Description

Technical Field

[0001] This application relates to the field of battery packs, and more specifically, to a battery pack housing, a battery pack, and a vehicle. Background Technology

[0002] As the most expensive component in commercial vehicles, the battery's cycle life directly determines the vehicle's lifespan and economic benefits. To achieve "vehicle and battery lifespan in sync," meaning the battery lifespan is synchronized with the vehicle's lifespan and to avoid the cost of replacing the battery midway through the journey, the battery cells need to be upgraded to achieve a longer cycle life.

[0003] However, the increased size of cells with higher cycle life means that a single module in a battery pack typically contains multiple cells, thus increasing the module size. This larger module encroaches on the area originally used for installing electrical components and the installation space. For example, electrical components that were originally distributed in the front, middle, and rear of the battery pack housing now need to be integrated into the front due to the increased space occupied by the larger modules. A single Z-shaped electrical mounting plate in the front of the battery pack housing cannot meet the installation space requirements of all electrical components, necessitating additional space. Furthermore, the dense arrangement of electrical components causes the bolts at the bottom of the traditional Z-shaped electrical mounting plate to be obstructed by other components, leading to installation difficulties. If these problems cannot be solved, the length of the battery pack housing needs to be increased, requiring corresponding adjustments to the overall vehicle layout, increasing costs, and extending the development cycle. Utility Model Content

[0004] The purpose of this application is to provide a battery pack housing, a battery pack, and a vehicle to alleviate the technical problem in the prior art where upgrading battery cells leads to difficulties in installing electrical components.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: In the first aspect, the battery pack housing provided by this utility model includes a housing body, an adapter bracket, and an electrical mounting plate; The first side wall of the housing body has a first mounting position for installing a connector and a second mounting position for installing a water tap adapter. The adapter bracket is installed on the first side wall, and the adapter bracket is horizontally spaced from the first mounting position and located above the second mounting position. The electrical mounting plate is disposed opposite to the first sidewall and is detachably connected to the adapter bracket; the sidewall of the electrical mounting plate opposite to the first sidewall is used to install electrical components.

[0006] The battery pack enclosure utilizes the inner side wall of the front panel of the enclosure body as the installation location for electrical components. It makes full use of the space on the side of the connector inside the front panel and above the water tap adapter, which avoids the problem of needing to expand the enclosure body to accommodate electrical components and improves the space utilization of the battery pack.

[0007] Furthermore, the adapter bracket is welded to the first sidewall, thus enabling the adapter bracket to be installed on the first sidewall and improving the installation stability of the adapter bracket.

[0008] Furthermore, the adapter bracket includes a first connecting part and a second connecting part, wherein the first connecting part and the second connecting part are connected at an angle; The first connecting part is fitted and welded to the first sidewall, and the second connecting part is detachably connected to the electrical mounting plate; thus, the adapter bracket can be connected to both the first sidewall and the electrical mounting plate simultaneously.

[0009] Furthermore, the second connecting part is connected to the electrical mounting plate via a first fastener; the structure is simple and easy to install.

[0010] Furthermore, the axis of the first fastener extends along the height direction of the housing body; The electrical mounting plate has a folded edge at the top, and the first fastener passes through the folded edge and the second connecting part; the operator can easily install the electrical mounting plate on the adapter bracket by horizontally rotating the first fastener located near the opening of the lower housing.

[0011] Furthermore, the bottom end of the electrical mounting plate is fitted with the bottom wall of the enclosure body; no bolt connection is required, avoiding the problem of the lower bolts being blocked by other components, which would make installation difficult for operators.

[0012] Furthermore, the bottom end of the electrical mounting plate is snapped or bonded to the bottom wall of the enclosure body; no bolt connection is required, making operation simple and enabling stable positioning.

[0013] Furthermore, the electrical mounting plate includes a mounting plate body and two extensions. The top end of the mounting plate body has the folded edge, and the bottom end is connected to the two extensions. The two extensions are limited and engaged with the bottom wall of the housing body, and the second mounting position is located between the two extensions; and a water tap adapter is avoided.

