Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a front floor assembly and a vehicle. Background Technology
[0002] The vehicle floor assembly is a component of the vehicle's interior structure. It forms the basic framework of the vehicle's interior space, supporting components such as seats, interior trim, and electrical equipment, and providing mounting interfaces for the vehicle's drivetrain and suspension systems.
[0003] The vehicle floor assembly mainly consists of the front floor and seat crossbeams. The front floor, mounted on the vehicle frame, supports components such as seats, interior trim, and electrical equipment. The battery pack is typically located at the bottom of the front floor to lower the vehicle's center of gravity and improve driving stability. In some lower-height models, the battery placement further reduces the vehicle's height; therefore, a central tunnel is located in the center of the front floor to separate the left and right sides of the vehicle and provide a channel for integrated wiring harness routing. Due to the central tunnel, the seat crossbeams are usually designed as separate units, with two units located on either side of the central tunnel and connected to the front floor.
[0004] However, the split seat beams cannot form a continuous structure, resulting in lower structural strength. They are more prone to body deformation in the event of a collision, leading to lower vehicle safety performance. Utility Model Content
[0005] In view of this, the present application provides a front floor assembly and a vehicle to solve the problem that the structural strength of the seat crossbeam is low, which can easily lead to vehicle body deformation and low vehicle safety performance when subjected to a collision.
[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0007] In a first aspect, embodiments of this application provide a front floor assembly. The front floor assembly includes:
[0008] The front floor is configured to be located on top of the power battery, and a portion of the front floor structure arches towards the side away from the power battery to form a housing area. The housing area is located in the middle region of the front floor in the width direction, and the housing area is configured to house the wiring harness.
[0009] A front seat mounting assembly includes a first mounting member disposed on the front floor opposite to the receiving area and configured to connect with a slide rail; both ends of the first mounting member are bent toward the side where the front floor is located and extend toward the two sides of the front floor in the width direction; the first mounting member is connected to the front floor, and a cavity is formed between a portion of the first mounting member and the front floor along the extension direction of the first mounting member.
[0010] The front floor assembly of this application embodiment forms a receiving area by arching a portion of the front floor structure toward the side facing away from the power battery to accommodate the wiring harness. This effectively utilizes the space of the front floor, avoids messy wiring harness arrangement, improves the neatness and space utilization of the vehicle interior, and reduces the gap between the power battery and the front floor on both sides of the receiving area, increasing the space of the passenger compartment. A first mounting member is located on the front floor opposite the receiving area to provide a mounting base for the slide rail, facilitating seat installation. By bending both ends of the first mounting member toward the side where the front floor is located and extending toward the two edges of the front floor in the width direction, compared to directly increasing the thickness or cross-sectional height of the first mounting member, the bending arrangement of the first mounting member can reduce the gap between the first mounting member and the front floor, avoid the first mounting member's arrangement affecting the height of the passenger compartment, and enhance the stability of the connection between the first mounting member and the front floor. At the same time, by forming a cavity between the first mounting member and the front floor, a through structure can be formed between the first mounting member and the front floor on the left and right sides of the receiving area. Since the first mounting component is typically connected to the two sill beams of the vehicle in the extension direction, the cavity can smoothly transfer the load between the two sill beams and absorb and disperse the collision energy when the vehicle is involved in a collision. This increases the space of the passenger compartment, improves the vehicle's safety performance, and reduces the risk of injury to the vehicle body and occupants during a collision.
[0011] In one possible implementation of this application, the front floor assembly further includes a reinforcing member disposed within the cavity and opposite to the receiving area; the reinforcing member is connected to the front floor to divide the cavity into a first cavity and a second cavity in the height direction, the height direction of the cavity being perpendicular to the width direction of the front floor.
[0012] In one possible implementation of this application, the reinforcing member is a reinforcing plate made of high-strength steel.
[0013] In one possible implementation of this application, the reinforcing member has a middle section, a first end, and a second end in the width direction of the front floor, the middle section being opposite to the receiving area; both the first end and the second end are connected to the inner surface of the first mounting member, and the reinforcing member and the first mounting member together define a first cavity; the first cavity is a circumferentially closed cavity.
