[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0033] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0036] In this application, "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0037] Currently, the rear floor and spare tire compartment areas are mostly constructed of sheet metal. Components need to be fixed to these areas using mounting brackets. The use of mounting brackets increases the overall vehicle material cost, and the mold making, logistics, and management of these brackets also incur costs, hindering cost control. Excessive use of mounting brackets can negatively impact the aesthetics of the structural design and increase design and management complexity.

[0038] In addition, during final assembly, the components located inside and outside the rear floor and spare tire pit are all manually transported to the main assembly line, lifted to the corresponding area of ​​the vehicle body, and secured, which increases employee fatigue.

[0039] In view of this, this application provides a vehicle that can reduce human fatigue, improve assembly efficiency, and reduce costs.

[0040] This application provides a vehicle, with reference to... Figures 1 to 4The vehicle includes a body-in-white 1, a rear floor 2, and a plurality of first fasteners 3. The rear floor 2 is located on the rear side of the body-in-white 1. Along the circumference of the rear floor 2, the rear floor 2 is provided with a plurality of spaced first mounting holes 20. Each first fastener 3 passes through the corresponding first mounting hole 20 and is connected to the body-in-white 1 so that the rear floor 2 and the body-in-white 1 can be detachably connected.

[0041] The rear floor 2 is located behind the body-in-white 1 and serves as the area for storing the spare tire and luggage compartment. Components such as the 12V battery 7 and PDU module can be mounted on the rear floor 2. The rear floor 2 is detachably connected to the body-in-white 1 via a first fastener 3. This allows the 12V battery 7, PDU module, and other components to be integrated and installed onto the rear floor 2 on a small assembly line. Then, the integrated rear floor 2 is transported as a whole to the main assembly line via an automated transfer device on the assembly line. From there, the rear floor 2 is lifted onto the body-in-white 1 by a lifting device on the main assembly line and detachably connected to it. This eliminates the need for welding, reduces manual labor, and simplifies the assembly process on the main assembly line, improving efficiency. For example, the first fastener 3 can be a bolt and nut structure, such as a bolt passing through the rear floor 2 and the body-in-white 1 and then being secured with a nut, thus achieving a detachable connection between the rear floor 2 and the body-in-white 1.

[0042] Optionally, the rear floor 2 is constructed of plastic. The rear floor 2 is formed by injection molding. The strength of the rear floor 2 after molding can be adjusted by adjusting the material thickness, ribs, etc. during the injection molding process. The injection molding process can also be used to set mounting grooves 24, mounting holes, etc. on the rear floor 2 so that various components can be directly installed on the rear floor 2, thereby reducing the use of mounting brackets, reducing mold development costs, and reducing material costs.

[0043] Optionally, refer to Figure 4 The rear floor 2 is provided with multiple thin sections 21, which are spaced apart along the longitudinal direction of the vehicle. The thin sections 21 can be thickness-reducing areas on the rear floor 2, which can be continuous or spaced apart. The thin sections 21 can also be grooves or through holes on the rear floor 2, which can be continuous or spaced apart. The extension direction of the thin sections 21 can be parallel to the lateral direction of the vehicle.

[0044] When the vehicle is involved in a collision, the rear floor 2 will break at the weak point 21 after being squeezed. The corresponding parts can be removed from their installation positions and offset to avoid collisions, thereby reducing the hard contact or hard compression between the parts and other parts on the rear floor 2. This reduces the risk of impact fracture and fire, while also reducing damage to parts and saving a lot of maintenance costs.

[0045] It should be understood that the weak part 21 can be constructed as a long strip or an arc shape, etc. The specific shape of the weak part 21 is not limited in this application, as long as the weak part 21 can break after the rear floor 2 is compressed, thereby reducing the compression or collision between the components on the rear floor 2.

[0046] Optionally, refer to Figure 3 and Figure 4 The vehicle also includes a seal 4, which is located between the body-in-white 1 and the rear floor 2 along the vertical direction of the vehicle.

[0047] The seal 4 seals the space between the body-in-white 1 and the rear floor 2, reducing the surface gap between them and isolating the passenger compartment from the outside, forming a waterproof barrier to reduce the ingress of external water into the vehicle. For example, the seal 4 may be a structure such as a sealing sponge.

