[0038] The circuit board 210 includes a first surface 211 and a second surface 212. The first surface 211 and the second surface 212 are arranged opposite to each other along the thickness direction of the circuit board 210 (i.e., the Y-axis direction). The circuit board 210 also includes a through-hole 213. The through-hole 213 passes through the first surface 211 and the second surface 212. It can be understood that the through-hole 213 passes through the circuit board 210 along the thickness direction of the circuit board 210. The through-hole 213 is used for passing the fastener D. There are multiple through-holes 213. Exemplarily, the circuit board 210 is a roughly rectangular thin plate. There are eight through-holes 213. The eight through-holes 213 are arranged around the edge of the circuit board 210 and are spaced apart from each other.

[0039] The adapter plate 220 includes an adapter plate body 221, a fixed edge 222, and a fixed post 223. The fixed edge 222 is bent and connected to the adapter plate body 221. The fixed post 223 is protruded from the adapter plate body 221 and is located on either side of the fixed edge 222 in the thickness direction (i.e., the Y-axis direction) of the adapter plate body 221.

[0040] Specifically, the adapter plate body 221 includes a third surface 224 and a fourth surface 225. The third surface 224 and the fourth surface 225 are disposed opposite to each other along the thickness direction of the adapter plate body 221. Exemplarily, the adapter plate body 221 is a substantially rectangular thin plate.

[0041] The fixed edge 222 is protruding from the fourth surface 225 of the adapter plate 221 and is connected to one side of the adapter plate 221 in the height direction (i.e., the Z-axis direction). The extension direction of the fixed edge 222 is perpendicular to the adapter plate 221. The fixed edge 222 is used to connect to the mounting bracket 300. The number of fixed edges 222 can be one or more. Exemplarily, the number of fixed edges 222 is two. The two fixed edges 222 are spaced apart along the length direction of the adapter plate 220 (i.e., the X-axis direction).

[0042] The fixed edge 222 includes a fixing hole 226 . The fixing hole 226 extends through the fixed edge 222 along its thickness direction (i.e., the Z-axis direction). The fixing hole 226 is used to pass the locking accessory C through. There are multiple fixing holes 226 . For example, there are two fixing holes 226 . Each fixed edge 222 has one fixing hole 226 .

[0043] The fixing column 223 is protruded from the third surface 224 of the adapter plate 221. The fixing column 223 includes a fixing groove 227.

That is, the side wall of the fixing groove 227 has a thread, which is used to cooperate with the fastener D. The number of fixing columns 223 is the same as the number of through-holes 213. The number of fixing columns 223 is eight. The eight fixing columns 223 are arranged around the edge of the adapter plate 221 and are spaced apart from each other.

[0044] It should be noted that the number of fasteners D is the same as the number of through-holes 213. The number of fasteners D can be multiple. Exemplarily, the number of fasteners D is eight.

[0045] The circuit board 210 is mounted on the adapter plate 220. The second surface 212 of the circuit board 210 is opposite and spaced apart from the third surface 224 of the adapter plate body 221. Along the Y-axis, each through-hole 213 of the circuit board 210 is aligned with a fixing post 223 of the adapter plate 220. Each fastener D is inserted through a first through-hole 213 and a fixing post 223 and received within a fixing slot 227 of a fixing post 223, thereby removably connecting the circuit board 210 to the adapter plate 220.

[0046] Please refer to Figure 2 、 Figure 4 and Figure 5 , Figure 4 for Figure 2 The schematic structural diagram of the mounting bracket 300 and the mounting front plate 320 is shown. Figure 5 for Figure 2 The structure diagram of the mounting bracket 300 after the mounting plate 330 is shown.

Every two first connecting holes 3231 are provided on one first connecting edge 323, and the two first connecting holes 3231 on one first connecting edge 323 are spaced apart along the X-axis direction.

[0055] The structure of the mounting rear plate 330 is similar to that of the mounting front plate 320. The difference is that the mounting rear plate 330 does not include the mounting ears 322. The mounting rear plate 330 includes a rear plate body 331 and a second connecting edge 332. The rear plate body 331 includes a second outer surface 3311 and a second inner surface 3312. The second outer surface 3311 and the second inner surface 3312 are arranged opposite to each other along the thickness direction (i.e., the Y-axis direction) of the mounting rear plate 330. The second outer surface 3311 faces away from the receiving space M. The second inner surface 3312 faces the receiving space M.

Every two second connecting holes 3321 are provided on one second connecting edge 332, and the two second connecting holes 3321 on one second connecting edge 332 are spaced apart along the Y-axis direction.

