The embodiment of the application provides a front floor, as shown in fig. 1 and 2, the front floor includes: the body 1 is provided with a first edge 11 perpendicular to the central channel 2, the central channel 2 and the mounting beam are arranged on the body 1, and the central channel 2 extends along a first direction X; the front floor has a first region, which is a portion of the central passage 2 protruding from the first edge 11 in the first direction X, and a second region, which is a portion of the first edge 11 to the mounting beam, the impact resistance of which is stronger than that of the second region.

In this embodiment, as shown in fig. 1 and 2, the impact resistance of the first area is stronger than that of the second area, so that the first area can absorb a large amount of impact energy when the vehicle collides, resist deformation caused by collision, maintain the shape of the passenger compartment, protect the safety of passengers, and further meet the requirement on the collision performance of the front floor.

Specifically, the first area can be matched with the front coaming assembly of the automobile and is combined with the front girder and the A column, so that the shock resistance of the front part of the passenger cabin is improved, the invasion amount of an engine, a gearbox, a motor and the like to the passenger cabin and a battery during collision is reduced, and therefore passengers are protected, and secondary damage caused by damage to the battery is reduced. The mounting beam is used to mount the front seat so that the second region is a region in front of the front seat that is required to prevent the front seat from leaning forward under inertia and to absorb the remaining crash energy that the first region fails to absorb to protect the occupant.

In a specific embodiment, as shown in fig. 1 and 2, a first included angle is formed between the first area and the horizontal plane, and a second included angle is formed between the second area and the horizontal plane, wherein the first included angle is greater than the second included angle.

Wherein, the first included angle refers to the included angle between the plane with the largest area occupying ratio on the bottom surface of the central channel 2 in the first area and the horizontal plane. The second included angle refers to an included angle between a plane with the largest area occupying ratio on the bottom surface of the body 1 in the second area and a horizontal plane.

In the present embodiment, as shown in fig. 1 and 2, the first region has the first angle with the horizontal plane, so that the impact energy absorbing effect of the first region in the vertical front floor direction can be improved. The first contained angle is greater than the second contained angle for the first region is great in the size of perpendicular preceding floor direction, further improves the first region and to the effect of absorbing the collision energy of following perpendicular preceding floor direction when bumping, and can play the effect of resisting collision deformation jointly with the dash board, prevents that steering mechanism of car from causing the injury to the driver. The second region is gentle with respect to the first region, so that the remaining expansion energy can be absorbed while ensuring riding comfort of the occupant, and deformation of the occupant compartment is prevented to protect the occupant.

Specifically, as shown in fig. 1 and 2, the first included angle is 15 ° to 30 °, and/or the second included angle is 2 ° to 10 °. For example, the first included angle may be specifically 15 °, 18 °, 20 °, 22 °, 25 °, 28 °, 30 °, and the like, and the second included angle may be specifically 2 °, 4 °, 6 °, 8 °, 10 °, and the like.

In this embodiment, as shown in fig. 1 and 2, the degree of the first included angle should not be too large or too small, and if the degree of the first included angle is too small (for example, less than 15 °), the size of the first area along the direction perpendicular to the front floor is small, so that collision energy along the direction perpendicular to the front floor cannot be effectively absorbed, and thus the occupant cannot be effectively protected; if the degree of the first included angle is too large (for example, greater than 30 °), the first region is smaller in size along the first direction X, and collision energy along the first direction X cannot be effectively absorbed, and the occupant cannot be effectively protected. The degree of the second included angle should not be too large or too small, if the degree of the second included angle is too small (for example, smaller than 2 °), the included angle between the first area and the second area is larger, the front section of the central channel 2 is too bent and damaged; if the degree of the second angle is too large (for example, greater than 10 °), the dimension of the second region along the first direction X is affected, and thus the riding comfort of the occupant is affected. Therefore, the degree of the first angle and the degree of the second angle should be selected within a proper range.

