[0013] Optionally, the first frame body, the connecting portion and the first supporting portion are integrally formed in a plate shape; and / or the second frame body and the second supporting portion are integrally formed in a plate shape.

[0035] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0036] It should be noted that the relative arrangement of the components, numerical expressions and values set forth in these embodiments are not limiting to the scope of the present application unless specifically stated otherwise.

[0037] It should be understood that the sizes of the various parts shown in the drawings are not necessarily drawn to scale for the sake of convenience.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting to the scope of the application or its applications or uses.

[0039] It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present application should have their ordinary meaning in the field of the present application to those skilled in the art. The terms "first", "second" and similar terms used in the embodiments of the present application do not denote any order, quantity or importance, but are only used to distinguish different components. The terms "include" or "contain" and similar terms mean that the elements or objects before the term encompass the elements or objects listed after the term and their equivalents, without excluding other elements or objects. The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "up", "down", "left", "right" and the like are only used to indicate relative positional relationships, and when the absolute positions of the described objects are changed, the relative positional relationships can also be changed accordingly.

[0040] In order to avoid relative movement between the control device 600 and the battery cell, a connection relationship can be established between the control device 600 and the battery cell to ensure that the positional relationship between the two is relatively stable, thereby ensuring that the two can be electrically connected more reliably through the sampling member 231.

[0041] Therefore, the embodiments of the present application provide a battery pack support, such as Figure 1 , Figure 1A schematic view of a battery pack bracket is shown, the battery pack bracket comprising: a first bracket body 300, the first bracket body 300 being connected with a connecting portion 400 and a first supporting portion 500, the connecting portion 400 being configured to connect with a battery pack 200, and the first supporting portion 500 being configured to connect with a lower case 100 of the battery pack. As shown in Figure 2 , Figure 2 An exploded schematic view of the battery pack bracket is shown, the first bracket body 300 being provided with a first mounting position 310.

[0042] As shown in Figure 3 , Figure 3 A schematic view of a part of the battery pack comprising the battery pack bracket is shown, and the following will be further described by taking the structure shown in Figure 3 as an example.

[0043] For example, the battery pack 200 can comprise a cell stack 210, the cell stack 210 comprising a plurality of cells arranged along a first direction (e.g. the X direction in Figure 3 The battery pack 200 further comprises an end plate 220 connected to at least one side of the cell stack 210 along the first direction.

[0044] For example, the connecting portion 400 can be connected to the end plate 220 of the battery pack 200; or, can be connected between the end plate 220 and the cell stack 210.

[0045] For example, the connecting portion 400 and the battery pack 200 can be connected by welding, bonding, plugging, clamping, fastener connection or the like.

[0046] For example, the first supporting portion 500 and the lower case 100 can be connected by welding, bonding, plugging, clamping, fastener connection or one-piece forming or the like.

[0047] For example, the first supporting portion 500 can be located below the first bracket body 300, so that the first bracket body 300 is erected in the lower case 100.

[0048] In the embodiment, the first frame body 300 is connected with the lower box body 100 through the first support part 500 and connected with the battery pack 200 through the connecting part 400. At this time, the first frame body 300 establishes a connection relationship with the lower box body 100 and the battery pack 200, and then the relative positions among the first frame body 300, the lower box body 100 and the battery pack 200 are relatively fixed. The first mounting position 310 of the first frame body 300 can be used to mount the control device 600, and correspondingly, the relative positions among the control device 600 located at the first mounting position 310, the lower box body 100 and the battery pack 200 are also relatively fixed, so that the sampling part 231 between the control device 600 and the battery cell of the battery pack 200 can be prevented from being pulled by external force due to the relative movement of the two.

[0049] The battery pack support provided in the embodiment is characterized in that the first frame body 300 is connected with the lower box body 100 and the battery pack 200 through the first support part 500 and the connecting part 400 respectively, so that the relative positions among the first frame body 300, the lower box body 100 and the battery pack 200 are relatively fixed. When the control device 600 is mounted on the first mounting position 310 of the first frame body 300, the lower box body 100 and the battery pack 200 can provide reliable support for the control device 600, so that the control device 600 can be kept at a preset position in the lower box body 100 of the battery pack. Meanwhile, since the relative positions among the control device 600 and the battery pack 200 are relatively fixed, the sampling part 231 between the control device 600 and the battery pack 200 can be reliably electrically connected with the two, so that the control device 600 can effectively control the battery pack 200, and the safety of the battery pack is improved.