[0014] Furthermore, the axis of the first fastener is perpendicular to the height direction of the housing body; this facilitates operation and utilizes the space of the inner sidewall of the front panel of the housing body.

[0015] Furthermore, the battery pack housing includes a module electrical mounting plate; The housing body has a receiving cavity for carrying the module; the module electrical mounting plate is located on the side of the electrical mounting plate away from the first side wall, and its top end is used for detachable connection with the top end of the module, and its bottom end is limited to the bottom wall of the housing body. The module electrical mounting plate, located away from the sidewall of the module, is used to mount electrical components. The module electrical mounting plate is used to mount certain electrical parts within the electrical components.

[0016] Furthermore, the top of the module electrical mounting plate is provided with a bent portion, which fits against the top of the module and is connected by a second fastener. This allows the upper end of the module electrical mounting plate and the module to share the same second fastener for fixation.

[0017] Secondly, the battery pack provided by this utility model includes modules, connectors, water tap adapters, electrical components, and a battery pack housing as described in any of the above items; The module is installed within the receiving cavity of the battery pack housing. The connector is installed at a first mounting position within the battery pack housing, the water tap adapter is installed at a second mounting position within the battery pack housing, and the electrical components are mounted on the surface of the electrical mounting plate facing away from the housing body. The housing body serves to support the components inside each battery pack.

[0018] Furthermore, the electrical components include a first electrical box and a second electrical box, the first electrical box being mounted on the electrical mounting plate and the second electrical box being mounted on the module electrical mounting plate.

[0019] Thirdly, the vehicle provided by this utility model includes a battery pack as described in any of the above claims.

[0020] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows: The battery pack housing provided by this utility model includes a housing body, an adapter bracket, and an electrical mounting plate. The first side wall of the housing body has a first mounting position for mounting a connector, i.e., the connector in the battery pack is mounted at the first mounting position on the first side wall. The first side wall also has a second mounting position for mounting a water tap adapter, i.e., the water tap adapter in the battery pack is mounted at the second mounting position on the first side wall. The adapter bracket is mounted on the first side wall of the housing body and is spaced horizontally from the connector and spaced vertically from the water tap adapter to avoid obstructing the connector and water tap adapter. The horizontal direction refers to the direction perpendicular to the height of the housing body when the housing body is in its normal placement state, i.e., when the bottom wall of the housing body is horizontal. The adapter bracket being located above the second mounting position means that, in the normal placement state, the adapter bracket is located above the second mounting position along the height of the housing body. The electrical mounting plate is connected to the adapter bracket and is used to mount electrical components, thus enabling the electrical mounting plate with the mounted electrical components to be mounted on the first side wall of the housing body. Generally, connectors and water tap adapters are installed on the inside of the front panel of the battery pack body, meaning the first side wall is typically the inner side wall of the front panel. This battery pack enclosure utilizes the inner side wall of the front panel as the mounting location for electrical components, making full use of the space on the sides of the connectors and above the water tap adapters inside the front panel. This avoids the need to expand the enclosure body to accommodate the electrical components, thus improving the space utilization of the battery pack. Furthermore, the electrical mounting plate is detachably mounted on the adapter bracket, making installation simple and easy.

