Description

Technical Field

[0001] This invention relates to the field of battery protection technology, and more specifically, to a battery protection assembly, a battery system, and a vehicle. Background Technology

[0002] In existing technologies, the battery packs of hybrid electric vehicles are typically located in the vehicle chassis. Their front end not only houses important electrical connectors (such as high-voltage interfaces and coolant line interfaces), but is also close to the engine compartment and exhaust system, resulting in a complex operating environment and multiple threats.

[0003] 1) Bottom collision threat: During vehicle operation, the vehicle may encounter protruding manhole covers, fallen bricks, or other hard obstacles on the road. These objects may cause direct impact or scraping to the bottom or front of the battery pack, resulting in deformation or cracking of the pack, or even causing short circuits or fires in the internal cells.

[0004] 2) Vulnerability of connectors: The various connectors at the front of the battery pack are relatively fragile. In the event of a frontal or bottom collision, they are easily damaged by squeezing or impact, resulting in power interruption or system failure.

[0005] Currently, most battery protection measures on the market are fragmented solutions. For example, some solutions focus on protecting the bottom of the battery, mainly addressing the issues of quick installation and sealing of the bottom protective plate; others focus on thermal isolation, using a heat insulation plate with an aluminum outer layer and an intermediate heat insulation layer to isolate heat from the exhaust system. However, these solutions lack comprehensive protection for the specific area at the front of the battery pack and cannot effectively address the complex risks faced by the front of the battery pack.

[0006] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

[0007] The main objective of this invention is to provide a battery protection assembly, a battery system, and a vehicle to solve the problem of insufficient front-end protection of battery packs in the prior art.

[0008] To achieve the above objectives, according to one aspect of the present invention, a battery protection assembly is provided, comprising: a protective body having a first battery connection portion and a vehicle body connection portion, the protective body being connected to a battery via the first battery connection portion and to a vehicle body via the vehicle body connection portion; and a connector protective cover located on one side of the protective body along its length and connected to the protective body, the connector protective cover having a second battery connection portion and being connected to the battery via the second battery connection portion; wherein, when the battery protection assembly is connected to the battery via the first battery connection portion and the second battery connection portion, the protective body shields the end face of the battery along the horizontal direction of the battery, a portion of the connector protective cover shields the battery connector along the horizontal direction of the battery, and another portion of the connector protective cover is located on the side of the battery connector closer to the ground and shields the battery connector along the height direction of the battery.

[0011] Furthermore, the edge of the second flange is also provided with a third flange, which extends toward the first side in the height direction of the battery protection assembly.

[0012] Furthermore, the battery protection assembly is provided with a plurality of first reinforcing ribs, which are spaced apart along the length of the battery protection assembly.

[0013] Furthermore, the connector protective cover includes: a protective cover body, which is located on one side of the protective body along its length and is connected to the protective body; a fourth flange is provided on the edge of the protective cover body along its height, which is folded towards the side where the battery is located; a second battery connection portion is provided on the fourth flange; and a heat insulation layer is provided on the side of the protective cover body away from the battery. When the protective body is connected to the battery, the protective cover body shields the battery along the horizontal direction of the battery, and the fourth flange is located on the side of the battery connector closest to the ground and shields the battery connector along the height direction of the battery.

[0014] Furthermore, a second reinforcing rib is provided on the protective cover body.

[0015] Furthermore, the first battery connection part includes a first connection hole, the body connection part includes a second connection hole, the second battery connection part includes a third connection hole, and a shock-absorbing sleeve is provided inside at least one of the first connection hole, the second connection hole, and the third connection hole.

[0016] According to another aspect of the present invention, a battery system is provided, the battery system having a battery protection assembly, the battery protection assembly being the aforementioned battery protection assembly.

[0017] According to another aspect of the present invention, a vehicle is provided, the vehicle having a battery system, the battery system being the battery system described above.