[0050] For example, Figure 2 In some embodiments, the first frame body 300 includes a first mounting part 320 and a second mounting part 330 connected with each other, the first mounting part 320 has a first mounting surface 321, the second mounting part 330 has a second mounting surface 331 intersecting with the first mounting surface 321, the first mounting position 310 is arranged on the first mounting surface 321, and the second mounting surface 331 is provided with a sampling mounting position 350.

[0051] For example, the first mounting part 320 is a horizontally arranged plate-shaped structure for horizontally supporting the control device 600, and the second mounting part 330 is a vertically arranged plate-shaped structure, and the second mounting part 330 can be surface-to-surface attached with the end plate 220 of the battery pack 200.

[0052] For example, the first mounting surface 321 is an upper surface of the first mounting part 320 (i.e. the first mounting surface 321 faces the opening of the lower box body 100), and the second mounting surface 331 is located on one side of the first mounting surface 321.

[0053] For example, the sampling element 231 may include a connecting wire, a wire harness, or a flexible circuit board.

[0054] like Figure 4 , Figure 4 A partial schematic diagram showing the connection between the battery pack bracket and the battery pack 200 is shown. The battery pack 200 also includes a busbar assembly 230 electrically connected to each battery cell. The sampling element 231 of the busbar assembly 230 extends to the sampling mounting position 350 of the second mounting surface 331.

[0055] like Figure 5 , Figure 5 The diagram shows the connection between the battery pack bracket, the sampling component 231, and the control device 600. The sampling component 231 (via terminals) is electrically connected to the control device 600. After the control device 600 is installed at the first mounting position 310 of the first mounting surface 321, the relative position between the control device 600 and the battery pack bracket is fixed. The sampling component 231 can be arranged and placed at the sampling mounting position 350, thereby positioning the sampling component 231 on the second mounting surface 331. This avoids the sampling component 231 from hindering subsequent assembly work and also reduces the risk of the sampling component 231 being pulled by external forces.

[0056] like Figure 2 and Figure 3 In some embodiments, the connecting portion 400 is connected to the top of the battery pack 200, the first mounting portion 320 is located below the connecting portion 400, and the second mounting portion 330 is connected between the connecting portion 400 and the first mounting portion 320.

[0057] For example, the longitudinal cross-section of the connecting part 400, the second mounting part 330 and the first mounting part 320 is Z-shaped.

[0058] The connecting part 400 is connected to the top of the battery pack 200, allowing the battery pack 200 to support the connecting part 400. In other words, the first main body 300 can be hung on the battery pack 200 through the connecting part 400, which helps to make the connection between the first main body 300 and the battery pack 200 more stable and reliable. Meanwhile, the first mounting part 320 is located below the connecting part 400, that is, the first mounting part 320 is located inside the lower housing 100, and the first mounting part 320 is along the height direction of the lower housing 100 (e.g., ...). Figure 3 The position in the Z direction (of the battery pack) is not limited by the height of the battery pack 200, making the design more flexible.

[0059] like Figure 1 and Figure 2In some embodiments, the battery pack bracket further comprises a second bracket body 700 spaced apart from the first mounting portion 320, and a second supporting portion 800 is connected between the first mounting portion 320 and the second bracket body 700. The second bracket body 700 is provided with a second mounting position 711.

[0060] It should be noted that the second mounting position 711 and the first mounting position 310 have similar structures and functions, and will not be described here.

[0061] The position of the first mounting portion 320 along the height direction of the lower box body 100 can be adjusted by adjusting the size of the second mounting portion 330, so that a larger space can be formed above or below the first mounting portion 320 as needed. Specifically, when a larger space above the first mounting portion 320 is needed, the size of the second mounting portion 330 can be adjusted to make the first mounting portion 320 closer to the bottom of the lower box body 100; when a larger space below the first mounting portion 320 is needed, the size of the second mounting portion 330 can be adjusted to make the first mounting portion 320 farther away from the bottom of the lower box body 100.

[0062] As Figure 4 and Figure 5 , the larger space above or below the first mounting portion 320 can not only be used to install a single layer of control devices 600, but also can form a second mounting position 711 stacked on the first mounting position 310 by connecting the second bracket body 700, so that the battery pack bracket can install at least two layers of control devices 600, thereby improving the space utilization rate inside the battery pack.

[0063] Meanwhile, in the present embodiment, the second bracket body 700 can be erected on the first mounting portion 320 by the second supporting portion 800, avoiding interference between the second bracket body 700 and the control devices 600 mounted on the first mounting position 310.

