[0047] As in the background art, the ordinary battery box cover in the related art has the problem of causing a relatively large self - weight of the battery, which affects the vehicle weight and the battery space utilization rate. Through research by the inventor, it is found that the reason for this problem is that the current ordinary battery box cover is set inside the vehicle and has no direct relation with the vehicle body.

[0048] In view of the above - mentioned technical problems, the embodiments of the present application provide an integrated battery and a vehicle. The integrated battery includes a box body, a battery cell module, and a support assembly. A beam body is arranged on the bottom plate in the box body space, and the battery cell module can be fixed through the beam body, thereby providing a stable power source. A support assembly is arranged between the beam body and the box cover, and the sum of the heights of the support assembly and the beam body is greater than the height of the battery cell module, so as to protect the battery cell module while improving the load - bearing capacity of the battery box cover. The vehicle includes the above - mentioned integrated battery. In this way, the box cover of the integrated battery can be used as the bottom plate of the vehicle, bearing the self - weight of the vehicle body and the external trampling conditions, realizing the integration of the battery and the vehicle body, reducing the vehicle weight, and improving the battery space utilization rate.

[0049] In order to make the above - mentioned objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0050] In a first aspect, an embodiment of the present application provides an integrated battery. Please refer to Figure 1 , which includes a box body 100, a battery cell module 200, and a support assembly 300. This integrated battery can be used in vehicles or other electrical devices, and this embodiment does not limit this here.

[0051] In this embodiment, the box body 100 may include: a box cover 110, a bottom plate 120, and a beam body 130 disposed on the bottom plate 120 and within the space of the box body 100.

[0052] The box body 100, as the outer shell for accommodating and protecting the battery system, has a certain stability. The box cover 110 and the bottom plate 120 can be made of high-strength aluminum alloy materials, having good impact resistance and corrosion resistance. The box cover 110 can be tightly connected to the bottom plate 120 by bolts to ensure the sealing and structural strength of the box body 100. The bottom plate 120 is provided with a plurality of fixing holes for installing the beam body 130 and the battery cell module 200. In addition, the surface of the bottom plate 120 is anti-slip treated to increase the stability of the battery cell module 200. The beam body 130 is composed of at least one longitudinal beam 132 and / or at least one cross beam 131, forming a grid-like structure. The beam body 130 is made of a lightweight and high-strength material, such as carbon fiber composite material, which not only ensures the structural strength but also reduces the overall weight. Further, the beam body 130 is provided with a plurality of installation grooves for fixing the battery cell module 200.

[0053] The battery cell module 200 is fixed between the beam bodies 130. The battery cell module 200 is composed of a plurality of battery cell units, and each battery cell unit uses a lithium-ion battery with a high energy density. The beam bodies 130 and the bottom plate 120 jointly form an accommodating space to support the battery cell module 200, so that the battery cell module 200 is in close contact with the beam bodies 130 through thermal conductive silicone to ensure good heat dissipation performance.

[0054] The support assembly 300 is disposed between the beam bodies 130 and the box cover 110, and the sum of the heights of the support assembly 300 and the beam bodies 130 is greater than the height of the battery cell module 200. The support assembly 300 is used to fix and support the battery cell module 200 to ensure its stability within the box body 100 and to slow down the impact on the box cover 110 from the outside. The support assembly 300 may include a plurality of elastic support members and shock pads. The elastic support members are made of high-strength spring steel materials, having good elasticity and durability. The shock pads are made of high-density rubber materials and can effectively absorb vibration and impact. Exemplarily, when an external impact or vibration occurs, the force received by the box cover 110 can be absorbed and alleviated by the support assembly 300 and further transmitted to the beam bodies 130 for sharing, thereby reducing the deformation amount of the box cover 110 and at the same time ensuring the stability of the battery cell module 200 within the box body 100 and preventing damage to the battery cell module 200.

[0055] It should be noted that there is no limitation on the setting method between the support component 300 and the beam body 130 and the box cover 110. In some embodiments, the support component 300 can be fixedly connected to the beam body 130 and the box cover 110 by hot riveting, magnetic attraction or back glue, so as to improve the stability. Or the support component 300 can be not fixed, so that its position can be adjusted according to specific requirements to ensure a better shock absorption position of the box cover 110.