[0058] It can be understood that the mounting bracket 300 includes a bracket body 310, a mounting ear 322, a first connecting edge 323 and a second connecting edge 332. The bracket body 310 includes an outer side surface 311 and an inner side surface 312. The inner side surface 312 and the outer side surface 311 are arranged opposite to each other along the thickness direction of the bracket body 310. The mounting ear 322, the first connecting edge 323 and the second connecting edge 332 are all protruded from the outer side surface 311 of the bracket body 310. The first connecting edge 323 and the second connecting edge 332 are respectively located on opposite sides of the length direction (i.e., the Y-axis direction) of the bracket body 310. The mounting front plate 320, the mounting rear plate 330 and the two mounting side plates 340 can be an integrated structure, or the mounting front plate 320, the mounting rear plate 330 and the two mounting side plates 340 can be a separate structure. The first outer surface 3211 of the front panel 320, the second outer surface 3311 of the rear panel 330, and the surfaces of the two side panels 340 facing away from the receiving space M together form the outer side surface 311 of the bracket body 310. The first inner surface 3212 of the front panel 320, the second inner surface 3312 of the rear panel 330, and the surfaces of the two side panels 340 facing the receiving space M together form the inner side surface 312 of the bracket body 310.

[0059] The mounting bracket 300 also includes a lifting lug 350. The lifting lug 350 is protruded from the outer side surface 311 of the bracket body 310. The lifting lug 350 is used to lift the mounting bracket 300 equipped with the battery module 400 into the housing 100. There are multiple lifting lugs 350. For example, there are four lifting lugs 350. Two lifting lugs 350 are connected to the mounting front plate 320, and the other two lifting lugs 350 are connected to the mounting rear plate 330. The two lifting lugs 350 connected to the mounting front plate 320 and the two lifting lugs 350 connected to the mounting rear plate 330 are symmetrically arranged along the central axis of the mounting bracket 300 in the width direction to ensure stability when lifting the mounting bracket 300.

[0060] The mounting bracket 300 also includes a support edge 360. The support edge 360 ​​is protruded from the inner side surface 312 of the bracket body 310. The support edge 360 ​​is located at one end of the bracket body 310 away from the mounting ear 322. The support edge 360 ​​extends in a direction away from the bracket body 310. The support edge 360 ​​is used to support the battery module 400 and ensure that the battery module 400 does not fall from the mounting bracket 300 when the battery module 400 and the mounting bracket 300 are hoisted into the shell 100. The number of support edges 360 is one or more. Exemplarily, the number of support edges 360 is two.

The first opening 102 is connected to the accommodating cavity 101. Along the Z-axis direction, the first opening 102 is away from the base plate 10 and opposite to the base plate 10. The cover plate 30 covers the side of the peripheral side plate 20 facing away from the base plate 10 and closes the first opening 102. In other words, the cover plate 30 and the bottom plate 10 are opposite to each other and spaced apart along the thickness direction (ie, the Z-axis direction) of the power supply device 1000 , and the peripheral side plate 20 is connected between the bottom plate 10 and the cover plate 30 .

[0065] The peripheral side panels 20 include a front panel 21, a rear panel 22, and two side panels 23. The two side panels 23 are respectively connected to opposite sides of the base plate 10 in the X-axis direction, and each side panel 23 extends in the Y-axis direction. The front panel 21 and the rear panel 22 are connected between the two side panels 23 and are arranged opposite to each other in the Y-axis direction. The base plate 10 and the two side panels 23 enclose the second opening 103 of the shell 100. The second opening 103 is connected to the accommodating cavity 101. Along the length direction of the power supply device 1000 (i.e., the Y-axis direction), the second opening 103 is away from the rear panel 22. The front panel 21 is detachably connected to the base plate 10 and the two side panels 23 and is enclosed in the second opening 103. The base plate 10, the rear panel 22, and the two side panels 23 can be integrally formed. Alternatively, the base plate 10, the rear panel 22, and the two side panels 23 can be separately formed. This application does not impose strict restrictions on this.

[0066] The peripheral side plate 20 is also provided with a plurality of electrode terminals 24. The plurality of electrode terminals 24 are all connected to the front panel 21. The electrode terminals 24 are used to achieve electrical connection between the circuit board 210 and electronic devices outside the power supply device 1000. Exemplarily, the electrode terminals 24 include a positive terminal and a negative terminal. The positive terminal and the negative terminal are spaced apart along the X-axis direction. The positive terminal is used to connect to the positive electrode of the circuit board 210 and the electronic devices outside the power supply device 1000. The negative terminal is used to connect to the negative electrode of the circuit board 210 and the electronic devices outside the power supply device 1000.