[0014] In one possible implementation of this application, at least one of the first end and the second end further extends along the inner surface of the first mounting member toward the side opposite to the intermediate section.
[0015] In one possible implementation of this application, the first end and the second end are further bent along the side facing the front floor and connected to the front floor.
[0016] The reinforcement and the front floor together define the second cavity.
[0017] In one possible implementation of this application, the intermediate segment is also connected to the front floor.
[0018] In one possible implementation of this application, the thickness of the first mounting element is less than 2 mm.
[0019] In one possible implementation of this application, the front seat mounting assembly further includes a second mounting member, the front floor having opposing front and rear edges in the length direction, the second mounting member being disposed on the side of the front floor near the front edge relative to the first mounting member; the second mounting member is parallel to the first mounting member and is configured to connect with a slide rail.
[0020] Secondly, embodiments of this application provide a vehicle, including:
[0021] Power battery;
[0022] The aforementioned front floor assembly is located on top of the power battery.
[0023] This application provides a front floor assembly and a vehicle. The front floor assembly includes a front floor and a front seat mounting assembly. The front floor is configured to be located on top of a power battery, and a portion of the front floor structure arches towards the side opposite to the power battery to form a receiving area for accommodating wiring harnesses. This effectively utilizes the space of the front floor, avoids cluttered wiring harness arrangement, improves the neatness and space utilization of the vehicle interior, and reduces the gap between the power battery and the front floor on both sides of the receiving area, increasing the space of the passenger compartment. The front seat mounting assembly includes a first mounting member, which is located on the front floor opposite to the receiving area and configured to connect to a sliding rail. Both ends of the first mounting member are bent towards the side where the front floor is located and extend towards the two sides of the front floor in the width direction. Compared to directly increasing the thickness or cross-sectional height of the first mounting member, the bending configuration of the first mounting member can reduce the gap between the first mounting member and the front floor, avoid the first mounting member's placement affecting the height of the passenger compartment, and enhance the stability of the connection between the first mounting member and the front floor. Along the extension direction of the first mounting member, a cavity exists between a portion of the first mounting member and the front floor, allowing the first mounting member to form a through structure between the left and right sides of the accommodating area and the front floor. Since the first mounting member is typically connected to the two sill beams of the vehicle in the extension direction, the cavity can smoothly transfer loads between the two sill beams during a collision, absorbing and dispersing collision energy. This increases the passenger compartment space while improving vehicle safety performance and reducing the risk of injury to the vehicle body and occupants during a collision.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0040] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0041] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.
[0042] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0043] In embodiments of this application, 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 that element.
[0044] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0045] This application provides a vehicle. The vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.
[0046] In this application embodiment, the type of power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.
[0047] The vehicle also includes the body, which comprises A-pillars, B-pillars, and C-pillars. The A-pillars are located at the front of the vehicle, on either side of the windshield, primarily supporting the windshield and roof. The B-pillars are located in the middle of the vehicle, between the front and rear doors, primarily supporting the roof and sides of the body. The C-pillars are located at the rear of the vehicle, on either side of the rear window, primarily supporting the roof and rear body structure. Through the coordinated action of the A-pillars, B-pillars, and C-pillars, the structural strength of the vehicle body is ensured.
[0048] The vehicle body also includes sill beams, which are located at the bottom of the side of the vehicle, extending along the length of the vehicle and connecting to the B-pillar. The sill beams primarily enhance the structural strength of the vehicle's side profile. In the event of a side collision, the B-pillar and sill beams effectively absorb and disperse collision energy, protecting the safety of the occupants.
[0049] The vehicle also includes a front floor, which is the foundation of the vehicle's internal structure. It is mainly used to provide a mounting base for components such as seats, interior trim, and electrical equipment, and to provide mounting interfaces for the vehicle's drivetrain and suspension systems.