[0056] Please continue to refer to Figure 1 , in a possible implementation manner, the beam body 130 includes at least one cross beam 131 and / or at least one longitudinal beam 132 connected to at least one cross beam 131. The cross beam 131 can be arranged parallel to the frame of the box body 100, and the cross beam 131 is perpendicular to the longitudinal beam 132, forming a grid-like structure, which helps the heat dissipation of the battery cell module 200 and ensures that the battery cells 220 maintain an appropriate temperature during operation. In this embodiment, the overall width of the battery system is relatively large, and the longitudinal beam 132 can be set to ensure the mode of the battery pack.

[0057] The battery cells 220 of the battery cell module 200 are fixed in the gaps between the cross beams 131. The positions of the cross beams 131 and the longitudinal beams 132 take into account the size and spacing of the battery cells 220. When the number of cross beams 131 is two, the two cross beams 131 are arranged in parallel and are both perpendicular to the longitudinal beam 132, that is, similar to the structure of the Chinese character "gan". The box cover 110 is connected to the frame of the box body 100 on the side where there is no cross beam 131. There is a gap between the two cross beams 131. The cross beams 131 and the bottom plate 120 together form a groove structure that can accommodate the battery cell module 200 to restrain the battery cells 220 and prevent them from moving or loosening in the box body 100, enhancing the overall stability of the battery cell module 200.

[0058] It should be noted that there is no support component 300 between the cross beam 131 in the middle of the box body 100 and the box cover 110. Since the battery cell module 200 also has an upper cover, the upper cover will cover the cross beam 131 in the middle of the box body 100, so the support component 300 cannot be set. And the number of the upper covers is two, which are respectively arranged on both sides of the longitudinal beam 132 and do not contact the cross beams 131 at the edge of the box body 100. Therefore, the support component 300 can be set on the longitudinal beam 132 and the cross beams 131 at the edge of the box body 100.

[0059] There is a gap between the battery cells 220 of the battery cell module 200 and the longitudinal beam 132. Since the cross beam 131 and the longitudinal beam 132 are fixed by welding, there are welding beads. There is a gap between the battery cells 220 and the longitudinal beam 132. In this way, the welding beads can be avoided to prevent affecting the setting of the battery cells 220. At the same time, it can also provide necessary buffering and shock absorption space to enhance the impact resistance of the battery cell module 200.

[0060] The integrated battery provided in the embodiment of the present application is configured with a support assembly 300 between the beam body 130 and the box cover 110, and the sum of the heights of the support assembly 300 and the beam body 130 is greater than the height of the battery cell module 200, so that the force exerted on the box cover 110 can be absorbed and alleviated by the support assembly 300, and further transmitted to the beam body 130 for sharing, thereby reducing the deformation of the box cover 110 and not squeezing the battery cell module 200, so that the box cover 110 can withstand greater forces and can serve as a floor inside the vehicle body, bearing the weight of the vehicle body and external trampling conditions, thereby realizing battery-body integration.

[0061] Please refer to Figure 2 In a possible implementation, the support assembly 300 may include: a support base 310 and a fixing element 320. The support base 310 is made of high-strength material, such as aluminum alloy or carbon fiber composite material, to ensure that it has sufficient strength and durability.

[0062] The support base 310 is disposed between the beam 130 and the box cover 110, and the sum of the heights of the support base 310 and the beam 130 is greater than the height of the battery module 200. Since the battery module 200 is composed of a plurality of battery units, the battery unit includes a pole 210, a battery 220, and an explosion-proof valve, and the pole 210 is located inside the battery 220 and is higher than the surface of the battery 220, the height of the battery module 200 is the height of the pole 210, and the battery cell will fail when the pole 210 is squeezed, so the sum of the heights of the support base 310 and the beam 130 is greater than the height of the pole 210, which can provide sufficient support and shock absorption space, so that the external impact will not affect the pole 210. The support base 310 can be tightly connected to the beam 130 by bolts, adhesives or other fixing methods to provide a solid support structure to prevent the battery module 200 from moving in the box 100.

[0063] The fixing element 320 is used to fix the support base 310 and the box cover 110. The fixing element 320 can be a structure such as a rivet, a buckle or a clamp to ensure the stability and reliability of the entire support assembly 300.

[0064] As an example, a plurality of mounting grooves are provided on the top of the support base 310 for cooperating with the fixing element 320 to ensure a tight connection with the box cover 110. The fixing element 320 is a rivet. The fixing element 320 is inserted into the mounting groove of the support base 310, and the support base 310 and the box cover 110 are fixed together by riveting to ensure the stability of the entire support assembly 300.

[0065] Please continue to refer to Figure 2, in a possible implementation, the fixing element 320 may include: a nut 321 and a bolt 322. The nut 321 and the bolt 322 may be made of high-strength fastener materials, such as stainless steel or high-strength alloy steel, to ensure good fastening performance and durability.

