designs, metal end plates, batteries, and straps or side plates are typically assembled into modules before being fixed into the battery pack. This approach requires pre-assembling modules at the production end, with each module serving as a component in the overall pack assembly. This method necessitates individual module processing, requiring dedicated production lines for module assembly. Furthermore, the manufactured modules need to be transferred to the battery pack production line. Automation of processes such as end plate stacking, strapping, module turnover, and module placement within the pack is challenging, significantly increasing labor costs. Current technology increasingly employs CTP (cell-to-pack) technology to replace traditional module solutions, directly securing the battery pack between mounting beams within the battery pack. However, this approach requires squeezing the battery pack into the pack's receiving cavity, presenting challenges for battery pack placement within the pack.

[0003] Therefore, existing technologies present the problem of difficulty in fitting battery packs into the battery box. Utility Model Content

[0004] The main objective of this invention is to provide a battery pack that solves the problem of difficulty in installing battery packs in the existing technology.

[0005] To achieve the above objectives, according to one aspect of the present invention, a battery pack is provided, comprising: a housing assembly having a receiving cavity, wherein at least two mounting beams are spaced apart along a first direction within the receiving cavity; at least one battery pack, wherein at least one battery pack is located between two adjacent mounting beams, and the mounting beams and the battery packs having mutually cooperating guide structures on their adjacent sides to guide the battery packs as they enter the receiving cavity.

[0006] Furthermore, the guide structure includes a second guide ramp and a third guide ramp that cooperate with each other. In the third direction, the end of the mounting beam away from the bottom surface of the housing assembly has the second guide ramp, and the end of the battery pack near the bottom surface of the housing assembly has the third guide ramp, and the first direction and the third direction are perpendicular to each other.

[0007] Furthermore, a clearance groove is provided on the side of the mounting beam near the battery pack, and the clearance groove in the third direction is provided at one end of the mounting beam near the bottom surface of the housing assembly, and the first direction and the third direction are perpendicular to each other.

[0008] Furthermore, the battery pack includes: two insulating plates, which are spaced apart along a first direction; and a plurality of batteries, which are arranged along the first direction and disposed between the two insulating plates.

[0009] Furthermore, the insulating plate and the mounting beam have a mutually cooperating guide structure.

[0010] Furthermore, the battery pack also includes a slider, and at least one slider is provided on the outer surface of the housing assembly, the slider being used to guide the battery pack during its insertion into the cluster rack.

[0011] Furthermore, there are at least two sliders. At least one slider is provided on each of the two side beams of the housing assembly that are arranged opposite each other along the second direction, and the first direction and the second direction are perpendicular to each other.

[0012] Furthermore, at least one slider is provided at each end of the side beam in the first direction.

[0013] Furthermore, the number of sliders on the two side beams is equal and they are set in a mirror image.

[0014] Furthermore, the thickness direction of the slider is parallel to the second direction, and the slider includes a guide section and a sliding section arranged along the first direction. The guide section has a first guide slope on the side away from the side beam of the housing assembly, and the thickness of the guide section gradually increases along the direction close to the sliding section; and / or the sliding section has at least one mounting groove, and at least one connector is provided in the mounting groove. The slider is detachably connected to the housing assembly through the connector.

[0015] Applying the technical solution of this utility model, the battery pack in this application includes a housing assembly and at least one battery pack. The housing assembly has a receiving cavity, and at least two mounting beams are spaced apart along a first direction within the receiving cavity; at least one battery pack is located between two adjacent mounting beams, and the sides of the mounting beams and battery packs that are close to each other have mutually cooperating guide structures to guide the battery packs as they enter the receiving cavity.

[0016] During the assembly of the battery pack in this application, since the housing assembly has at least two mounting beams, when multiple battery packs need to be placed inside the battery pack, adjacent battery packs can be separated by adjusting the number of mounting beams. Alternatively, two adjacent battery packs along the first direction can be separated by mounting beams. Furthermore, mounting beams can also be provided at both ends of the housing assembly in the first direction to limit the movement of the battery packs. Simultaneously, during the process of assembling the battery pack into the housing, the mounting beams and the side of the battery pack that are close to each other have a cooperating guide structure, ensuring that the battery pack can be more easily installed into the housing to complete the assembly of the battery pack and the housing assembly. This reduces the difficulty of entering the housing and effectively improves the assembly efficiency of the battery pack. Therefore, the battery pack in this application effectively solves the problem of difficult battery pack installation in the prior art. Attached Figure Description

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0032] To address the problem of difficulty in installing battery packs into the battery box in the prior art, this application provides a battery pack.