[0067] In other embodiments, the peripheral side plate 20 may also be provided with components such as sampling devices, monitoring and protection circuits, electrical interfaces, communication interfaces, and thermal management devices. The sampling devices may collect parameters such as the total voltage of the battery module 400, the voltage, power, charge and discharge current, and ambient temperature of the individual cells within the battery module 400, etc. The monitoring and protection circuit is used to compare the data collected by the sampling device with the safety data to determine whether to execute or not execute the protection step. The thermal management device is used to compare the temperature collected by the sampling device with the safety temperature to determine whether to execute or not execute the protection step. Of course, the electronic device may also be provided as other components.

[0068] The housing 100 also includes a first support member 40 and a second support member 50. Both the first support member 40 and the second support member 50 are protruding from the base plate 10. The first support member 40 and the second support member 50 are located on opposite sides of the mounting bracket 300 along the Y-axis, and are detachably connected to the mounting bracket 300 to positionally secure the mounting bracket 300 within the accommodating cavity 101. The first support member 40 is located on the side of the mounting bracket 300 closest to the front panel 21. The second support member 50 is located on the side of the mounting bracket 300 closest to the rear panel 22 and is spaced apart from the rear panel 22.

[0069] Specifically, the first support member 40 includes a first plate 41 and a second plate 42. The first plate 41 is connected to the base plate 10 and extends perpendicularly to the base plate 10. The first plate 41 and the second plate 42 are connected by a bend. The second plate 42 extends perpendicularly to the first plate 41 and is opposite and spaced from the base plate 10 along the Z-axis. Exemplarily, the first plate 41 and the second plate 42 are both rectangular thin plates.

[0070] The second plate body 42 includes a first surface 421 and a second surface 422. The first surface 421 and the second surface 422 are arranged opposite to each other along the thickness direction of the second plate body 42. The first surface 421 faces the base plate 10. The second surface 422 faces away from the base plate 10. The second plate body 42 also includes a first assembly hole 423. The first assembly hole 423 passes through the first surface 421 and the second surface 422. It can be understood that the first assembly hole 423 passes through the second plate body 42 along the thickness direction of the second plate body 42 (i.e., the Z-axis direction). The first assembly hole 423 is used for the first connecting member A to pass through. The number of first assembly holes 423 is multiple. For example, the number of first assembly holes 423 is four. Along the length direction of the second plate body 42 (i.e., the Y-axis direction), the four first assembly holes 423 are spaced apart on the second plate body 42.

[0071] The first support member 40 also includes a reinforcing rib 43. Along the Z-axis direction, the reinforcing rib 43 is connected between the second plate 42 and the base plate 10. The reinforcing rib 43 is used to improve the structural strength of the first support member 40. The reinforcing rib 43 can be, but is not limited to, a plate, a column, etc. The number of reinforcing ribs 43 can be one or more. For example, the reinforcing rib 43 is a rectangular plate. The number of reinforcing ribs 43 is three. The three reinforcing ribs 43 are arranged at intervals along the X-axis direction. In some embodiments, the first support member 40 may not include the reinforcing rib 43, provided that the structural strength of the first support member 40 is met.

[0072] The structure of the second support member 50 may be the same as or different from that of the first support member 40. In this embodiment, the structure of the second support member 50 is different from that of the first support member 40, and the second support member 50 does not include reinforcing ribs. The second support member 50 includes a third plate 51 and a fourth plate 52. The third plate 51 is connected to the base plate 10, and the extension direction of the third plate 51 is perpendicular to the base plate 10. The third plate 51 and the fourth plate 52 are connected by bending. The extension direction of the fourth plate 52 is perpendicular to the third plate 51, and the fourth plate 52 is opposite to and spaced from the base plate 10 along the Z-axis direction. Exemplarily, the third plate 51 and the fourth plate 52 are both rectangular thin plates.

[0073] The fourth plate 52 includes a third surface 521 and a fourth surface 522. The third surface 521 and the fourth surface 522 are arranged opposite to each other along the thickness direction of the fourth plate 52. The third surface 521 faces the base plate 10. The fourth surface 522 faces away from the base plate 10. The fourth plate 52 also includes a second assembly hole 523. The second assembly hole 523 passes through the third surface 521 and the fourth surface 522 of the fourth plate 52. It can be understood that the second assembly hole 523 passes through the fourth plate 52 along the thickness direction of the fourth plate 52 (i.e., the Z-axis direction). The second assembly hole 523 is used to allow the second connecting member B to pass through. There are multiple second assembly holes 523. Exemplarily, there are four second assembly holes 523. Four second assembly holes 523 are spaced apart on the fourth plate 52 along the length direction of the fourth plate 52 (i.e., the Y-axis direction).

