[0039] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 11 The embodiments of the present application are described in detail.
[0040] like Figures 1 to 10 As shown, the present application provides a battery 1, comprising a first battery module 11, a connector 12, and a top cover 13. The first battery module 11 comprises a first battery assembly 111 and a second battery assembly 112 spaced apart along a first direction X; the connector 12 is disposed between the first battery assembly 111 and the second battery assembly 112; and the top cover 13 covers the tops of the first battery assembly 111, the second battery assembly 112, and the connector 12, with the connector 12 being fixedly connected to the top cover 13.
[0041] The first battery module 11 includes a first battery assembly 111 and a second battery assembly 112 spaced apart along a first direction X. The first battery assembly 111 may be composed of one battery cell, or may be composed of multiple battery cells electrically connected in series, in parallel, or in a mixed manner (referring to multiple battery cells being connected in series and in parallel). Similarly, the second battery assembly 112 may also be composed of one or more battery cells. The battery cell may be a lithium-ion battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery, or a magnesium-ion battery, etc., which is not limited in the embodiments of the present application. The shape of the battery cell may be cylindrical, flat, rectangular, or other shapes, which is not limited in the embodiments of the present application.
[0042] The connector 12 is disposed between the first battery assembly 111 and the second battery assembly 112, that is, the connector 12 is disposed near the middle of the first battery module 11 along the first direction X. In existing batteries 11, the upper cover 13 is supported only at the ends. When the battery 11 is used in a vibrating environment, the further away the upper cover 13 is from the ends, the greater the vibration amplitude, the greater the deformation, and the greater the possibility of damage. Placing the connector 12 near the middle of the first battery module 11 along the first direction X provides support for the upper cover 13, increasing its rigidity at this location, reducing the vibration amplitude of the upper cover 13, and improving its service life.
[0043] Furthermore, in some embodiments, to improve the rigidity and insulation of the battery 1, a baffle is provided between the first battery assembly 111 and the second battery assembly 112. By disposing the connector 12 above the baffle between the first battery assembly 111 and the second battery assembly 112, the force of the connector 12 can be transmitted to the bottom plate of the battery 1 through the baffle, thereby not affecting the capacity of the battery 1 but also improving the service life of the battery 1.
[0044] The upper cover 13 covers the top of the first battery assembly 111, the second battery assembly 112 and the connector 12. Specifically, in some embodiments, the upper cover 13 is a plate-like structure, covering the top of the first battery assembly 111, the second battery assembly 112 and the connector 12; in other embodiments, the upper cover 13 includes a first surface corresponding to the top of the first battery assembly 111, the second battery assembly 112 and the connector 12 and at least one second surface adjacent to the first surface, that is, the upper cover 13 not only covers the top of the first battery assembly 111, the second battery assembly 112 and the connector 12, but also covers at least one side of the first battery assembly 111 and the second battery assembly 112 adjacent to the top.
[0045] The connector 12 is fixedly connected to the upper cover 13, that is, there is no relative motion between the connector 12 and the upper cover 13, and no relative movement occurs. Specifically, the fixed connection between the connector 12 and the upper cover 13 can be achieved through a non-detachable connection method such as bonding or welding, or through a detachable connection method such as bolt connection or snap connection, which is not limited in this embodiment of the present application. The connector 12 is fixedly connected to the upper cover 13, and the connector 12 provides support for the upper cover 13, increasing the rigidity of the upper cover 13 in this position, and preventing the upper cover 13 from vibrating, deforming, or even being damaged.
[0046] By arranging a connector 12 between the first battery assembly 111 and the second battery assembly 112 and fixing the connector 12 and the upper cover 13 together, on the one hand, the connector 12 does not occupy the space of the battery 1 and will not affect the capacity of the battery 1; on the other hand, during use, the connector 12 can provide support for the upper cover 13 near the middle of the battery 1 along the first direction X, thereby increasing the rigidity of the upper cover 13 and preventing the upper cover 13 from being deformed or even damaged due to vibration during use of the battery 1, thereby increasing the service life and reliability of the battery 1.
[0047] like Figure 3 and Figure 4As shown, in some embodiments, the first battery module 11 further includes a baffle 113 arranged between the first battery assembly 111 and the second battery assembly 112 along the first direction X, the connector 12 is arranged corresponding to the baffle 113, and one end of the connector 12 is connected to the first battery assembly 111 along the first direction X, and the other end is connected to the second battery assembly 112.
[0048] The baffle 113 is arranged between the first battery assembly 111 and the second battery assembly 112 along the first direction X. On the one hand, the first battery assembly 111 and the second battery assembly 112 can be separated in different accommodating chambers to prevent mutual influence between the two. For example, when the battery 1 fails and catches fire or the electrolyte leaks, the fire or electrolyte can be prevented from spreading to the other, thereby increasing the safety of the battery 1. On the other hand, the added baffle 113 can improve the strength of the battery 1, improve the extrusion and collision resistance of the battery 1, and improve the reliability of the battery 1.