[0066] The nut 321 is passed through the support base 310 and the box cover 110. A groove is provided on the support base 310. The nut 321 passes through the box cover 110 and fixedly connects the box cover 110 and the support base 310 to ensure the reliability of the entire support assembly 300. At the same time, the nut 321 and the bolt 322 are convenient for installation and disassembly, making the fixing element 320 easy to maintain and replace.

[0067] In the specific implementation of this embodiment, the support assembly 300 further includes: a first sealing element 330;

[0068] The first sealing element 330 is arranged on the bolt 322.

[0069] The first sealing element 330 may be made of a highly elastic shock-absorbing material, such as rubber or silicone material. It is arranged on the bolt 322 and further contacts the box cover 110 and the support base 310, providing good compressibility and resilience. On the one hand, the first sealing element 330 can provide effective sealing performance to prevent the bolt 322 from loosening. On the other hand, it also has good shock-absorbing and anti-impact functions. When the box cover 110 is violently impacted, it can buffer part of the impact force and protect the internal components of the battery system.

[0070] The integrated battery provided by the embodiment of the present application fixes the support base 310 and the box cover 110 through the fixing element 320, which can further enhance the stability of the support assembly 300, prevent the support assembly 300 from shifting, and protect the battery cell module 200.

[0071] Please refer to Figure 3 , on the basis of the above embodiment, the integrated battery further includes: a pressing strip assembly 400. The pressing strip assembly 400 is made of a high-strength and elastic material, such as aluminum alloy, carbon fiber composite material or high-density plastic, and can absorb and relieve external vibration and impact, protecting the battery cell 220 from mechanical stress damage.

[0072] The lashing component 400 is disposed between the shoulder of the battery cell 220 in the battery cell module 200 and the box cover 110, and is located between the pole columns 210 of different battery cells 220 in the battery cell module 200. Each battery cell 220 in the battery cell module 200 has a pole column 210, including a positive pole column and a negative pole column. The shoulder of the battery cell 220 is the upper structure of the battery cell 220, that is, between the positive pole column and the negative pole column. The length and shape of the lashing component 400 are designed to cover the shoulder of the battery cell 220 and provide support between the pole columns 210 of different battery cells 220 in the battery cell module 200, such as a cylinder or a cuboid. At the same time, physical isolation is provided between the pole columns 210 of different battery cells 220 in the battery cell module 200 to prevent short circuits and electrical interference between the pole columns and improve the safety of the battery system. The number of lashing components 400 can be multiple, and this application does not limit the number of lashing components 400 here.

[0073] The battery cells 220 in the battery cell module 200 are arranged horizontally and closely. Exemplarily, the lashing component 400 can be arranged between the pole columns 210 of different battery cells 220 along the arrangement direction of the battery cells 220, that is, between the positive pole column and the negative pole column of the same battery cell 220, and extend to other battery cells 220. It can also be arranged between every two battery cells 220, that is, between the pole columns 210 of different battery cells 220, or both arrangement methods exist. When there are multiple lashing components 400, the lashing components 400 are arranged in parallel or perpendicular to each other to form a grid-like structure to ensure comprehensive protection of the battery cell module 200.

[0074] The integrated battery provided by the embodiment of this application can protect the pole column 210, absorb and relieve external vibration, transfer the force to the position where it can bear the force, and prevent the pole column 210 from being damaged by setting the lashing component 400 between the shoulder of the battery cell 220 in the battery cell module 200 and the box cover 110.

[0075] Please refer to Figure 3 and Figure 4, in a possible implementation, the strapping component 400 is provided with a transverse protrusion 410 and a longitudinal protrusion 420. The transverse protrusion 410 and the longitudinal protrusion 420 are perpendicularly arranged, and the height of the transverse protrusion 410 and the height of the longitudinal protrusion 420 are greater than the height of the pole 210. In this way, the strapping component 400 can evenly distribute the pressure on the shoulders of the battery cell 220, support between two adjacent and attached battery cells 220 through the transverse protrusion 410, and the longitudinal protrusion 420 is arranged on the shoulders of different battery cells 220, so as to comprehensively protect the pole 210. Moreover, the height of the transverse protrusion 410 and the height of the longitudinal protrusion 420 are greater than the height of the pole 210, which can prevent the pole 210 from being squeezed, thereby improving the overall stability of the battery cell module 200. In addition, the strapping component 400 is T-shaped, which can provide a large contact area, form a firm connection with the battery cell 220 and the box cover 110, and enhance the structural support of the entire battery system.