[0074] It should be noted that the first plate 41 of the first support member 40 and the third plate 51 of the second support member 50 are opposite and spaced apart along the length direction of the housing 100. The second plate 42 of the first support member 40 and the fourth plate 52 of the second support member 50 extend in opposite directions along the length direction of the housing 100.

[0075] The housing 100 also includes a clamping portion 60. The clamping portion 60 is protruding from the base plate 10. Along the Y-axis direction, the clamping portion 60 is located on the side of the first support member 40 facing away from the second support member 50. The clamping portion 60 includes a clamping slot 61. The clamping slot 61 is located at the end of the clamping portion 60 away from the base plate 10. The clamping slot 61 is recessed at the end of the clamping portion 60 away from the base plate 10 and is recessed toward the base plate 10. The clamping slot 61 is used to accommodate part of the adapter plate 220 and to limit and clamp the adapter plate 220. The clamping portion 60 can be, but is not limited to, a plate body, a column, etc. The number of the clamping portions 60 can be one or more. For example, the clamping portion 60 is a plate body. The number of the clamping portions 60 is two. The two clamping portions 60 are spaced apart along the X-axis direction and are used to clamp the two ends of the adapter plate 220 in the length direction.

[0076] It should be noted that the card slot 61 is protruding along the Y-axis direction compared to the second plate body 42. At the same time, the groove depth of the card slot 61 (that is, the dimension of the card slot 61 along the Z-axis direction) is greater than or equal to 2 mm and less than or equal to 3 mm, so as to meet the requirement of the card slot 61 to limit the adapter plate 220 in the Z-axis direction.

[0077] In this embodiment, along the Y-axis, the retaining portion 60 is connected to the end of the reinforcing rib 43 facing away from the first plate 41, and forms an integral structure with the reinforcing rib 43. The retaining groove 61 of the retaining portion 60 is provided at the end of the retaining portion 60 facing the reinforcing rib 43. It will be understood that the retaining groove 61 is formed by a recessed portion at the connection between the reinforcing rib 43 and the retaining portion 60.

[0078] Exemplarily, the two clamping portions 60 are connected to any two reinforcing ribs 43. Preferably, the two clamping portions 60 are connected to two reinforcing ribs 43 at opposite ends of the first support member 40 in the longitudinal direction (i.e., the X-axis direction) to ensure symmetry in the force applied to the adapter plate 220. In some embodiments, there are three clamping portions 60, each connected to a reinforcing rib 43, which is more conducive to retaining the adapter plate 220 in place.

[0079] Please refer to Figure 8 、 Figure 9 and Figure 10 , Figure 8 for Figure 2 A schematic structural diagram of the mounting bracket 300 and the housing 100 of the power supply device 1000, Figure 9 for Figure 2 The schematic structural diagram of the adapter plate 220, the mounting bracket 300 and the housing 100 of the power supply device 1000 is shown in FIG. Figure 10 for Figure 2 The schematic diagram of the structure of the circuit board assembly 200, the mounting bracket 300 and the housing 100 is shown.

[0080] It should be noted that, in order to better illustrate the positional relationship between the mounting bracket 300 and the housing 100, Figure 8 、 Figure 9 and Figure 10 The battery module 400 is not shown in the figures. In fact, the mounting bracket 300 and the battery module 400 are assembled outside the housing 100 and then hoisted into the housing 100. Figure 9 The positional relationship among the adapter plate 220 , the mounting bracket 300 and the first support member 40 is merely illustrated, and does not refer to the assembly order.

[0081] The mounting bracket 300 is installed in the accommodating cavity 101 of the housing 100 and contacts the bottom plate 10. The bracket body 310 is spaced apart from the peripheral side plate 20. The second plate 42 of the first support member 40 extends in a direction away from the mounting bracket 300. The fourth plate 52 of the second support member 50 extends in a direction away from the mounting bracket 300. The front plate 321 of the mounting front plate 320 faces the first plate 41 of the first support member 40. The first connecting edge 323 of the mounting front plate 320 and the second plate 42 of the first support member 40 are stacked along the Z-axis direction. The first connecting hole 3231 of each first connecting edge 323 is coaxially arranged with a first assembly hole 423 on the second plate 42. The first connecting member A is inserted through the first connecting hole 3231 and the first assembly hole 423 to detachably connect the mounting bracket 300 to the first support member 40. At the same time, the rear plate body 331 of the mounting rear plate 330 faces the third plate body 51 of the second support member 50. The second connecting edge 332 of the mounting rear plate 330 and the fourth plate body 52 of the second support member 50 are stacked along the Z-axis direction. The second connecting hole 3321 of each second connecting edge 332 is coaxially arranged with a second assembly hole 523 on the fourth plate body 52. ​​The second connecting member B is inserted through the second connecting hole 3321 and the second assembly hole 523 to detachably connect the mounting bracket 300 to the second support member 50.

