DETAILED DESCRIPTION

[0034] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to various alternative embodiments as well. It is to be understood that the description of any exemplary embodiment is intended only to be used in conjunction with the accompanying drawings, and that each exemplary embodiment can be used independently of one another. The following description is intended only to apply to the exemplary embodiments as set out in the claims, and is not intended to be limited to the disclosed aspects.

[0035] Reference will now be made to Figure 1The battery pack according to the present disclosure exemplarily comprises a first shell 11, a partition beam 12, a power distribution box 2 and a fuse box 3 which are arranged in the first shell 11 respectively. The partition beam 12 can be a cross beam, a longitudinal beam or the like. The partition beam 12 can be used to improve the structural strength of the battery pack, or can also be used to group the battery modules of the battery pack, thereby enriching the functions of the battery pack. The fuse box 3 and the power distribution box 2 are located on the two sides of the partition beam 12, and the fuse box 3 and the power distribution box 2 are connected by a first connecting piece 41, that is, one end of the first connecting piece 41 is electrically connected with the fuse box 3, and the other end is electrically connected with the power distribution box 2. Here, "the fuse box 3 and the power distribution box 2 are located on the two sides of the partition beam 12" means that the partition beam 12 is located between the fuse box 3 and the power distribution box 2 to form a positional relationship of separating the two.

[0036] The power distribution box 2 refers to a battery disconnect unit (BDU) of the battery pack. As a device for disconnecting and connecting high-voltage electricity of the power battery, the power distribution box 2 is a working unit for high-voltage distribution, cutting and short-circuit protection of the battery system, and usually contains functions such as overcurrent protection design, overheat protection design, connection and cutting of high-voltage current, which plays a crucial role in the safety of the battery pack. The internal structure of the power distribution box 2 can be adaptively designed according to the needs, and the present disclosure does not limit it. It should be noted that the power distribution box 2 can also be provided with a fuse to form a current protection effect on the corresponding branch inside the power distribution box 2, which is installed at a different position from the fuse box 3 mentioned in the present disclosure, and the protected circuit is also different.

[0037] The fuse box 3 refers to a protection device provided with a fuse (i.e. a fuse) to automatically disconnect the circuit when the current is too large. Similarly, the present disclosure does not limit the specific structure thereof, which will be introduced below.

[0038] In the embodiments of the present disclosure, during actual assembly, the power distribution box 2 and the fuse box 3 can be installed in the first shell 11 respectively, and then electrically connected through the first connecting piece 41. In some other embodiments, the power distribution box 2 and the fuse box 3 can be electrically connected first and then installed in the first shell 11.

[0039] The present disclosure does not limit the first connecting piece 41, which can be a copper bar, an aluminum bar or the like, as long as it can realize the electrical connection relationship between the fuse box 3 and the power distribution box 2.

[0040] By using the above technical solution, the power distribution box 2 and the fuse box 3 are designed in a split type, and are located on the two sides of the partition beam 12 and are electrically connected through the first connecting piece 41, so that the protection function of the fuse box 3 can be ensured while avoiding the problem of installation interference with the partition beam 12 caused by integrating the fuse box 3 and other components of the power distribution box 2 in the traditional scheme, effectively solving the problems of space arrangement and assembly interference in the battery pack.

[0041] In the embodiments of the present disclosure, the first connecting member 41 can be arranged to pass through the partition beam 12 from the upper side of the partition beam 12 to connect the fuse box 3 and the distribution box 2, where the "upper side" refers to the side of the partition beam 12 close to the cover of the battery pack, that is, the first connecting member 41 can be arranged to pass through the gap between the partition beam 12 and the cover of the battery pack. It should be explained that the first shell 11 can include a tray and a cover arranged on the tray (i.e., the cover of the battery pack), and the battery module, the distribution box 2 and the fuse box 3 are all arranged in the tray and form a closed space through the cover. In use, the cover is arranged on the upper side of the tray, the fuse box 3, the distribution box 2 and the partition beam 12. In the following, the relevant orientation will be explained through the upper cover of the battery pack, and the concept of the cover of the battery pack and the positional relationship with other components will not be explained again. Further, in the embodiments of the present disclosure, the first connecting member 41 can be attached to the upper surface of the partition beam 12 (the surface close to the cover of the battery pack), or can have a gap with the upper surface of the partition beam 12. By arranging the first connecting member 41 to pass through the partition beam 12 from the upper side of the partition beam 12, a through hole is not needed to be arranged on the partition beam 12 for the first connecting member 41 to pass through directly, which can reduce the process difficulty and avoid affecting the strength of the partition beam 12 due to the punching.