[0050] The vehicle also includes a front seat mounting assembly for installing the car seats. The front seat mounting assembly includes seat crossbeams and slide rails. The seat crossbeams consist of a front crossbeam and a rear crossbeam. The front crossbeam is located at the front of the front floor, near the front edge of the vehicle, and primarily provides stable support for the seat. Slide rails are connected to the front crossbeams, and the car seat is mounted on the slide rails to allow for seat position adjustment, ensuring smoothness and reliability during sliding. The rear crossbeam is located in the middle of the front floor, parallel to the front crossbeam, further enhancing the seat's support strength and connecting to the rear end of the slide rails to ensure the stability of the seat during fore-and-aft sliding.
[0051] In related technologies, the rear crossbeam is connected to the sill beam to provide protection for occupants in the event of a side collision. During a side collision, impact energy can be effectively transferred and dispersed through the connection point between the sill beam and the seat crossbeam, reducing the impact on the occupants.
[0052] The vehicle also includes a battery pack that powers the vehicle's electric system, including the drive motor, electronics, and other auxiliary systems. The battery pack is located at the bottom of the vehicle, beneath the front floor, to lower the vehicle's center of gravity and improve driving stability. Furthermore, the battery pack's safety is enhanced in extreme conditions such as collisions, thanks to the protection provided by the vehicle's body structure.
[0053] In some low-profile vehicles, the placement of the battery pack can further reduce the vehicle's height, even compressing the passenger compartment. To make efficient use of limited space and ensure structural strength, related technologies typically involve arching the central portion of the front floor to form a central tunnel. This central tunnel, located in the center of the vehicle, divides it into left and right sections, with the passenger compartment situated above these sections. Due to this central tunnel configuration, the rear crossbeam requires a split structure, consisting of two independent sections positioned on either side of the central tunnel and connected to the front floor to provide stable support for the seats.
[0054] However, the split design prevents a continuous area between the rear crossbeams. In the event of a collision, this hinders the smooth transfer of impact energy, affecting the vehicle's structural strength. Because there is no continuous area between the rear crossbeams on either side of the center tunnel, impact energy concentrates at the joints of the split rear crossbeams during transmission, leading to localized deformation or damage. This results in lower structural strength for the rear crossbeams, significantly impacting vehicle safety and increasing the risk of injury to occupants.
[0055] Furthermore, while directly thickening or increasing the cross-sectional height of the rear crossbeam can improve its structural strength, it also increases the vehicle's weight and further reduces the usable space in the passenger compartment. This increased weight leads to higher fuel consumption, increased emissions, and reduced vehicle dynamics. Lightweighting requires minimizing unnecessary weight in vehicle design to improve fuel efficiency, reduce emissions, and enhance dynamic performance. Therefore, directly thickening or increasing the cross-sectional height of the rear crossbeam is not conducive to achieving vehicle lightweighting.
[0056] Based on this, this application provides a front floor assembly and a vehicle, aiming to solve the above-mentioned technical problems of the prior art. Specifically, the front floor assembly includes a front floor and a front seat mounting assembly. A portion of the front floor structure arches towards the side of the power battery facing away from the battery to form a receiving area to accommodate wiring harnesses. This effectively utilizes the space of the front floor, avoids messy wiring harness arrangement, improves the neatness and space utilization of the vehicle interior, and reduces the gap between the power battery on both sides of the receiving area and the front floor, increasing the space of the passenger compartment. A first mounting member is disposed at a position opposite to the receiving area on the front floor to provide a mounting base for the slide rail, facilitating seat installation. By bending both ends of the first mounting member towards the side where the front floor is located and extending towards the two edges of the front floor in the width direction, compared to directly increasing the thickness or cross-sectional height of the first mounting member, the bending arrangement of the first mounting member can reduce the gap between the first mounting member and the front floor, avoid the first mounting member's arrangement affecting the height of the passenger compartment, and enhance the stability of the connection between the first mounting member and the front floor. Simultaneously, by creating a cavity between the first mounting component and the front floor, a through-type structure can be formed between the first mounting component and the front floor on both sides of the accommodating area. Since the first mounting component is typically connected to the two sill beams of the vehicle in its extension direction, the cavity can smoothly transfer the load between the two sill beams during a collision, absorbing and dispersing the collision energy. This increases the space of the passenger compartment while improving the vehicle's safety performance and reducing the risk of injury to the vehicle body and occupants during a collision.