[0049] Specifically, the number of baffles 113 can be one, disposed between the first battery assembly 111 and the second battery assembly 112 along the first direction X. The number of baffles 113 can also be two, disposed along the first direction X on a side of the first battery assembly 111 close to the second battery assembly 112 and on a side of the second battery assembly 112 close to the first battery assembly 111, respectively, to further enhance the strength of the battery 1.
[0050] In some embodiments, an insulating member is provided on the side of the baffle 113 near the battery assembly to improve the insulation performance of the battery 1. Specifically, the insulating member can be placed between the baffle 113 and the first battery assembly 111 or the second battery assembly 112, or can be adhered or coated on the side of the baffle 113 near the first battery assembly 111 or the second battery assembly 112.
[0051] The connector 12 is arranged corresponding to the baffle 113, that is, along the second direction Y, the connector 12 is arranged between the upper cover 13 and the baffle 113. The connector 12 can be connected to the bottom plate at the bottom of the battery 1 through the baffle 113, so that the supporting force provided by the connector 12 to the upper cover 13 is transmitted to the bottom plate at the bottom of the battery 1, thereby improving the stability of the upper cover 13, which does not affect the capacity of the battery 1 and can improve the service life of the battery 1.
[0052] One end of the connecting member 12 is connected to the first battery assembly 111 along the first direction X, and the other end is connected to the second battery assembly 112. That is, the first battery assembly 111 and the second battery assembly 112 are fixed to each other in the first direction X through the connecting member 12, which can further enhance the stability of the first battery module 11.
[0053] like Figure 4 and Figures 7 to 10As shown, in some embodiments, a support portion 121 is provided on one side of the connector 12 close to the upper cover 13 . The support portion 121 is a convex portion protruding from the connector 12 , and the surface of the support portion 121 close to the upper cover 13 is fitted with the upper cover 13 .
[0054] The support portion 121 is set as a protrusion on the connecting member 12. On the one hand, when the support portion 121 is fitted with the upper cover 13, other positions on the connecting member 12 can be avoided to ensure the accuracy of the fixed connection between the connecting member 12 and the upper cover 13; on the other hand, during processing, only the support portion 121 can be fine-processed, which can reduce the processing area and improve the processing speed.
[0055] like Figure 8 and Figure 9 As shown, in some embodiments, the support portion 121 is extended along the first direction X.
[0056] Extending the support portion 121 along the first direction X can increase the size of the support portion 121 in the first direction X, increase the supporting area of the connector 12 on the upper cover 13 , improve the supporting effect, and enhance the stability of the upper cover 13 .
[0057] like Figure 8 and Figure 9 As shown, in some embodiments, the support portion 121 is a hollow structure, and the hollow structure extends along the first direction X.
[0058] The support portion 121 is a hollow structure. It should be noted that the cross-section of the hollow structure can be a regular shape such as a circle or a square, or it can be an irregular shape composed of straight lines and / or curves. The embodiment of the present application does not limit this.
[0059] Providing the support portion 121 with a hollow structure can save material costs while reducing the weight of the battery 1 and improving the practicality of the battery 1 .
[0060] like Figure 2 and Figures 5 to 7 As shown, in some embodiments, the connecting member 12 and the upper cover 13 are connected by bolts 14 .
[0061] Specifically, a threaded hole may be made on the connecting member 12 , and then the connecting member 12 and the upper cover 13 are fixedly connected by connecting the bolt 14 with the threaded hole.
[0062] like Figure 7 As shown, in some embodiments, a seal 15 is provided between the connector 12 and the upper cover 13 and / or a gasket 16 is provided between the bolt 14 and the upper cover 13 .
[0063] Specifically, in some embodiments, a seal 15 is provided between the connector 12 and the upper cover 13. The seal 15 may be a component made of rubber. The provision of the seal 15 can improve the sealing of the battery 1. On the one hand, it can improve the waterproofness of the battery 1. On the other hand, it can isolate the air, reduce or delay the spread of fire after the battery 1 catches fire, and improve the safety of the battery 1. In other embodiments, a gasket 16 is provided between the bolt 14 and the upper cover 13. The gasket 16 can increase the force-bearing area between the bolt 14 and the upper cover 13, disperse the pressure applied by the bolt 15 on the upper cover 13, and protect the upper cover 13. In still other embodiments, a seal 15 is provided between the connector 12 and the upper cover 13, and a gasket 16 is provided between the bolt 14 and the upper cover 13, which can simultaneously improve the sealing of the battery 1 and protect the upper cover 13.