[0042] The present disclosure does not limit the fuse box 3, and the fuse box 3 can be any fuse box known in the art. Figures 2-4 In the embodiments of the present disclosure, the fuse box 3 can include a second shell 31 and a fuse 32 arranged in the second shell 31. The fuse 32 can have a first connecting end 321 and a second connecting end 322. The first connecting end 321 is connected with the first connecting member 41, and the second connecting end 322 can be connected with the battery module of the battery pack through the second connecting member 42. In this way, a current path can be formed from the distribution box 2, the first connecting member 41, the first connecting end 321, the fuse 32, the second connecting end 322, the second connecting member 42 and the battery module. When the current is overloaded, the fuse 32 can be automatically fused to cut off the current path, thereby protecting the entire battery pack.

[0043] Similarly, the present disclosure does not limit the second connecting member 42, which can be a copper bar, an aluminum bar, etc.

[0044] The present disclosure does not limit the second connecting member 42, which can be a copper bar, an aluminum bar, etc. Figure 2 and Figure 6 In the embodiments of the present disclosure, the fuse box 3 can further include an upper cover 33 arranged on the second shell 31 to shield the fuse 32. By arranging the upper cover 33, the fuse 32 can be shielded, especially the two exposed connecting ends of the fuse 32. On the one hand, the risk of electric shock when touching the two exposed connecting ends of the fuse 32 by relevant personnel can be reduced, and on the other hand, the fuse 32 can be protected from water, impurities, etc. to affect the performance of the fuse box 3.

[0045] The present disclosure does not limit how the upper cover 33 is installed on the second shell 31, for example, in the embodiment shown in Figure 2 、 Figure 4 and Figure 6 , the two sides of the upper cover 33 can be respectively provided with elastic catches 332, and the two sides of the second shell 31 can be respectively provided with upwardly extending baffles 311, and the two elastic catches 332 can be elastically abutted between the two baffles 311 to limit the disengagement of the upper cover 33 from the second shell 31. Here, "upwardly extending" refers to the direction towards the cover body of the battery pack. When installing the upper cover 33, the two elastic catches 332 can be compressed and deformed by the two baffles 311, and after the two elastic catches 332 extend between the two baffles 311, they can respectively have a tendency to expand in a direction away from each other, thereby abutting the two baffles 311, so that the upper cover 33 is fixed to the second shell 31. When it is necessary to disassemble the upper cover 33 for maintenance, only an external force needs to be applied to the two elastic catches 332 to deform them in a direction towards each other, thereby releasing the abutting relationship with the baffles 311, so that the upper cover 33 can be disassembled.

[0046] In the embodiments of the present disclosure, the elasticity of the elastic catch 332 can be formed by its own structure, for example, it can be a Figure 6 U-shaped structure, so that it can form elastic deformation when it is extruded. In addition, in some other embodiments, the elasticity of the elastic catch 332 can also be formed by its own material, for example, it can be made of elastic materials such as rubber.

[0047] Further, in some embodiments, in order to improve the reliability of the installation of the upper cover 33 and avoid forced disengagement from the second shell 31, the opposite surfaces of the two baffles 311 can be respectively provided with clamping grooves, and the two elastic catches 332 can be respectively provided with protrusions for extending into the clamping grooves. This design is more reliable than simply abutting and relying on friction force for fixation.