[0064] As Figure 2 In some embodiments, the second bracket body 700 is connected to the first mounting surface 321; the second bracket body 700 has a third mounting surface 710, the third mounting surface 710 is away from the first mounting surface 321, and the second mounting position 711 is arranged on the third mounting surface 710.

[0065] Generally, the first installation surface 321 is located on the upper surface of the first installation portion 320 for facilitating installation of the control device 600 on the first installation site 310. Similarly, the second rack body 700 can be connected to the first installation surface 321 through the second support portion 800, and the surface of the second rack body 700 away from the first installation surface 321, i.e., the upper surface of the second rack body 700, is configured as the third installation surface 710 for setting the second installation site 711, so as to facilitate installation of the control device 600 on the second installation site 711.

[0066] For example, Figure 1 and Figure 2 In some embodiments, the second installation surface 331 is located on one side of the third installation surface 710.

[0067] For example, along the thickness direction (e.g., the Z direction in Figure 1 of the second rack body 700, at least one side edge of the second installation surface 331 exceeds the third installation surface 710.

[0068] In combination with the foregoing, the sampling installation site 350 on the second installation surface 331 is used to connect the sampling member 231, so that when the battery pack support installs two layers of control devices 600, not only the control device 600 connected to the sampling member 231 (hereinafter referred to as the first sampling member) on the first installation site 310 can be connected to the sampling installation site 350, but also the control device 600 connected to the sampling member 231 (hereinafter referred to as the second sampling member) on the second installation site 711 can be connected to the sampling installation site 350.

[0069] The beneficial effect of connecting the second sampling member by the sampling installation site 350 is the same as the beneficial effect of connecting the first sampling member as described above, and will not be described here again.

[0070] For example, Figure 2 In some embodiments, the first installation surface 321 is connected with a connecting member 900, and the region of the first installation surface 321 corresponding to the connecting member 900 is configured as the first installation site 310; and / or, the third installation surface 710 is connected with a connecting member 900, and the region of the third installation surface 710 corresponding to the connecting member 900 is configured as the second installation site 711.

[0071] For example, a plurality of connecting members 900 are arranged along the edges of the first installation site 310, and a plurality of connecting members 900 are arranged along the edges of the second installation site 711.

[0072] For example, the connecting member 900 can be a screw, a threaded column or a nut.

[0073] Exemplarily, the connecting piece 900 can be connected to the first mounting surface 321 or the second mounting surface 331 by welding, bonding, riveting, clamping or one-piece forming, etc.

[0074] The controller 600 placed in the first mounting position 310 or the second mounting position 711 can be fixed by the connecting piece 900, so that the first controller 600 can be stably kept in the first mounting position 310 or the second mounting position 711.

[0075] For example, Figure 2 In some embodiments, the connecting piece 900 includes a threaded column.

[0076] Exemplarily, the threaded column is welded or riveted to the first frame body 300 or the second frame body 700.

[0077] Taking the threaded column connected to the first frame body 300 as an example, when the threaded column is connected to the first frame body 300, the threaded column is vertically fixed on the first mounting surface 321. When installing the controller 600, the mounting lug of the controller 600 can be sleeved on the threaded column, and the controller 600 can be locked by a nut, so that the installation of the controller 600 is completed. The operation is relatively simple, and the assembly difficulty is relatively low. At the same time, using the threaded column as the connecting piece 900 can reduce the preparation cost of the battery pack support, which is conducive to mass production.

[0078] For example, Figure 2 In some embodiments, the first frame body 300, the connecting part 400 and the first supporting part 500 are one-piece formed plate-shaped structures; and / or, the second frame body 700 and the second supporting part 800 are one-piece formed plate-shaped structures.

[0079] Exemplarily, the first frame body 300, the connecting part 400 and the first supporting part 500 can be one-piece formed by a plate material through a stamping forming process. Similarly, the second frame body 700 and the second supporting part 800 can be one-piece formed by the same process.

[0080] Exemplarily, taking the first mounting part 320 in the plate-shaped structure as an example, for the part close to the edge and not provided with the first mounting position 310 and the connecting piece 900, the folded edge 340 can be formed by cutting and bending. On the one hand, it can further avoid interference between the battery pack support and other structural parts in the lower box body 100, and on the other hand, the folded edge 340 can also play the role of a reinforcing rib to improve the strength of the first mounting part 320.