[0057] Figure 1 This is a schematic diagram of the front floor assembly provided in an embodiment of this application. Figure 3 for Figure 1 A schematic diagram of the first cross-section along the AA direction in the front floor assembly.
[0058] Please refer to Figure 1 and Figure 3 The front floor assembly 100 provided in this application embodiment includes a front floor 10 and a front seat mounting assembly 20.
[0059] The front floor 10 is located on top of the power battery 300, and a portion of the structure of the front floor 10 arches toward the side away from the power battery 300 to form a receiving area 11. The receiving area 11 is located in the middle region of the front floor 10 in the width direction x, and the receiving area 11 is configured to receive a wiring harness.
[0060] Specifically, wiring harnesses are components used inside vehicles to transmit electrical energy and signals. A wiring harness consists of multiple wires that connect to various electronic devices and electrical systems within the vehicle, ensuring stable power and signal transmission. With the development of vehicle electrification and intelligence, the number and complexity of wiring harnesses are constantly increasing. Therefore, in this embodiment, by forming a receiving area 11 in the front floor 10 to accommodate the wiring harness, cluttered wiring harness arrangements can be avoided, improving the neatness and space utilization of the vehicle's interior space.
[0061] Meanwhile, the housing area 11 also provides protection for the wiring harness, preventing it from being damaged by external factors during vehicle operation and extending its service life. Furthermore, by centrally arranging the wiring harness within the housing area 11, interference between the harness and other components is reduced, lowering the risk of electrical faults caused by loose or damaged wiring harnesses, thereby improving vehicle safety and reliability.
[0062] Specifically, the passenger compartment is located above the front floor 10, and the main usable space for the passengers is located on both sides of the storage area 11. Therefore, by arching part of the front floor 10 toward the side away from the power battery 300 to form the storage area 11, the wiring harnesses that originally needed to occupy the passenger compartment space can be arranged in the storage area 11. It can also reduce the gap between the power battery 300 and the front floor 10 on both sides of the storage area 11, thereby increasing the space of the passenger compartment.
[0063] The height and width of the arch of the front floor 10 facing away from the power battery 300, which is the size of the accommodating area 11, can be adapted to actual needs. This embodiment does not impose any restrictions on this.
[0064] Please refer to Figure 1 and Figure 3 The front seat mounting assembly 20 provided in this embodiment includes a first mounting member 21, which is located on the front floor 10 opposite to the receiving area 11 and is configured to connect with the slide rail 200, thereby providing a stable mounting base for the slide rail 200.
[0065] The first mounting component 21 can also be referred to as the rear crossbeam.
[0066] Specifically, the slide rail 200 supports the seat and allows it to slide along it to accommodate the comfort needs of occupants of different heights. A slider matching the slide rail 200 is located at the bottom of the seat. The slider slides in conjunction with the slide rail 200, allowing the seat to slide along the extension direction of the slide rail 200. By adjusting the seat's position relative to the slide rail 200, occupants can adaptively adjust the seat position according to their height and driving habits, improving driving or riding comfort and safety.
[0067] Please refer to Figure 1 and Figure 3 In this embodiment, there are two slide rails 200. Along the width direction x of the front floor 10, the two slide rails 200 are respectively disposed on both sides of the accommodating area 11, and the extension direction of the slide rails 200 is parallel to the length direction y of the front floor 10.
[0068] Specifically, both ends of the first mounting member 21 are bent toward the side where the front floor 10 is located, and extend toward the two sides of the front floor 10 in the width direction x, thereby increasing the contact area between the first mounting member 21 and the front floor 10, so that the first mounting member 21 can better combine with the front floor 10, thereby enhancing the overall structural stability of the front floor assembly 100.