[0048] Optionally, refer to Figure 1 and Figure 4 The vehicle also includes a power distribution module 5 and a plurality of second fasteners. The power distribution module 5 has a plurality of second mounting holes 51, and the rear floor 2 is provided with a plurality of first mounting bosses 22. Each second fastener (not shown in the figure) passes through the corresponding second mounting hole 51 and is connected to the corresponding first mounting boss 22.

[0049] The power distribution module (PDU module) 5 is used to distribute the DC voltage output by the power supply according to the voltage requirements of different components of the vehicle.

[0050] Multiple first mounting bosses 22 may protrude from the surface of the rear floor 2 and have internally embedded nuts and sleeves, so that the second fastener passes through the corresponding second mounting hole 51 on the second power distribution module 5 and is threadedly connected to the corresponding first mounting boss 22. This reduces the use of mounting brackets when fixing the power distribution module 5 and lowers material costs. The position and number of the multiple first mounting bosses 22 can be determined according to the position and number of the second mounting holes 51 on the power distribution module 5, so that the power distribution module 5 can be stably fixed on the rear floor 2.

[0051] Optionally, refer to Figure 1 and Figure 4 The vehicle also includes a power module 6 and multiple third fasteners (not shown in the figure). The power module 6 has multiple third mounting holes (not shown in the figure), and the rear floor 2 is provided with multiple second mounting bosses 23. Each third fastener passes through the corresponding third mounting hole and connects to the corresponding second mounting boss 23.

[0052] The power module (DCDC module) 6 converts AC power to DC power during vehicle battery charging. Multiple second mounting bosses 23 may protrude from the surface of the rear floor 2 and have internally embedded nuts or sleeves, allowing third fasteners to pass through corresponding third mounting holes on the power module 6 and connect with the corresponding second mounting boss 23 via threaded engagement. This reduces the need for mounting brackets when fixing the power module 6, lowering material costs. The location and number of the multiple second mounting bosses 23 can be determined based on the location and number of third mounting holes on the power module 6, ensuring the power module 6 is stably fixed to the rear floor 2.

[0053] Optionally, refer to Figure 1 and Figure 4 The vehicle also includes a battery 7, and a mounting slot 24 for accommodating the battery 7 is provided on the rear floor 2. The battery 7 is used to power the vehicle's low-voltage system. The mounting slot 24 is integrally molded onto the rear floor 2 by injection molding, and the battery 7 is installed in the mounting slot 24, which provides physical protection for the battery 7.

[0054] Optionally, refer to Figure 6 The rear floor 2 is also equipped with a storage compartment 25. The recessed storage compartment 25 is set on the rear floor 2 through injection molding process, thereby increasing the storage space on the rear floor 2 and improving the overall storage level of the vehicle.

[0055] Optionally, refer to Figure 1 and Figure 2 The vehicle also includes an air compressor 11, which is located on the rear floor 2. The air compressor 11 is a supply component for the air suspension system. It can be located in other possible positions such as under the rear floor 2, on the left, or on the right.

[0056] Optionally, refer to Figure 1 and Figure 2 The vehicle also includes an oxygen generator 8, an air tank 9, and an oxygen compressor 10. The oxygen generator 8 is connected between the oxygen compressor 10 and the air tank 9 via an air pipe. The oxygen generator 8, the air tank 9, and the oxygen compressor 10 are all located on the rear floor 2.

[0057] An oxygen generator 8, an air tank 9, and an oxygen compressor 10 are installed on the rear floor 2 to realize the oxygen production function of the vehicle. The specific installation positions of the oxygen generator 8, air tank 9, and oxygen compressor 10 on the rear floor 2 can be determined according to the specific usage scenario. This application is not limited to any specific location as long as the oxygen production function can be realized.

[0058] Optionally, refer to Figure 5The vehicle also includes multiple fourth fasteners and multiple fifth fasteners. The rear floor 2 is provided with multiple fourth mounting holes 27. The lower side of the rear floor 2 is provided with multiple third mounting bosses 26. The air tank 9 has multiple fifth mounting holes. Each fourth fastener passes through the corresponding fourth mounting hole 27 to fix the oxygen generator 8 to the upper side of the rear floor 2. Each fifth fastener passes through the corresponding fifth mounting hole and is fixed to the corresponding third mounting boss 26.

[0059] Multiple third mounting bosses 26 may protrude from the surface of the rear floor 2 and have internally embedded nuts and sleeves, allowing the fifth fastener to pass through the corresponding fifth mounting hole on the air tank 9 and connect with the corresponding third mounting boss 26 via threaded engagement. This reduces the use of mounting brackets when fixing the air tank 9 and lowers material costs. The location and number of the multiple third mounting bosses 26 can be determined based on the location and number of the fifth mounting holes on the air tank 9, ensuring that the air tank 9 can be stably fixed to the rear floor 2. The number of air tanks 9 can be multiple.

