Power batteries are used not only in energy storage and power systems such as hydroelectric, thermal, wind, and solar power plants, but also in electric transportation tools such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. As the application fields of power batteries continue to expand, the market demand for them is also continuously increasing. 【0031】 The inventors realized that as batteries are applied in an increasing number of situations, the probability of collisions or impacts to batteries increases, making battery protection increasingly important and preventing damage when collisions or impacts occur in applications. 【0032】 To address the problem of batteries being damaged during collisions or impacts, the applicant has discovered through research that by installing a lightweight energy-absorbing member on one side of the bottom plate within the battery housing that faces the housing space, the impact force during a collision or impact can be absorbed, reducing the impact force that reaches the battery module and providing cushioning and protection to the battery module. 【0033】 Based on the above considerations, in order to solve the problem that battery modules are prone to damage from impact or collision, the inventors conducted diligent research and designed a battery housing. By installing a lightweight energy-absorbing member on one side of the bottom plate inside the battery housing that faces the housing space, the impact force during collision or impact is mitigated and absorbed, thereby providing protection to the battery module. 【0034】 The battery housing and battery disclosed in the embodiments of this application can be used in power consumption devices such as vehicles, ships, or aircraft, but are not limited thereto. A power supply system comprising the battery housing, battery, etc. disclosed in this application can be used to constitute such a power consumption device, and in this way, when a collision or impact occurs, the lightweight energy-absorbing member in the battery housing can provide protection to the battery module, preventing damage to the battery module when a collision or impact occurs, and helping to improve the battery's lifespan. 【0035】 Embodiments of this application provide a power consumption device that uses a battery as a power source, and the power consumption device may be, but is not limited to, a mobile phone, tablet, laptop computer, electric toy, power tool, battery car, electric vehicle, steamship, spacecraft, etc. Here, electric toys may include stationary or mobile electric toys, for example, game consoles, electric vehicle toys, electric steamship toys and electric airplane toys, and spacecraft may include airplanes, rockets, space aircraft and spacecraft, etc. 【0036】 For the sake of explanation, the following embodiments will be described using a battery housing 1 of one embodiment of this application as an example. 【0037】 Referring to Figure 1, Figure 1 is an exploded view of the battery housing 1 in an inverted state according to several embodiments of the present application. The battery housing 1 includes a frame 12, a bottom plate 11, and a lightweight energy absorbing member 13. The frame 12 has an open structure at both ends, and the frame 12 and the bottom form a housing space enclosed by it with one end open. The battery module is installed in the housing space, and the lightweight energy absorbing member 13 is also installed in the housing space and is located on one side of the bottom facing the housing space, that is, the lightweight energy absorbing member 13 is installed between the bottom plate 11 and the battery module. When a collision or impact occurs, the lightweight energy absorbing member 13 installed between the bottom plate 11 and the battery module can absorb the impact force for the battery module, thereby providing cushioning and protection to the battery module. 【0038】 The battery housing 1 may further have a protective plate 14, which is also installed on one side facing the housing space of the bottom plate 11, that is, the protective plate 14 is also installed between the battery module and the bottom plate 11, so that when a collision or impact occurs, the protective plate 14 installed between the bottom plate 11 and the battery module can absorb the impact force for the battery module, thereby providing cushioning and protection to the battery module. 【0039】 The battery comprises a battery housing 1 and a battery module, the battery module being housed within the battery housing 1. Here, the battery housing 1 is used to provide a housing space for the battery module, and the battery module can employ various structures. In some embodiments, the battery housing 1 may include a frame 12 and a bottom plate 11, the frame 12 and bottom plate 11 forming a housing space with one end open, the battery module being installed within the housing space, and a lightweight energy absorbing member 13 is further installed within the battery housing 1, positioned between the bottom plate 11 and the battery module, so that when a collision or impact occurs, the lightweight energy absorbing member 13 installed between the bottom plate 11 and the battery module can absorb the impact force for the battery module, thereby providing cushioning and protection to the battery module, and because the lightweight energy absorbing member 13 is light in weight, it can provide protection to the battery module without increasing the weight excessively. 【0040】 It should be explained that in this application, the battery module may be a battery module consisting of battery cells, in which case the battery module may include end plates and side plates. In this application, the battery module may also be a set consisting of multiple battery cells without end plates or side plates. 【0041】 In some embodiments of this application, the battery can be used not only as an operating power source for power-consuming devices, but also as a driving power source for power-consuming devices, providing driving power to power-consuming devices in place of or in place of gasoline or natural gas. 【0042】 In a battery, a battery module includes multiple battery cells, and there may be multiple battery cells. The connections between the multiple battery cells may be in series, in parallel, or in series-parallel. Series-parallel connection means that the multiple battery cells may be connected in series or in parallel.