[0069] The bent portion of the first mounting component 21 can also be fixed to the front floor 10 by bolts or clips to further enhance the stability of the connection.
[0070] Specifically, both ends of the first mounting member 21 are bent towards the side where the front floor 10 is located, meaning the bent portions directly contact the surface of the front floor 10, thereby increasing the contact area between the first mounting member 21 and the front floor 10. Compared to directly increasing the thickness or cross-sectional height of the first mounting member 21, the bent portions reduce the gap between the first mounting member 21 and the front floor 10, thus preventing the installation of the first mounting member 21 from affecting the height of the passenger compartment.
[0071] It should be noted that the bending size at both ends of the first mounting component 21 can be adapted to actual needs, and this embodiment does not impose any restrictions on this.
[0072] Please refer to Figure 1 and Figure 3 In this embodiment, the first mounting member 21 is connected to the front floor 10, and a cavity 40 is provided between a portion of the first mounting member 21 and the front floor 10 along the extension direction of the first mounting member 21, thereby enabling a through structure to be formed between the first mounting member 21 and the front floor 10.
[0073] In this embodiment, the two ends of the first mounting member 21 in the extension direction are respectively connected to the two door sill beams of the vehicle, so that the first mounting member 21 and the door sill beams form an integral structure. When the vehicle collides, the cavity 40 can smoothly transfer the load between the two door sill beams and absorb and disperse the collision energy.
[0074] Specifically, when a vehicle collision occurs, as the collision energy is transferred to the first mounting member 21, the air inside the cavity 40 is compressed, generating a certain amount of resistance. This resistance can dissipate some of the collision energy. Simultaneously, the structure of the cavity 40 allows the collision energy to be evenly distributed along its length, rather than concentrated at a single point. This avoids stress concentration, improves the structural strength of the first mounting member 21, and thus, while increasing the passenger compartment space, enhances the vehicle's safety performance and reduces the risk of injury to the vehicle body and occupants during a collision.
[0075] Figure 2 for Figure 1 A schematic diagram of the structure of the middle reinforcing member 30.
[0076] Please refer to Figures 1 to 3 In some embodiments of this application, the front floor assembly 100 further includes a reinforcing member 30 disposed within the cavity 40 and opposite to the receiving area 11; the reinforcing member 30 is connected to the front floor 10 to divide the cavity 40 into a first cavity 41 and a second cavity 42 in the height direction z, wherein the height direction z of the cavity 40 is perpendicular to the width direction x of the front floor 10.
[0077] Specifically, in this embodiment, the reinforcing member 30 is configured to divide the cavity 40 into a first cavity 41 and a second cavity 42 in the height direction z. Thus, when a vehicle collision occurs, the collision energy is dispersed into the first cavity 41 and the second cavity 42 during transmission. When the air in the first cavity 41 and the second cavity 42 is compressed, it generates resistance, which dissipates some of the collision energy. Simultaneously, the reinforcing member 30 also absorbs collision energy during the collision, thereby further reducing the direct impact of the collision energy on the vehicle body through dual energy absorption. This further prevents vehicle body deformation, improves vehicle safety performance, and reduces the risk of injury to the vehicle body and occupants during a collision.
[0078] In this embodiment, the reinforcement 30 is connected to the front floor 10 to ensure that the reinforcement 30 can stably absorb the collision energy during the collision process and will not be displaced or loosened due to the force.
[0079] The connection method between the reinforcing member 30 and the front floor 10 can be adapted to actual needs, and this embodiment does not impose any restrictions on this. For example, the reinforcing member 30 and the front floor 10 are connected by bolts.
[0080] Please refer to Figures 1 to 3 In some embodiments of this application, the reinforcing member 30 is a reinforcing plate made of high-strength steel, which can further increase the structural strength of the front floor assembly 100 and further improve the safety performance of the vehicle.
[0081] High-strength steel is a type of steel with high strength and good toughness, which can provide higher tensile strength and yield strength without significantly increasing the thickness of the material.