[0033] like Figures 1 to 9 As shown, the battery pack in this application includes a housing assembly 10 and at least one battery pack 20. The housing assembly 10 has a receiving cavity 13, within which at least two mounting beams 14 are spaced apart along a first direction; at least one battery pack 20 is located between two adjacent mounting beams 14, and the sides of the mounting beams 14 and the battery pack 20 that are close to each other have mutually cooperating guide structures 40 to guide the battery pack 20 as it enters the receiving cavity 13. The mounting beams 14 can be crossbeams, longitudinal beams, or side beams in the housing, used to compress and limit the battery pack 20.

[0034] During the assembly of the battery pack in this application, since the receiving cavity 13 of the housing assembly 10 has at least two mounting beams 14, when multiple battery packs 20 need to be placed in the battery pack, adjacent battery packs 20 can be separated by adjusting the number of mounting beams 14. Alternatively, two adjacent battery packs 20 in the first direction can be separated by mounting beams 14. Furthermore, mounting beams 14 can also be provided at both ends of the housing assembly 10 in the first direction to limit the movement of the battery packs 20. Simultaneously, during the process of inserting the battery packs 20 into the receiving cavity 13, since the mounting beams 14 and the battery packs 20 have mutually cooperating guide structures 40 on their adjacent sides, the battery packs 20 can be more easily inserted into the receiving cavity 13 to complete the assembly of the battery packs 20 with the housing assembly 10, thereby reducing the difficulty of the battery packs 20 entering the receiving cavity 13 and effectively improving the assembly efficiency of the battery pack. Therefore, the battery pack in this application effectively solves the problem of difficult battery pack insertion in the prior art.

[0035] And, as Figure 1 As shown, in this application, the first direction generally refers to the X-axis direction, that is, the length direction of the housing assembly 10. The second direction generally refers to the Y-axis direction, that is, the width direction of the housing assembly 10. The third direction generally refers to the Z-axis direction, that is, the height direction of the housing assembly 10, and the housing assembly 10 is provided with a top surface and a bottom surface in this direction. Therefore, in this application, the first direction, the second direction, and the third direction are perpendicular to each other. At the same time, the housing assembly 10 in this application may include a lower housing 11 and a top cover 12. The lower housing 11 has a receiving cavity 13, and the top of the lower housing 11 has an opening in the Z-axis direction. The top cover 12 covers the lower housing 11 to form the top surface of the housing assembly 10.

[0036] In this application, by setting up a cluster rack 60 inside the container and using the cluster rack 60 to hold the battery pack, the space inside the container can be effectively utilized. The specific structure of the cluster rack 60 is prior art and will not be described in detail in this application.

[0037] Optionally, the guide structure 40 includes a second guide ramp 41 and a third guide ramp 42 that cooperate with each other. In the third direction, the end of the mounting beam 14 away from the bottom surface of the housing assembly 10 has the second guide ramp 41, and the end of the battery pack 20 near the bottom surface of the housing assembly 10 has the third guide ramp 42, and the first direction and the third direction are perpendicular to each other. During the battery pack assembly process, the cooperation of the second guide ramp 41 and the third guide ramp 42 makes it easier for the battery pack 20 to enter the receiving cavity 13.

[0038] Optionally, a clearance groove 141 is provided on the side of the mounting beam 14 near the battery pack 20, and the clearance groove 141 is located at one end of the mounting beam 14 near the bottom surface of the housing assembly 10. Since the battery pack usually also has a bottom cold plate, welding is required between the mounting beam 14 of the battery pack and the bottom cold plate on the inner bottom surface of the housing assembly 10. By providing a clearance groove 141 on the mounting beam 14, clearance space can be reserved for the weld scar between the mounting beam 14 and the bottom cold plate, thereby preventing interference between the battery pack 20 and the weld scar, and thus ensuring the performance of the battery.

