Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and 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.

[0046] In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise specified precisely.

[0047] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0048] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0049] With the rapid development of new energy electric vehicles, consumers' demand for them is increasing, and they are paying close attention to issues such as safety. As a crucial component of new energy electric vehicles, the battery pack not only affects their performance and safety but also directly impacts their market competitiveness and sustainable development.

[0050] As mentioned in the background section, battery packs in related technologies have low safety and are prone to damage after collision. The reason for this problem is that the battery pack of a vehicle is usually located at the bottom of the vehicle. During vehicle operation, the bottom of the battery pack is easily damaged by flying debris such as mud, sand, or flying stones. In order to improve the safety of the battery pack, a protective coating is usually applied to the bottom of the battery pack.

[0051] In related technologies, the protective coating is usually made of polyvinyl chloride (PVC), which has abrasion resistance and a certain degree of impact resistance. However, when the protective coating is hit by mud, sand, or flying stones, it can be damaged and corroded, exposing the battery pack and easily failing over long-term use. Furthermore, the driving conditions of vehicles are unpredictable. When encountering road bumps, such as tree stumps or curbs, these bumps can directly impact the battery pack, damaging the protective coating or even squeezing the battery pack, leading to deformation and damage.

[0052] To address the aforementioned technical issues, this application provides a battery assembly and a vehicle. In this solution, the battery assembly includes a battery pack, a protective plate, and a crash beam. The battery pack is mounted at the bottom of the vehicle frame. A first end of the crash beam connects to the vehicle frame, and a second end extends downwards. The protective plate connects to the second end of the crash beam, with at least a portion of the protective plate located below the battery pack. The protective plate, positioned below the battery pack, directly shields against mud, sand, and flying stones, preventing direct impact on the battery pack surface. The crash beam extends downwards from the vehicle frame and connects with the protective plate to form a rigid support structure. When the vehicle is in motion, the impact force from ground protrusions is preferentially absorbed by the crash beam and protective plate and distributed through the vehicle frame, reducing the risk of direct compression or deformation of the battery pack and improving its safety.

[0053] It should be noted that, Figures 1 to 6 This diagram illustrates a simplified schematic of the battery pack and various components within the vehicle. The specific structures of the battery pack and other components in the vehicle are not limited to these examples. Figures 1 to 6 of examples.

[0054] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of this application provides a battery assembly including a battery pack 100, a protective plate 200, and a crash beam 300; the battery pack 100 is used to be installed at the bottom of the vehicle frame 10. The battery pack 100 is the power source for the vehicle, and this embodiment of the application does not limit the structure of the battery pack 100.

[0056] The first end of the anti-collision beam 300 is used to connect to the vehicle frame 10, and the second end of the anti-collision beam 300 extends downward; the protective plate 200 is connected to the second end of the anti-collision beam 300, and at least a portion of the protective plate 200 is located below the battery pack 100.

[0057] It should be noted that the frame 10 is a frame structure that spans the front and rear axles of the vehicle, and typically includes two longitudinal beams and several transverse beams. The frame 10 has sufficient strength and rigidity to withstand the load of the vehicle and the impact transmitted from the wheels. This application does not limit the specific structure of the frame 10.

[0058] In the above embodiment, the protective plate 200 is located below the battery pack 100, directly shielding it from mud, sand, flying stones, and other debris, preventing them from directly impacting the lower surface of the battery pack 100. Compared to the use of protective coatings in related technologies, this significantly reduces the risk of damage to the battery pack 100. The anti-collision beam 300 extends downward from the frame 10 and connects with the protective plate 200 to form a rigid support structure. When the vehicle travels on uneven roads, the impact force of ground protrusions can be preferentially absorbed by the anti-collision beam 300 and the protective plate 200, and dispersed through the frame 10, reducing the risk of direct compression or deformation of the battery pack 100.