[0082] It should be noted that the thickness of the reinforcing member 30 can be adapted to actual needs, and this embodiment does not impose any restrictions on it. For example, the thickness of the reinforcing member 30 can be 1.6 mm.
[0083] By using high-strength steel to make the reinforcing member 30, the structural strength is ensured while meeting the lightweight design requirements of the vehicle. High-strength steel requires a much smaller material thickness than ordinary steel for the same strength requirements. Therefore, although the front floor assembly 100 in this embodiment adds the reinforcing member 30, the overall material usage of the front floor assembly 100 does not increase significantly. In contrast, directly thickening the first mounting member 21 would not only increase material usage but also increase the overall weight of the front floor assembly 100. While directly replacing the first mounting member 21 with high-strength steel could improve structural strength, it would significantly increase production and processing costs. Therefore, this embodiment provides the reinforcing member 30 for localized reinforcement, which can improve structural strength and meet the lightweight design requirements without significantly increasing costs.
[0084] Please refer to Figures 1 to 3 In some embodiments of this application, the reinforcing member 30 has a middle section 32, a first end 31 and a second end 33 in the width direction x of the front floor 10, the middle section 32 being opposite to the accommodating area 11; the first end 31 and the second end 33 are both connected to the inner surface of the first mounting member 21, and the reinforcing member 30 and the first mounting member 21 together define a first cavity 41, the first cavity 41 being a circumferentially closed cavity.
[0085] Specifically, in this embodiment, the middle section 32 of the reinforcing member 30 is disposed opposite to the accommodating area 11 to avoid interference with the accommodating area 11. The first end 31 and the second end 33 are located on both sides of the middle section 32 and are connected to the inner surface of the first mounting member 21 to support the first mounting member 21. This can improve the structural strength of the entire front floor assembly 100, thereby effectively transmitting and dispersing the impact force received by the first mounting member 21 when the vehicle is involved in a collision, further improving the safety performance of the vehicle.
[0086] Please refer to Figures 1 to 3 In this embodiment, the reinforcing member 30 and the first mounting member 21 together define the first cavity 41, and the first cavity 41 is a circumferentially closed cavity.
[0087] The first end 31 and the second end 33 respectively form a first cavity 41 with the front floor 10. The first cavity 41 formed between the first end 31 and the front floor 10 and the second end 33 and the front floor 10 are located on both sides of the accommodating area 11. When a vehicle collision occurs, the collision energy is transferred to the front floor assembly 100. The closed first cavity 41 allows the collision energy to be effectively absorbed and dispersed within the cavity, rather than directly acting on the vehicle body. This significantly reduces the direct impact of the collision energy on the vehicle body, reduces the possibility of vehicle body deformation, and improves the vehicle's safety performance.
[0088] Figure 4 for Figure 1 A schematic diagram of a second cross-section along the AA direction in the front floor assembly 100.
[0089] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments of this application, at least one of the first end 31 and the second end 33 extends along the inner surface of the first mounting member 21 toward the side opposite to the intermediate section 32.
[0090] Specifically, in this embodiment, both the first end 31 and the second end 33 extend along the inner surface of the first mounting member 21 toward the side away from the middle section 32, thereby increasing the contact area between the reinforcing member 30 and the first mounting member 21, thereby further enhancing the structural stability of the front floor assembly 100, so that the entire front floor assembly 100 can more evenly distribute stress when subjected to external force, avoiding structural damage caused by stress concentration.
[0091] The distances that the first end 31 and the second end 33 extend along the inner surface of the first mounting member 21 can be adapted to actual needs, and this embodiment does not impose any restrictions on this.
[0092] In some embodiments, only the first end 31 may extend along the inner surface of the first mounting member 21 toward the side opposite to the intermediate section 32, or only the second end 33 may extend along the inner surface of the first mounting member 21 toward the side opposite to the intermediate section 32. This embodiment does not impose any restrictions on this.

[0094] Please refer to Figure 1 , Figure 2 and Figure 5In some embodiments of this application, the first end 31 and the second end 33 are also bent along the side that faces the front floor 10 and connected to the front floor 10, and the reinforcing member 30 and the front floor 10 together define the second cavity 42.