[0081] By the plate-shaped structure, the first bracket body 300, the connecting part 400 and the first supporting part 500 are integrally formed, and the second bracket body 700 and the second supporting part 800 are integrally formed. On the one hand, the weight of the battery pack bracket as a whole can be reduced. On the other hand, the plate-shaped structure is simple to process and has low material cost, thus helping to reduce the overall preparation cost of the battery pack bracket and being conducive to mass production.

[0082] Based on the same inventive concept, in combination with the description of the battery pack bracket in the above embodiments, the battery pack provided in the present embodiment has the corresponding technical effects of the battery pack bracket in the above embodiments, which will not be described here again.

[0083] As Figure 3 A battery pack includes a lower box body 100, at least one battery pack 200, and a battery pack bracket as described in the above embodiments.

[0084] Illustratively, the battery pack can further include an upper box body covering the lower box body 100. The upper box body and the lower box body 100 enclose a containing space. The battery pack 200, the battery pack bracket, and the control device 600 mounted on the battery pack bracket are all located in the containing space.

[0085] As Figure 3 In some embodiments, the battery pack 200 includes a cell stack 210 and an end plate 220 connected to at least one side of the cell stack 210. The connecting part 400 is connected to the end plate 220.

[0086] Illustratively, the connecting part 400 of the battery pack bracket can be connected to the end plate 220 by a screw.

[0087] In the battery pack 200, the end plate 220 can be used to position the cell stack 210. Therefore, generally, the end plate 220 has a large strength. When the battery pack bracket is connected to the end plate 220 by the connecting part 400, the end plate 220 with a large strength can reliably support the battery pack bracket as a whole, ensure the connection between the battery pack bracket and the battery pack 200 to be more reliable, and avoid the relative movement between the battery pack bracket and the battery pack 200.

[0088] As Figure 3 In some embodiments, the battery pack includes at least two battery packs 200. The same connecting part 400 is connected between the two end plates 220 of the adjacent two battery packs 200.

[0089] Illustratively, at least two connecting parts 400 are arranged at intervals along the width direction (e.g., the Y direction in Figure 3 of the lower box body 100.

[0090] In addition to the above functions, the connecting part 400 can also connect and fix the end plates 220 of the two adjacent battery packs 200, so as to ensure that the two adjacent battery packs 200 cannot move relative to each other at least along the width direction of the lower box body 100, and further ensure that the battery pack 200 can be kept at the preset position in the lower box body 100.

[0091] As Figure 3 and Figure 4 In some embodiments, the battery pack further comprises a sampling member 231; the first rack body 300 is provided with a sampling mounting position 350, and at least part of the sampling member 231 is arranged at the sampling mounting position 350.

[0092] For example, the sampling member 231 can be connected to the sampling mounting position 350 by means of adhesive or a cable tie.

[0093] As Figure 6 , Figure 6 Part of the top view of the battery pack is shown, and in some embodiments, the lower box body 100 comprises a bottom plate 110 and a frame structure formed by the second end plate 150, the two side plates 120, the two corner beams 140 and the first end plate 130, and the frame structure is connected with the bottom plate 110. Specifically, along the extension direction of the side plate 120 (such as the X direction in Figure 6 , one end of the side plate 120 is connected with the second end plate 150, and the other end is connected with the first end plate 130 through the corner beam 140.

[0094] As Figure 7 , Figure 7 An enlarged view of part A in Figure 6 is shown, and the corner beam 140 is connected with a corner beam connecting part 141 on the side close to the inside of the lower box body 100, and the first support part 500 of the battery pack support is connected with the corner beam connecting part 141.

[0095] As Figure 8 , Figure 8 A connection diagram of the battery pack support and the corner beam 140 is shown, and the first support part 500 is located above the corner beam connecting part 141, so that the corner beam connecting part 141 provides support to the whole battery pack support through the first support part 500.

[0096] For example, the corner beam 140 can be provided with an inner cavity, and the inner cavity can be in communication with the internal space of the lower box body 100, so that when the first support part 500 is connected with the corner beam connecting part 141, part of the first support part 500 can be inserted into the inner cavity, so as to avoid interference between the first support part 500 and the corner beam 140.

[0097] For example, at least two corner beam connecting parts 141 are arranged at intervals along the height direction of the corner beam 140 (such as the Z direction in Figure 8 ).

[0098] For example, the first support 500 is connected to the corner beam connection 141 by fasteners such as bolts.

[0099] Combination Figure 3 and Figure 6 Along the length of the lower housing 100 (e.g.) Figure 6 In the X direction, the battery pack 200 is located behind the battery pack bracket, and the corner beam 140 is located in front of the battery pack bracket.