[0021] The battery pack enclosure utilizes the space on the first side wall of the enclosure body, the outside of the connector, and above the water tap adapter to arrange some electrical components, solving the problem that electrical components in the occupied space cannot be arranged after the module growth encroaches on the electrical installation space in the middle and rear.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] Example 1 As the most expensive component in commercial vehicles, the battery's cycle life directly determines the vehicle's lifespan and economic benefits. Current industry benchmarks have increased the cycle life from 3,000 to 5,000 or even 7,000 cycles, aiming for "vehicle-battery lifespan synchronization," meaning the battery's lifespan is synchronized with the vehicle's lifespan, avoiding the huge costs of mid-life battery replacements. Leading battery manufacturers are successively launching upgraded battery cells with higher cycle life, enabling battery pack manufacturers to launch upgraded battery pack products with higher cycle life without needing to undergo re-certification by the Ministry of Industry and Information Technology (MIIT), achieving a "seamless" switch between old and new products with the same capacity and appearance. However, these upgraded battery cells with higher cycle life are generally thicker than their predecessors. For example, one leading manufacturer's upgraded cell model is 2.4mm thicker, and another model is 1.7mm thicker, generally an increase of about 5%. A typical module contains a dozen to twenty battery cells, increasing the overall module length by approximately 30-50mm. This increased module length encroaches on the area originally used for installing electrical components and reduces installation space, leading to design challenges. For example, electrical components originally located at the front, middle, and rear of the module must be integrated into the front due to the increased space occupied by the module. Furthermore, the existing electrical mounting plate at the front of the module may not provide sufficient space for all components, requiring additional space for a second plate. The dense arrangement of electrical components also causes the bolts on the lower part of the traditional Z-shaped electrical mounting plate to be obstructed by other components, making installation difficult. If these challenges cannot be resolved, it becomes necessary to increase the enclosure length, leading to adjustments in the overall vehicle layout and the need for new permits, significantly increasing costs and development time.

[0029] In view of this, see Figure 1 The battery pack housing provided in this embodiment includes a housing body 100, an adapter bracket 200, and an electrical mounting plate 300. The first side wall of the housing body 100 has a first mounting position for mounting a connector 610 and a second mounting position for mounting a water tap adapter 620. The adapter bracket 200 is mounted on the first side wall, and the adapter bracket 200 is horizontally spaced from the first mounting position and located above the second mounting position. The electrical mounting plate 300 is disposed opposite to the first side wall and is detachably connected to the adapter bracket 200. The side wall of the electrical mounting plate 300 away from the first side wall is used to mount electrical components 640.

[0030] Specifically, the housing body 100 includes a lower housing and an upper housing, with the upper housing covering the lower housing. The lower housing includes a front panel 110, a rear panel, a bottom plate 120, and two side panels. The front panel 110 and the rear panel are spaced apart from each other, and the two side panels are also spaced apart from each other. The two ends of the two side panels are perpendicularly connected to the front panel 110 and the rear panel, respectively. The bottom plate 120 is perpendicularly connected to the front panel 110, the rear panel, and the two side panels, forming a housing structure with an opening at the top. The first side wall refers to the inner side wall of the front panel 110, and the connector 610, the water tap adapter 620, and the adapter bracket 200 are all mounted on the front panel 110.

[0031] The first sidewall of the housing body 100 has a first mounting position for mounting the connector 610, i.e., the connector 610 in the battery pack is mounted at the first mounting position on the first sidewall; the first sidewall also has a second mounting position for mounting the water tap adapter 620, i.e., the water tap adapter 620 in the battery pack is mounted at the second mounting position on the first sidewall; the adapter bracket 200 is mounted on the first sidewall of the housing body 100 and is spaced apart from the connector 610 in the horizontal direction and from the water tap adapter 620 in the height direction of the housing body 100, so as to avoid the connector 610 and the water tap adapter 620. Here, the horizontal direction refers to the direction perpendicular to the height direction of the housing body 100 when the housing body 100 is in its normal placement state, i.e., when the bottom wall of the housing body 100 is horizontal; in this embodiment, if the first sidewall is the inner sidewall of the front panel 110, then the horizontal direction refers to the width direction of the front panel 110. The adapter bracket 200 being located above the second mounting position means that, when the enclosure body 100 is in its normal placement state, the adapter bracket 200 is positioned above the second mounting position along the height direction of the enclosure body 100. The electrical mounting plate 300 is connected to the adapter bracket 200 and is used to mount the electrical component 640, allowing the electrical mounting plate 300, with the electrical component 640 mounted, to be installed on the first side wall of the enclosure body 100. This battery pack enclosure utilizes the inner side wall of the front panel 110 of the enclosure body 100 as the mounting location for the electrical component 640, making full use of the space on the side of the connector 610 inside the front panel 110 and above the water tap adapter 620. This avoids the need for the enclosure body 100 to expand its space to accommodate the electrical component 640, improving the battery pack's space utilization rate. Furthermore, the electrical mounting plate 300 is detachably mounted to the adapter bracket 200, making installation simple and easy. The battery pack enclosure utilizes the space of the first side wall of the enclosure body 100, the outside of the connector 610, and the space above the water tap adapter 620 to arrange some electrical components 640, thus solving the problem that electrical components in the occupied space cannot be arranged after the module 630 grows and occupies the electrical installation space in the middle and rear.

