[0025] The following will describe the detailed implementation mode of the present disclosure in conjunction with the accompanying drawings. It should be understood that the detailed implementation mode described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0026] In the present disclosure, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" generally refer to the upper, lower, top, and bottom of the corresponding components in the gravity direction in the use state, "inside, outside" refer to the inside and outside relative to the contour of the component or structure itself, and "front, rear" refer to the direction of vehicle travel. For example, the direction of the vehicle head is the front. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.
[0027] The present disclosure provides a front seat cross beam, including: a main body 2, which is arranged on the floor panel 1 in a direction perpendicular to the vehicle travel direction, and the main body 2 is configured as a cavity structure protruding from the floor panel 1, and a sunken platform is provided on one side of the cavity structure close to the rear row.
[0028] Through the above technical solution, in the front seat cross beam provided by the present disclosure, the main body 2 extends along the arrangement direction of the front seat for installing the seat. The main body 2 is a protruding cavity structure, which can increase the strength of side collisions. A sunken platform is provided on one side of the main body 2 close to the rear row. The sunken part serves as the foot space for the rear row occupants, and the feet can be placed in the foot space, so that the rear row occupants have a larger placement space for their feet, providing better occupant comfort.
[0029] As an alternative implementation mode, as Figures 1-6 shown, a groove 23 that sinks along its extension direction is provided on the main body 2, and the bottom of the groove 23 is in contact with the floor panel 1. For example, it can be welded. A front convex beam 24 and a rear convex beam 25 are respectively formed on the front and rear sides of the groove 23. The height of the rear convex beam 25 is lower than that of the front convex beam 24 to form a sunken platform. By setting the groove 23 in the middle to form the front convex beam 24 and the rear convex beam 25, the side collision strength can be increased. At the same time, the groove 23 is in contact connection with the floor panel 1. At this time, the cross section of the main body 2 is as Figure 4 shown, in a bow shape, to increase the installation strength of the main body 2. In other implementation modes, the main body 2 can also directly sink on one side to form a stepped shape with only two heights.
[0030] Optionally, as Figures 4-6As shown, the upper surface of the main body 2 is configured as an inclined surface that is higher at the front and lower at the rear. The inclined surface can provide a supporting effect on the front part of the soles of the rear-row passengers, enabling the feet of the rear-row passengers to tilt upward when sitting. Compared with placing the feet flat, it can increase the comfort of the feet of the rear-row passengers.
[0031] Among them, as Figures 1-3 shown, an installation platform 27 with a height higher than that of the rear convex beam 25 is provided on the rear convex beam 25. The installation platform 27 is arranged at the center and on both sides of the rear convex beam 25 so that the part at the center under the seat is in a concave state. A bracket 6 is provided on the installation platform 27 for installing the seat and making the seat horizontally arranged. The installation platform 27 is used for installing the seat. The installation platform 27 is higher than the rear convex beam 25 to support the seat and create a foot space between the seat and the rear convex beam 25. The installation platform 27 being located at the center and on both sides of the rear convex beam 25 can prevent the installation platform 27 from obstructing the feet from being placed. On the one hand, the bracket 6 can improve the stiffness of the seat mounting point. On the other hand, since the upper surface of the main body 2 is an inclined surface, the bracket 6 can make the seat horizontally arranged.
[0032] In addition, as Figures 1-3 shown, a boss 26 for connecting the front convex beam 24 and the rear convex beam 25 is provided at the center of the main body 2. The boss 26 increases the connectivity between the front convex beam 24 and the rear convex beam 25 and ensures the strength in the front-rear direction. Especially after installing the seat on the rear convex beam 25, if the force received by the seat only acts on the rear convex beam 25, it will cause insufficient strength of the main body 2 in the front-rear direction. Moreover, the boss 26 is also an inclined surface that is higher at the front and lower at the rear. As Figure 6 shown, the boss 26 is located at the center of the main body 2, that is, between the two front-row seats. There is no seat back blocking there, so even if the boss 26 is higher, it doesn't matter and can still be used as a foot space.
[0033] As an optional implementation manner, as Figures 1-3 shown, the main body 2 includes a main beam 21 and connecting beams 22. Side beams 5 are provided on both sides of the floor panel 1 parallel to the vehicle traveling direction. The main beam 21 is arranged at the center of the two side beams 5. The connecting beams 22 are arranged on both sides of the main beam 21 and connected to the side beams 5. For example, the main beam 21 and the connecting beams 22 are welded. The strength of the main beam 21 is higher than that of the connecting beams 22. For example, the main beam 21 can be made by using hot stamping steel plate technology. Hot stamping steel plate technology means that the steel plate is heated at a high temperature of 950 °C and then formed in one step, and then rapidly cooled, thereby comprehensively improving the strength of the steel plate. The connecting beams 22 are made of ordinary stamping materials. Such an arrangement can save costs on the one hand, and on the other hand, the connecting beams 22 are softer and can play a role in buffering and energy absorption.
[0034] Optionally, as Figures 1-2As shown, the front row seat crossbeam further includes a reinforcement assembly 3. The reinforcement assembly 3 is disposed between the main body 2 and the vehicle head to improve the collision performance. When a collision occurs at the front side of the engine compartment, the reinforcement assembly 3 can better transfer and release the energy of the engine compartment.
[0035] Optionally, a central passage 4 is provided on one side of the floor panel 1 close to the vehicle head. The reinforcement assembly 3 includes a reinforcement plate 31 for connecting with the central passage 4 and a reinforcement crossbeam 32 extending in the same direction as the main body 2 and connected to the side beam 5. The reinforcement crossbeam 32 is connected to the reinforcement plate 31. The energy generated by the collision at the front end of the engine compartment is transferred to the reinforcement crossbeam 32 through the central passage 4 and the reinforcement plate 31, blocked and absorbed by the reinforcement crossbeam 32, and then transferred to the main body 2 through the floor panel 1 and the side beam 5, which can improve the collision performance. At the same time, the setting of the reinforcement crossbeam 32 can also improve the side collision strength of the vehicle.
[0036] Among them, there are two reinforcement plates 31. The two reinforcement plates 31 are used to wrap around both sides of the central passage 4 and extend in the same direction as the central passage 4. The two reinforcement plates 31 wrapping around the central passage 4 make the force more evenly distributed. The reinforcement crossbeam 32 is arranged at an interval from the main body 2, which can play a buffering role and avoid the force on the reinforcement crossbeam 32 directly acting on the main body 2.
[0037] The present disclosure also provides a vehicle, including: a floor panel 1; and the above-mentioned front row seat crossbeam. The front row seat crossbeam is disposed on the floor panel 1. A sunken platform is formed by sinking on one side of the main body 2 of the front row seat crossbeam close to the rear row. The sunken platform part serves as the foot space for the rear row occupants, and the feet can be placed in the foot space, so that the rear row occupants have a larger space for placing their feet, providing better occupant comfort.

However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0039] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.
[0040] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