[0059] The anti-collision beam 300 transmits the impact force of a collision protrusion to the frame 10, while the protective plate 200 covers the bottom area of ​​the battery pack 100, directly providing physical isolation. The protective plate 200 can be a steel plate or a sheet metal stamping part, possessing high hardness and strength. The combination of the anti-collision beam 300 and the protective plate 200 enhances the impact resistance of the battery pack 100, thereby improving its safety.

[0060] In one possible implementation, refer to Figure 2 As shown, the protective plate 200 includes a main body 210 and an extension 220.

[0061] The main body 210 is located below the battery pack 100, and the extension 220 is disposed on the main body 210, with the end of the extension 220 away from the main body 210 inclined upward. It should be noted that the projection of the battery pack 100 toward the main body 210 is located inside the main body 210, or in other words, the main body 210 can completely cover the bottom surface of the battery pack 100 to improve the safety of the bottom surface of the battery pack 100.

[0062] The extension 220 is integrally formed with the main body 210, which can further improve the structural strength of the protective plate 200.

[0063] In the above embodiments, the upward tilting structure of the extension 220 can further shield the outer side and bottom regions of the battery pack 100, increase the protective area of ​​the battery pack 100, further reduce the risk of splashing objects intruding, and improve the comprehensiveness of protection.

[0064] Furthermore, when impacted by ground protrusions or flying debris, the inclined structure of the extension 220 can decompose the vertical impact force into a sliding force along the inclined surface of the extension 220 and a partial vertical buffering force, thereby reducing the direct pressure on the main body 210 of the protective plate 200. The inclined structure of the extension 220 can guide flying debris to slide off the inclined surface instead of directly impacting the bottom of the battery pack 100 vertically, thus providing a certain guiding effect on the flying debris and reducing the risk of wear and corrosion to the battery pack 100 or its main body.

[0065] In a specific implementation, there are multiple extensions 220, including a first extension 220a and a second extension 220b.

[0066] The first extension 220a is located on the front side of the main body 210, and the second extension 220b is located on the rear side of the main body 210. It should be noted that the front and rear sides of the main body 210 are parallel to the vehicle's direction of travel. The width of the first extension 220a is the same as the width of the main body 210, and the width of the second extension 220b is the same as the width of the main body 210.

[0067] In the above embodiment, by providing a first extension 220a and a second extension 220b, located on the front and rear sides of the main body 210 respectively, the battery pack 100 can be covered in the front and rear areas along the vehicle's driving direction. This allows for targeted protection against splashes from different directions. The first extension 220a on the front side can block splashes of sand, mud, etc., caused by tires running over or ejecting them, preventing direct impact on the front of the battery pack 100. The second extension 220b on the rear side can protect the battery pack 100 from impacts from road protrusions or splashes kicked up by vehicles behind. This effectively protects against impacts from both the front and rear of the vehicle, safeguarding the battery pack 100 during forward or reverse movement.

[0068] Furthermore, during vehicle operation, the battery pack 100 may experience displacement or vibration due to bumps. The arrangement of the first extension 220a and the second extension 220b can limit the displacement of the battery pack 100 and enhance system stability.

[0069] Alternatively, in another implementation, the extension 220 further includes a third extension (not shown) and a fourth extension (not shown), which are respectively disposed on both sides of the main body 210 along its length, with the ends of the third and fourth extensions facing away from the main body 210 inclined upwards. This further protects against splashes from both sides along the length of the battery pack 100, thereby further improving the safety of the battery pack 100.

[0070] In one possible implementation, to improve the stability of the battery pack 100, refer to Figure 3As shown, the battery pack 100 has multiple connectors 400, which are disposed on both sides of the battery pack 100 in the front-rear direction. The battery pack 100 can be connected to the vehicle frame 10 through the connectors 400. The connectors 400 can be plate-shaped or rod-shaped. In related technologies, the battery pack 100 has a shell. One end of the connector 400 is bolted to the shell of the battery pack 100, and the other end of the connector 400 is bolted to the vehicle frame 10. This significantly improves the stability of the battery pack 100, and the bolted connection between the battery pack 100 and the vehicle frame 10 facilitates future maintenance and replacement of the battery pack 100. The presence of the same number of connectors 400 on both sides of the battery pack 100 in the front-rear direction ensures uniform stress distribution on the battery pack 100, reducing the risk of displacement or vibration of the battery pack 100.