[0018] Applying the technical solution of this invention, the protective body is connected to the battery via a first battery connection part and simultaneously connected to the vehicle body via a body connection part, forming a stable structure. The connector protective cover is connected to the battery via a second battery connection part. The connector protective cover can partially shield the battery connector along the horizontal direction of the battery, while another part is located on the side of the battery connector closer to the ground, providing protection along the height direction of the battery. When the protective assembly is installed in place, the protective body effectively shields the end face of the battery along the horizontal direction, preventing frontal collisions from directly impacting the battery. The connector protective cover ensures that the battery connector is protected at different collision angles, avoiding physical damage. The battery protective assembly in this embodiment solves the problem of insufficient front-end protection of the battery pack in the prior art, realizing the integration of physical impact protection and connector protection. Therefore, when the battery pack faces impacts from bottom and front obstacles, it can significantly reduce the risk of damage to the battery and its connectors, providing more comprehensive safety protection for the battery pack and effectively improving the safety performance of the vehicle.

[0033] Combination Figures 1 to 4 As shown, according to a specific embodiment of this application, a battery protection assembly is provided.

[0034] The battery protection assembly includes a protective body 1 and a connector protective cover 2. The protective body 1 is provided with a first battery connection part 101 and a vehicle body connection part 102. The protective body 1 is connected to the battery through the first battery connection part 101 and to the vehicle body through the vehicle body connection part 102. The connector protective cover 2 is located on one side of the protective body 1 along its length and is connected to the protective body 1. The connector protective cover 2 is provided with a second battery connection part 201 and is connected to the battery through the second battery connection part 201. When the battery protection assembly is connected to the battery through the first battery connection part 101 and the second battery connection part 201, the protective body 1 covers the end face of the battery along the horizontal direction of the battery, part of the connector protective cover 2 covers the battery connector along the horizontal direction of the battery, and another part of the connector protective cover 2 is located on the side of the battery connector closer to the ground and covers the battery connector along the height direction of the battery.

[0035] Applying the technical solution of this embodiment, the protective body 1 is connected to the battery via the first battery connection part 101 and to the vehicle body via the vehicle body connection part 102, forming a stable structure. The connector protective cover 2 is connected to the battery via the second battery connection part 201. The connector protective cover 2 can partially shield the battery connector along the horizontal direction of the battery, while another part is located on the side of the battery connector closer to the ground and provides protection along the height direction of the battery. When the protective assembly is installed in place, the protective body 1 effectively shields the end face of the battery along the horizontal direction, preventing frontal collisions from directly impacting the battery. The connector protective cover 2 ensures that the battery connector is protected at different collision angles, avoiding physical damage. The battery protection assembly in this embodiment solves the problem of insufficient front-end protection of the battery pack in the prior art, realizing the integration of physical impact protection and connector protection. Therefore, when the battery pack faces impacts from bottom and front obstacles, it can significantly reduce the risk of damage to the battery and its connectors, providing more comprehensive safety protection for the battery pack and effectively improving the safety performance of the vehicle.

[0036] In this embodiment, Figure 1 , Figure 2 , Figure 3 The downward direction of the height is from the ground to the roof of the vehicle. Figure 1 , Figure 2 , Figure 3 The right side is where the battery is located. Figure 1 , Figure 2 , Figure 3 The left side is where the exhaust system is located. Figure 4 The downward direction of the height is from the roof of the vehicle to the ground. Figure 4 The right side of the image is where the exhaust system is located. Figure 4 The left side of the image shows the side where the battery is located.

[0037] Furthermore, a heat insulation layer 3 is provided on the side of the connector protective cover 2 that is away from the battery.

[0038] In this embodiment, a heat insulation layer 3 is added to the side of the connector protective cover 2 facing away from the battery. This design allows the battery protection assembly to provide collision protection while effectively blocking heat radiation from the front exhaust system, protecting the battery pack from the effects of high-temperature environments. By integrating collision protection, protection, and heat insulation functions into the battery protection assembly, the battery protection assembly in this embodiment not only simplifies the safety architecture at the front of the battery pack but also optimizes the overall vehicle layout, reduces production costs, and improves assembly efficiency.