[0064] like Figure 7 As shown, in some embodiments, a gasket 16 is provided between the bolt 14 and the upper cover 13, and the surface of the upper cover 13 facing away from the connecting member 12 is recessed inward to form a first recessed portion 131, and the bolt 15 and the gasket 16 are accommodated in the first recessed portion 131; and / or a sealing member 15 is provided between the connecting member 12 and the upper cover 13, and a gasket 16 is provided between the bolt 15 and the upper cover 13, and the surface of the support portion 121 close to the upper cover 13 is recessed inward to form a second recessed portion 1211, and the sealing member 15 is accommodated in the second recessed portion 1211, and the projection of the gasket 16 along the second direction Y covers the second recessed portion 1211, and the second direction Y is perpendicular to the first direction X.
[0065] In some embodiments, the surface of the upper cover 13 facing away from the connector 12 is recessed inward to form a first recessed portion 131. Accommodating the bolt 15 and the gasket 16 in the first recessed portion 131 can prevent the bolt 15 and the gasket 16 from protruding from the upper cover 13, thereby preventing the bolt 15 and the gasket 16 from interfering with other parts during the assembly process, thereby affecting the safety of the battery 1.
[0066] In other embodiments, the surface of the support portion 121 adjacent to the upper cover 13 is recessed inward to form a second recess 1211. Providing the second recess 1211 to accommodate the seal 15 prevents the seal 15 from occupying additional space within the battery 1, thereby affecting the energy density of the battery 1. In this case, if a gasket 16 is provided between the bolt 15 and the upper cover 13, it is necessary to ensure that the projection of the gasket 16 along the second direction Y covers the second recess 1211. In other words, the size of the gasket 16 must be larger than that of the second recess 1211. This ensures that the gasket 16 rests against the support portion 121 during assembly rather than falling into the second recess 1211. This ensures that the gasket 16 abuts against the support portion 121 after assembly, thereby increasing the connection strength of the bolt 15 while maintaining the support force of the upper cover 13.
[0067] like Figure 1 、 Figure 3 and Figure 4 As shown, in some embodiments, the battery 1 also includes a second battery module 17 arranged on one side of the first battery module 11 along the third direction Z, the second battery module 17 includes a third battery assembly 171 and a fourth battery assembly 172 arranged at intervals along the first direction X, one end of the connector 12 is connected to the first battery assembly 111 and the third battery assembly 171, and the other end is connected to the second battery assembly 12 and the fourth battery assembly 172, and the third direction Z is perpendicular to the first direction X and the second direction Y.
[0068] Similarly, the third battery assembly 171 and the fourth battery assembly 172 may also be composed of one or more battery cells. The battery cells may also be lithium-ion batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and are not limited in this embodiment of the present application. The battery cells may also be cylindrical, flat, rectangular, or other shapes, and are not limited in this embodiment of the present application.
[0069] It should be noted that the first battery assembly 1 , the second battery assembly 2 , the third battery assembly 171 and the fourth battery assembly 172 may be composed of the same battery cells or different battery cells.
[0070] One end of the connecting member 12 is connected to the first battery assembly 111 and the third battery assembly 171, and the other end is connected to the second battery assembly 12 and the fourth battery assembly 172. That is, the connecting member 12 is arranged between the first battery assembly 1, the second battery assembly 2, the third battery assembly 171 and the fourth battery assembly 172, and connects the four battery assemblies in the front, back, left and right directions, thereby improving the overall stability of the battery 1 and supporting the upper cover 13, thereby improving the stability of the upper cover.
[0071] It should be noted that the number of battery modules and battery assemblies in this application is not limited to two as described in the embodiments of this application, that is, the number of battery modules and battery assemblies can be increased as needed, and it is only necessary to set the corresponding connectors 12 according to the above embodiments.
[0072] like Figure 11 As shown, the present application provides an electrical device on the other hand, the electrical device includes a battery 1, and the battery 1 is used to provide electrical energy.
[0073] Electrical equipment can be vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and electric tools, etc. Vehicles can be fuel vehicles, gas vehicles, or new energy vehicles. New energy vehicles can be pure electric vehicles, hybrid vehicles, or extended-range vehicles, etc. Spacecraft include airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Electric tools include metal cutting electric tools, grinding electric tools, assembly electric tools, and railway electric tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, etc. The embodiments of the present application do not impose any special restrictions on the above-mentioned electrical equipment.
[0074] For the convenience of description, the following embodiments are described by taking a vehicle as an example of an electrical device.
[0075] like Figure 11 As shown, the vehicle includes a battery 1, which can be installed at the bottom, front or rear of the vehicle. Battery 1 can not only serve as the operating power source of the vehicle, but also as the driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.
[0076] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