[0071] In one possible implementation, refer to Figure 2 As shown, the protective plate 200 is provided with at least one first reinforcing part 230, which is disposed between the main body 210 and the extension 220. The first end of the first reinforcing part 230 is connected to the extension 220, and the second end of the first reinforcing part 230 is connected to the main body 210. Specifically, multiple first reinforcing parts 230 are provided, and these multiple first reinforcing parts 230 are arranged at intervals along the width direction of the main body 210. The first reinforcing parts 230 serve as structural ribs. By adding structural ribs, the first reinforcing parts 230 effectively disperse impact force, preventing tearing or deformation at the connection between the extension 220 and the main body 210 caused by impacts from flying debris or ground protrusions, thus ensuring the overall structural integrity of the protective plate 200.

[0072] The main body 210 is provided with at least one second reinforcing part 240, which extends along the length direction of the main body 210. Multiple second reinforcing parts 240 are provided, and they are arranged at intervals along the width direction of the main body 210. The second reinforcing part 240 can be a structural rib or a reinforcing groove formed on the side of the main body 210 opposite to the battery pack 100.

[0073] In the above embodiments, the second reinforcing part 240, by providing structural ribs or bars along its length, significantly improves the bending and compressive resistance of the main body 210, preventing the battery pack 100 from undergoing overall deformation when subjected to side impacts or bottom compression, thereby indirectly protecting the battery pack 100. The first reinforcing part 230 can balance the oblique impact force transmitted by the inclined surface of the extension part 220, while the second reinforcing part 240 reduces the bending stress of the main body 210 through longitudinal support. This reduces the risk of material fatigue or crack propagation caused by repeated impacts.

[0074] In one possible implementation, the number of anti-collision beams 300 is set to multiple, including a first anti-collision beam 300a and a second anti-collision beam 300b.

[0075] The first anti-collision beam 300a is located on the front side of the battery pack 100 and is connected to the first end of the protective plate 200. Specifically, the first anti-collision beam 300a is connected to the end of the first extension 220a away from the main body 210. The second anti-collision beam 300b is located on the rear side of the battery pack 100 and is connected to the second end of the protective plate 200. Specifically, the second anti-collision beam 300b is connected to the end of the second extension 220b away from the main body 210.

[0076] In the above configuration, the first anti-collision beam 300a is located at the front of the battery pack 100, and the second anti-collision beam 300b is located at the rear of the battery pack 100, forming a symmetrical front-to-back protection system. This system can simultaneously resist impacts from both the front and rear of the vehicle, avoiding localized stress concentration caused by unidirectional force. The first anti-collision beam 300a, the protective plate 200, and the second anti-collision beam 300b are sequentially connected to form a frame-like protective structure, protecting the battery pack 100 within this structure and significantly improving its safety. When the vehicle is moving forward, if it encounters a road protrusion, the protrusion will first contact and collide with the first anti-collision beam 300a. The first anti-collision beam 300a can absorb some of the impact force, preventing the protrusion from directly colliding with the battery pack 100. Similarly, the second anti-collision beam 300b can first contact and collide with the protrusion during the vehicle's reversing motion, further protecting the battery pack 100.

[0077] In a specific implementation, the battery assembly also includes a mounting base 500, which is used to mount the battery on the frame 10.

[0078] The first end of the anti-collision beam 300 is connected to the mounting base 500.

[0079] The first anti-collision beam 300a and the second anti-collision beam 300b have the same length and are arranged in parallel.

[0080] In the above embodiment, the first end of the anti-collision beam 300 is connected to the vehicle frame 10 via the mounting base 500, rather than being directly fixed to the vehicle frame 10. This avoids loosening of the connection due to deformation of the vehicle frame 10 or uneven mounting surface, ensuring that the anti-collision beam 300 can stably transmit force to the vehicle frame 10 when subjected to impact, reducing the risk of vibration transmission and connection failure.