The battery cell may have a flattened shape, a rectangular parallelepiped, or other shape. 【0044】 The power-consuming devices according to some embodiments of this application include a battery. The power-consuming device may be a vehicle, which may be a fuel-powered vehicle, a gas vehicle, or a new energy vehicle, which may be a pure electric vehicle, a hybrid vehicle, or a range-extender vehicle. The battery is installed inside the vehicle, and may be installed at the bottom, front, or rear of the vehicle. The battery may be used to supply power to the vehicle, for example, as the operating power source for the vehicle. The vehicle may further include a controller and a motor, the controller being used to control the battery to supply power to the motor, for example, to meet the operating power consumption requirements for starting the vehicle, navigation, and driving. 【0045】 According to some embodiments of this application, as shown in Figure 1, the battery housing 1 includes a bottom plate 11 and a frame 12, both ends of the frame 12 having openings, and the opening at one end of the frame 12 being connected to the edge of the bottom plate 11 to form a housing space, and a lightweight energy absorbing member 13 is installed on one side of the bottom plate 11 facing the housing space within the housing space. 【0046】 The frame 12 is the side wall of the battery housing 1, and the frame 12 surrounds and forms a housing space having openings at both the top and bottom, and the bottom plate 11 is connected to the opening at one end of the frame 12, thereby forming a housing space with one end open, the battery module is housed in the housing space, the lightweight energy absorbing member 13 is installed stacked on the bottom plate 11 of the battery housing 1 and is located above the battery module. 【0047】 In this embodiment, the lightweight energy absorbing member 13 is installed in the housing space formed by the bottom plate 11 and the frame 12 inside the battery housing 1, and the lightweight energy absorbing member 13 is installed on one side of the bottom plate 11 facing the housing space, that is, the lightweight energy absorbing member 13 is installed between the bottom plate 11 and the battery module. As a result, when an impact or collision occurs at the bottom of the battery housing 1, the lightweight energy absorbing member 13 can absorb the impact energy caused by the impact or collision, significantly reducing the vibration, pressure, and impact intensity experienced by the battery module inside the battery housing 1, providing cushioning and protection to the battery module. Furthermore, since the weight of the lightweight energy absorbing member 13 is relatively small, it is possible to provide protection to the battery module without increasing the weight excessively. 【0048】 As shown in Figures 2 and 3, some embodiments of this application further include a protective plate 14, which is installed in the housing space and is located on one side of the bottom plate 11 facing the housing space. 【0049】 The battery housing 1 includes a frame 12, a bottom plate 11, and a protective plate 14. The frame 12 and the bottom plate 11 form a housing space enclosed by the frame with one end open. The protective plate 14, the battery module, and the lightweight energy absorbing member 13 are installed within the housing space. The protective plate 14 is located between the battery module and the bottom plate 11, and the lightweight energy absorbing member 13 may be installed between the protective plate 14 and the bottom plate 11, or between the protective plate 14 and the battery module. The protective plate 14 may be single-layered or multi-layered. The multi-layered protective plates 14 may be spaced apart or stacked. The protective plate 14 may be made of polypropylene or resin material. 【0050】 In this embodiment, the installation of the protective plate 14 further provides protection to the battery module inside the battery housing 1, absorbs the impact force generated during collision or impact processes, and reduces the vibration, pressure, and impact intensity experienced by the battery module inside the battery housing 1, thereby preventing damage to the battery module when it is impacted or collides with the battery housing 1, and improving the battery's lifespan. 【0051】 As shown in Figure 3, according to some embodiments of this application, the protective plate 14 has a hollow structure. 【0052】 The hollow protective plate 14 has multiple holes spaced apart, with the size and shape of the holes and the number of holes provided as needed. Selectively, multiple circular or polygonal holes are uniformly provided between the protective plates 14. 【0053】 In this embodiment, less material is used for the hollow protective plate 14, reducing costs and weight, thereby providing protection to the battery module while reducing overall weight. 【0054】 As shown in Figures 2 and 3, according to some embodiments of this application, the protective plate 14 and the bottom plate 11 are spaced apart and form a cavity. 【0055】 The battery housing 1 includes a frame 12, a bottom plate 11, a protective plate 14, and a lightweight energy absorbing member 13. The bottom plate 11 is fixed to the bottom end opening of the frame 12, and then the protective plate 14 is installed in the housing space formed by the bottom plate 11 and the frame 12, and is installed at a distance from the bottom plate 11 to form a cavity. The protective plate 14 is located between the bottom plate 11 and the battery module, and the periphery of the protective plate 14 is fixed to the inner wall of the frame 12, thereby fixing the protective plate 14 within the housing space. The lightweight energy absorbing member 13 may be installed between the protective plate 14 and the bottom plate 11 or between the protective plate 14 and the battery module. 【0056】 In this embodiment, the formation of a cavity between the bottom plate 11 and the protective plate 14 can further reduce the impact force generated during impact or collision, and reduce the magnitude of the impact force when it reaches the battery module, thereby further protecting the battery module. Furthermore, a medium may be placed in the cavity, which further reduces the impact force generated during impact or collision and provides protection to the battery module. 【0057】 As shown in Figures 2 and 3, according to some embodiments of this application, the lightweight energy absorbing member 13 is installed inside the cavity. 