[0039] Specifically, the protective body 1 includes a battery protection assembly 10. A connector protective cover 2 is provided on one side of the battery protection assembly 10 along its length, and the battery protection assembly 10 is connected to the connector protective cover 2. A first flange 11 is provided on the first side of the battery protection assembly 10 along its height, and a first battery connection part 101 is provided on the first flange 11. A second flange 12 is provided on the second side of the battery protection assembly 10 along its height, and a vehicle body connection part 102 is provided on the second flange 12. The first side of the battery protection assembly 10 along its height is located close to the ground. The battery protection assembly 10 is set at an angle to the height direction so that an anti-collision space is formed between the battery protection assembly 10 and the battery.

[0040] In this embodiment, a first flange 11 is provided on the first side in the height direction of the battery protection assembly 10, and a first battery connection part 101 is provided on the first flange 11 for connecting with the battery pack; while a second flange 12 is provided on the second side, and the second flange 12 is equipped with a vehicle body connection part 102 for fixing with the vehicle longitudinal beam; a collision protection space is formed between the battery protection assembly 10 and the battery. When the vehicle encounters an obstacle in front and below, this space can play a buffering role and reduce the impact of direct impact on the battery.

[0041] Furthermore, a third flange 13 is provided along the edge of the second flange 12, and the third flange 13 extends toward the first side in the height direction of the battery protection assembly 10.

[0042] In this embodiment, the third flange 13 added to the edge of the second flange 12 extends toward the first side of the battery protection assembly 10, that is, the third flange 13 is set toward the ground, which can provide additional support and protection when driving on uneven road surfaces.

[0043] Furthermore, the battery protection assembly 10 is provided with a plurality of first reinforcing ribs 14, which are spaced apart along the length of the battery protection assembly 10.

[0044] In this embodiment, multiple first reinforcing ribs 14 are spaced apart along the length of the battery protection assembly 10, which significantly enhances the structural stability of the battery protection assembly 10. When subjected to forward collision or bottom scraping, they can better disperse the impact force and reduce direct damage to the battery pack.

[0045] The shape, size, and distribution density of the first reinforcing rib 14 can be adjusted according to actual needs to adapt to the battery pack protection requirements of different hybrid vehicle models and ensure optimal protection effect.

[0046] Furthermore, the connector protective cover 2 includes a protective cover body 20, which is located on one side of the protective body 1 along its length and is connected to the protective body 1. A fourth flange 21 is provided on the edge of the protective cover body 20 along its height direction. The fourth flange 21 is folded towards the side where the battery is located and a second battery connection part 201 is provided on the fourth flange 21. A heat insulation layer 3 is provided on the side of the protective cover body 20 away from the battery. When the protective body 1 is connected to the battery, the protective cover body 20 blocks the battery along the horizontal direction of the battery, and the fourth flange 21 is located on the side of the battery connector closer to the ground and blocks the battery connector along the height direction of the battery.

[0047] In this embodiment, the connector protective cover 2 includes a protective cover body 20, located on one side of the protective body 1 along its length and connected thereto. Its height edge has a fourth flange 21, folded towards the battery side, and a second battery connection portion 201 is provided on the fourth flange 21. A heat insulation layer 3 is provided on the side of the protective cover body 20 away from the battery. When the protective body 1 is connected to the battery, the protective cover body 20 shields the battery along the horizontal direction of the battery, while the fourth flange 21 is located on the side of the battery connector closest to the ground and shields the battery connector along the height direction of the battery. Through the fourth flange 21 and the protective cover body 20, the connector area at the front of the battery is effectively covered and protected, enhancing the protection capability during a collision with the bottom of the vehicle. Simultaneously, the heat insulation layer 3 can isolate heat radiation from high-temperature components at the front of the vehicle, ensuring the battery pack can still operate safely in harsh environments. Furthermore, the flange and connection portion of the protective cover allow the protective plate to be firmly fixed to the battery pack, further improving the stability of the protection.