[0081] Furthermore, by setting up the mounting base 500, which is an independent module that can be pre-installed on the frame 10, the assembly process of the anti-collision beam 300 is simplified, while ensuring the consistency of the connection position and reducing the impact of assembly errors on the protective performance.

[0082] Furthermore, the first anti-collision beam 300a and the second anti-collision beam 300b are of the same length and are arranged parallel to each other, so that the impact force in the front and rear directions can be symmetrically transmitted to the frame 10, avoiding torque imbalance or stress concentration on one side due to the difference in length. This prevents either the first anti-collision beam 300a or the second anti-collision beam 300b from breaking. In addition, the anti-collision beam 300 is connected to the frame 10 through the mounting base 500, and can be disassembled or replaced individually, reducing later maintenance costs and time.

[0083] In one possible implementation, the mounting base 500 is provided with an adjusting member 510. When the adjusting member 510 is in a first state, the first end of the anti-collision beam 300 is fixedly connected to the mounting base 500.

[0084] When the adjusting member 510 is in the second state, the first end of the anti-collision beam 300 is rotatably connected to the mounting base 500.

[0085] In the above embodiments, when the adjusting member 510 is in the first state, the anti-collision beam 300 forms a rigid connection with the frame 10 through the mounting base 500, which can effectively transmit impact force and ensure the stability of the protective structure. At this time, the anti-collision beam 300 acts as a "rigid support" and can directly transmit the impact force to the frame 10, preventing the battery pack 100 from bearing direct pressure. When the adjusting member 510 is in the second state, the anti-collision beam 300 can rotate slightly relative to the mounting base 500 to form a flexible connection. This is suitable for scenarios such as bumpy roads or low-speed passage over protrusions, where rotation buffers impact energy and prevents rigid collisions from damaging the battery pack 100 and the frame 10. In the event of a minor impact, the rotation of the anti-collision beam 300 can absorb some energy, reducing the load transmitted to the battery pack 100.

[0086] Reference Figure 4 and Figure 5 As shown, the anti-collision beam 300 includes a horizontal portion 310, a vertical portion 320, and a connecting portion 330. The connecting portion 330 is connected to the horizontal portion 310 via the vertical portion 320. The extension direction of the horizontal portion 310 is consistent with the width direction of the battery pack 100, and the horizontal portion 310 is horizontally positioned. The vertical portion 320 extends along the height direction of the battery pack 100. The connecting portion 330 can be horizontally positioned and is connected to the mounting base 500. The horizontal portion 310 and the vertical portion 320, as well as the connecting portion 330 and the vertical portion 320, are smoothly connected; or the horizontal portion 310, the vertical portion 320, and the connecting portion 330 are integrally formed. The horizontal portion 310 is provided with multiple connecting ears 311, which are spaced apart along the length direction of the horizontal portion 310. The horizontal portion 310 is connected to the extension portion 220 via the connecting ears 311. The transverse portion 310 forms the second end of the anti-collision beam 300, and the connecting portion 330 forms the first end of the anti-collision beam 300.

[0087] Both ends of the horizontal portion 310 are connected to the connecting portion 330 via the vertical portion 320. There are two mounting bases 500 corresponding to the connecting portions 330, and each connecting portion 330 is connected to the frame 10 via the corresponding mounting base 500.

[0088] In one possible implementation, refer to Figure 6 As shown, the mounting base 500 includes a first clamping member 520 and a second clamping member 530.

[0089] The first end of the anti-collision beam 300 is located between the first clamping member 520 and the second clamping member 530, that is, the connecting part 330 is located between the first clamping member 520 and the second clamping member 530. Alternatively, it can be understood that the mounting base 500 has a connecting hole 501, and the connecting part 330 is inserted into the connecting hole 501.

[0090] The adjusting member 510 connects the first clamping member 520 and the second clamping member 530 to move the first clamping member 520 and the second clamping member 530 closer to or further apart from each other.

