[0055] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in multiple fields such as aerospace. With the continuous expansion of the application fields of power batteries, the market demand for them is also continuously increasing.

[0056] The battery device is used to be installed on an electrical device. Taking the electrical device as a vehicle as an example, for the reasonable weight distribution and safety requirements of the vehicle, the battery device is generally arranged at the bottom of the vehicle. At the same time, there are strict requirements for the height of the battery device from the ground to reduce the risk of the battery device colliding with the ground or the raised objects attached to the ground. This also limits the volume of the battery device. The volume of the battery device determines how many battery cells can be installed, that is, it determines the power of the battery device. The power of the battery device is related to the cruising range of the vehicle, which is also a hot topic that is highly concerned by those skilled in the art and consumers.

[0057] After careful research, the applicant found that the beam of the vehicle includes a main beam and a cross beam. The two ends of the cross beam are connected to the main beam to connect and strengthen it. The battery device is set under the cross beam. After further research, the applicant found that after some vehicles are installed, there is still some extra space on the top of the main beam, and there is still a distance between the cross beam and the top of the main beam. However, due to the setting of the cross beam, the interference between the battery device and the cross beam means that the battery device can only be set under the cross beam, resulting in a part of the space being unusable. The applicant thinks that if this part of the space can be reasonably used and the battery device can be made larger, the power of the battery device can be increased.

[0058] To this end, the applicant provides a new structural design of a battery device, the battery device includes a box body, a battery cell and a locking structure, the box body includes a body and a cover body, the body includes a bottom plate and a side panel surrounding the bottom plate, the bottom plate and the side panel cooperate to form a receiving groove, the cover body covers the opening of the receiving groove, the cover body includes a protrusion extending toward the side away from the body, the protrusion is provided with a mounting cavity, the mounting cavity and the receiving groove are both installed with a battery cell, and a reinforcing rib is provided on the side of the protrusion away from the body; the locking structure is provided on the cover body; and / or the locking structure is provided on the side of the side panel away from the receiving groove. The battery device can increase the volume of the box body, thereby increasing the power of the battery device.

The battery device 100 includes a box 10 and a battery cell 20, and the battery cell 20 is accommodated in the box 10. Among them, the box 10 is used to provide a storage cavity for the battery cell 20, and the box 10 can adopt a variety of structures. In some embodiments, the box 10 may include a cover 11 and a body 12, and the cover 11 and the body 12 cover each other, and the cover 11 and the body 12 jointly define a storage cavity for accommodating the battery cell 20. The body 12 can be a hollow structure with one end open, and the cover 11 can be a plate-like structure. The cover 11 covers the open side of the body 12, so that the cover 11 and the body 12 jointly define a storage cavity; the cover 11 and the body 12 can also be hollow structures with one side open, and the open side of the cover 11 covers the open side of the body 12. Of course, the box 10 formed by the cover 11 and the body 12 can be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0062] In the battery device 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 20 is accommodated in the box 10; of course, the battery device 100 may also be a battery module formed by connecting multiple battery cells 20 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the box 10. The battery device 100 may also include other structures, for example, the battery device 100 may also include a busbar component for realizing electrical connection between the multiple battery cells 20.

[0063] Each battery cell 20 may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0064] Reference Figure 3 According to some embodiments of the present application, the present application provides a battery device 100, including a box body 10, a battery cell 20 and a locking structure 30, the box body 10 includes a body 12 and a cover body 11, the body 12 includes a bottom plate and a side panel 121 surrounded by the bottom plate, the bottom plate and the side panel 121 are cooperated to form a receiving groove, the cover body 11 covers the opening of the receiving groove, the cover body 11 includes a protrusion 112 extending toward the side away from the body 12, an installation cavity is provided in the protrusion 112, the battery cell 20 is installed in the installation cavity and the receiving groove, and a reinforcing rib 113 is provided on the side of the protrusion 112 away from the body 12; the locking structure 30 is provided on the cover body 11; and / or, the locking structure 30 is provided on the side of the side panel 121 away from the receiving groove.