In a specific embodiment, as shown in fig. 1 and 3, the mounting beams are provided on the front surface of the body 1, and include a front mounting beam 3 and a rear mounting beam 4, and the front mounting beam 3 and the rear mounting beam 4 each extend in the second direction Y. The front floor has a third area, which is the part between the front mounting beam 3 and the rear mounting beam 4. The front floor has a fourth area, which is the part of the rear mounting beam 4 to the second edge 12. Wherein the second direction Y is perpendicular to the first direction X. The energy level requirements of the four zones decrease gradually from the first zone to the fourth zone.

Note that the front mounting beams 3 mentioned in defining the second, third and fourth regions each refer to the center line of the front mounting beam 3, and the rear mounting beams 4 mentioned each refer to the center line of the rear mounting beam 4.

Specifically, as shown in fig. 1 and 2, along the first direction X, the first region has a first length L1, the second region has a second length L2, the fourth region has a fourth length L4, and the ratio of the first length L1 to the fourth length L4 satisfies: 1.05.ltoreq.L1/L4.ltoreq.1.3, and/or the ratio of the second length L2 to the fourth length L4: L2/L4 is more than or equal to 1.2 and less than or equal to 1.3. For example, L1/L4 may be specifically 1.05, 1.08, 1.1, 1.15, 1.18, 1.2, 1.25, 1.3, etc., L2/L4 may be specifically 1.2, 1.22, 1.25, 1.28, 1.3, etc., and L3/L4 may be specifically 1.1, 1.12, 1.15, 1.18, 1.2, etc.

In the present embodiment, as shown in fig. 1 and 2, the ratio L1/L4 of the first length L1 and the fourth length L4 should not be too large nor too small, and if the ratio L1/L4 is too small (for example, smaller than 1.05), the first region is smaller in size in the first direction X, and collision energy in the first direction X cannot be effectively absorbed; if the ratio is too large (e.g. greater than 1.3), the first region is oversized in the first direction X, and the central passage 2 is weaker and is prone to fracture. The ratio L2/L4 of the second length L2 to the fourth length L4 should not be too large or too small, and if the ratio L2/L4 is too small (for example, less than 1.2), the space in front of the front seat is small, which affects the comfort of riding the occupant, and if the ratio L2/L4 is too large (for example, greater than 1.3), which affects the structure of other positions of the vehicle at a certain vehicle length. Therefore, the first length L1 and the second length L2 should be selected within a reasonable range.

Further, as shown in fig. 2 and 3, the third region has a third length L3 along the first direction X. The second length L2 and the third length L3 satisfy: l2 is more than or equal to L3.

In the present embodiment, as shown in fig. 1 and 3, the seats are mounted on the front mounting beam 3 and the rear mounting beam 4, so that the second length L2 is equal to or greater than the third length L3, which can provide a wider riding environment for the driver and the front passenger, and improve riding comfort.

Specifically, the ratio of the third length L3 to the fourth length L4 satisfies: L3/L4 is more than or equal to 1.1 and less than or equal to 1.2. For example, L3/L4 may be specifically 1.1, 1.12, 1.15, 1.18, 1.2, etc.

In the present embodiment, the ratio of the third length L3 to the fourth length L4 should not be too large or too small, and if the ratio is too small (for example, less than 1.1), the front mounting beam 3 and the rear mounting beam 4 are spaced apart from each other, and it is difficult to stably mount the front seat, and if the ratio is too large (for example, more than 1.2), the front mounting beam 3 and the rear mounting beam 4 are spaced apart from each other, and the mounting of the front seat is also affected. Therefore, the third length L3 should be selected within a reasonable range.

In a specific embodiment, as shown in fig. 4, the mounting beam includes a main body 31 and patch panels 32, the patch panels 32 are disposed on the main body 31, and a plurality of patch panels 32 have the same structure and are used for mounting the front seats.

The existing front and rear mounting beams 3 and 4 are connected to the seat by the nut plates provided thereon, and a plurality of molds are required for production due to the different structures of the plurality of nut plates, resulting in high production costs of the front and rear mounting beams 3 and 4. In the present embodiment, as shown in fig. 4, a patch plate 32 is provided to a main body 31, and a seat is mounted to a front mounting beam 3 and a rear mounting beam 4 via the patch plate 32. The plurality of patch panels 32 are identical in structure, and thus can be produced by sharing one set of molds, so that the production costs of the front mounting beam 3 and the rear mounting beam 4 can be reduced. Further, the main body 31 is produced by thermoforming.