[0091] When the adjusting member 510 is in the first state, the adjusting member 510 drives the first clamping member 520 and the second clamping member 530 to move closer to each other so as to clamp the first end of the anti-collision beam 300.

[0092] When the adjusting member 510 is in the second state, the adjusting member 510 drives the first clamping member 520 and the second clamping member 530 to move away from each other, so that the first end of the anti-collision beam 300 can rotate between the first clamping member 520 and the second clamping member 530.

[0093] Here, the first clamping member 520 and the second clamping member 530 are integrally formed, and the integrally formed first clamping member 520 and the second clamping member 530 have a certain elastic deformation capacity, so as to facilitate the adjusting member 510 to move the first clamping member 520 and the second clamping member 530 closer to each other or further away from each other. The first clamping member 520 and the second clamping member 530 are both fixedly connected to the frame 10 by bolts. Of course, the first clamping member 520 and the second clamping member 530 can also be connected to the frame 10 by welding.

[0094] The adjusting member 510 can be a bolt. By adjusting the depth of the bolt screwed into the first clamping member 520 or the second clamping member 530, the gap between the first clamping member 520 and the second clamping member 530 can be adjusted. Specifically, when the adjusting member 510 is tightened, the first clamping member 520 and the second clamping member 530 move closer to each other, so that the first clamping member 520 and the second clamping member 530 clamp the connecting part 330 in the connecting hole 501, thereby securing the anti-collision beam 300.

[0095] When the adjusting member 510 is loosened, the first clamping member 520 and the second clamping member 530 move away from each other, and the connecting part 330 can rotate within the connecting hole 501. This allows for a small rotation of the anti-collision beam 300.

[0096] In the above embodiment, the first clamping member 520 and the second clamping member 530 are linked by the adjusting member 510, which can symmetrically clamp the anti-collision beam 300 from both sides to form a mechanical locking structure. This can distribute the clamping force more evenly, preventing the anti-collision beam 300 from shifting or loosening due to force on one side, and significantly improving the stability of the connection. The adjusting member 510 can switch between the "clamping" and "releasing" states of the clamping members through simple operation. For example, when it is necessary to fix the anti-collision beam 300, simply switch the adjusting member 510 to the first state; when flexible buffering is needed, switch to the second state, without the need for complex tools or disassembly of the structure.

[0097] In one possible implementation, this application also provides a vehicle, including a vehicle body and the aforementioned battery assembly. The vehicle body has a frame 10, and the battery assembly can be mounted on the vehicle body via the frame 10. The specific structure of the battery assembly has been described above and will not be repeated here. The vehicle body can be a pure electric passenger vehicle, a plug-in hybrid passenger vehicle, an electric commercial vehicle, an electric light truck, etc. This application does not limit the specific type of vehicle body. By setting the aforementioned battery assembly, the risk of impact from splashing objects, protrusions, and collisions to the battery pack 100 can be effectively resisted, thereby improving the overall vehicle safety.

[0098] The implementation principle of a battery assembly and vehicle according to an embodiment of this application is as follows: the battery assembly includes a battery pack 100, a protective plate 200, and a crash beam 300; the battery pack 100 is disposed at the bottom of a vehicle frame 10; the first end of the crash beam 300 is connected to the vehicle frame 10, and the second end of the crash beam 300 extends downward; the protective plate 200 is connected to the second end of the crash beam 300, and at least a portion of the protective plate 200 is located below the battery pack 100. The protective plate 200, located below the battery pack 100, can directly shield against mud, sand, flying stones, and other splashing objects, preventing direct impact on the surface of the battery pack 100. The crash beam 300 extends downward from the vehicle frame 10 and connects with the protective plate 200 to form a rigid support structure. When the vehicle is in motion, the impact force of ground protrusions can be preferentially absorbed by the crash beam 300 and the protective plate 200, and dispersed and transmitted through the vehicle frame 10, reducing the risk of direct compression or deformation of the battery pack 100 and improving the safety of the battery pack 100.