[0048] Referring to Figure 2 and Figure 6 , in the embodiments of the present disclosure, the upper cover 33 can be provided with heat dissipation holes 331. The heat dissipation holes 331 can be round holes or long holes, and the number of heat dissipation holes 331 can be multiple. The provision of the heat dissipation holes 331 is beneficial to dissipating the heat in the safety box 3 and reducing the temperature, avoiding the existence of safety hazards due to overheating of the internal temperature.

[0049] Referring to Figure 3 and Figure 4In embodiments of this disclosure, the fuse box 3 may further include two heat sinks 34 installed within the second housing 31. The first connecting end 321 and the second connecting end 322 can respectively overlap the surface of the corresponding heat sink 34. The first connecting member 41 can overlap the surface of the first connecting end 321 facing away from the heat sink 34, and the second connecting member 42 can overlap the surface of the second connecting end 322 facing away from the heat sink 34. This overlapping connection method enables electrical connection between the copper busbar and the connecting end. Furthermore, since the overlapping position is the main source of heat for the fuse box 3 when energized, directly placing the overlapping position on the surface of the heat sink 34 facilitates rapid heat dissipation and prevents localized overheating.

[0050] Furthermore, in the embodiments of this disclosure, the first connecting end 321, the first connecting member 41, and the corresponding heat sink 34 can be connected and fixed by the first fastener 51, and the second connecting end 322, the second connecting member 42, and the corresponding heat sink 34 can be connected and fixed by the second fastener 52. The fastener can be a threaded component, such as a bolt. In this case, fastening holes need to be provided for the connecting end, the copper busbar, and the heat sink 34 respectively, so that the fasteners can pass through each fastening hole in sequence and connect and fix the three components, thereby ensuring the reliability of the electrical connection between the copper busbar and the connecting end, and ensuring the contact stability between the copper busbar and the connecting end and the heat sink 34, so that the heat generated by the copper busbar and the connecting end can be quickly conducted away and dissipated through the heat sink 34.

[0051] This disclosure does not limit the heat sink 34, for example in Figure 5 In the illustrated embodiment, the heat sink 34 may include a first heat sink 341 and a plurality of second heat sinks 342. The first connecting end 321 and the second connecting end 322 may respectively rest on the upper surface of the corresponding first heat sink 341. The plurality of second heat sinks 342 are arranged parallel to each other and spaced apart, and the plurality of second heat sinks 342 may be respectively connected to the lower surface of the first heat sink 341. With this design, due to the good thermal conductivity of aluminum, the heat generated at the connection points of the copper busbar and the connecting ends can be quickly transferred through the first heat sink 341 to the plurality of second heat sinks 342, and then the heat is quickly dissipated through the plurality of second heat sinks 342, and then rapidly cooled through the aforementioned heat dissipation holes 331. It should be noted that the upper surface of the first heat sink 341 refers to its surface facing the connecting ends and the copper busbar, that is, its direction towards the cover of the battery pack.

[0052] In the embodiments disclosed herein, the first heat sink 341 and the second heat sink 342 may be aluminum plates, copper plates, etc.

[0053] In embodiments of the present disclosure, the second housing 31 can be provided with a mounting groove for placing the heat dissipation member 34, and the heat dissipation member 34 can be clamped in the mounting groove by interference fit. Specifically, when the heat dissipation member 34 includes a first heat dissipation plate 341 and a second heat dissipation plate 342, the first heat dissipation plate 341 can be interference pressed in the mounting groove.

[0054] In order to ensure the reliability of the installation of the fuse 32 in the second housing 31, avoid loosening and falling off, etc., in embodiments of the present disclosure, the second housing 31 can be provided with an elastic clamping portion for limiting the disengagement of the fuse 32 from the second housing 31.