[0032] The structure and shape of the adapter bracket 200 are described in detail below: In the optional solution provided by this utility model embodiment, the adapter bracket 200 is welded to the first side wall.

[0033] Specifically, the adapter bracket 200 has a surface that fits against the first sidewall and is welded to the first sidewall, thereby increasing the contact area between the adapter bracket 200 and the first sidewall.

[0034] The adapter bracket 200 is welded to the first side wall, so that the adapter bracket 200 can be installed on the first side wall, and the installation stability of the adapter bracket 200 is improved.

[0035] In the optional solution provided by this utility model embodiment, the adapter bracket 200 includes a first connecting part 210 and a second connecting part 220, the first connecting part 210 and the second connecting part 220 are connected at an angle; the first connecting part 210 is fitted and welded to the first side wall, and the second connecting part 220 is detachably connected to the electrical mounting plate 300.

[0036] Specifically, both the first connecting portion 210 and the second connecting portion 220 are flat. The first connecting portion 210 has the aforementioned surface that fits against the first sidewall for welding to the first sidewall. The second connecting portion 220 is bent away from the first sidewall for connection to the electrical mounting plate.

[0037] The adapter bracket 200 includes a first connecting part 210 and a second connecting part 220 connected at an angle, so that the adapter bracket 200 can be connected to the first side wall and the electrical mounting plate 300 at the same time.

[0038] In the optional embodiment of this utility model, the second connecting part 220 is connected to the electrical mounting plate 300 by the first fastener 510.

[0039] Specifically, the first fastener 510 includes a bolt and a nut. The bolt passes through the electrical mounting plate and the second connecting part 220 and is threadedly connected to the nut, so that the electrical mounting plate can be detachably installed on the adapter bracket 200.

[0040] As a first implementation method, see Figure 1 and Figure 2 The axis of the first fastener 510 extends along the height direction of the housing body 100; the top of the electrical mounting plate 300 is provided with a folded edge 320, through which the first fastener 510 passes.

[0041] Specifically, the adapter bracket 200 is L-shaped, with two branches: a first connecting portion 210 and a second connecting portion 220, which are perpendicular to each other. The first connecting portion 210 fits against the first sidewall, and the second connecting portion 220 is bent away from the first sidewall. Both the folded edge 320 and the second connecting portion 220 are provided with mounting holes, the axis of which extends along the height direction of the housing body 100. Preferably, a nut is riveted or back-welded to the lower part of the second connecting portion 220, so that the bolt passes through the folded edge 320 of the electrical mounting plate first and then through the second connecting portion 220, thereby positioning the folded edge 320 above the second connecting portion 220 and allowing the second connecting portion 220 to support the folded edge 320. Furthermore, there are two adapter brackets 200, which are spaced apart in the horizontal direction and are both located on the same side of the first mounting position. Correspondingly, the top left and right sides of the electrical mounting plate 300 are bent away from the first sidewall to form two folded edges 320. The two folded edges 320 are connected to the two adapter brackets 200 one by one through the first fasteners 510.