[0048] In other embodiments, the design of the fourth flange 21 can be more diverse, for example, by using different folding angles or adding additional cushioning material, to adapt to the needs of different vehicle models and working conditions.

[0049] Furthermore, a second reinforcing rib 22 is provided on the protective cover body 20.

[0050] In this embodiment, a second reinforcing rib 22 is added to the protective cover body 20, which can improve the stability and durability of the protective cover body 20 when subjected to impact, especially in the case of encountering obstacle collision. By setting reinforcing ribs in key stress-bearing parts, impact force can be effectively dispersed and absorbed even in complex driving environments, reducing direct damage.

[0051] In one exemplary embodiment of this application, the second reinforcing rib 22 is a ring structure, and the heat insulation layer 3 is coated on the second reinforcing rib 22 and the protective cover body 20.

[0052] Furthermore, the first battery connection portion 101 includes a first connection hole 1010, the body connection portion 102 includes a second connection hole 1020, the second battery connection portion 201 includes a third connection hole 2010, and a shock-absorbing sleeve is provided inside at least one of the first connection hole 1010, the second connection hole 1020, and the third connection hole 2010.

[0053] In this embodiment, the first connecting hole 1010, the second connecting hole 1020, and the third connecting hole 2010 are used to fix the battery protection assembly to the vehicle and the battery pack. The shock-absorbing sleeves inside the holes can enhance the vibration resistance of the connection parts, so that when the battery protection assembly is subjected to vibrations generated during vehicle operation, the shock-absorbing sleeves can absorb and buffer the vibration energy, effectively prevent the bolt connection from loosening, and ensure that the battery protection assembly is stably fixed in the predetermined position for a long time. This ensures the safety protection effect of the front end of the battery pack and the connector under complex working conditions, improves the reliability of the connection structure, and extends the service life of the battery protection assembly and the vehicle as a whole.

[0054] This application also provides a preferred embodiment of a battery protection assembly integrated with the front of a hybrid vehicle battery, belonging to the field of new energy vehicle battery protection technology, which can simultaneously provide anti-collision, heat insulation and connector protection for the front of the battery pack.

[0055] Specifically, in this embodiment, the battery protection assembly is installed on the front end of the hybrid vehicle battery pack, located between the battery pack and the exhaust system at the front of the vehicle. It is mainly designed to protect the front end of the battery in hybrid vehicles, and can protect the front end of the battery from damage caused by special working conditions such as manhole covers and bricks. The battery protection assembly integrates a protective cover for the battery front end connector, and at the same time, the battery protection assembly has a heat insulation effect.

[0056] The battery protection assembly includes a metal backplate (i.e., the aforementioned protective body 1), a heat insulation layer 3, and a connector protective cover 2. The metal backplate serves as the primary load-bearing structure, resisting external impacts. The connector protective cover 2 is formed by bending forward and upward from the upper edge of the metal backplate, constituting a protective structure that covers the electrical connectors at the front of the battery pack, preventing direct impact or scratches to the connectors (see reference). Figures 1 to 3 (As shown); the heat insulation layer 3 is fixedly covered in front of the connector protective cover 2 to reflect and isolate the heat transmitted from the exhaust system.

[0057] The metal back plate is provided with a first reinforcing rib 14 to improve the anti-collision rigidity of the metal back plate, and the connector protective cover 2 is provided with a second reinforcing rib 22 to enhance the protective capability.

[0058] Preferably, the metal backplate is made of high-strength steel plate with a thickness of 2-4mm, and has reinforcing ribs on the side facing the battery pack to improve its impact resistance.