[0095] Specifically, in this embodiment, both the first end 31 and the second end 33 are bent toward the side where the front floor 10 is located. The bent portion can directly contact and connect with the front floor 10, thereby increasing the contact area and connection points between the reinforcing member 30 and the front floor 10, so that the reinforcing member 30 can be firmly fixed to the front floor 10, further increasing the structural stability of the front floor assembly 100.
[0096] At the same time, the bent portion can also support the reinforcing member 30, thereby supporting the first mounting member 21, which further enhances the structural strength of the front floor assembly 100.
[0097] Specifically, this embodiment does not limit the bending distance of the first end 31 and the second end 33, and can be adapted to meet actual needs.
[0098] Please refer to Figure 1 , Figure 2 and Figure 5 In this embodiment, the reinforcing member 30 and the front floor 10 together define a second cavity 42. When a collision occurs, the collision energy is transferred to the front floor assembly 100. The first cavity 41 allows the collision energy to be effectively absorbed and dispersed within itself, reducing the direct impact of energy on the vehicle body. Furthermore, the second cavity 42 further optimizes the absorption and dispersion of collision energy. Since the second cavity 42 is located between the reinforcing member 30 and the front floor 10, it provides additional buffer space, allowing the collision energy to be further absorbed and dispersed during transmission. Thus, through this dual-cavity structure, the direct impact of collision energy on the vehicle body can be reduced more effectively during a collision, decreasing the possibility of vehicle body deformation, thereby improving the vehicle's safety performance during a collision and enhancing the safety of the occupants.
[0099] Furthermore, in some embodiments, the reinforcement 30, the first mounting member 21, and the front floor 10 may also jointly define the second cavity 42, and this embodiment does not impose any restrictions on this.
[0100] Figure 6 for Figure 1 A schematic diagram of the fourth cross section along the AA direction in the front floor assembly 100.
[0101] Please refer to Figure 6Specifically, the middle section 32 of the reinforcing member 30 is located between the first mounting member 21 and the accommodating area 11, and neither of them contacts the inner surface of the first mounting member 21 nor the outer surface of the accommodating area 11. The two ends of the first end 31 contact the first mounting member 21 and the front floor 10 respectively, and the two ends of the second end 33 also contact the first mounting member 21 and the front floor 10 respectively. This allows the middle section 32 to form a sub-cavity with the first mounting member 21, and the middle section 32 can also form another sub-cavity directly with the front floor 10, thus dividing the second cavity 42 into two cavities. Through the triple cavity structure, the direct impact of collision energy on the vehicle body can be reduced more effectively during a collision, reducing the possibility of vehicle body deformation, thereby improving the safety performance of the vehicle during a collision and improving the safety of the occupants.
[0102] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments of this application, the intermediate segment 32 is also connected to the front floor 10.
[0103] Specifically, in this embodiment, the middle section 32 is opposite to the accommodating area 11 and is in direct contact with and connected to the outer surface of the accommodating area 11, thereby enhancing the stability between the reinforcing member 30 and the front floor 10. At the same time, the accommodating area 11 can also provide support for the middle section 32, further reducing the direct impact of collision energy on the entire vehicle body during a collision.
[0104] In this embodiment, the middle section 32 can be welded to the front floor 10 to enhance the stability of the connection between the middle section 32 and the front floor 10, so that the collision energy can be transferred and dispersed more effectively during a collision.
[0105] In other embodiments, the connection relationship between the intermediate section 32 and the front floor 10 can be adapted according to actual needs, and this embodiment does not impose any restrictions on this.
[0106] It should also be noted that in some embodiments, the middle section 32 may only abut against the front floor 10 without being directly connected. This embodiment does not impose any restrictions on this.
[0107] In some other embodiments, the intermediate section 32 may also abut against the inner surface of the first mounting member 21 to improve the support effect on the first mounting member 21 and further improve the stability of the support. This embodiment does not impose any restrictions on this.