[0065] The main body 12 refers to the bottom part of the box body 10, and the cover body 11 refers to the upper part of the box body 10. When the battery device 100 is installed on the vehicle 1000. The main body 12 is arranged toward the ground, below the cover body 11. The main body 12 may include a bottom plate and a side panel 121. The side panel 121 is the side of the main body 12, which is an annular side panel, which may be a square side panel or a circular side panel, depending on the shape of the box body 10, and is generally square. The bottom plate may be the bottom surface of the main body 12, located at the bottom end of the box body 10. The main body 12 is formed with a recessed receiving groove, and the receiving groove is used to set the battery cell 20. The cover body 11 covers the opening of the receiving groove to close the opening. In an embodiment of the present application, the cover body 11 also includes a protrusion 112 extending toward a side away from the main body 12, and an installation cavity is formed in the protrusion 112, and a battery cell 20 can be set in the installation cavity. Refer to Figure 5 Taking the battery device 100 applied to the vehicle 1000 as an example, the battery device 100 is generally installed on a beam body, and the beam body includes two parallel main beams 50 and a plurality of cross beams 40 arranged along the length direction of the main beams 50. The two ends of the cross beam 40 are respectively connected to the two main beams 50, and a through hole 60 is arranged between two adjacent cross beams 40. Generally speaking, the battery device 100 cannot be made too high due to the height limit of the cross beam 40. In some models, the cross beam 40 cannot be set too high and needs to be set lower than the main beam 50. However, there is space in part of the position above the cross beam 40. Therefore, in this embodiment, a protrusion 112 is arranged on the cover body 11, and the protrusion 112 can extend into the vehicle body through the through hole 60, making full use of the space inside the vehicle 1000, so that the volume of the box body 10 can be increased, and more battery cells 20 can be accommodated, which is conducive to increasing the power of the battery device 100, and can also increase the energy density of the whole vehicle. At the same time, a locking structure 30 can be set on the cover body 11, or on the side panel 121, or on both the cover body 11 and the side panel 121. The battery device 100 is installed on the beam body through the locking structure 30, which facilitates the connection between the battery device 100 and the entire vehicle.

[0066] Generally, the cover 11 of the battery device 100 is disposed within the installation space 70 formed by the main beam 50 and the cross beam 40. The cross beam 40 can prevent other components of the vehicle body from colliding with the cover 11 from the top surface, and the main beam 50 can prevent other components of the vehicle body from colliding with the battery device 100, the side wall panel 121 and the cover 11 from the side. In the embodiments of the present application, the protruding portion 112 will protrude from the through hole 60 formed by the main beam 50 and the cross beam 40 and extend into the vehicle body interior. In this way, the interior space of the vehicle body can be fully utilized. However, there is also a risk that the protruding portion 112 is prone to collide with other components of the vehicle body. Therefore, a strengthening structure is provided on the surface of the protruding portion 112. The strengthening structure can be a reinforcing rib 113 or a reinforcing plate, which strengthens the protruding portion 112 and reduces the possibility of damage to the protruding portion 112 caused by collision. Specifically, the surface of the protruding portion 112 can be the outer surface of the protruding portion 112 facing away from the installation cavity, and the outer surface includes a top surface and a lateral surface.

[0067] By providing the protruding portion 112 on the cover 11, the space of the vehicle 1000 can be fully utilized, the power of the battery device 100 can be increased, and by providing the locking structure 30, it is convenient to install the battery device 100 on the vehicle 1000. In addition, by providing the reinforcing rib 113 on the protruding portion 112 to strengthen the protruding portion 112, the risk of damage to the protruding portion 112 caused by collision can be reduced.

[0068] Refer to Figure 3 , in some embodiments, the number of the protruding portions 112 is multiple, and the multiple protruding portions 112 are arranged at intervals along the first direction. Each protruding portion 112 extends along the second direction. The first direction is the length direction of the box body 10, and the second direction is the width direction of the box body 10.