[0042] The top edge 320 of the electrical mounting plate 300 is connected to the adapter bracket 200 by the first fastener 510, so that the axis of the first fastener 510 extends along the height direction of the housing body 100. This allows the operator to horizontally rotate the first fastener 510 located near the lower housing opening to install the electrical mounting plate on the adapter bracket 200, which is convenient to operate.

[0043] In the optional solution provided by this utility model embodiment, the bottom end of the electrical mounting plate 300 is limited and matched with the bottom wall of the enclosure body 100.

[0044] Specifically, the electrical component 640 is bolted to the surface of the electrical mounting plate 300 opposite to the first sidewall.

[0045] The bottom end of the electrical mounting plate 300 is matched with the bottom wall of the enclosure body 100, eliminating the need for bolt connection and avoiding the problem of the lower bolts being blocked by other components, which would make installation difficult for operators.

[0046] In the optional solution provided by this utility model embodiment, the bottom end of the electrical mounting plate 300 is bonded to the bottom wall of the enclosure body 100.

[0047] Specifically, two spaced first fixing blocks are installed on the base plate 120 of the enclosure body 100, forming a first fixing groove 130 between the two first fixing blocks. The bottom end of the electrical mounting plate 300 is inserted into the first fixing groove 130, and structural adhesive is used to fill the gap between the electrical mounting plate 300 and the side wall of the first fixing groove 130 to fix the bottom end of the electrical mounting plate 300. The electrical mounting plate 300 rests against the side wall of the first fixing block near the first side wall, using the side wall of the first fixing block for positioning. Preferably, the first fixing block is welded to the base plate 120; the first fixing groove 130 is rectangular, and the first electrical box 641 of the electrical assembly 640 is installed on the electrical mounting plate 300. The first electrical box 641 is configured as a CAN (Controller Area Network) electrical box.

[0048] The bottom end of the electrical mounting plate 300 is bonded to the bottom wall of the enclosure body 100 without the need for bolt connection, which is simple to operate and can achieve stable positioning.

[0049] Alternatively, the bottom end of the electrical mounting plate 300 can be snapped into the bottom wall of the enclosure body 100.

[0050] Specifically, the bottom end of the electrical mounting plate 300 is connected to the bottom wall of the enclosure body 100 using a slot and buckle structure, which provides strong maintainability and high installation accuracy.

[0051] In the optional solution provided by this utility model embodiment, the electrical mounting plate 300 includes a mounting plate body 310 and two extensions 330. The top end of the mounting plate body 310 has a folded edge 320, and the bottom end is connected to the two extensions 330. The two extensions 330 are limited and cooperate with the bottom wall of the housing body 100, and the second mounting position is located between the two extensions 330.

[0052] Specifically, two extension plates extend downwards from the lower part of the mounting plate body 310, with a gap in the middle of the extension plates to avoid the water nozzle adapter. Furthermore, the mounting plate body 310, the folded edge 320, and the two extensions 330 are all integrally formed, utilizing sheet metal bent into corresponding parts. It is worth noting that when the adapter bracket 200 adopts the first embodiment, the electrical components 640 can be installed after the module 630 is placed in the enclosure.

[0053] The two extensions 330 are matched with the bottom wall limit, and the gap in the middle is used to avoid the water tap adapter, so as to prevent the electrical mounting plate 300 from affecting the water tap adapter. By utilizing the space on the inner wall of the front panel 110 of the lower housing, the outer side of the connector 610, and above the water tap adapter 620, some smaller electrical components can be arranged, solving the problem that the electrical components in the encroached space have nowhere to be arranged after the module 630 grows and encroaches on the electrical installation space in the middle and rear. The electrical component mounting plate installed on the front panel 110 solves the problem that the mounting space of the mounting plates installed on the module 630 and the lower housing is insufficient to meet the installation of all electrical components 640. The electrical mounting plate 300 installed on the front panel 110 is fixed with bolts at the top and inserted into the first fixing groove 130 at the bottom. The inner wall of the first fixing groove 130 is used for limiting and the structural adhesive is used for fixing. The structure is simple, with few parts and small space occupation. It solves the problem that the lower mounting bolt hole positions of the traditional Z-shaped mounting plate need to occupy a certain space, and it is impossible to leave the installation space required for the mounting base, bolts and other components under dense electrical component arrangement.

