DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0029] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0031] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0032] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0033] The term "plurality" used in this application refers to two or more (including two).

[0034] In this application, a battery can be a battery cell or a battery module, wherein a battery cell can include a lithium-ion secondary battery, a lithium-ion primary 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 this application. A battery cell can be cylindrical, flat, rectangular, or in other shapes, etc., which is not limited in the embodiments of this application. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells, and soft-pack battery cells, which is not limited in the embodiments of this application.

[0035] A battery cell may include a housing, an electrode assembly, and an electrolyte. The housing is used to hold the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer. The positive electrode active material layer is coated on the surface of the positive electrode collector. The positive electrode collector not coated with the positive electrode active material layer protrudes from the positive electrode collector coated with the positive electrode active material layer. The positive electrode collector not coated with the positive electrode active material layer serves as the positive electrode tab. Taking lithium-ion batteries as an example, the material of the positive electrode collector can be aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode sheet consists of a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector. The negative current collector uncoated with the negative active material layer protrudes from the negative current collector coated with the negative active material layer. The negative current collector uncoated with the negative active material layer serves as the negative electrode tab. The negative current collector can be made of copper, and the negative active material can be carbon, silicon, or other materials. To ensure that high currents can pass without melting, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together.

[0036] The material of the isolation film may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a wound structure or a laminated structure, but the embodiments of the present application are not limited thereto.

[0037] In recent years, new energy vehicles have developed by leaps and bounds. In the field of electric vehicles, power batteries, as the power source of electric vehicles, play an irreplaceable and important role.

[0038] Some existing chassis structures for new energy vehicles integrate batteries directly into the chassis. This increases battery installation space, allowing for the installation of more batteries. The batteries, as part of the chassis, enhance structural strength while reducing the weight of chassis components, ultimately improving vehicle range. However, this chassis structure makes traditional seat installation arrangements ineffective.

[0039] Based on the above considerations, in order to solve the problem that the seat installation arrangement cannot be effectively implemented in a chassis structure with an integrated battery, the present application discloses a chassis, comprising: a chassis body and a seat mounting structure, wherein the chassis body comprises a first crossbeam, a first longitudinal beam, a second longitudinal beam, and a battery, wherein the first longitudinal beam and the second longitudinal beam are connected to the first crossbeam, and the first longitudinal beam, the second longitudinal beam and the first crossbeam define a storage space, and the battery is disposed in the storage space; and the seat mounting structure is located above the battery, and the seat mounting structure comprises a second crossbeam, which connects the first longitudinal beam and the second longitudinal beam.

[0040] In this chassis structure, the chassis body includes a first crossbeam, a first longitudinal beam, a second longitudinal beam, and a battery, allowing the battery to be integrated into the chassis body. The seat mounting structure includes a second crossbeam, which connects the first and second longitudinal beams. The second crossbeam, the first and second longitudinal beams form an I-shaped structure, which improves the overall strength and rigidity of the chassis, as well as the torsional rigidity of the chassis, thereby enhancing battery reliability. Because the second crossbeam connects the first and second longitudinal beams, the seat mounting structure is connected to the beams of the chassis body, facilitating the installation of seats within the battery-integrated chassis structure and facilitating efficient implementation of the seat mounting arrangement.

[0041] For the convenience of description, the following embodiments are described by taking a vehicle 1000 according to an embodiment of the present application as an example.

[0042] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 is a pure electric vehicle, a hybrid vehicle, an extended-range vehicle, etc. In the vehicle 1000, a battery 104 is integrated inside the chassis 100. The battery 104 can be used to power the vehicle 1000. For example, the battery 104 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 104 to power the motor 300, for example, for starting, navigating, and meeting the power requirements of the vehicle 1000 during operation.

[0043] In some embodiments of the present application, the battery 104 can serve not only as an operating power source for the vehicle 1000 , but also as a driving power source for the vehicle 1000 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000 .

[0044] Battery 104 may include multiple battery cells, which may be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of series and parallel connections. Multiple battery cells may be directly connected in series, in parallel, or in a hybrid configuration, and the entire structure of the multiple battery cells may then be housed within chassis 100. Alternatively, battery 104 may be constructed by first connecting multiple battery cells in series, in parallel, or in a hybrid configuration to form a battery module, which is then connected in series, in parallel, or in a hybrid configuration to form a single unit housed within chassis 100. Battery 104 may also include other structures, such as a busbar assembly for electrically connecting the multiple battery cells.

[0045] Each battery cell can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell can be cylindrical, flat, rectangular, or in other shapes. For example, the battery cell can be cylindrical.