[0108] Please refer to Figure 1 and Figure 5In some embodiments of this application, the thickness of the first mounting member 21 is less than 2 mm. For example, the thickness of the first mounting member 21 can be 1.8 mm, 1.5 mm, 1.3 mm, or 1.0 mm. This allows the first mounting member 21 to reduce the overall weight while meeting the basic structural strength requirements, thus satisfying the lightweight design requirements of the vehicle. When the thickness of the first mounting member 21 exceeds or equals 2 mm, although it increases the structural strength of the first mounting member 21, it also leads to an increase in the overall weight of the first mounting member 21, which is detrimental to the lightweight design of the vehicle.
[0109] It should be noted that, in this embodiment, the cavity 40 can provide a buffering effect when a vehicle collides, absorbing and dispersing the collision energy, thereby ensuring the stability and reliability of the front floor assembly 100. Therefore, even if the thickness of the first mounting member 21 is adaptively reduced, the safety performance of the vehicle can still be guaranteed.
[0110] In other embodiments, the thickness of the first mounting member 21 can be adapted to actual needs, and this embodiment does not impose any restrictions on this.
[0111] Please refer to Figure 1 In some embodiments of this application, the front seat mounting assembly 20 further includes a second mounting member 22. The front floor 10 has opposing front and rear edges in the longitudinal direction y. Relative to the first mounting member 21, the second mounting member 22 is located on the side of the front floor 10 near the front edge; that is, the second mounting member 22 can also be referred to as a front crossbeam. The second mounting member 22 is parallel to the first mounting member 21 and is configured to connect to the slide rail 200.
[0112] Specifically, the second mounting member 22 is located on the side of the front floor 10 near the front edge and is parallel to the first mounting member 21, thereby providing a mounting point for the slide rail 200. This allows the slide rail 200 to obtain more uniform support in the length direction y of the front floor 10, reducing the deformation and shaking of the slide rail 200 during use, thereby improving the installation strength of the seat and ensuring the stability and safety of the seat during use.
[0113] Please refer to Figure 1 and Figure 3 In this embodiment, there are two second mounting members 22. The two second mounting members 22 are located on both sides of the receiving area 11 along the width direction x of the front floor 10, so as to provide mounting points and support for the two slide rails 200 respectively.
[0114] Please refer to Figure 1 and Figure 3 Secondly, embodiments of this application provide a vehicle including a power battery 300 and the aforementioned front floor assembly 100, the front floor assembly 100 being disposed on top of the power battery 300.
[0115] The front floor assembly 100 includes a front floor 10 and a front seat mounting assembly 20. The front floor 10 is configured to be located on top of the power battery 300, and a portion of the front floor 10 arches towards the side opposite to the power battery 300 to form a receiving area 11. The front seat mounting assembly 20 includes a first mounting member 21, which is located on the front floor 10 opposite to the receiving area 11 and is configured to connect to a slide rail 200. Both ends of the first mounting member 21 are bent toward the side where the front floor 10 is located, and extend toward the two sides of the front floor 10 in the width direction x. Compared to directly increasing the thickness or cross-sectional height of the first mounting member 21, the bending configuration of the first mounting member 21 can reduce the gap between the first mounting member 21 and the front floor 10, avoid the first mounting member 21 affecting the height of the passenger compartment, and enhance the stability of the connection between the first mounting member 21 and the front floor 10. Along the extending direction of the first mounting member 21, a cavity 40 is provided between a portion of the first mounting member 21 and the front floor 10, allowing the first mounting member 21 to form a through structure between the left and right sides of the accommodating area 11 and the front floor 10. Since the first mounting member 21 is typically connected to the two sill beams of the vehicle in the extending direction, the cavity 40 can smoothly transfer the load between the two sill beams during a collision, absorbing and dispersing the collision energy. This increases the space of the passenger compartment while improving the vehicle's safety performance and reducing the risk of injury to the vehicle body and occupants during a collision.

[0117] It is understood that the vehicle in this embodiment has the beneficial effects of the front floor assembly in any of the above embodiments, so they will not be described in detail here.