[0060] Each fourth mounting hole 27 extends through the rear floor 2 along the vertical direction of the vehicle. A fourth fastener, such as a bolt, passes through the fourth mounting hole 27 to fix the oxygen generator 8 to the rear floor 2. The location and number of the multiple fourth mounting holes 27 can be determined according to the location and number of mounting holes on the oxygen generator so that the oxygen generator 8 can be stably fixed to the rear floor 2.

[0061] It should be noted that in this application, the oxygen generator 8, the gas storage tank 9, the power module 6, and the power distribution module 5 can be connected to the mounting holes on the rear floor 2 or to the mounting bosses via bolts or other fasteners, depending on the specific application requirements.

[0062] In one embodiment of this application, along the left-right direction of the vehicle, the rear floor 2 includes a first area and a second area. A battery 7, a power distribution module 5, and a power module 6 are located in the first area. Along the left-right direction of the vehicle, the power module 6 is located to the right of the battery 7. Along the front-rear direction of the vehicle, the power distribution module 5 is located behind the battery 7. An oxygen concentrator 8 and an air tank 9 are located in the second area. The oxygen concentrator 8 is located on the upper side of the second area, and the air tank 9 is located on the lower side of the second area. Multiple air tanks 9 may be arranged side-by-side on the lower side of the second area. An oxygen compressor 10 may be located on the left side of the rear floor 2 or other suitable locations, and an air compressor 11 may be located on the right side of the rear floor 2 or other suitable locations.

[0063] In another embodiment, along the left-right direction of the vehicle, the rear floor 2 includes a first area and a second area. The battery 7, power distribution module 5, and power module 6 are located in the first area. Along the left-right direction of the vehicle, the power module 6 is located to the right of the battery 7, and along the front-rear direction of the vehicle, the power distribution module 5 is located behind the battery 7. If the vehicle model does not have an oxygen generation function, components such as the oxygen generator 8, oxygen compressor 10, and air tank 9 can be omitted. Therefore, the second area can be set as a sunken storage compartment 25, which can contribute approximately 300L of storage space, significantly improving the overall storage capacity of the vehicle.

[0064] It should be understood that the specific structural form of the rear floor 2 in this application, as well as the specific installation positions of each component, can be arranged differently according to the specific vehicle configuration, and this application is not limited thereto.

[0065] In this application, the rear floor 2 is changed from being welded to the body-in-white 1 from a sheet metal part to a plastic part screwed to the body-in-white 1. By setting mounting holes and mounting bosses on the rear floor 2, components such as the battery 7, PDU module, DC-DC module, oxygen generator 8, air tank 9, oxygen compressor 10, and air compressor 11 can be directly fixed to the rear floor 2. This reduces the need for mounting brackets and reinforcing plates on the rear floor 2, saving on mold development and material costs. It also enables the assembly and integration of components such as the battery 7, PDU module, DC-DC module, oxygen generator 8, air tank 9, oxygen compressor 10, and air compressor 11 with the rear floor 2 on the assembly line. The integrated rear floor 2 is then lifted directly to the body-in-white 1 using lifting equipment and connected to the body-in-white 1. This greatly improves the difficulty of operation for operators and increases assembly efficiency. Weak sections 21 are set in front of and behind the components that need protection on the rear floor 2, such as the battery 7, DC-DC module, PDU module, etc. When the vehicle is involved in a rear-end collision, the rear floor 2 will break at the weak section 21 after being squeezed, thereby detaching the component from its original position and avoiding direct hard contact and hard compression with the structure or component in front of or behind the component. This reduces the risk of impact fracture and fire, reduces component damage, and saves maintenance costs.

[0066] The rear floor 2 in this application, as an independent installation and integration component, can be considered a final assembly installation component and can be developed in a differentiated manner. When the vehicle configuration is different, the components installed on the rear floor 2 in the spare tire compartment area will also be different. While the boundary between the rear floor 2 integrated module and the vehicle body remains unchanged, the internal shape, volume, etc., can be adaptively adjusted to meet the storage needs of the vehicle model and improve the flexibility and practicality of the rear floor 2 in the spare tire compartment area.

[0067] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0068] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