[0046] 2 and 3 , an embodiment of the present application provides a chassis 100 comprising a chassis body 10 and a seat mounting structure 20. The chassis body 10 comprises a first crossbeam 101, a first longitudinal beam 102, a second longitudinal beam 103, and a battery 104. The first longitudinal beam 102 and the second longitudinal beam 103 connect the first crossbeam 101. The first longitudinal beam 102, the second longitudinal beam 103, and the first crossbeam 101 define a storage space 10a, within which the battery 104 is disposed. The seat mounting structure 20 is located above the battery 104 and comprises a second crossbeam 201, which connects the first longitudinal beam 102 and the second longitudinal beam 103.

[0047] The chassis body 10 may refer to the main structure of the chassis 100. The first cross member 101 may refer to a member extending along the width direction (the second direction Y in FIG. 3 ) of the chassis 100. The first longitudinal member 102 and the second longitudinal member 103 may refer to members extending along the length direction (the first direction X in FIG. 3 ) of the chassis 100.

[0048] The first longitudinal beam 102 and the second longitudinal beam 103 connect to the first cross beam 101 to form an I-shaped or □-shaped structure, which has good strength and rigidity and can form an accommodation space 10a, in which the battery 104 can be located. It can be understood that the battery 104 is integrated into the I-shaped or □-shaped structure. The first cross beam 101, the first longitudinal beam 102, the second longitudinal beam 103, and the battery 104 collectively form an "energy cabin" that can provide energy for the vehicle 1000. This makes the chassis body 10 similar to a CTC chassis, reducing the number of parts and the assembly process, thereby lowering costs.

[0049] The battery 104 and the I-shaped frame structure or the D-shaped structure may at least partially overlap in height. This means that the top of the battery 104 does not extend beyond the tops of the first longitudinal beam 102, the second longitudinal beam 103, and the first transverse beam 101, while the bottom of the battery 104 may extend beyond the bottoms of the first longitudinal beam 102, the second longitudinal beam 103, and the first transverse beam 101; alternatively, the top of the battery 104 does not extend beyond the tops of the first longitudinal beam 102, the second longitudinal beam 103, and the first transverse beam 101, while the bottom of the battery 104 does not extend beyond the bottoms of the first longitudinal beam 102, the second longitudinal beam 103, and the first transverse beam 101. The top and bottom of the battery 104, the first longitudinal beam 102, the second longitudinal beam 103, and the first transverse beam 101 may refer to the two ends of the third direction Z in Figure 2 or Figure 3.

[0050] The battery 104 may be, but is not limited to, a battery cell, a battery cell, a battery module, a battery pack, etc. For example, the first longitudinal beam 102 and the second longitudinal beam 103 may be door sill beams.

[0051] The seat mounting structure 20 may be, but is not limited to, one or more. For example, when the vehicle 1000 has two seats, one seat mounting structure 20 is provided; when the vehicle 1000 has five seats, two seat mounting structures 20 may be provided; and when the vehicle 1000 has seven seats, three seat mounting structures 20 may be provided.

[0052] The seat mounting structure 20 may be a structure used to mount the seat to the chassis body 10. The seat mounting structure 20 includes a second crossbeam 201, which connects the seat mounting structure 20 to the beams of the chassis body 10, facilitating the installation of the seat within the chassis 100, which incorporates the battery 104. Furthermore, because the second crossbeam 201 connects the first longitudinal beam 102 and the second longitudinal beam 103, the second crossbeam 201, the first longitudinal beam 102, and the second longitudinal beam 103 form an I-shaped structure. This I-shaped structure offers excellent stability and strength, thereby enhancing the strength and rigidity of the energy compartment.

[0053] In the above technical solution, the chassis body 10 is configured to include a first crossbeam 101, a first longitudinal beam 102, a second longitudinal beam 103 and a battery 104, the first longitudinal beam 102 and the second longitudinal beam 103 are connected to the first crossbeam 101, the first longitudinal beam 102, the second longitudinal beam 103 and the first crossbeam 101 define an accommodation space 10a, and the battery 104 is arranged in the accommodation space 10a. The battery 104 can be integrated into the chassis body 10. On this basis, the seat mounting structure 20 is arranged on the upper side of the battery 104, and the seat mounting structure 20 includes a second crossbeam. Beam 201, the second cross beam 201 connects the first longitudinal beam 102 and the second longitudinal beam 103, and the seat mounting structure 20 can be connected to the beam body of the chassis 100 through the second cross beam 201, which is beneficial to the seat installation arrangement in the chassis structure of the integrated battery 104, and the seat mounting structure 20 can not only play the role of installing the seat, but also improve the strength and rigidity of the area where the battery 104 is located in the chassis body 10 through the second cross beam 201, which can improve the overall strength and rigidity of the chassis 100, and improve the torsional rigidity of the chassis 100, thereby improving the reliability of the battery 104.

[0054] In some embodiments of the present application, referring to Figures 2, 3 and 4, the seat mounting structure 20 further includes a first support member 202 and a seat mounting plate 203, the first support member 202 is connected to the second cross beam 201; the seat mounting plate 203 is connected to the first support member 202.