[0059] Preferably, the battery protection assembly is fixedly connected to the battery pack housing frame and the vehicle body longitudinal beam by bolts, and a shock-absorbing sleeve is provided between the bolts and the battery mounting holes to buffer and absorb vibrations from the chassis.

[0060] Preferably, the lower edge of the battery protection assembly is provided with a forward-extending anti-scratch flange (i.e., the aforementioned third flange 13), which can make priority contact with the ground and smoothly transition when the vehicle passes through a slope or pothole, avoiding direct scratching of the lower front edge of the battery pack.

[0061] The beneficial effects of the battery protection assembly in this embodiment are:

[0062] 1) Integrated protection: Innovatively integrates three major functions—anti-collision, heat insulation, and connector protection—into a single component at the front of the battery pack, resulting in a compact structure that addresses multiple safety threats.

[0063] 2) Highly targeted: Specifically designed to address the unique risks at the front of the battery pack in hybrid vehicles (high exhaust temperature, front connectors, forward collisions), providing high protection efficiency.

[0064] 3) Significantly improved safety performance: The robust metal backplate and unique connector protective cover 2 structure can effectively resist the impact of special obstacles such as manhole covers and bricks, providing a solid barrier for the battery pack and critical circuits; the efficient heat insulation layer 3 ensures that the battery pack can still work safely in high-temperature environments.

[0065] 4) Reliable structure and easy installation: The overall structure is simple and reliable, and it is connected to the vehicle body and battery pack frame with bolts, which facilitates installation and subsequent maintenance.

[0066] The battery protection assembly in this embodiment addresses the issues of physical impact, high-temperature heat radiation, and connector damage to the front of the battery pack by incorporating a metal backplate as the main load-bearing component, a heat insulation layer covering its front, and a connector protective cover 2 extending forward from the backplate and bending upward. As an independent component located at the front of the battery pack, the battery protection assembly integrates the functions of a crash beam, heat insulation plate, and connector cover, effectively resisting impacts from obstacles (such as manhole covers or bricks) below the front of the vehicle. It also isolates the high temperature from the exhaust pipe and provides specialized protection for the electrical connectors at the front of the battery, thereby significantly reducing the risk of damage to the battery pack and its connectors in the event of a bottom collision.

[0067] According to another specific embodiment of this application, a battery system is also provided, the battery system having a battery protection assembly, the battery protection assembly being the aforementioned battery protection assembly.

[0068] In this embodiment, the battery system integrates the aforementioned battery protection assembly. The synergistic effect of the protective body 1 and the vehicle body connection 102 ensures a stable connection between the battery protection assembly and the vehicle body, while the first battery connection 101 ensures a tight fit between the protective body 1 and the battery, together forming a stable and reliable protective architecture. The connector protective cover 2 not only shields the battery connectors along the horizontal direction of the battery to prevent damage from side collisions, but also provides additional protection along the height direction of the battery on its side closest to the ground, effectively resisting impacts from below. This layout not only strengthens the structural integrity of the front end of the battery pack and reduces the possibility of damage to the battery and its connectors under complex road conditions, but also improves the safety and reliability of the entire battery system, providing a solid safety guarantee for vehicle operation.

[0069] According to another specific embodiment of this application, a vehicle is also provided, the vehicle having a battery system, the battery system being the battery system described above.

[0070] In this embodiment, the vehicle integrates the aforementioned battery protection assembly. Through the synergistic effect of the protective body 1 and the connector protective cover 2, the front-end safety protection capability of the vehicle's battery system is significantly enhanced. The protective body 1 shields the end face of the battery along the horizontal direction, effectively resisting forward physical impacts. The connector protective cover 2 not only shields the battery connectors along the horizontal direction but also provides protection along the height direction of the battery on the side closest to the ground. This integrated design ensures that even under complex road conditions, such as impacts from manhole covers or paving stones, the battery system and its critical connectors are fully protected, avoiding the risk of battery damage and system failure due to collisions, and improving the overall safety and reliability of the vehicle.