[0082] like Figure 9 and Figure 10 As shown, the circuit board assembly 200 is installed in the accommodating cavity 101 of the housing 100. The circuit board 210 and the adapter plate 220 are both perpendicular to the base plate 10. It will be appreciated that the circuit board assembly 200 is locked to the outer side 311 of the bracket body 310, which helps save space within the power supply device 1000, thereby improving the volumetric energy density of the power supply device 1000. The adapter plate 220 is located on the side of the first support member 40 facing away from the mounting bracket 300. The fourth surface 225 of the adapter plate body 221 faces the first support member 40, and the adapter plate 220 is inserted into the slot 61 along the Z-axis. The adapter plate body 221 of the adapter plate 220 is partially accommodated in the slot 61 of the retaining portion 60, thereby facilitating initial positioning of the adapter plate 220 within the housing 100. This facilitates installation or removal of the circuit board assembly 200 from the mounting bracket 300 after initial positioning within the housing 100. At the same time, the slot 61 prevents the adapter plate 221 from moving in the Y-axis direction and is used to release the stress generated when the circuit board assembly 200 is locked to the mounting bracket 300, thereby preventing the circuit board assembly 200 from warping and deformation during locking.

[0083] Each fixed edge 222 of the adapter plate 220 is stacked with a mounting ear 322 of the front plate 320 along the Z-axis. The fixing holes 226 of the fixed edge 222 are coaxially arranged with the mounting holes 3221 of the mounting ears 322. A locking member C is inserted through the fixing holes 226 and the mounting holes 3221 and is locked to the self-clinching nut on the mounting ears 322, thereby removably connecting the circuit board assembly 200 to the mounting bracket 300.

[0084] Second embodiment:

[0085] See also Figure 11 , Figure 11 for Figure 2 FIG. 1 is a partial structural diagram of a second embodiment of a housing 100 .

[0086] In this embodiment, the same contents as those in the first embodiment are not repeated here. The difference from the first embodiment is that, in this embodiment, the holding portion 60 is spaced apart from the reinforcing rib 43 along the X-axis direction. The holding portion 60 and the reinforcing rib 43 form a split structure. At the same time, along the Y-axis direction, the holding portion 60 can be connected to the first plate body 41. Alternatively, the holding portion 60 can be spaced apart from the first plate body 41. It can be understood that the holding portion 60 can be integrally formed with the first plate body 41, or the holding portion 60 can be separately formed from the first plate body 41. This embodiment does not impose any restrictions on this.

[0087] In the related art, the circuit board is locked to the side of the battery, or the circuit board is locked to the panel. However, when installing or removing the circuit board, it is necessary to remove the panel and then install or remove the circuit board. The operation is complicated and difficult, which reduces the convenience of installing or removing the circuit board in the power supply product. In the embodiment of the present application, an adapter plate 220 is added, and the circuit board 210 is detachably connected to the adapter plate 220 through a fastener D to form a circuit board assembly 200. A fixed edge 222 is provided on the adapter plate body 221 of the adapter plate 220. The fixed edge 222 is perpendicular to the extension direction of the adapter plate body 221, and the fixed edge 222 is detachably connected to the mounting ear 322 of the mounting bracket 300. The circuit board assembly 200 is locked to the outer side surface 311 of the bracket body 310, which not only avoids the circuit board 210 from being locked to the base plate 10 and occupying most of the space inside the power supply device 1000, which is beneficial to reducing the volume of the power supply device 1000 and improving the volume energy density of the power supply device 1000, but also facilitates the circuit board assembly 200 to directly disassemble or install the adapter plate 220 and the bracket body 310 from the first opening 102, so as to realize taking the circuit board assembly 200 out of or putting it into the shell 100, thereby eliminating the need to remove the front panel 21 to repair the circuit board 210, thereby improving the convenience of disassembling or installing the circuit board 210.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, according to the idea of ​​the present application, there may be changes in the specific embodiments and application scope.