[0055] The seat mounting plate 203 can play the role of installing the seat. The first support member 202 can play a supporting role to the seat mounting plate 203 and can fix the seat mounting plate 203 on the chassis body 10 by connecting the second crossbeam 201.

[0056] In the above technical solution, the first support member 202 and the seat mounting plate 203 can provide a seat mounting position. At the same time, since the first support member 202 connects the second cross beam 201 and the seat mounting plate 203, it can be seen that the second cross beam 201 can not only improve the strength and rigidity of the area where the battery 104 is located on the chassis body 10, but also provide a connection position for the first support member 202, which is beneficial to the installation of the seat on the chassis body 10.

[0057] In some embodiments of the present application, the first support member 202 may be a sheet metal member. It can be understood that the first support member 202 is a support plate having a large support surface, good support strength and rigidity, which is conducive to improving the support stability of the seat mounting plate 203.

[0058] In some embodiments of the present application, the first support member 202 and the second beam 201 may be connected in a manner including, but not limited to, welding, riveting, and screwing.

[0059] In some embodiments of the present application, referring to FIG. 2 and FIG. 3 , the seat mounting structure 20 further includes a second support member 204 , which connects the first cross beam 101 and the seat mounting plate 203 .

[0060] The second support member 204 supports the seat mounting plate 203 and, by connecting to the first cross member 101, secures the seat mounting plate 203 to the chassis body 10. As previously mentioned, the second support member 204 and the first support member 202 can support the seat mounting plate 203 at two locations. For example, the first support member 202 can support the front portion of the seat mounting plate 203, while the second support member 204 can support the rear portion of the seat mounting plate 203 (the front and rear portions of the seat mounting plate 203 may refer to the two ends in the first direction X of FIG. 2 ).

[0061] In the above technical solution, the seat mounting plate 203, the first support member 202, the second support member 204, the first crossbeam 101 and the second crossbeam 201 can form a rectangular frame structure with high strength and rigidity, so that the seat mounting structure 20 has high stability and can improve the reliability of seat installation.

[0062] In some embodiments of the present application, the second support member 204 may be a sheet metal member. It can be understood that the second support member 204 is a support plate having a large support surface, good support strength and rigidity, which is conducive to improving the support stability of the seat mounting plate 203.

[0063] In some embodiments of the present application, the second support member 204 and the first beam 101 are connected by, but not limited to, welding, riveting, screwing, and the like.

[0064] In some embodiments of the present application, referring to FIG. 3 , the second support member 204 and the first support member 202 extend along the length direction of the first beam 101 .

[0065] The length direction of the first crossbeam 101 can be the second direction Y in Figure 3. In this technical solution, the first support member 202 and the second support member 204 have a large length, which can increase the length of the support area for the seat mounting plate 203, improve the support stability of the seat mounting plate 203, and thus improve the reliability of seat installation.

[0066] In some embodiments of the present application, referring to FIG. 2 and FIG. 3 , the seat mounting structure 20 further includes a third cross beam 205 , which connects the second support member 204 and the seat mounting plate 203 .

[0067] The third beam 205 may refer to a beam body extending along the length direction of the first beam 101. Referring to Figures 2 and 3, the third beam 205 extends along the second direction Y.

[0068] In the above technical solution, the third cross beam 205 and the second support member 204 are jointly connected to the seat mounting plate 203. On the basis of the second support member 204 supporting the seat mounting plate 203, the third cross beam 205 can also play the role of supporting the seat mounting plate 203, further improving the reliability of the seat mounting structure 20.

[0069] In some embodiments of the present application, referring to FIG. 3 , the seat mounting structure 20 further includes a seat belt bracket 206 , which connects the second support member 204 and the third cross beam 205 .

[0070] The seatbelt bracket 206 is used to provide a seatbelt installation location. In this technical solution, the seatbelt bracket 206 connects the second support member 204 and the third crossbeam 205. The seatbelt bracket 206 can improve the connection strength and rigidity between the second support member 204 and the third crossbeam 205. Moreover, because the second support member 204 and the third crossbeam 205 are both perpendicular to the seatbelt bracket 206, the second support member 204, the third crossbeam 205, and the seatbelt bracket 206 form a horizontal and vertical cross structure, which has higher overall structural strength and better stability. This can improve the support for the seat mounting plate 203 and enhance the overall reliability of the seat mounting plate 203.

[0071] In some embodiments of the present application, there may be one or more seatbelt brackets 206. For example, referring to FIG3 , there are two seatbelt brackets 206 , spaced apart along the length of the third crossbeam 205 . In this technical solution, as previously described, due to the large number of seatbelt brackets 206 , the seatbelt brackets 206 , the second support member 204 , and the third crossbeam 205 can form a more cross-sectional and vertical structure, further improving the strength and reliability of the connection between the second support member 204 and the third crossbeam 205 .