[0039] Specifically, the battery pack 20 includes two insulating plates 21 and a plurality of batteries 22. The two insulating plates 21 are spaced apart along a first direction, and the insulating plates 21 and the mounting beam 14 have a mutually cooperating guide structure 40; the plurality of batteries 22 are arranged along the first direction and disposed between the two insulating plates 21. This arrangement can effectively improve the safety performance of the battery pack 20. Furthermore, in this application, the insulating plates 21 are made of insulating material.

[0040] Specifically, the battery pack also includes a module sampling component 50. In the third direction, the module sampling component 50 is positioned on the side of the battery pack 20 facing the top cover 12 of the housing assembly 10. The output terminal of the module sampling component 50 extends towards the bottom surface of the housing assembly 10, and the first direction and the third direction are perpendicular to each other. This arrangement effectively avoids the problem of increased overall battery pack height caused by the upward positioning of the output terminal of the module sampling component 50, thus facilitating the miniaturization design of the battery pack.

[0041] Optionally, the battery pack also includes a slider 30. At least one slider 30 is provided on the outer surface of the housing assembly 10, and the slider 30 serves as a guide during the process of placing the battery pack into the cluster rack. Because the battery pack in this application also has at least one slider 30, during the process of placing the assembled battery pack into the cluster rack 60 of the container, the cooperation between the slider 30 and the cluster rack 60 allows the battery pack to be placed more easily and accurately on the cluster rack 60, thereby effectively reducing labor costs.

[0042] Optionally, there are at least two sliders 30, with at least one slider 30 provided on each of a set of opposing side beams of the housing assembly 10. This arrangement allows the two side beams of the housing assembly 10 with sliders 30 to correspond to the two edges of the cluster rack 60, making it easier to place the battery pack on the cluster rack 60. Simultaneously, this arrangement ensures more even force distribution on the battery pack during placement into the cluster rack 60, guaranteeing that the battery pack is placed in the predetermined position on the cluster rack 60, thus enabling efficient use of the space within the container.

[0043] Specifically, the thickness direction of the slider 30 is parallel to the second direction. The slider 30 includes a guide section 31 and a sliding section 32 arranged along the first direction. The guide section 31 has a first guide slope 311 on the side away from the side beam of the housing assembly 10, and the thickness of the guide section 31 gradually increases along the direction close to the sliding section 32. Meanwhile, the sliding section 32 has at least one mounting groove, and at least one connector is provided in the mounting groove. The slider 30 is detachably connected to the housing assembly 10 through the connector. That is, in this application, the two side beams of the housing assembly 10 can be positioned and guided by the guide section 31 of the slider 30 and the two sides of the cluster frame 60, so that the two side beams of the housing assembly 10 can be aligned with the two sides of the cluster frame 60. Regarding the shape of the guide section 31, the guide section 31 can be wedge-shaped, and the side of the guide section 31 that fits against the housing assembly 10 is flat, while the side of the guide section 31 away from the side beam of the housing assembly 10 is sloped. Simultaneously, the thickness of the guide section 31 gradually decreases along the direction away from the sliding section 32 in the first direction. During the process of packing the battery into the cluster holder 60, the guide section 31 of the same slider 30 contacts the frame of the cluster holder 60 before the sliding section 32, so as to be positioned by the inclined surface of the guide section 31. Furthermore, in this application, the connector can be a bolt or a screw.

[0044] Preferably, the number of sliders 30 on the two side beams is equal and they are arranged in a mirror image. This arrangement further ensures more stable force distribution on the battery pack. Therefore, for the guide sections 31 of all sliders 30 on the housing assembly 10, the end with the lower thickness of the guide section 31 is oriented towards the direction of entering the cluster frame 60.

[0045] Specifically, at least one slider 30 is provided on each of the two side beams of the housing assembly 10 that are arranged opposite each other along the second direction. That is, when the battery pack is placed on the cluster rack 60, the battery pack slides into the cluster rack 60 along the first direction.

[0046] Optionally, at least one slider 30 is provided at each end of the side beam in the first direction. Of course, the installation position of the slider 30 can be adjusted adaptively according to the actual usage. Alternatively, the direction in which the battery pack slides into the cluster 60 can be determined according to the arrangement of the slider 30.

[0047] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0048] 1. Effectively solves the problem of difficulty in installing battery packs into the box in existing technologies;

[0049] 2. Simple structure and stable performance.