[0054] As a second implementation method, see Figures 4 to 7 The axis of the first fastener 510 is perpendicular to the height direction of the housing body 100.

[0055] Specifically, the adapter bracket 200 has a square frame structure, with the first connecting part 210 in the middle welded to the first side wall. Multiple second connecting parts 220 are provided, with each second connecting part 220 connected to the top of the first connecting part 210, and the second connecting parts 220 are L-shaped. The short side of the second connecting part 220 is perpendicular to the first connecting part 210, and the long side of the second connecting part 220 is parallel to and spaced apart from the first side wall. The first fastener 510 passes through the electrical mounting plate 300 and the long side of the second connecting part 220 and is threadedly connected to a nut. The bottom end of the first connecting part 210 is connected to the second connecting part 220. The second connecting part 220 installed at the bottom of the first connecting part 210 has the same shape as the second connecting part 220 installed at the top of the first connecting part 210, and will not be described further. Furthermore, the second connecting portion 220 installed at the bottom of the first connecting portion 210 is disposed opposite to the second connecting portion 220 installed at the top of the first connecting portion 210, and is located on the same side of the first connecting portion 210; the second connecting portion 220 is installed in the middle of the other side of the first connecting portion 210. It is worth noting that, in the second embodiment, the electrical component 640 is pre-installed before the module 630 is placed in the box, and the nut in the first fastener 510 is set as a riveted thin nut.

[0056] When the axis of the first fastener 510 is perpendicular to the height direction of the housing body 100, the electrical components 640 can be pre-installed, which is convenient to operate and has a simple structure.

[0057] The following details the other structural features of the battery pack housing: In the optional solutions provided by the embodiments of this utility model, see Figure 1 and Figure 3 The battery pack housing includes a module electrical mounting plate 400; the housing body 100 has a receiving cavity for carrying the module 630; the module electrical mounting plate 400 is located on the side of the electrical mounting plate 300 away from the first side wall, and its top end is used for detachable connection with the top end of the module 630, and its bottom end is limited to the bottom wall of the housing body 100; the side wall of the module electrical mounting plate 400 away from the module 630 is used to install electrical components 640.

[0058] Specifically, the front panel 110, rear panel, bottom plate 120, and two side panels of the lower housing are interconnected to form a receiving cavity, in which the module 630 is installed. A gap is left between the module 630 and the front panel 110 for arranging electrical components 640, wherein the module electrical mounting plate 400 is located in the gap, with its top end connected to the top end of the module 630 and its bottom end mating with the bottom plate 120. The electrical mounting plate 300 is also located in the gap, and the electrical mounting plate 300 is connected to the inner side wall of the front panel 110, i.e., the first side wall, via an adapter bracket 200. Two spaced second fixing blocks are installed on the bottom plate 120 of the housing body 100, forming a second fixing groove 140 between the two second fixing blocks. The second fixing groove 140 is located on the side of the first fixing groove 130 away from the first side wall. The bottom end of the module electrical mounting plate 400 is inserted into the second fixing groove 140, and structural adhesive is used to fill the gap between the module electrical mounting plate 400 and the side wall of the second fixing groove 140 to fix the bottom end of the module electrical mounting plate 400. The module electrical mounting plate 400 rests against the side wall of the second fixing block away from the first side wall, using the side wall of the second fixing block for positioning. Preferably, the second fixing block is welded to the bottom plate 120. The second fixing groove 140 is configured as a U-shaped structure, extending to the two side plates of the lower housing for welding sealing; alternatively, the second fixing groove 140 is configured as a rectangular structure, its length matching the length of the module electrical mounting plate 400, eliminating the need for welding to the side plates.