[0055] Specifically, referring to Figure 3 and Figure 4 , the elastic clamping portion can include a plurality of cantilever buckles 61 extending in the dismounting direction of the fuse 32, and the plurality of cantilever buckles 61 can be divided into two groups and oppositely arranged, for example, the number of each group is two, three, etc. Wherein, the cantilever buckle 61 can include a cantilever 611 and a clamping structure 612 provided at the end of the cantilever 611, and the clamping structure 612 can be a buckle, or also can be Figure 4 the arc-shaped protruding structure formed at the end of the cantilever 611 as shown in the above, as long as it can play a clamping role. And wherein, the fuse 32 can press the clamping structure 612 to drive the cantilever 611 to deform outwardly to allow the fuse 32 to extend into between the two groups of cantilever buckles 61 when installed, and the outward deformation here refers to the direction away from the other group of cantilever buckles 61. And when the fuse 32 is installed in place, the cantilever 611 can be elastically reset to clamp the fuse 32 from both sides by the two groups of clamping structures 612, for example, it can be clamped on the upper surface of the fuse 32 (the surface close to the cover of the battery pack), and the elasticity of the cantilever buckle 61 can be obtained due to the structure of the cantilever 611 itself. In addition, in some other embodiments, the clamping structure 612 can also be designed as an elastic structure, so that when installed, the fuse 32 can press the clamping structure 612 to deform, so that the fuse 32 can extend into between the two groups of cantilever buckles 61, and after the fuse 32 is installed in place, the clamping structure 612 can be elastically reset to clamp the fuse 32, and the present disclosure does not limit this.

[0056] According to a second aspect of the present disclosure, a vehicle is provided, which includes the above-mentioned battery pack, and since the vehicle has all the beneficial effects of the above-mentioned battery pack, they will not be repeated here.

[0057] In the detailed description above, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration specific aspects in which the disclosure can be practiced. In this regard, directional terminology, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and other commonly used terms, are used herein for the purpose of illustration only and are not intended to be limiting. Because the described devices can be positioned in a number of different orientations, the directional terminology can be used for illustration purposes only and is not limiting. It is to be understood that other aspects can be utilized and structural or logical changes can be made without departing from the scope of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.

[0058] It is to be understood that the features of the various aspects of the present disclosure described herein can be combined with each other, unless specifically noted otherwise. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items; similarly, "at least one of' includes any and all combinations of one or more of the associated listed items.

[0059] It should be understood that, unless otherwise specifically stated and limited, the terms "joined," "attached," "mounted," "connected," "linked," "fixed," and the like, as used herein, are to be construed broadly, e.g., as either fixed connections, or detachable connections, or integral; either mechanical, or electrical, or communicative with each other; either direct connections, or indirect connections through intermediaries; or internal communication or interaction between two elements, unless otherwise specifically limited. The specific meaning of the above terms in this context can be understood by those of ordinary skill in the art according to the specific circumstances.

[0060] Further, the word "over" as used in describing a component, element, or material layer "over" another component, element, or material layer in the surface "over" which it is formed or positioned can be used herein to mean that the component, element, or material layer is positioned "indirectly" on the surface, such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the word "over" as used in describing a component, element, or material layer "over" another component, element, or material layer in the surface "over" which it is formed or positioned can alternatively have the specific meaning that the component, element, or material layer is positioned "directly" on the surface, e.g., in direct contact with the surface.

[0061] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0063] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0064] Likewise, although the present disclosure has been described and illustrated with respect to one or more implementations, equivalent alterations and modifications will become apparent to those skilled in the art that do not depart from the true spirit and scope of the disclosure. The present disclosure includes all such modifications and alterations and is limited only by the scope of the following claims. In particular regard to the various functions performed by the above described components (e.g., elements, resources, etc.), the terms (including a reference to a "means") used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the described function (e.g., a functional equivalent), even though not structurally equivalent to the disclosed structure. In addition, although a particular feature of the disclosure can have been disclosed with respect to only one of several implementations, other implementations can include the particular feature. For example, the disclosure can be implemented with respect to other implementations that incorporate the particular feature, and that implement other features as disclosed herein, and each of the various implementations have a reasonable expectation of support. Furthermore, to the extent that the terms "includes", "including", "has", "have", "having", or variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising".