【0058】 The battery housing 1 includes a frame 12, a bottom plate 11, a protective plate 14, and a lightweight energy absorbing member 13. The bottom plate 11 is fixed to the bottom end opening of the frame 12, and then the protective plate 14 is placed in the housing space formed by the bottom plate 11 and the frame 12. The periphery of the protective plate 14 is fixed to the inner wall of the frame 12 and is installed at a distance from the bottom plate 11 to form a cavity. The protective plate 14 is located between the bottom plate 11 and the battery module, and the lightweight energy absorbing member 13 is installed between the protective plate 14 and the bottom plate 11. 【0059】 In this embodiment, the lightweight energy absorbing member 13 is installed in a cavity formed between the protective plate 14 and the bottom plate 11. That is, the multi-layer energy absorbing installation of the protective plate 14 and the lightweight energy absorbing member 13 can further improve the impact prevention effect. In this way, when the bottom of the battery housing 1 is subjected to an external impact, the energy is first absorbed by the lightweight energy absorbing layer, which has large elastic deformation, and then the excess energy is absorbed by the protective plate 14, further improving protection for the battery pack. Furthermore, the lightweight energy absorbing member 13 and the protective plate 14 that protect the battery module can be installed more effectively, reducing the space occupied and maximizing the protective effect of the protective plate 14 and the lightweight energy absorbing member 13 on the battery module. 【0060】 Referring to Figures 1 to 3, according to some embodiments of this application, an injection hole 121 communicating with a housing space is provided in the side wall of the frame 12, and the injection hole 121 is used to inject a material that forms a lightweight energy absorbing member 13 into the housing space. 【0061】 The injection hole 121 is a through hole provided in one of the side walls of the frame 12, and there may be one injection hole 121 or multiple injection holes. 【0062】 In this embodiment, the provision of injection holes 121 in the frame 12 allows for the injection of material to form the lightweight energy absorbing member 13 into the battery housing 1 after the assembly of the battery housing 1 is complete, thereby providing the battery module with protection by equipping the battery housing 1 with the lightweight energy absorbing member 13. If there are multiple injection holes 121, rapid injection of the lightweight energy absorbing member 13 can be achieved. 【0063】 Referring to Figures 1 to 3, according to some embodiments of this application, the injection hole 121 is provided in the side wall of the frame 12 corresponding to the cavity. 【0064】 The battery housing 1 includes a frame 12, a bottom plate 11, and a protective plate 14. The frame 12 and the bottom plate 11 enclose and form a housing space, the protective plate 14 is installed within the housing space, and a cavity is formed between the protective plate 14 and the bottom plate 11. When a lightweight energy absorbing member 13 is installed in the cavity, the protective plate 14 and the lightweight energy absorbing member 13 can provide maximum protection to the battery module. When the lightweight energy absorbing member 13 is installed, the injection hole 121 may be installed in the area where the side wall of the frame 12 and the cavity face each other, thereby installing the lightweight energy absorbing member 13 in the cavity and achieving maximum protection to the battery module. 【0065】 In this embodiment, the injection holes 121 are positioned to correspond to the cavities of the frame 12, thereby injecting the material forming the lightweight energy absorbing member 13 into the cavities. Similarly, one or more injection holes 121 may be provided, and by providing multiple injection holes 121, rapid injection of the material for the lightweight energy absorbing member 13 can be achieved. 【0066】 According to some embodiments of this application, the lightweight energy absorbing member 13 includes a foamed adhesive material. 【0067】 The lightweight energy-absorbing member 13 may be a foamed adhesive material, or other material such as rubber, resin, or foam, and can be used in production and application. 【0068】 In this embodiment, the lightweight energy absorbing member 13 includes a foamed adhesive material, which has a high buffering energy absorption effect, thereby providing better protection to the battery module, and the foamed adhesive material has a relatively low cost, thereby reducing the cost of the lightweight energy absorbing member 13. 【0069】 According to some embodiments of this application, the application further provides a battery including a battery housing 1 as described in any one of the above-described solutions. 【0070】 According to some embodiments of this application, the application further provides a power consumption device comprising a battery of any one of the above-described solutions, wherein the battery is used to provide electrical energy to the power consumption device. 【0071】 The power consumption device may be any one of the aforementioned devices or systems that utilize batteries. 【0072】 This application provides a battery housing 1, which includes a frame 12, a bottom plate 11, and a protective plate 14. The frame 12 and the bottom plate 11 enclose and form a housing space, and both the battery module and the protective plate 14 are installed within the housing space. The protective plate 14 is located between the battery module and the bottom plate 11, and the protective plate 14 and the bottom plate 11 are spaced apart to form a cavity. A lightweight energy absorbing member 13 is installed in the cavity, so that when an impact or collision occurs to the bottom of the battery housing 1, the lightweight energy absorbing member 13 and the protective plate 14 can absorb the impact energy from the impact or collision, significantly reducing the vibration, pressure, and impact intensity experienced by the battery module inside the battery housing 1, and providing cushioning and protection to the battery module. Furthermore, the protective plate 14 has a hollow structure, so the weight of the lightweight energy absorbing member 13 and the hollow protective plate 14 is relatively small, and the battery housing 1 according to this application can provide protection to the battery module without increasing the weight excessively. 【0073】 Finally, it should be noted that the above embodiments are merely illustrative of the technical concepts of this application and do not limit them.