[0069] It should be noted that the first direction of the present application refers to the length direction of the box body 10, which is also the length direction of the main beam 50 referred to later, as shown by the arrow X in Figure 3 , the width direction refers to the width direction of the box body 10, as shown by the arrow Y in Figure 3 , and the height direction refers to the vertical direction of the box body 10, as shown by the arrow Z in Figure 3 . The first direction, the second direction and the third direction are perpendicular to each other. Multiple protruding portions 112 can be provided according to the space surplus position of the vehicle 1000 to increase the volume of the battery device 100 to a greater extent. At the same time, the interval between two adjacent protruding portions 112 can be used to avoid the cross beam 40 or other structures of the vehicle 1000.

[0070] By providing multiple protruding portions 112, the interval between the protruding portions 112 is used to avoid the cross beam 40 or other structures, which is beneficial to increasing the volume of the battery device 100 to a greater extent according to the space structure of the vehicle 1000.

[0071] Reference Figure 3 , in some embodiments, the cover body 11 further includes a substrate 111, and the substrate 111 and the protrusion 112 are integrally formed.

[0072] The substrate 111 is a flat plate, and the protrusion 112 can be considered to be formed by the partial protrusion of the substrate 111 in the height direction away from the main body 12. Of course, the protrusion 112 can also be installed on the substrate 111 after the substrate 111 is manufactured. The integrally formed manufacturing method not only has a relatively simple manufacturing process, but also has fewer burrs between the substrate 111 and the protrusion 112, and the transition surface is relatively smooth, so it is not easy to cause scratches when installing the battery cell 20. The integrally formed manufacturing method can be blow molding and die casting.

[0073] By setting the substrate 111 and the protrusion 112 to be integrally formed, the manufacturing process is simple and the transition surface is smooth, which can reduce the possibility of damage to the battery cell 20.

[0074] Reference Figure 3 , in some embodiments, the locking structure 30 has a mounting hole 31, and a recess 114 is provided between any two adjacent protrusions 112, and the substrate 111 is provided with a mounting hole 31 corresponding to at least one recess 114.

[0075] As described above, the locking structure 30 can be provided on the cover body 11 or on the side wall plate 121. In this embodiment, the locking structure 30 provided on the cover body 11 is specifically described. There are a plurality of protrusions 112 provided on the cover body 11. The plurality can refer to two. The locking structure 30 can be provided on the substrate 111 between two adjacent protrusions 112, that is, the locking structure 30 is provided on the recess 114. Specifically, the locking structure 30 can be provided between each two adjacent protrusions 112, or the locking structure 30 can be provided on the substrate 111 between some two protrusions 112. Those skilled in the art can set it according to actual needs. Specifically, the locking structure 30 can be a mounting hole 31, and the mounting hole 31 can include a plurality of sub-holes. When the battery device 100 is installed on the beam body, the protrusion 112 passes through the through hole 60 between two adjacent cross beams 40, and the cross beam 40 is provided on the recess 114. Since the battery device 100 in the present application is provided with the protrusion 112, the height of the entire battery device 100 will be relatively large. Therefore, it can be locked at the top of the cover body 11. Specifically, the cross beam 40 and the mounting hole 31 on the cover body 11 of the battery device 100 can be connected by a threaded member 80, and the battery device 100 can be mounted on the beam body. In this way, the space of the recess 114 can be fully utilized. Of course, mounting holes 31 can also be provided at positions on the substrate 111 that do not correspond to the recesses 114, and they can also be connected to the cross beam 40 of the vehicle body by threaded members 80.

[0076] By arranging the mounting holes 31 on the recessed positions 114 between two adjacent convex portions 112, the cross beam 40 and the mounting holes 31 can be connected by threaded members 80 to lock the battery device 100 to the cross beam 40. In this way, the space of the recessed positions 114 can be fully utilized, and the installation is relatively convenient by adopting the top-mounted connection method.