[0076] In addition, structural adhesive can also be provided on the transverse protrusion 410 and the longitudinal protrusion 420, so as to be adhesively fixed with the battery cell 220 to prevent the strapping component 400 from slipping off. In some embodiments, the strapping component 400 can also include a strapping bar and a fixing member. The fixing member is made of high-strength stainless steel material, and the strapping bar is fixed between the shoulder of the battery cell 220 and the box cover 110 through bolts, ensuring the stability of the strapping bar and further enhancing the impact resistance of the battery cell module 200.

[0077] The integrated battery provided by the embodiments of the present application, by providing the transverse protrusion 410 and the longitudinal protrusion 420 on the strapping component 400, can protect the pole 210 from being squeezed when the box cover 110 is stepped on, improve the overall stability of the battery cell module 200, and at the same time increase the strength of the strapping component 400.

[0078] Please refer to Figure 5 , in a possible implementation, the integrated battery further includes: a second sealing element 500;

[0079] The second sealing element 500 is arranged between the side plate of the box body 100 and the box cover 110. In this way, it can provide sealing for the box body 100, prevent moisture, dust and pollutants from entering the interior of the box body 100, and protect the battery cell module 200 and other internal components. The second sealing element 500 can be made of a high-elasticity material to adapt to the slight deformation between the box body 100 and the box cover 110 and maintain a long-term stable sealing effect. In addition, the second sealing element 500 can also absorb and relieve external vibration and impact, providing additional shock absorption protection.

[0080] As an example, the second sealing element 500 is arranged along the contact surface between the side plate of the box body 100 and the box cover 110, and is fixedly connected to the contact surface through fixing methods such as bolts and snap connections to ensure the continuity and integrity of the seal.

[0081] Please refer to Figure 1 and Figure 5 In a possible implementation, the integrated battery further includes: a third sealing element 600;

[0082] The third sealing element 600 is disposed at the edge of the cover 110, and the corresponding setting height of the third sealing element 600 is greater than the height of the cover 110. When the integrated battery is used in a vehicle, the lower part of the battery system is a metal plane in the vehicle. To prevent the rigid connection between the vehicle body and the battery system from damaging the battery system, the third sealing element 600 is provided. On the one hand, its size and shape match the edge of the cover 110 and it is arranged around the entire edge of the cover 110 to ensure the sealing of the battery system. On the other hand, the third sealing element 600 can be made of a material with high elasticity and durability. The corresponding setting height of the third sealing element 600 is greater than the height of the cover 110, which can effectively absorb and relieve the vibration, impact and noise during the vehicle movement, reduce the vehicle NVH (Noise, Vibration, Harshness) performance, and reduce the influence of these vibrations on the cover 110 and the internal battery system.

[0083] Exemplarily, during the vehicle driving process, especially on bumpy roads or in the event of a collision, the third sealing element 600 can buffer the external impact force, reduce the influence of mechanical stress on the battery system, protect the battery module and other internal components, extend the service life of the battery system, and ensure the safe operation of the battery system under various driving conditions.

[0084] The integrated battery provided by the embodiment of the present application can provide sealing for the box body 100 and provide a shock absorption and protection effect by arranging the second sealing element 500 between the side plate of the box body 100 and the cover 110, and arranging the third sealing element 600 at the edge of the cover 110, so as to prevent the battery system from being damaged by external forces.

[0085] In a second aspect, the embodiment of the present application provides a vehicle 800, please refer to Figure 6 , including the integrated battery 700 in the first aspect and any possible implementation. The above possible integrated battery 1 can be disposed in the vehicle chassis, and the cover of the integrated battery 700 is used as the vehicle floor to bear the self-weight of the vehicle body and the external trampling condition, realizing the integration of the battery and the vehicle body, reducing the weight of the whole vehicle, improving the battery space utilization rate, and reducing the use of vehicle 800 parts, reducing the cost of the whole vehicle to a certain extent. Further, since the integrated battery 700 can provide shock absorption and anti-impact protection, it can ensure the safe operation of the vehicle 800.

[0086] The vehicle provided by the embodiment of the present application integrates the battery as a whole in the vehicle chassis, uses the box cover as the vehicle floor, and directly integrates the battery module into the vehicle body structure, reducing the redundant vehicle structure, thereby releasing more space for the battery module, increasing the total battery capacity, and enabling it to more closely fill the available space inside the vehicle body, thus realizing the integration of the battery and the vehicle body.

[0087] In this specification, the embodiments or implementation manners are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