In a specific embodiment, as shown in fig. 1, the central passage 2 comprises a front section 21 and a rear section 22, the strength of the front section 21 being greater than the strength of the rear section 22.

In this embodiment, as shown in fig. 1, the central channel 2 is divided into a front section 21 and a rear section 22, and the front section 21 and the rear section 22 can be made of materials with different strength, so that the materials with high strength can be selected at the position with high strength requirement, and the materials with low strength can be selected at the position with low strength requirement, thereby reducing the cost of the front floor while ensuring the collision performance of the front floor. In addition, the strength requirements of different vehicle types on the front floor are also different, and materials with different strengths can be selected for the front section 21 or the rear section 22 so as to adapt to different vehicle types.

Specifically, the strength of the front section 21 is greater than that of the rear section 22, i.e., the front section 21 is made of a material with high strength, so that collision energy can be effectively absorbed, and safety of passengers is ensured; the rear section 22 is made of a material with low strength, thereby realizing cost reduction and weight reduction.

In a specific embodiment, as shown in fig. 1 and 5, the body 1 of the front floor is provided with a plurality of reinforcing ribs 7, and the reinforcing ribs 7 are distributed on the front surface and the back surface of the body, so that the strength of the body 1 can be effectively improved, and the body 1 is not easy to damage. In particular, the reinforcing bars 7 may be gourd-shaped or other shape.

In a specific embodiment, as shown in fig. 5, the front floor further includes two stringers 5 for mounting a battery, and the two stringers 5 are disposed at intervals on the opposite side of the body 1 and each extend in the first direction X.

In this embodiment, as shown in fig. 5, the battery can be mounted between two stringers 5, and the two stringers 5 can limit the battery, prevent the battery from shaking relative to the body 1, and improve the mounting stability of the battery. Meanwhile, when side collision occurs, the two longitudinal beams 5 can absorb collision energy, and the impact on the battery is reduced, so that the battery is protected.

Specifically, as shown in fig. 5, the front floor further includes a plurality of supporting pieces 6, and the plurality of supporting pieces 6 are disposed on the outer sides of the two stringers 5 away from each other.

In this embodiment, as shown in fig. 5, the plurality of supporting members 6 are disposed on the outer sides of the two longitudinal beams 5 away from each other, so that collision energy can be further absorbed, and difficulty in deformation of the longitudinal beams due to external force is increased, thereby improving the overall strength of the front floor and effectively protecting the battery.

More specifically, as shown in fig. 5, two or more supports 6 may be provided on the outside of each stringer 5.

Further, the two stringers 5 are identical in structure and/or the plurality of supports 6 are identical in structure.

In this embodiment, since the two stringers 5 have the same structure and can be produced by sharing one set of dies, the production cost of the stringers 5 can be reduced, and the production cost of the front floor can be further reduced. Similarly, since the plurality of supporting members 6 have the same structure, a set of dies can be shared for production, so that the production cost of the supporting members 6 can be reduced, and the production cost of the front floor can be further reduced.

In a specific embodiment, as shown in fig. 5, the body 1 has a third edge 13 parallel to the central channel 2, the distance d of the stringers 5 from their nearest third edge 13 in the second direction Y being such that: d is less than or equal to 240mm. For example, the distance d may specifically be 240mm, 220mm, 200mm, 180mm, 150mm, 120mm, 100mm, 80mm, etc.

In the present embodiment, as shown in fig. 5, the distance between the two stringers 5 can be changed by changing the distance d between the stringers 5 and the third edge 13 closest thereto, so that the front floor can be adapted to batteries of different sizes, and the versatility and compatibility of the front floor can be improved.

In particular, in the second direction Y, the distance d between the longitudinal beam 5 and the third edge 13 closest thereto should not be too great, and if the distance d is too great (for example, greater than 240 mm), the distance between the longitudinal beam 5 and the third edge 13 increases, and the strength of the front floor at the third edge 13 decreases, so that the front floor is extremely fragile in the event of a collision of the vehicle, thereby endangering the health of the occupants.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