[0077] In some embodiments, the interval between any two adjacent convex portions 112 is 250 mm to 320 mm.

[0078] Regarding the interval between two adjacent convex portions 112, if mounting holes 31 need to be arranged on the recessed positions 114 between the two convex portions 112, the interval between the two adjacent convex portions 112 needs to be able to accommodate the cross beam 40, that is, it needs to be greater than the width of the cross beam 40. At the same time, the positions of the convex portions 112 need to be considered to avoid interference with the cross beam 40 and other components of the vehicle body. According to actual measurement, by setting the width between two adjacent convex portions 112 to 250 mm to 320 mm, it can not only ensure no interference with the cross beam 40, but also set the convex portions 112 with a larger volume as much as possible to facilitate the installation of more battery cells 20. In addition, the height of the convex portion 112 in the height direction is 120 mm to 180 mm, and within this range, it can be set as large as possible to maximize the capacity of the battery device 100, but it should not be greater than 180 mm as much as possible, otherwise it is easy to interfere with other components of the vehicle 1000.

[0079] By setting a reasonable interval between two adjacent convex portions 112, the risk of interference between the cross beam 40 and the convex portions 112 can be reduced, the space of the vehicle body can be fully utilized, the volume of the battery device 100 can be increased, and thus it is beneficial to further increase the power of the battery device 100.

[0080] Refer to Figure 3 In some embodiments, the locking structure 30 includes a connecting plate 32 mounted on the side wall panel 121, and threaded holes 321 are provided on the connecting plate 32.

[0081] This embodiment describes an implementation manner of connecting with a beam body by arranging the locking structure 30 on the side wall panel 121. Specifically, the connecting plate 32 can be mounted on the side wall panel 121 in a fixed form, such as by welding; or it can be mounted on the side wall panel 121 in a movable connection form, such as by snap connection or threaded connection. Refer to Figure 5, threaded holes 321 are provided on the connecting plate 32 and are suitable for connecting with the beam body. The number of threaded holes 321 can be multiple, and the beam body and the threaded holes 321 can be connected by locking parts such as bolts or screws, so that the battery device 100 can be installed on the beam body. Specifically, it can be connected to the main beam 50, and in this way, the battery device 100 can be installed on the main beam 50 in the form of side attachment.

[0082] It should be noted that although this application describes two separate embodiments to illustrate the connection method between the battery device 100 and the beam body, that is, top attachment from the cover body 11 and side attachment from the side wall plate 121, those skilled in the art can understand that locking structures 30 can also be provided on both the cover body 11 and the side wall plate 121. While locking the cover body 11 to the cross beam 40, the connecting plate 32 is installed on the main beam 50 to achieve simultaneous attachment at two positions. In this way, the connection reliability is higher.

[0083] Refer to Figure 4 , in some embodiments, the side wall plate 121 is provided with a clamping strip 122, and the locking structure 30 has a clamping groove 322 provided on the connecting plate 32, and the clamping groove 322 is clamped with the clamping strip 122.

[0084] This embodiment describes the embodiment of setting the locking structure 30 on the side wall plate 121. Regarding the connection method between the locking structure 30 and the side wall plate 121, it can be a fixed connection, can be integrally formed during manufacturing, or can adopt a movable connection form, such as the matching structure of the clamping strip 122 and the clamping groove 322. Specifically, the clamping groove 322 is provided at a position on the side of the connecting plate 32 facing the side wall plate 121, and the clamping groove 322 is clamped with the clamping strip 122 to install the connecting plate 32 on the box body 10. Specifically, regarding the material of the clamping strip 122, a plastic part can be used, or a metal part with certain elasticity can be used. When using a metal part, it can be made of the same material as the box body 10. The material of the clamping groove 322 can also be made of a metal material with certain elasticity, such as a thinner steel sheet or copper sheet, so that it is convenient for installation and disassembly, and when it is necessary to change the side attachment position, the connecting plate 32 can be clamped to the corresponding position.

[0085] By setting the connection between the clamping strip 122 and the clamping groove 322 and adopting a movable connection method, it is convenient for the installation and disassembly of the connecting plate 32, and the connecting plate 32 can be installed at the corresponding position according to needs, improving the flexibility of installation.

[0086] Refer to Figure 4 , in some embodiments, the clamping strip 122 extends along a first direction, and the first direction is the length direction of the box body 10.

[0087] The first direction is the length direction of the box body 10. The clamping strip 122 extends along the first direction. A plurality of connecting plates 32 can be arranged on the clamping strip 122 for locking the box body 10 from different positions of the box body 10. At the same time, an entire clamping strip 122 is arranged along the length direction of the box body 10, and the position of the connecting plate 32 on the box body 10 can be adjusted to be applicable to the situation where the locking positions are different. For example, although the same battery device 100 is used for different types of vehicles 1000, the specific locking positions with the beam body are different. Therefore, the connection between the beam body and the battery device 100 can be realized by adjusting the position of the connecting plate 32.

[0088] By arranging the clamping strip 122 to extend along the length direction of the box body 10, a plurality of connecting plates 32 can be arranged on the clamping strip 122 for locking and fixing from different positions, thereby improving the reliability of the connection between the box body 10 and the beam body.

[0089] Refer to Figure 4 , in some embodiments, the number of the clamping strips 122 is two, and the two clamping strips 122 are arranged at intervals along the height direction of the box body 10. The number of the clamping grooves 322 is also two, and the two clamping grooves 322 are respectively arranged on both sides of the connecting plate 32 along the height direction of the box body 10, and the clamping grooves 322 are connected to the clamping strips 122 in one-to-one correspondence.

[0090] The number of the clamping strips 122 is two, and the two clamping strips 122 are arranged at intervals along the height direction of the box body 10. Two corresponding clamping grooves 322 are also arranged on the connecting plate 32, and the clamping grooves 322 are arranged on both sides of the connecting plate 32 along the height direction of the box body 10. For example, if the clamping strip 122 includes an upper sub-strip and a lower sub-strip, and the clamping groove 322 includes an upper sub-groove and a lower sub-groove, then the upper sub-groove is clamped on the upper sub-strip, and the lower sub-groove is clamped on the lower sub-strip. Since the battery device 100 generally has a large weight and there will inevitably be slight shaking during use, setting two clamping positions can make the connection between the connecting plate 32 and the box body 10 more reliable.

[0091] By setting the number of both the clamping strips 122 and the clamping grooves 322 to be two, the connecting plate 32 can be fixed from two positions, thereby improving the reliability of the connection.

[0092] In some embodiments, the installation cavity communicates with the accommodation groove.

[0093] It should be noted that regarding the setting of the convex portion 112, in a feasible embodiment, the cover body 11 can be a complete plate, and then the convex portion 112 is set on the cover body 11. Specifically, it can be connected by threads or welded. At this time, the battery cell 20 is arranged in the installation cavity of the convex portion 112, and the battery cell 20 is also arranged in the accommodation groove, and the accommodation groove and the installation cavity are not communicated.

Of course, some hole positions can be set for wire passing, so that the battery cell 20 in the installation cavity can be electrically connected to the battery cell 20 in the accommodation groove, and both can be connected to the high-voltage box of the box body 10. In another feasible embodiment, the convex portion 112 can be formed by the part of the cover body 11 protruding towards the through hole 60. The convex portion 112 is a part of the cover body 11 and can be integrally formed when the cover body 11 is manufactured, so that the manufacturing process can be simplified. At this time, the installation cavity and the accommodation groove are communicated. When installing the battery cell 20, it can be installed together according to the shapes of the installation cavity and the accommodation groove, so that it is not necessary to install multiple battery cells 20 in two times, and it is also more convenient to route wires or arrange other electrical components.

[0094] By setting the accommodation cavity and the installation cavity to be communicated, it is convenient to install multiple battery cells 20 together, and the assembly process is simplified.
